The table shows the main functions of red blood cells and root hair cells.

Which row is correct?

• A

• B

• C

• D

Name structure of a plant cell which controls the passage of substances into and out of the cell.

• Cell membrane

• Cell wall

• Chloroplast

• Cytoplasm

What may be found in both animal and plant cells

• Cellulose cell wall

• Chloroplast

• Large vacuoles

• Nucleus

Name red pigment that is present in red blood cells.

• Haemoglobin

• Chlorophyll

• Chloroplast

• Vacuole

What is the function of red blood cell?

• Absorb water and minerals

• Absorb oxygen

• Transport oxygen

• Transport water and minerals

Which description applies to red blood cell?

• A

• B

• C

• D

Red blood cells have a relatively large surface area.

How does this help the red blood cell carry out its function?

• It can absorb the oxygen more quickly

• It can carry more oxygen

• It can maintain a concentration gradient

• It can pass through small blood vessel

Which sentence about red blood cells is correct?

• They transport carbon dioxide and contain chlorophyll

• They transport carbon dioxide and contain haemoglobin

• They transport oxygen and contain chlorophyll

• They transport oxygen and contain haemoglobin

Which of the following structure is present in animal cell but not in red blood cell.

• Nucleus

• Cell membrane

• Cytoplasm

• Cell wall

Why red blood cell does not contain nucleus?

• Cytoplasm can contain more chlorophyll so more carbon dioxide can be transported

• Cytoplasm can contain more haemoglobin so more oxygen can be transported

• Chloroplast can contain more chlorophyll so more carbon dioxide can be transported

• Chloroplast can contain more haemoglobin so more oxygen can be transported
