(a) (i) Forms in which living cells exist

Single/free-living
Colony/colonial
Filamentous/filament
Part of a living organism.

(ii) Example

Single/free-living -Amoeba/Chlamydomonas/Paramecium/Euglena
Colony/colonial -Eudorina/Pandorinallolvox/Sponges
Filamentous/filament - Spirogyra/Chladophora/Ulothrix/Zygnema/Oedogonium
Part of living organism - cheek cell/onion cell/epidermal cell/parenchyma cell.

(b) Diagram of a typical plant cell
(c) (i) Differences between a plant cell and an animal cell

plant cell	Animal
Has cellulose cell wall / rigid	Lacks cellulose cell wall
Has one large central vocoule	has numerous/vocoule
has chloroplast	lacks chloroplast
Contains starch granules in its cytoplasm	contains glycogen granules in it cytoplasm
Usually larger in size	Usually smaller in size
Does not have lysosome	has lysosome
Does not have centrioles / centrosome	Has centrioles / centrosome
Has a regular / defined cell shape	has an irregular / indefinite cell shape
cytoplasm less dense	cytoplasm more dense
stores lipid as oil	stores lipid as fat

(ii) Similarities in plant cell and animal cell;
They both have cytoplasm; nucleus; vacuole; mitochondrion; Golgi body; (smooth/rough) endoplasmic reticulum; cell membrane/plasma membrane; ribosomes
