Animal cell structures and their functions

I can identify common structures of animal cells and describe what these structures do.

Lesson details

Key learning points

  1. Cells have a 3D shape (not 2D as they often appear in textbooks).
  2. Common structures of animal cells can be shown in diagrams.
  3. These structures include the cytoplasm, cell membrane, nucleus and mitochondria.
  4. Each structure in an animal cell has a specific function.
  5. Cells can be represented using 2D and 3D scientific models.

Common misconception

Cells are 2D (as they are often depicted in diagrams).

The lesson explores the 3D structure of cells, and the use of both 2D and 3D scientific models of animal cells.

Keywords

  • Cell membrane - The cell membrane surrounds the cell and controls what substances enter and leave the cell.

  • Cytoplasm - The cytoplasm is the jelly-like substance inside a cell where the chemical reactions of the cell take place.

  • Nucleus - The nucleus contains DNA, which stores information that controls the activities of the cell.

  • Mitochondria - Mitochondria use food and oxygen as fuel to provide energy for the cell in a process called cellular respiration.

  • Model - Scientists use models as simpler representations of complex things and ideas.

Asking pupils to build their own models of animals cells, and then peer evaluate them, can help make cells seem less abstract, develop awareness of the 3D nature of cells, and increase engagement.
