Animal Cell Interior
Animal cells do not have a rigid wall, so their flexible membrane supports many shapes and movements. Use the viewer to compare the nucleus, mitochondria, and membrane as a coordinated living system.
Structures to inspect
Cell membrane
A flexible boundary that controls what enters and leaves the cell.
Mitochondria
Energy-transforming organelles that help supply ATP for cellular work.
Nucleus
The DNA-containing compartment that coordinates cell activity.
Endoplasmic reticulum
A folded membrane network that helps build and process proteins and lipids.
Glossary
- Membrane
- A thin biological boundary made mostly of lipids and proteins.
- ATP
- A small molecule cells use as a transferable energy source.
FAQ
Do animal cells have chloroplasts?
No. Animal cells obtain energy by consuming molecules rather than capturing sunlight directly.
