Across
- 4. Contains genetic material, including DNA, which controls the cell’s activities.
- 5. Rate of diffusion is higher at a higher _ because the particles will have more kinetic energy.
- 7. Organelles that contain the enzymes for respiration, and where most energy is released in respiration.
- 9. Its structure is permeable to some substances but not to others. It therefore controls the movement of substances in and out of the cell.(2 words, 3 Letters/8 Letters)
Down
- 1. The larger the _, the faster the rate of diffusion because more particles can pass through the membrane at the same time.(2 words, 7 Letters/4 Letters)
- 2. A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen.
- 3. Osmosis is the movement of water molecules from an area of high _ to an area of low _.
- 6. Tiny structures where protein synthesis occurs.
- 8. A partially permeable barrier that surrounds the cell, controlling the movement of substances in and out. (2 words, 4 Letters/ 4 Letters)
