Master GCSE Biology

MS1:

- A eukaryotic cell has a nucleus and is surrounded by a nuclear membrane (1)

MS2:

- Prokaryotic cells do not have a nucleus/nuclear membrane, while eukaryotic cells do (1)

MS3:

- Controls the cell's activities/directs protein synthesis (1)

- Contains the cell's genetic information (DNA) (1)

MS4:

- Cytoplasm is a jelly-like fluid inside the cell/contains cell organelles (1)

- Cell membrane is a thin, semi-permeable layer surrounding the cell/regulates what enters and leaves the cell (1)

MS5:

- Small, bean-shaped structures (1)

- Contain a double membrane (1)

- Site of cellular respiration/produce energy (ATP) (1)

MS6:

- Contain chlorophyll/green pigment (1)

- Site of photosynthesis/convert light energy into chemical energy (1)

- Produce glucose (1)

MS7:

- DNA replicates/copies itself (1)

- Cell elongates and divides into two identical daughter cells (1)

- No mitosis occurs (1)

MS8:

- Gene expression changes as cells differentiate (1)

- Different genes become active/switched on or off (1)

- Cells develop specific structures and functions (1)

- Forms tissues with specialized cells for specific roles (1)

MS9:

- Magnification increases the apparent size of the image (1)

- Resolution allows the viewer to distinguish between closely spaced objects (1)

- Higher magnification and resolution reveal more detail (1)

MS10:
