Plant Cell Architecture
Plant cells combine a protective cell wall with internal compartments that harvest light, store water, and coordinate growth. Rotate the model and isolate the chloroplast, vacuole, nucleus, and membrane to see how structure supports function.
Structures to inspect
Cell wall
A firm outer layer that gives the plant cell shape and mechanical support.
Chloroplast
A light-harvesting organelle where photosynthesis converts light energy into chemical energy.
Central vacuole
A large fluid-filled compartment that stores water and helps maintain pressure.
Nucleus
The control center that stores DNA and coordinates gene expression.
Glossary
- Organelle
- A specialized structure inside a cell with a specific job.
- Photosynthesis
- The process plants use to turn light, carbon dioxide, and water into sugars.
FAQ
Why do plant cells look boxier than animal cells?
The cell wall is stiff, so it constrains the cell into a more regular shape than a flexible animal cell membrane.
