B1 : Animal and Plant cells

Question 1

Cell membrane

Answer 1

Controls what goes in and out of the cell

Question 2

Ribosomes

Answer 2

The site of protein synthesis

Question 3

Nucleus

Answer 3

Contains genetic material of the cell and controls the cell

Question 4

Cytoplasm

Answer 4

Where chemical reactions take place

Question 5

Mitochondria

Answer 5

Energy released from respiration

Question 6

Chloroplast

Answer 6

The site of photosynthesis

Question 7

Permanent Vacuole

Answer 7

Gives the cell structure and a store of sap

Question 8

Cell wall

Answer 8

Gives the plant structure and support

Question 9

Define eukaryotic

Answer 9

Cells such as animal and plant cells that contain genetic material in the nucleus

Question 10

List the organelles found in an animal cell

Answer 10

Nucleus, Cell membrane, Ribosomes, Mitochondria and Cytoplasm

Question 11

What is the function of the nucleus

Answer 11

To store genetic material

Question 12

What is the function of the mitochondria

Answer 12

The site of aerobic respiration

Question 13

What three cell structures are found only in plant cells and not in animal cells?

Answer 13

Cell wall, chloroplast, permanent vacuole

Question 14

What structure is responsible for making proteins

Answer 14

Ribosomes

Question 15

What is the role of chloroplasts

Answer 15

The site of photosynthesis, contains chlorophyll

Question 16

Salivary cells produce amylase, which is a type of protein, what type of cell structure will they have a lot of?

Answer 16

Ribosomes

Question 17

Why are muscle cells likely to have large number of mitochondria?

Answer 17

Muscles cells require more mitochondria because they this id where aerobic respiration occurs and transfers energy through the use of ATP by the muscles.

Question 18

The root hair cell is a plant cell, but it has no chloroplasts why is it not considered an animal cell?

Answer 18

It contains no chloroplasts because it is underground and so receives no sun and so doesn’t require chloroplasts. It does contain all of the other factors that are present in plant cells.

Question 19

Suggest why the nucleus and mitochondria are so important in all cells (4)

Answer 19

.The nucleus is important in all cells because the nucleus allows for the production of all proteins. It contains all of the genetic code that the body is created from
.Mitochondria is needed to allow the energy for a wide range of biological processes such as muscle contraction and movement

Question 20

Compare a plant and animal cell (4)

Answer 20

Different shapes.
Different organelles, both have nucleus, cytoplasm, mitochondria, ribosomes and cell membranes. Both are responsible for protein synthesis for growth and repair.
