Term Definition
Kingdom Plantae multicellular, eukaryotic, non-motile, contain chlorophyll a + b, cell walls of cellulose, reproduce sexually
Phylum Bryophyta Lack vascular tissue Gametophyte dominant. Live in moist areas. Reproduction dependent on water. (Moss, liverworts)
Phylum Tracheophyta Contain xylem and phloem. Sporophyte dominant. Most common plants.
Subphylum Pteropsida Reproduction dependent on water. (Ferns) [Phylum Tracheophyta]
Subphylum Spermopsida Seed plants [Phylum Tracheophyta]
Class Coniferae seeds in cones. Needle-like leaves. Gymnosperms (Conifers) [Subphylum Spermopsida]
Class Angiospermae Flowering plants. Seeds develop in ovaries. [Subphylum Spermopsida]
Subclass Monocotyledonae Embryo with a single cotyledon, leaves parallel, flower parts in threes (grasses, palm) [Class Angiospermae]
Subclass Dicotyledonae Embryo with two cotyledons. Netted veination. Flower parts in 4 or 5 (Oaks) [Class Angiospermae]
Roots absorb nutrients and water, hold plant upright,
Stems Hold leaves up to sunlight. Transport water and nutrients.
Leaves Perform photosynthesis
Vascular Tissue Transport materials
Xylem transports water and nutrients toward the leaves. Made of tracheids. Long narrow cells with openings at each end
Phloem transports the products of photosynthesis around the plant.
Pollen contains sperm
Seed contains embryo
Gymnosperms “Naked” seeds
Angiosperms Flowering plant Egg is protected in an ovary. Ripe ovary is a fruit
Meristematic Tissue Produces new cells by mitosis. Undifferentiated.
Apical meristem at the tip of a growing stem or root
Cambium allows stems and roots to grow thicker
Epidermal Tissue provides protection
Cork (bark) keeps water out
Epidermis lets water in
Parenchyma Thin walled cells. Store things. Some contain chloroplasts. Some store starch.
Sclerenchyma Thick walled cells. Support the plant
Vessel elements Much larger than tracheids. Transport water.
Sieve tube elements allow the passage of materials
Companion cells control the activity of the sieve tube
