This video is about Parts of a Cannabis Flower. It is meant to be an educational and study tool for Chunk and anyone else that benefits from it. I go into some detail of the individual parts of the physical cannabis flower. to do this I actually disect a flower and magnify each part, or at least the parts I can find. Dioecious Carpellate / Staminate: Inflorescence Gymnosperms - Naked seeds Pinophyta : Pines Cycadophyta: look like palms Gingkophyta: One species Gnetophyta: Welwitschia: Found in africa Ephedra Magnoliophyta (angiosperms): Flowering plants with fruits Seeds, Pollen, Ovule Female gametophyte (in an angiosperm) Pollen (of an angiosperm) Monocots vs. dicots Stamen: anther, filament Pistil: style, ovary, stigma Pollen, tube nucleus, generative nucleus Pollination: double fertilization Zygote, endosperm Receptacle Petals, sepals, corolla & calyx Peduncle & pedicel Inferior ovary, superior ovary Inflorescence: raceme, spike, umbel, corymb Fruit: fleshy & dry Pericarp: Exocarp, mesocarp, endocarp Berry: Drupe, Pepo, Hesperidium, Pome Dehiscent: legume, follicle, capsules Indehiscent: nut, achene, samara Aggregate and multiple fruits Seed: endosperm, cotyledons, embryo, seed coat Germination: radicle, plumule, epicotyl & hypocotyl Vivipary, parthenocarpy, apomixis Apical meristems: root tips, axillary and shoot tips Protoderm, ground meristem and procambium Secondary meristems: Cork cambium and vascular cambium Parenchyma, collenchyma Sclerenchyma: fibers and sclerids Nodes, inner nodes, leaf scars, lenticels Monocot stems vs. dicot stems Vascular bundles, cortex, pith, epidermis Xylem: fibers, vessels and tracheids Phloem: fibers, sieve tubes and companion cells Primary & secondary xylem and phloem Annual rings Vascular rays Heartwood, sapwood Cork, cork cambium, phelloderm Xylem, vascular cambium, phloem Bark Rhizome, corm, tendril, thorn Root Cap & Regions of cell division, elongation and maturation Root hairs Monocot roots vs. dicot roots Fibrous roots and taproots Endodermis, pericycle and casparian strips Absorption, Cohesion, Transpiration Root modifications: Prop, Pneumatophores, Buttress, Contractile and storage roots Mycorrhizae & root nodules Leaf: petiole, blade Pinnate vs. Palmate Simple vs. Compound Opposite, Alternate, & Whorled Monocot vs. dicot venation in leaves Stomata Dehiscence Ecology Community Ecosystem Distribution Logistic growth Exponential growth Carrying capacity Symbiosis Commensalism Parasitism Mutualism Trophic structure Producers Consumers (primary secondary, etc.) Decomposers 10% rule Nutrient cycling
