An individual animal,plant etc. used as an example of its species

Question 14

Question 15

Cell

Answer 15

A microscopic structure containing material enclosed by the basic structural unit of organisms

Question 16

Unicellular Organisms

Answer 16

An unicellular organisms only have one cell

Question 17

Specialised Cell

Answer 17

A cell that has a specialised job to do something

Question 18

Nerve Cell Adaptations

Answer 18

The nerve cell has several adaptations which allows it to carry out its necessary functions.

Question 19

Sperm Cell adaptations

Answer 19

One example: The head contains genetic information and an enzyme to help penetrate the egg cell membrane

Question 20

Egg cell adaptation

Answer 20

A single egg cell is called an ovum. Collectively, eggs and sperm are called gametes or sex cells. When fertilisation occurs, an egg (ovum) and a sperm cell fuse to form a zygote. Eggs and sperm have several important adaptations linked to their structure.

Question 21

Root hair adaptation

Answer 21

Plants absorb water from the soil by osmosis. Root hair cells are updated for this by having a large surface area to speed up osmois

Question 22

Multicellular Organisms

Answer 22

Something which has more than one cell

Question 23

Red blood cell adaptation

Answer 23

They have adaptations that make them suitable for this: they contain haemoglobin - a red protein that combines with oxygen.

Question 24

Diffusion

Answer 24

The spreading of something more widely and quickly

Question 25

The rate of diffusion

Answer 25

How quickly something spreads widely and quickly

Question 26

Binary Fission

Answer 26

A sexual reproduction by a separation of the body into two new bodies
