Across
- 2. Organelles that contains the green pigment, chlorophyll, which absorbs light energy for photosynthesis. Contains the enzymes needed for photosynthesis.
- 4. A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
- 7. Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.
- 9. Tiny structures where protein synthesis occurs.
- 11. Contains genetic material, including DNA, which controls the cell’s activities.
- 12. The movement of water from a high water concentration to a low water concentration.
- 13. The passive movement of gases and liquid molecules from high to low concentrations.
- 14. A gas needed for photosynthesis.
- 15. The process of water movement in a plant
Down
- 1. Made from cellulose fibres and strengthens the cell and supports the plant.
- 3. A hollow tube within a cell through which water moves.
- 5. The process of sucrose movement in a plant.
- 6. Filled with cell sap to help keep the cell turgid.
- 8. Organelles that contain the enzymes for respiration, and where most energy is released in respiration.
- 10. A gas needed for aerobic respiration.
