Master GCSE Biology

MS1: The jelly-like substance inside a cell that contains organelles (1)

MS2:

- Selectively permeable/controls what enters and leaves the cell (1)

- Controls the concentration of substances/prevents loss of essential materials (1)

MS3: Eukaryote (1)

MS4:

- Both are membrane-bound vesicles (1)

- Vacuoles store non-toxic substances (1)

- Lysosomes store hydrolytic enzymes for digestion and destroy pathogens (1)

MS5: Protein synthesis (1)

MS6:

- Replication of chromosome (1)

- Chromosome attachment to the cell membrane and elongation of cell (1)

- Division of the cytoplasm and pinching of the cell membrane (1)

MS7:

- Chloroplasts contain chlorophyll needed for photosynthesis (1)

- Animals do not photosynthesize/obtain energy from sunlight (1)

MS8: Mitochondria (1)

MS9:

- Movement of particles from an area of high concentration to low concentration (1)

- Concentration gradient/difference drives diffusion (1)

- Factors affecting rate: temperature, particle size, distance (1)

MS10:

- Magnification: Enlarges the image, making small structures visible (1)

- Resolution: Ability to distinguish between closely spaced objects (1)

- Both allow detailed observation and precise measurements (1)
