- CELLS AND CELL STRUCTURE
- Most human and animal cells have the following parts:
- A nucleus, which controls the activities of the cell
- Cytoplasm- in which most of the chemical reactions take place
- A cell membrane- which controls the passage of substances into and out of the cell
- Mitochondria- which is where most energy is released in respiration
- Ribosomes- which is where protein synthesis occurs
- Mitochondria- which is where most energy is released in respiration
- A cell membrane- which controls the passage of substances into and out of the cell
- Cytoplasm- in which most of the chemical reactions take place
- A nucleus, which controls the activities of the cell
- Plant and algal cells also have a cell wall made of cellulose, which strengthens the cell.
- Chloroplasts- which absorb light energy to make food
- A permanent vacuole filled with cell sap
- Chloroplasts- which absorb light energy to make food
- A bacterial cell consists of cytoplasm and a membrane surrounded by a cell wall; the genes are not in a distinct nucleus
- Yeast is a single-celled organism. Yeast cells have a nucleus, cytoplasm and a membrane surrounded by a cell wall
- Cells may be specialised to carry out a particular function
- Most human and animal cells have the following parts:
- Chloroplasts- which absorb light energy to make food
- A permanent vacuole filled with cell sap
