Detailed explanation-1: -A prominent difference between a plant and an animal cell is the presence of a cell wall and chloroplasts. Plant cells have chloroplasts and the cell membrane has an outer covering called cell wall. Animal cells lack both chloroplasts and cell walls.
Detailed explanation-2: -The cells of multicellular animals and plants must also differentiate, so that its cells develop features that enable them to fulfil specific roles. Cells that have differentiated have become specialised. Without this specialisation, complex multicellular animals and plants would not exist.
Detailed explanation-3: -As an organism develops, cells differentiate to form different types of cells.-Most types of animal cells differentiate at an early stage.-Many types of plant cells retain the ability to differentiate throught life.
Detailed explanation-4: -Plant cells have a large central vacuole that can occupy up to 90% of the cell’s volume. Animal cells may have many small vacuoles, a lot smaller than the plant cell. Hence statement 3 is correct.
