1. Central Vacuole the organelles is found in the plant cells, but not in the animal cells
2. Adjacent plant cell are together by middle lamella
3. Plant cell communicate with each other through Plasmodesmata
4. The toxic substance used by plant for defense are stored in the Vacuole
5. Anthocyanin pigments are stored in the Vacuole
6. Hydrogen peroxide detoxified in the Peroxisome
7. The pathways of newly synthesized protein is Ribosome – rough ER - transition vesicle – Golgi apparatus – secretory vesicle
8. Pumps is needed for an active transport
9. Potato slice when place in pure water for several hours, will become very stiff because
water has passed into the potato cells to produce turger
