Human Bio Unit 1 - Cell Structure

Question 0

Lysosomes

Answer 0

Spherical

Acidic vesicles

Aid enzymatic digestion

Question 1

Cell membrane

Answer 1

Phospholipid bilayer

Partially permeable

Question 2

Smooth endoplasmic reticulum

Answer 2

Lipid synthesis

Question 3

Rough endoplasmic reticulum

Answer 3

Protein synthesis

Question 4

Endoplasmic reticulum

Answer 4

Closely linked with transport activities with the Golgi body

Folded over on itself

Made up of the smooth and rough endoplasmic reticulum

Question 5

Nucleus

Answer 5

Surrounded by nucleic envelope

Controls the cell

Stores DNA

Question 6

Golgi body

Answer 6

Receives proteins from the endoplasmic reticulum

Packages proteins in vesicles and sends them off to other parts of the cell

Question 7

Mitochondria

Answer 7

Produces ATP through respiration

Lots of mitochondria is a sign that the cell is active

Question 8

Organelles

Answer 8

Specialised sub units inside the cell

Question 9

Fluid mosaic

Answer 9

Looks like a mosaic because of all the phosphate heads and carrier proteins and extrinsic proteins present

Fluid because they move about

Question 10

Make up of phospholipids

Answer 10

Hydrophobic tail

Hydrophilic phosphate head

Question 11

Or

Answer 11

Nucleus releases RNA

Goes to rough endoplasmic recticulum where proteins are made

Go to the Golgi body, where proteins are modified

Transported by a vesicle to cell membrane
