cells

Question 1

function and structure of nucleus

Answer 1

nucleur envelope controls what goes in and out of cell
nucleur pore allows large molecules (mRNA) out the nucleus
nucleolus manufactures ribosomes

Question 2

function and structure mitochondria

Answer 2

outer membrane controls what enters and leaves the cell
matrix soultion that contains enzymes for aerobic respiration
small ribosomes production of protein
inner membrane folded to make cristae which largens the surface area for more ATP

Question 3

FUNCTION AND STRUCTURE OF LYSOSOME

Answer 3

lysosomes are vesicles formed by golgi apparatus containing enzymes ( isolating themselevs as they are harmful)

-digest worn out organelles
-hydrolyse pathogens
break down dead cells

Question 4

rough endoplasmatic recticulum

Answer 4

-ribosomes are present
-transports and synthesis protiens

Question 5

smooth endoplasmatic reticulum

Answer 5

-lacks ribosomes
-transports, synthisis and stores lipid and carbohydrate

Question 6

golgi apparatus

Answer 6

recieves protiens and lipids from ER, also protiens are labelled which allows them to go to the correct location
-adds carbohydrates to protien to form glycoprotien
-produce secutory enzymes
-secretes carbohydrates
forms lysosomes
-transports,modify, stores lipid

Question 7

chloroplast structure and function

Answer 7

chloroplast envelope controls what enters and leaves the cells
grana stacks of thylokoids
thylokoid contains chlorophyll and protiend needed for light deoendent stage of phtosyntheises
