4.1.1.2 Animal and plant cells
| Content | Key opportunities for skills development |
|---|---|
Students should be able to explain how the main sub-cellular structures, including the nucleus, cell membranes, mitochondria, chloroplasts in plant cells and plasmids in bacterial cells are related to their functions. Most animal cells have the following parts:
In addition to the parts found in animal cells, plant cells often have:
Plant and algal cells also have a cell wall made of cellulose, which strengthens the cell. | WS 1.2 Recognise, draw and interpret images of cells. |
Students should be able to use estimations and explain when they should be used to judge the relative size or area of sub-cellular structures. | MS 1d, 3a AT 7 Images of cells in videos, bioviewers, photographs and micrographs can be used as comparison for students own drawings. |
Required practical activity 1: use a light microscope to observe, draw and label a selection of plant and animal cells. A magnification scale must be included.
AT skills covered by this practical activity: biology AT 1 and 7.
This practical activity also provides opportunities to develop WS and MS. Details of all skills are given in Key opportunities for skills development (page 176).
