Q

What is the red pigment in red blood cells called that allows the cell to carry oxygen?

A

Haemoglobin

17
Q

What is the function of a red blood cell?

A

They transport oxygen around the body

18
Q

How is a leaf cell adapted to carry out its function (job)?

A

It is long and thing which provides a big surface to capture sunlight.

It contains many chloroplasts which carry out photosynthesis

19
Q

What is the function (job) of a nerve cell?

A

To carry electrical impulses around the body

20
Q

What is the function of a root hair cell?

A

To help the plants absorb nutrients and water from the soil

21
Q

How are red blood cells adapted to carry out their function (job)?

A

They contain haemoglobin (red pigment) that joins with oxygen.

They have no nucleus so more room for oxygen.

They have a disklike shape to increase the surface area that oxygen can bind to.

22
Q

Why do root hair cells not have chloroplasts like most plant cells?

A

They are underground so they can’t photosynthesis

23
Q

Where does water go when it enters a cell?

A

It enters the vacuole and makes the cell rigid

24
Q

What is the equation for respiration?

A

Glucose + Oxygen –> Energy + CO2 + H2O

25
Q

How are glucose and oxygen transported around the body?

A

By the blood

26
Q

Which nutrient found in food gives us energy?

A

Glucose

27
Q

How does water move into root hair cells?

A

By diffusion

28
Q

What are the waste products of respiration?

A

Carbon Dioxide and water

29
Q

Where does respiration happen?

A

Inside the mitochondria

30
Q

What do amoebas eat?

A

Bacteria, algae, plant cells

31
Q

Give 2 examples of unicellular organisms

A

Amoeba

Euglena

32
Q

What is the name of the process by which euglena and amoebas reproduce?

A

Binary fission

33
Q

What is the function of the eye spot of a euglena?

A

It detects light

34
Q

How is the euglena adapted to get its energy?

A

It has chloroplasts to do photosynthesis

It has an eye spot to detect light

It has a flagellum to move towards light

35
Q

What is a unicellular organism?

A

An organism that is just made of 1 cell
