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.

Whiteflies form a major threat for many vegetable and ornamental crops. The adults can be recognized by their waxy wings. Whiteflies have well developed needle-like mouthparts. They extract sap from the underside of plant leaves and secrete honeydew. This honeydew, in turn, is a nutrient source for sooty moulds.
The female lays her eggs on the underside of young leaves. If she has not yet mated, all of the eggs will develop into males.
The eggs have a white/yellowish colour, are oblong shaped and are often deposited in circles. After one or two days, they become darker in colour.
The nymphs that emerge from the eggs are known as ‘crawlers’. Crawlers move around for several hours before settling on the leaf. They moult into their second stage and become immobile. The nymph starts to feed and begins to produce honeydew. Two further stages will follow. The nymph is flat at first, later changing into an oval, box-shaped pupa with hairs. Eventually the adult emerges.
Soon after emerging, wax is secreted over the entire body.
Adults immediately begin to penetrate the leaf with their mouth parts to feed on plant sap.

Aphids inflict serious damage to a variety of crops. They are notorious virus vectors and have an enormous reproductive capacity.
There are lots of different coloured species and they occur in all kinds of crops. The nymphs and adults extract food materials from the plant and disturb the balance of the plant’s growth hormones.
It can result in deformed leaves or even the death of young plants. Aphids secrete honeydew which is a nutrient source for sooty moulds. Their saliva can also induce strong allergic reactions such as malformations of the growing tips. The aphid in this video is the most important vector of viruses and is thus feared by many growers. When reproduction is asexual, the young aphids are born as developed nymphs. They immediately start to feed on plant sap and grow rapidly. Aphids moult four times before reaching adulthood.
With each moult they shed white skin, betraying their presence in the crop. Adult aphids can have different appearances. They can vary in colour and can be winged or wingless. The most effective method to control aphids depends on species, crop and climate.

Spider mite infestations affect many crops throughout the world. With their great reproductive capacity they can destroy plants rapidly. Adult spider mites can be red, orange, yellow, green or brown in colour. Both males and females usually have two large black spots. That is why they are called ‘two-spotted spider mite’. Spider mites cause damage to the host plant by feeding on plant tissue and plant sap. They mainly occur on the underside of leaves where they suck out the contents of the cells. These dead cells become yellow.As damage increases whole leaves turn yellow, and eventually the plant may die. Nymphs and adults also produce webs, and plants can be completely covered by them. They can reproduce sexually as well as asexually. Eggs are laid on the underside of the leaves.The larvae that emerge from the eggs are virtually colourless with two dark red eyes. Once they start feeding they become light green, brownish yellow or even dark green. The two dark spots also develop on the middle of the body. Once sufficient food is consumed, they become inactive and develop into protonymphs. Another feeding and resting period follows, that leads to a moult. The deutonymph emerges. After another moult the adult mite appears. With each moult spider mites shed their skin. The colour of the adults often depends on the crop on which they occur. The intensive use of chemicals has led to many spider mite populations developing resistance to pesticides.

Biological life cycle
In biology, a life cycle is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, and/or sexual reproduction.
In some organisms, different "generations" of the species succeed each other during the life cycle. For plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two.
Life cycles that include sexual reproduction involve alternating haploid (n) and diploid (2n) stages, i.e., a change of ploidy is involved. To return from a diploid stage to a haploid stage, meiosis must occur. In regard to changes of ploidy, there are 3 types of cycles:

Life
Life is a characteristic distinguishing physical entities having biological processes (such as signaling and self-sustaining processes) from those that do not, either because such functions have ceased (death), or because they lack such functions and are classified as inanimate. Various forms of life exist such as plants, animals, fungi, protists, archaea, and bacteria. The criteria can at times be ambiguous and may or may not define viruses, viroids or potential artificial life as living. Biology is the primary science concerned with the study of life, although many other sciences are involved.
Throughout history there have been many theories about life including materialism, hylomorphism and vitalism. Even today it is a challenge for scientists and philosophers to define life. The smallest contiguous unit of life is called an organism. Organisms are composed of one or more cells, undergo metabolism, maintain homeostasis, can grow, respond to stimuli, reproduce (either sexually or asexually) and, through evolution, adapt to their environment in successive generations. A diverse array of living organisms can be found in the biosphere of Earth, and the properties common to these organisms are a carbon- and water-based cellular form with complex organization and heritable genetic information.

Aphids inflict serious damage to a variety of crops. They are notorious virus vectors and have an enormous reproductive capacity.
There are lots of different coloured species and they occur in all kinds of crops. The nymphs and adults extract food materials from the plant and disturb the balance of the plant’s growth hormones.
It can result in deformed leaves or even the death of young plants. Aphids secrete honeydew which is a nutrient source for sooty moulds. Their saliva can also induce strong allergic reactions such as malformations of the growing tips. The aphid in this video is the most important vector of viruses and is thus feared by many growers.

When reproduction is asexual, the young aphids are born as developed nymphs. They immediately start to feed on plant sap and grow rapidly. Aphids moult four times before reaching adulthood.
With each moult they shed white skin, betraying their presence in the crop. Adult aphids can have different appearances. They can vary in colour and can be winged or wingless. The most effective method to control aphids depends on species, crop and climate.

Spider mite infestations affect many crops throughout the world. With their great reproductive capacity they can destroy plants rapidly. Adult spider mites can be red, orange, yellow, green or brown in colour. Both males and females usually have two large black spots. That is why they are called ‘two-spotted spider mite’. Spider mites cause damage to the host plant by feeding on plant tissue and plant sap. They mainly occur on the underside of leaves where they suck out the contents of the cells. These dead cells become yellow.As damage increases whole leaves turn yellow, and eventually the plant may die. Nymphs and adults also produce webs, and plants can be completely covered by them. They can reproduce sexually as well as asexually. Eggs are laid on the underside of the leaves.The larvae that emerge from the eggs are virtually colourless with two dark red eyes. Once they start feeding they become light green, brownish yellow or even dark green. The two dark spots also develop on the middle of the body. Once sufficient food is consumed, they become inactive and develop into protonymphs. Another feeding and resting period follows, that leads to a moult. The deutonymph emerges. After another moult the adult mite appears. With each moult spider mites shed their skin. The colour of the adults often depends on the crop on which they occur. The intensive use of chemicals has led to many spider mite populations developing resistance to pesticides.

Life Cycle, Sieges Even
Life Cycle
New life dawns - the inception of another link in a
profound process
Alteration and progress, nothing remains the same
Like a from from the egg to the tadpole to the final
stage
Everything develops, learns, there's always reason almost
rhyme!
Like a spirit staircase that someday, somehow will end
Even the world's life cycle ends when progression's
altered (synthetically)
I stalked the blissful fields of springtime, I comprehend
and I remind
And I will taste the bleary bleakness of autumn time, in
due time I will find!
Genesis, search, consumation - no living thing is
extempted
Confined knowledge cannot understand - harmonious
symbiosis!
Life cycles - almost everywhere!
Life cycles - permanent progress!
