cell structure and organisation

Structures present only in plant cell

• Cell membrane

• Cell wall

• Chloroplast

• Permanent vacuole

The diagram shows a (an)

• Tissue

• Organ

• Cell

• Organ system

Four Structures present in both plant and animal cell

• Cell wall

• Cell membrane

• Nucleus

• Cytoplasm

• Ribosomes

3 adaptation of the specialised cell

• Cell body - produce impulse in the next neurone

• Long axon fiber for carrying message over long distance

• Myelin sheath on axon - speed up impulse transmission

• Haemoglobin- carry electric impulse

• Dendrites- receive impulse and carry it away from cell body

Two Structures present in red blood cell

• Cell wall

• Cell membrane

• Ribosomes

• Nucleus

• Cytoplasm

4 adaptation of the cell

• Biconcave shape - make it flexible

• Have cell wall- carry oxygen

• Cytoplasm contain haemoglobin - carry oxygen

• No nucleus- more space for haemoglobin

• Small and numerous- increase surface area for carrying oxygen

Which of the following is NOT an adaptation of root hair cell

• Thin cell wall - faster absorption of water and mineral ions

• Vacuole with salts - lower water potential for absorption of water

• Many mitochondria- provide energy for active uptake of mineral ions

• Root hair forms close contact with soil containing water and mineral ions - decrease diffusion distance

• No chloroplast- to carry water quickly

Which process require energy

• Diffusion

• Osmosis

• Active transport

Which process involves movement of water through semi permeable membrane

• Diffusion

• Osmosis

• Active transport

• Air movement

Which cell organelle produces energy by respiration

• Nucleus

• Chloroplast

• Cytoplasm

• Mitochondria
