Lesson Details
Key learning points
- The animal cell model describes the common structures of animal cells.
- These structures include the cytoplasm, cell membrane, nucleus and mitochondria. Each structure has a specific function.
- Specialised cells in animals have shapes, sizes and structures that are adapted for the jobs the cells do.
- Examples of specialised animal cells include blood cells and nerve cells.
Common misconception
All animal cells are the same as the model animal cell. Energy is created during respiration.
The model animal cell simplifies the complex structure of animal cells. There are specialised animal cells that have different shapes and sub-cellular structures to help them carry out a specific function. Energy is transferred through respiration.
Keywords
Cytoplasm - A jelly-like substance containing dissolved nutrients and salts where many chemical reactions happen.
Cell membrane - A partially permeable structure that surrounds the cell; it controls the movement of substances into and out of the cell.
Nucleus - A sub-cellular structure that contains genetic material, which controls cellular activities.
Dna - A molecule found in the nucleus of cells and contains the genetic code for making proteins.
Mitochondria - Sub-cellular structures that contain the enzymes for respiration, and is where most energy is released in respiration.
