Sample questions
-
1.How does total (evident) plasmolysis differ from incipient plasmolysis?
- A.Total plasmolysis is reversible; incipient plasmolysis is irreversible.
- B.Total plasmolysis involves complete protoplast shrinkage; incipient is the initial stage.
- C.Incipient plasmolysis occurs in hypotonic solutions; total in hypertonic.
- D.Total plasmolysis requires energy; incipient does not.
-
2.Xylem
- A.Centre of the vascular bundle.
- B.Outer side of the vascular bundle.
- C.On the margins of leaves
- D.On the margins of roots.
-
3.What is the biological term for the process of mixing of two different substances or molecules?
- A.Osmosis
- B.Diffusion
- C.Active transport
- D.Imbibition
-
4.How is plasmolysis utilized in practical applications such as preserving food or killing weeds?
- A.By adding salt to meat or pickles, water is drawn out of bacterial cells, killing them, and excessive salts around weeds cause water loss from root cells.
- B.By soaking food in water to prevent bacterial growth and diluting soil salts to protect weeds from dehydration.
- C.By freezing food to halt bacterial activity and using herbicides to chemically break down weed cell walls.
- D.By exposing food and weeds to sunlight, which dries out cells and prevents microbial or plant growth.
-
5.Which of the following correctly represents the labelled parts of a root hair in a diagram?
- A.Cell wall, Cell membrane, Cytoplasm, Nucleus, Vacuole, Root hair extension
- B.Cell wall, Chloroplast, Cytoplasm, Nucleus, Vacuole, Root hair extension
- C.Cell wall, Cell membrane, Mitochondria, Nucleus, Vacuole, Root hair extension
