They usually have all the bits that animal cells have, plus...
1. Rigid cell wall - made of cellulose. It supports and strengthens the cell.
2. Permanent vacuole - contains cell sap, a weak solution of sugar and salts.
3. Chloroplasts - where photosynthesis occurs, which makes food for the plant. They contain chlorophyll.
- Chloroplasts are surrounded by a double membrane, and also have membranes inside called thylakoid membranes. These membranes are stacked up in the chloroplast to form grana.
- Grana are linked together by lamellae - thin, flat pieces of thylakoid membrane
- Some parts of photosynthesis happen in the grana, and other parts in the stroma (a thick fluid found in chloroplasts).
