Cytology

Question 1

What are the three different types of cell transport

Answer 1

1. Bulk transport - pinocytosis or phagocytosis
2. Active transport - uses ATP
3. Passive transport - diffusion or osmosis

Question 2

Is phagocytosis and pinocytosis endocytosis or exocytosis

Answer 2

It is endocytosis

Question 3

What are the 5 steps of cell Transport

Answer 3

1. Diffusion - substance moves from the High concentration to Low concentration
2. Osmosis - semipermeable membrane
3. Active transport - From Low to High concentration, ATP, e.g. how cardiac muscles work
4. Phagocytosis - cell can ‘eat’ particles that are too large to be absorbed by diffusion etc
5. Pinocytosis - ‘cell drinking’ liquids rather than solid (similar to phago)

Question 4

Answer 8

Homologous

Question 9

What are gametes in mitosis

Answer 9

Gametes are haploid cells, they only have one set of chromosomes and they transmit genetic information and

Question 10
