Check out the BBC Bitesize guide to the cell cycle for videos, text explainers, infographics and more Combined Science GCSE revision resources. The other type of cell division is called meiosis.
This had never happened before. There is a remarkable story behind these cells; it's more than half a century old, but still relevant and current. Dr Maninder Ahluwalia, senior lecturer in ...
Many cells in multicellular organisms are specialised. They have specific roles in the organism of which they are part. Their structure is adapted to their function. They are often grouped ...
Organisms are made up of cells. Most organisms are multicellular and have cells that are specialised to do a particular job. Microscopes are needed to study cells in detail. In this video ...
Bacteria are amongst the simplest of organisms - they are made of single cells. Their cell structure is simpler than the cells of animals, plants and fungi. Size Most are 5 μm - 100 μm.
Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

This is called photosynthesis. The basic structure of a plant cell is shown below. Photosynthesis relies on many structures in the cell all working together, each playing its role. The diagram ...

Most animal cells range in size from 10 - 50 μm, and plant cells from 10 - 100 μm. The human eye can see objects as small as 50 μm. We require a microscope to see cells in further detail.
