Hank introduces us to nonvascular plants - liverworts, hornworts & mosses - which have bizarre features, kooky habits, and strange sex lives. Nonvascular plants inherited their reproductive cycle from algae, but have perfected it to the point where it is now used by all plants in one way or another, and has even left traces in our own reproductive systems.

Script:
Today we are going to talk about the concept of Alternation of Generations, with a focus on angiosperms, or flowering plants. This is part 1 of a 5-part series.
The alternation of Generations is a phrase that describes the life cycle of a plant. The life cycle of a plant is divided into two phases: a sexual phase and a growth phase. Because this is a cycle, you can start at any point, but we are going to start with the sexual phase.
The goal of the sexual phase is to produce gametes. Gametes are male and female sex cells that combine in pairs to form a zygote, or fertilized egg. In plants, the male gamete is analogous to sperm and the female gamete is analogous to an egg. The male gamete is called a microspore, and the female gamete is called a megaspore. They are collectively referred to as spores.
In angiosperms, the male and female gametes fuse together and eventually form a seed. This seed begins the growth phase. The new plant grows from the seed and matures until it can produce sex organs. When the sex organs form, the sexual phase can begin again, and the cycle is completed.
In plants, the sexual phase is called the gametophyte phase, and the sexual organs are called the gametophytes. The growth phase is called the sporophyte phase, and the rest of the plant, everything excluding the gametophytes, is called a sporophyte. We’ll now identify the gametophytes and sporophyte on a flower. Here we see a side view of your typical flower. The male gametophyte is found within this part of the plant, called the anther. The female gametophyte is found in this part of the plant, and is called the ovary. In summary, the gametophytes of the flower are called the anther and the ovary, and their job is to produce gametes. The rest of the plant, or the plant in growth phase, is called the sporophyte. The sporophyte’s job is to produce the anther and ovary so it can reproduce.
Let’s take a look at an actual flower for reference. This is a Lily, and I’ll outline the anthers in black. Now, I’ll outline the approximate location of the ovary. The ovule within the ovary hosts the female gamete.
I’ll now give you a ten-second summary of what we’ve learned.
Each stage in the cycle exists to create something that perpetuates the next stage. The gametophyte creates gametes that fuse to form the seed. The sporophyte grows a plant which can support the sex organs.

The difference between sporophyte and gametophyte are sporophyte is an independent plant with diploid chromosome number whereas by meiosis and fertilization, life cycle of a plant divides into sporophyte generation and gametophyte generation. These haploid spores eventually grow as multicellular, haploid gametophytes which give rise to the next gametophyte generation. Sporophyte phase produces spores, while below information will help you to get some more though about the subject . Best answer in plants and algae that undergo alternation of generations, a gametophyte is the multicellular structure, or phase, that is haploid, best answer a gametophyte is produced during meiosis and is haploid, half the normal number of chromosomes, since when it gets together anyway if you want for more info, you would better continue reading.

Sporophyte
A sporophyte (/spɔːroʊˌfaɪt/) is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the Gymnosperms and flowering plants (Angiosperms), the sporophyte phase is more prominent than the gametophyte, and is the familiar green plant with its roots, stem, leaves and cones or flowers. In flowering plants the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.
The sporophyte produces spores (hence the name) by meiosis, a process also known as "reduction division" that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte. Both the spores and the resulting gametophyte are haploid, meaning they only have one set of chromosomes. The mature gametophyte produces male or female gametes (or both) by mitosis. The fusion of male and female gametes produces a diploid zygote which develops into a new sporophyte. This cycle is known as alternation of generations or alternation of phases.

Today we are going to talk about the concept of Alternation of Generations, with a focus on angiosperms, or flowering plants. This is part 1 of a 5-part series.
The alternation of Generations is a phrase that describes the life cycle of a plant. The life cycle of a plant is divided into two phases: a sexual phase and a growth phase. Because this is a cycle, you can start at any point, but we are going to start with the sexual phase.
The goal of the sexual phase is to produce gametes. Gametes are male and female sex cells that combine in pairs to form a zygote, or fertilized egg. In plants, the male gamete is analogous to sperm and the female gamete is analogous to an egg. The male gamete is called a microspore, and the female gamete is called a megaspore. They are collectively referred to as spores.
In angiosperms, the male and female gametes fuse together and eventually form a seed. This seed begins the growth phase. The new plant grows from the seed and matures until it can produce sex organs. When the sex organs form, the sexual phase can begin again, and the cycle is completed.
In plants, the sexual phase is called the gametophyte phase, and the sexual organs are called the gametophytes. The growth phase is called the sporophyte phase, and the rest of the plant, everything excluding the gametophytes, is called a sporophyte. We’ll now identify the gametophytes and sporophyte on a flower. Here we see a side view of your typical flower. The male gametophyte is found within this part of the plant, called the anther. The female gametophyte is found in this part of the plant, and is called the ovary. In summary, the gametophytes of the flower are called the anther and the ovary, and their job is to produce gametes. The rest of the plant, or the plant in growth phase, is called the sporophyte. The sporophyte’s job is to produce the anther and ovary so it can reproduce.
Let’s take a look at an actual flower for reference. This is a Lily, and I’ll outline the anthers in black. Now, I’ll outline the approximate location of the ovary. The ovule within the ovary hosts the female gamete.
I’ll now give you a ten-second summary of what we’ve learned.
Each stage in the cycle exists to create something that perpetuates the next stage. The gametophyte creates gametes that fuse to form the seed. The sporophyte grows a plant which can support the sex organs.

The alternation of Generations is a phrase that describes the life cycle of a plant. The life cycle of a plant is divided into two phases: a sexual phase and a growth phase. Because this is a cycle, you can start at any point, but we are going to start with the sexual phase.
The goal of the sexual phase is to produce gametes. Gametes are male and female sex cells that combine in pairs to form a zygote, or fertilized egg. In plants, the male gamete is analogous to sperm and the female gamete is analogous to an egg. The male gamete is called a microspore, and the female gamete is called a megaspore. They are collectively referred to as spores.
In angiosperms, the male and female gametes fuse together and eventually form a seed. This seed begins the growth phase. The new plant grows from the seed and matures until it can produce sex organs. When the sex organs form, the sexual phase can begin again, and the cycle is completed.
In plants, the sexual phase is called the gametophyte phase, and the sexual organs are called the gametophytes. The growth phase is called the sporophyte phase, and the rest of the plant, everything excluding the gametophytes, is called a sporophyte. We’ll now identify the gametophytes and sporophyte on a flower. Here we see a side view of your typical flower. The male gametophyte is found within this part of the plant, called the anther. The female gametophyte is found in this part of the plant, and is called the ovary. In summary, the gametophytes of the flower are called the anther and the ovary, and their job is to produce gametes. The rest of the plant, or the plant in growth phase, is called the sporophyte. The sporophyte’s job is to produce the anther and ovary so it can reproduce.
Let’s take a look at an actual flower for reference. This is a Lily, and I’ll outline the anthers in black. Now, I’ll outline the approximate location of the ovary. The ovule within the ovary hosts the female gamete.
I’ll now give you a ten-second summary of what we’ve learned.
Each stage in the cycle exists to create something that perpetuates the next stage. The gametophyte creates gametes that fuse to form the seed. The sporophyte grows a plant which can support the sex organs.

Life on Earth 009 - Plants
Paul surveys the Kingdom Plantae. He begins with a brief description of the phylogeny of land plants. He then describes the defining characteristics of plants, including cell walls, embryophytes, alternation of generation and photosynthesis. He briefly describes the sporophyte and the gametophyte. He finishes with brief discussion of plant evolution and includes major divisions, like bryophytes, ferns, gymnosperms, and angiosperms.

Saprophyte
Cybervoid
It was just another fantasy
made in virtual reality
By the sensors you enjoyed the game
See the tragedy the whole thing became
The machine took your mind away
from its mortal frame
'cause to live in a human way
has become its aim
Face the void
Prepare for the fight
Victimized
by cruel megabytes
Feel the cybervoid
Against the machine cycle time you race
Data curse your soul
You're lost in cyberspace
with no control
Face the void
Prepare for the fight
Victimized
by cruel megabytes
Direct access to madness
throught permutation
Cybervoid
The machine will curse your mind
You're left separated from mankind
Cybervoid
The machine has made you blind
You're dream of a lifetime left behind
You have lived in a fantasy
but the dream's destroyed
Your spirit is doomed to roam
in the cybervoid
Face the void
Prepare for the fight
