Lets things in and out of the cell

Question 7

Chlorophyll

Answer 7

Takes in sunlight for photosynthesis

Question 8

Eukaryotic cell

Answer 8

They are animal and plant cells

Question 9

Prokaryotic cells

Answer 9

Bacteria is an example of it

Question 10

Nerve cells

Answer 10

They are specialised to carry electrical nerves through the body

Question 11

Muscle Cells

Answer 11

They are cells that can contract or relax

Question 12

Sperm Cells

Answer 12

Sperm cells are released a long way from the egg to be fertilised

Question 13

Xylem cells

Answer 13

It transports water and minireals from the roots throughout the plant

Question 14

Diffusion

Answer 14

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Question 15

Osmosis

Answer 15

Osmosis is the diffusion of water from a dilute solution to be a concentrated solution.

Question 16

Factors that effect diffusion

Answer 16

1: Increase the concentration gradient(a bigger difference between the two areas)
2: Temperature the higher the tempreture the faster the diffusion will be.
3: The surface area of exchange surface
4: Shorter diffusion distance

Question 17

Why is diffusion important

Answer 17

Diffusion is important because it delivers nutrients and gets rid of waste products

Question 18

Nerve cells

Answer 18

They are specialised to carry electrical nerves through the body

Question 19

Muscle Cells

Answer 19

They are cells that can contract or relax

Question 20

Sperm Cells

Answer 20

Sperm cells are released a long way from the egg to be fertilised

Question 21

Xylem cells

Answer 21

It transports water and minireals from the roots throughout the plant

Question 22

Osmosis

Answer 22

From low to high concentration

Question 23

Active transport

Answer 23

Active transport is the process by which dissolved molecules move across a cell membrane from low to high

Question 24

Active transport

Answer 24

Up against the gradient
