B1 Cell Biology

Question 1

What are all living things made up of?

Answer 1

Cells

Question 2

What are the two types of cells?

Answer 2

Prokaryotic or Eukaryotic

Question 3

Describe Eukaryotic cells

Answer 3

Eukaryotic cells are complex and include animal and plant cells.

Question 4

Describe Prokaryotic cells

Answer 4

Prokaryotic cells are smaller and simpler e.g. Bacteria

Question 5

What is a Eukaryotes?

Answer 5

Eukaryotes are organisms that are made up of Eukaryotic cells

Question 6

What is a Prokaryote?

Answer 6

A Prokaryote is a prokaryotic cell (its a single-celled organism)

Question 7

what are parts of the cell called?

Answer 7

Sub-cellular structures

Question 8

Explain the Nucleus in the Animal Cell

Answer 8

The Nucleus contains genetic material that controls the activities of the cell

Question 9

Explain the Cytoplasm in the Animal cell

Answer 9

The cytoplasm is a gel like substance where most of the chemical reactions happen, it contains enzymes that control these chemical reactions.

Question 10

Explain the Cell membrane in the Animal cell

Answer 10

The cell membrane holds the cell together and controls what goes in and out.

Question 11

Explain the Mitochondria in the Animal cell

Answer 11

the Mitochondria is where most of the reactions for aerobic respiration take place. respiration transfers energy that the cell needs to work.

Question 12

Explain Ribosomes in the Animal cell

Answer 12

Ribosomes are where proteins are made in the cell

Question 13

Do plant cells have the same Subcellular structures as Animal cells

Answer 13

Plant cells usually have all the bits that animal cells and extra things that animal cells don’t have

Question 14

Name 5 things in plant cells that are also in animal cells

Answer 14

• Nucleus
• Cytoplasm
• Cell membrane
• Mitochondria
• Ribosomes

Question 15

Explain Rigid cell wall in the plant cell

Answer 15

The Rigid cell wall is made of cellulose, it supports the cell and strengthens it.

Question 16

Explain the Permanent vacuole in the plant cell

Answer 16

The permanent vacuole contains cell sap, a weak solution of sugar and salts

Question 17

Explain Chloroplasts in the plant cell

Answer 17

Chloroplasts are where photosynthesis occurs, which makes food for the plant. They contain a green substance called Chlorophyll which absorbs the light needed for the photosynthesis

Question 18

what type of cell is a Bacteria cell

Answer 18

Bacteria cells are Prokaryotes

Question 19

What do bacteria cells have in common with animal and plant cells?

Answer 19

Bacteria cells have a cytoplasm, cell membrane and a cell wall

Question 20

Explain the nucleus in the bacterial cell

Answer 20

Bacterial cells don’t have a “true” nucleus, instead they have a single circular strand of DNA that floats freely in the cytoplasm.

Question 21

Explain the Plasmids in the Bacterial cell

Answer 21

The plasmids are one or more small rings of DNA
