c) State the function of the following cell organelles. Cytoplasm: The site where most cellular activities and metabolic reactions occur, and it holds organelles in place. Smooth endoplasmic reticulum: Synthesizes lipids, phospholipids, and steroids, and detoxifies drugs and poisons. 4. a) State FOUR differences between plant and animal cells. i) Plant cells have a cell wall*; animal cells do not. ii) Plant cells have chloroplasts*; animal cells do not. iii) Plant cells have a large, permanent central vacuole*; animal cells have small, temporary, or no vacuoles. iv) Plant cells typically have a fixed, rigid shape*; animal cells have an irregular, flexible shape. c) Identify the specialized animal or plant cell that performs each of the following functions. i) Transports oxygen in the body: Red blood cell* ii) Absorbs water and mineral salts from the soil: Root hair cell* iii) Transmits electrical impulses in the body: Nerve cell (Neuron)* iv) Carries out photosynthesis efficiently: Palisade cell* v) Controls opening and closing of stomata: Guard cell* vi) Enables movement by contraction: Muscle cell* b) State the ways in which the following cells are adapted to their functions. i) Root hair cell: It has a long, thin extension* (root hair) to increase the surface area for efficient absorption of water and mineral salts. ii) Red blood cell: It has a biconcave disc shape* to increase the surface area to volume ratio for faster oxygen diffusion and lacks a nucleus to allow more space for hemoglobin. 5. a) Name TWO classes of chemicals of life found in cells. i) Carbohydrates* ii) Proteins* Send me the next one 📸
