cell structure

Question 1

what is the function of the cell surface membrane and what type of cell are they found

Answer 1

to control what substances enter and exit the cell and it’s the site of cell signalling and recognition for prokaryotic and eukaryotic cells

Question 2

what is the function of the nucleus and what type of cell are they found in

Answer 2

stores dna and is only found in a eukaryotic cell

Question 3

function of mitochondria and type of cell they are found in

Answer 3

carry out aerobic respiration to produce ATP and are found in eukaryotes

Question 4

function of lysosomes and type of cell they are found in

Answer 4

membrane bound organelles full of hydrolytic enzymes used to break down pathogens, old organelles and nutrients. membrane bound so enzymes don’t digest the cell and are found in eukaryotes

Question 5

function of ribosomes and what type of cell they are found in

Answer 5

site of protein synthesis found in in eukaryotes (80s) and prokaryotes (70s)

Question 6

function of rough endoplasmic reticulum and what type of cell they are found in

Answer 6

provide a large surface area from their many flattened membrane sheets called cisternae with many ribosomes embedded so there’s a large site for protein synthesis. it is an extension of the nuclear envelope. found in eukaryotes

Question 7

function of smooth endoplasmic reticulum and cell type they are found in

Answer 7

extension of rer it synthesises, stores and transports lipids steroids and carbohydrates. found in eukaryotes

Question 8

function of golgi apparatus and cell type they are found in

Answer 8

modifies proteins sent from rer
sorts and packages proteins into vesicles for transport in the cell or out of the cell via exocytosis. made up of flattened sacks called cisternae found in eukaryotes

Question 9

function of chloroplast and what type of cells they are found in

Answer 9

membrane bound site of photosynthesis
contain lots of chlorophyll for absorbing sunlight
found in plants and algae

Question 10

function of permanent vacuole and what cell type it’s found in

Answer 10

maintains cell turgidity with water pressure and acts as a energy store found in plant cells

Question 11

cell wall function and type of cell it’s found in

Answer 11

provides structural support for the cell and is found in plants algae and fungi
