Plant organ systems

plant organs

flower, leaf, stem, roots

plant tissues

dermal (protect), ground (photosyntheisis and storage), vasuclar (transport water and sugar)

Cubticle (leaf)

waxy layer and waterproof (not a tissue)

upper and lower epidermis (leaf)

upper makes wax while lower protects leaf (dermal tissue)

mesophyl (leaf)

photosynthesis has cloraplast (ground tissue)

vascular tisssue (leaf, root, and stem)

transport water and sugar (xylem +pholem)

stomata (leaf)

pores that let co2 in

Guard cells (leaf)

open and closes stomata (dermal)

leaf

• cubticle

• upper and lower epidermis

• mesophyl

• vascular tissues

• stomata

• guard cells

stem

• epidermis

• vascular tissues

• cortex

epidermis (stem and root)

protects (dermal) somtimes has root hairs if in root

cortex (stem and root)

storage and has large vacuole (ground)

how does pollination occur?

pollen gets transferred to the stigma using wind and insects/bird and which forms a pollen tube and gets transferred to the ovule

what happens after pollination

the ovary develops into fruit and seeds

why does the ovary turn into fruit

• to disprese the seed far away from the parent plant

• which will decrease competition for nutrients, water, and sun

methods of seed dispersal

• wind

• water

• other organisms (animals)

germination

happens after seed dispersal. When seeds develop into plants. Needs correct tempature, water, and oxygen

root

• epidermis

• vascular tissue

• cortex
