plant cells parts and there defiontions

Question 1

guard

Answer 1

this is an arragement of two cells around each stoma in the lower leaf. the cells change shape to open and close the stoma

Question 2

epidermiss

Answer 2

the protective layer of the cells in the upper and lower regions of the leaf.they are transparent to allow light to pass to the cell inside

Question 3

chloroplasts

Answer 3

filled with chlorophyl and absorbs light energy from the sun to make glucose for the plant in a process known as photosythesis

Question 4

nucleus

Answer 4

controlls the activity of the cell and stores the dna as chromosomes

Question 5

ribosomes

Answer 5

read code from the nucleas and make proteins for the cell

Question 6

vacuole

Answer 6

contains cell sap, which prevents the cell from bursting with water intake

Question 7

cell wall

Answer 7

streanthens the outside of the plant cell and made of material known as cellulose

Question 8

cytoplasm

Answer 8

reactions controlled by enzymes happen here

Question 9

mitrochondria

Answer 9

makes and releasses energy from the cell using a process called respiration

Question 10

cell membrane

Answer 10

controls what enters and leaves the cell

Question 11

waxy cuticle

Answer 11

a layer of wax that coats the surface of the leaf.prevents water loss by evaporation and is transparent to allow light to pass to cells inside

Question 12

stoma

Answer 12

tiny hole/holes in the lower surface of the leaf that allow gas exchange between the internal and external leaf structure

Question 13

palisade

Answer 13

this is a layer of closely packed cells containg high proportion of chloroplasts. this is the site of photo-synthesis

Question 14

spongy mesophyll

Answer 14

this is a layer of cerlls that contains large air spaces.these spaces allow for diffusion in gas, between stomata and palisides cells
