Explanation:
- The nucleus is the control center of the cell.
- The jelly-like substance inside the cell is called as cytoplasm.
- They are found in both animal and plant cells but are much larger in plant cells.
- In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
- The rest of the air is mostly nitrogen (79%). Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar.
- Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.
