Cells Booklet 2 - First Form

Question 1

If an organism only has one cell what is it called

Answer 1

A Uni-cellular organism

Question 2

If an cell organism has a cell membrane, cytoplasm, chloroplast & a nucleus; is it an animal or plant cell and why.

Answer 2

It’s an animal cell because it doesn’t have a cell wall or a vacuole.

Question 3

What was the above cell called

Answer 3

A Euglena

Question 4

What was the euglena’s extra part that hasn’t been mentioned.

Answer 4

The Whip Like Flagellum

Question 5

What is a flagellum used for

Answer 5

For Movement

Question 6

How do substances move in and out of cells?

Answer 6

Diffusion

Question 7

What substances move into cells?

Answer 7

Oxygen & Glucose needed by the cell.

Question 8

What substances move out of cells?

Answer 8

Waste Products such as Carbon Dioxide.

Question 9

Name 3 examples of diffusion in real life

Answer 9

-> Teabags in hot water
-> Potassium Permanganate in water
-> Air Freshener

Question 10

What is the definition of diffusion?

Answer 10

The movement of particles from a high concentration to a low concentration until equilibrium(everything equal)

Question 11

Finish this sentence: The bigger the difference in concentration…

Answer 11

the faster the rate of diffusion will be.

Question 12

If you have a petri dish of agar(universal indicator) and make two holes and put acid in one and alkali in the other. What does it look like and why.

Answer 12

It turns red on the side where the acid was put in, green on the side where the alkali was put in & a yellow stripe down the middle where the meet and have neutralised each other.

Question 13

What is the function of a palisade plant cell?

Answer 13

To carry out photosynthesis using energy from sunlight.

Question 14

What is the function of a nerve cell

Answer 14

To transmit electrical impulses around the body to co-ordinate responses

Question 15

What is the function of a ciliated epithelial cell

Answer 15

To move microorganisms and dust away from the lungs

Question 16

What is the function of an egg cell

Answer 16

To be fertilised by the sperm cell

Question 17

What is the function of a root hair cell

Answer 17

To absorb water and minerals from soil

Question 18

What is the function of a sperm cell

Answer 18

To fertilise an egg cell and make a baby

Question 19

What is the function of a red blood cell

Answer 19

To carry oxygen around the body

Question 20

Name the adaptations of a root hair cell

Answer 20

-> Large Surface Area
-> No Chloroplasts

Question 21

What are the adaptations of a sperm cell

Answer 21

-> Long tail to swim
-> Lots of mitochondria to provide energy
-> Chemicals in the head to get into the egg cell

Question 22

What are the adaptations of a red blood cell

Answer 22

-> Biconcave shape to easily move through blood vessels
-> Large surface area for diffusion
-> No nucleus
-> Contains haemoglobin

Question 23

What are the adaptations of a palisade cell

Answer 23

-> Tall and thin
-> Lots of chloroplasts for photosynthesis

Question 24

What are the adaptations of a nerve cell

Answer 24

-> Long thin axon
-> Branching dendrites at either end
-> Can carry electrical impulses.

Question 25

What are adaptations of a ciliated epithelial cell

Answer 25

-> Tiny hairs called cilia to sweep particles away
-> Lots of mitochondria to provide energy

Question 26

What are the adaptations of an egg cell

Answer 26

-> Cytoplasm contains nutrients for developing the embryo
-> Membrane changes after fertilisation to stop any more sperm getting in
