Question 1 Report
(a) (i) List three forms in which living cells exist
(ii) Give one example each of the forms listed in 1 (a)(a)
(b) Make a diagram, 6 cm — 10 cm long, of a typical plant cell and label fully
(c) (i) In a tabular form, state three differences between a plant cell and animal cell.
(ii) State three similarities between a plant cell and animal cell.
Answer Details
(a)(i) Three forms in which living cells exist
- As single, free-living (unicellular) organisms.
- As a colony of cells.
- As part of a many-celled (multicellular) organism (in tissues).
(a)(ii) One example each
- Unicellular (single cell): Amoeba (or Euglena, Paramecium).
- Colony: Volvox (or Spirogyra as a filament).
- Multicellular: a human being (or a maize plant).
(b) A diagram 6 to 10 cm long of a typical plant cell is required, labelling: cell wall, cell membrane, cytoplasm, nucleus, large central vacuole, chloroplast and (if shown) mitochondria.
(c)(i) Three differences between a plant cell and an animal cell
| Plant cell | Animal cell |
|---|---|
| Has a cellulose cell wall outside the membrane | Has no cell wall, only a cell membrane |
| Has chloroplasts (in green parts) | Has no chloroplasts |
| Has one large central vacuole | Vacuoles are small, temporary or absent |
(c)(ii) Three similarities between a plant cell and an animal cell
- Both have a cell membrane.
- Both have cytoplasm.
- Both have a nucleus (and mitochondria).
