Plant Structure and tissues

difference between animal and plant cells

mostly the same but in plants the vacuole is big and there is a cell wall and chloroplasts

what is the cell wall made of

cellulose

plasmodesmata

holes in the membrane and wall to move things between cells

what are the three tissue systems

Dermal, vascular, ground

Function of Dermal Tissue

forms outer covering of a plant (epidermis) and usually consists of a single cell layer

Function of Vascular tissue

The plumbing; transports water and nutrients from the site of production/intake to where it is needed rg

function of ground tissue

forms most of the planet body, it functions in storage support and photoynthesis

what types of cells are dermal tissue made of

stomata (guard cells), trichomes, root hairs, epidermal cells

function of stomata

dermal tissue that is an opening into a leaf of a plant where can exchange can occur

function of trichomes

to protect leaf/ plant from herbivores

The types of Vascular tissue

xylem, phloem

xylem

transports water and mineral ions from the roots to the rest of the plants

phloem

transports carbohydrates (sugars) from sites of production to sites of use/storage

types of cells that make up xylem

treachery elements, vessel elements

both dead when mature

Treachery elements are longer and thinner

vessel elements are more tube like

what is phloem made of

made of sieve tube elements- looks like pasta strainer, holes in cells

they are alive the mature

ends of walls have plasmodesmata (pores
