A) Identify FOUR specialized plant cells and describe their functions. b) Identify FOUR specialized animal cells and describe their functions.

here are the answers for question 7:

a) Identify FOUR specialized plant cells and describe their functions.

1. Root hair cell: Absorbs water and mineral salts from the soil.
2. Xylem vessel element: Transports water and dissolved minerals from the roots to the rest of the plant.
3. Phloem sieve tube element: Transports sugars (food) produced during photosynthesis from the leaves to other parts of the plant.
4. Guard cell: Regulates the opening and closing of stomata, controlling gas exchange and transpiration.

b) Identify FOUR specialized animal cells and describe their functions.

1. Red blood cell (Erythrocyte): Transports oxygen from the lungs to the body tissues and carries carbon dioxide back to the lungs.
2. Nerve cell (Neuron): Transmits electrical signals (nerve impulses) throughout the body to coordinate actions and sensations.
3. Muscle cell (Myocyte): Contracts to produce movement in the body.
4. Sperm cell: Carries male genetic material to fertilize an egg cell.
