AQA GCSE Biology · Topic 1
57 cards on Cell Biology, every one written against a numbered point in section 4.1 of the AQA Biology spec. Here’s what the topic covers, and 4 cards to try.
Answer each one in your head, then check. In the app, how well you knew it decides when you see it again.
4.1.1.1 · Eukaryotes & Prokaryotes
Eukaryotic cells have a cell membrane, cytoplasm and genetic material enclosed in a nucleus (e.g. plant and animal cells). Prokaryotic cells are bacterial cells: much smaller, with no nucleus.
4.1.1.3–4.1.1.4 · Cell Specialisation & Differentiation
A tail to swim, lots of mitochondria to release energy for swimming, and an acrosome in the head containing enzymes to digest through the egg cell membrane.
4.1.2.1–4.1.2.2 · Chromosomes & Mitosis
Chromosomes are made of DNA molecules, each carrying a large number of genes, found in the nucleus. Human body cells have 23 pairs (46 in total).
4.1.3.1 · Diffusion
The net movement of particles from an area of higher concentration to an area of lower concentration. It is passive: it needs no energy from respiration.
Every part of section 4.1 of the AQA spec, and how many cards cover it. Cards only on the separate Biology GCSE are hidden for Combined Science.
The method, the variables and a worked example for each.
