2018 AQA GCSE Combined Science Specification
Topic - Cells

Part of specification covered:

Plant and animal cells (eukaryotic cells) have a cell membrane, cytoplasm and genetic material enclosed in a nucleus.

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:
• A nucleus • cytoplasm • a cell membrane • mitochondria • ribosomes.
In addition to the parts found in animal cells, plant cells often have:
• Chloroplasts • a permanent vacuole filled with cell sap.
Plant and algal cells also have a cell wall made of cellulose, which strengthens the cell.

Bacterial cells (prokaryotic cells) are much smaller in comparison. They have cytoplasm and a cell membrane surrounded by a cell wall. The genetic material is not enclosed in a nucleus. It is a single DNA loop and there may be one or more small rings of DNA called plasmids.

Thanks - this is a really nicely planned out scheme. Like the help for comparative writing and links to the homework.
