4.1.1.2 Animal and Plant Cells

Question 1

What organelle are found in animal cells?

Answer 1

• Cytoplasm
• Nucleus
• Cell membrane
• Ribosome
• Mitochondria

Question 2

What organelle are found in plant cells?

Answer 2

• Nucleus
• Cytoplasm
• Cell membrane
• Mitochondria
• Ribosomes
• Chloroplasts
• A permanent vacuole filled with cell sap

Question 3

What is the cell wall of plant and algae cells made of and what does it do?

Answer 3

• Made of cellulose
• Strengthens the cell

Question 4

Function of Vacuole:

Answer 4

• Contains cell sap
• Helps to support the shape of the cell
• Has a jelly-like texture

Question 5

Function of Nucleus:

Answer 5

• Controls the activities of the cell
• Contains genetic material (including DNA)
• Cells would die without it as it wouldn’t be able to function

Question 6

Function of Ribosomes:

Answer 6

• Site of protein synthesis (where proteins are made)
• Cells have to build protein for the rest of the body and we take it in

Question 7

Function of Cytoplasm:

Answer 7

• Where most of the chemical reactions take place
• Jelly-like texture

Question 8

Function of Cell Membranes:

Answer 8

Controls what passes in and out of the cell

Question 9

Function of Mitochondria:

Answer 9

• Where aerobic respiration takes place to release E
• Aerobic respiration uses oxygen

Question 10

Function of Cell Wall:

Answer 10

• Maintains rigidity of the cell
• Strengthens the cell
• Made of cellulose

Question 11

Function of Chloroplasts:

Answer 11

Where photosynthesis takes place, using a green pigment called chlorophyll which is found in the chloroplast, which is needed to make food for the plant

Question 11

What is cell sap?

Answer 11

The solution inside the vacuole stores materials such as sugars, amino acids, waste products and mineral salts

Question 12

Cell:

Answer 12

• Are the basic units of life
• Are the building blocks of all living organisms
• All living things are made of cells

Question 13

What re the life processes organisms need to stay alive

Answer 13

• Movement: can change its position
• Respiration: release energy from a ‘food’ source, requires oxygen
• Sensitivity: responds to things
• Growth: gets bigger
• Reproduction: can make copies of themselves
• Excretion: get rid of waste materials
  Nutrition: consumes chemical materials as food
