Cell Structure
Overview
Every living organism is built from cells, yet most cells are far too small to see with the naked eye. Under a microscope, however, each cell reveals a busy interior packed with specialised structures, each with its own job to do.
In this lesson you will learn to identify and describe the key structures found inside animal and plant cells, explain the function of each organelle, and compare the two cell types. These are core specification points tested across both Paper 1 and Paper 2.
Objectives
- Describe cell structures, including the nucleus, cytoplasm, cell membrane, cell wall, mitochondria, chloroplasts and vacuole
- Describe the functions of the nucleus, cytoplasm, cell membrane, cell wall, mitochondria, chloroplasts and vacuole
- Know the similarities and differences in the structure of plant and animal cells
