leaves

stem
The main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean.
roots
the usually underground organ that lacks buds or leaves
photosynthesis
the process in which plants make glucose from the sun
seed
structure that contains a young developing plant that stores food
seed coat
one or more protective layers that surround the seed
cotyledon
A seed leaf that stores food in the form of starch and protein for use by the embryo
embryo
young multi-cellular organism before it emerges from the seed, baby plant
seed dispersal
the spreading of the seed
germination
the growing of seeds
vascular plants
plants with true vascular tissue
non-vascular
plants that lack a well developed system of tubes for transporting water and other materials
what angiosperms do
have flowers, slender or wide leaves, cactus, wheat, sources of food closing medicine, seeds enclose in food
what gymnosperms do
no flowers, needle like or scale like leaf, don't have a protective fruit, cycads, gingkoes, conifers, geophytes, oldest type of seed plant
xylem
the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem
phloem
the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves
pistil
female reproductive parts
stamen
male reproductive parts
anther
male parts of the flower that makes pollen
stigma
sticky part of the flower that traps the pollen
filament
thin structure that connects the anther to the ovary
sepals
protects the developing flower
petals
The modified leaves surrounding the reproductive parts. The scent and color attracts pollinators
ovary
contains ovules where the seed develops
style
pollen tube
cone (gymnosperms)
gymnosperms reproductive structure
ovule
structure on female cone that contains an egg cell
pollen (gymnosperms)
structure on male cone that contains sperm
pollination
The transfer of pollen by wind, water or animals
fertilization (gymnosperms)
pollen and ovule unite to form a seed
gymnosperms vs angiosperms
gymnosperms: no flowers, needle-like, naked seeds that don't have protective fruit, oldest type of seed plant. Angiosperms: flowers, slender leaves, seeds enclosed by food, sources of food, clothing medicine
are plants unicellular or multicellular organisms?
MULTICELLULAR
reproduce from...
seeds
the same between gymnosperms and angiosperms life cycle?
Both do fertilization, seed dispersal, and germination
gymnosperms
a plant that has seeds unprotected by an ovary or fruit.
angiosperms
plants having seeds in a closed ovary
gymnosperms life cycle
pollination, fertilization, seed dispersal, germinate
