plants

root

absorbs water, and nutrients, anchor plant store food. eg carrot

stem

support leaves and flowers

flower

reproduction

leaves

photosynthesis

green algae

unicellular, colonial plants (eg, seaweed)

bryophytes

non-vascular plabts (eg mosses, liverworts), no vascular tissues, sterms, leaves, roots, or seeds

tracheophytes

vascular plants

polypodiosida

vascular tissue, spores, NOT SEEDS (ferns)

angiosperm

vascular tissue, flowers, seeds (rose, oak)

gymnosperm

vascular tissue, cones, seeds (eg pine, spruce)

meristematic tissues

• an area of actively dividing cells
• apical meristem → in growing tips of stem
• vascular cambium → grow wider

epidermis

one cell thick, cutin in walls prevents water loss and infection

cork

→ short lived cells,

→ protect from mechanical injury

→ prevent water loss and infection (made by cork cambium)

vascular (transport tissues)

xylem → water goes up, food goes down

→ moves up by capillary action (think of water moving on toilet paper)

phloem → takes food down plant
