Hints

Open one hint at a time and try again before the next.

Hint 1

Sugarcane is grown by planting pieces of its stem — what is this kind of reproduction called?

Hint 2

Compare a plant grown from a cutting with one grown from seed: time to fruit and similarity to parent.

Hint 3

For regeneration, think of which cells in Planaria make it possible.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. (i) Sugarcane reproduces by vegetative propagation (through stem cuttings with nodes).

    1 mark

  2. (ii) Advantage 1: plants raised this way bear flowers and fruits earlier than those grown from seeds.

    1 mark

  3. Advantage 2: the new plants are genetically similar to the parent, so desirable characters are preserved; it also lets seedless plants (e.g. banana) reproduce.

    1 mark

  4. (iii) Examples: rose and grapes (also banana, orange, jasmine).

    1 mark

  5. (iv) Regeneration needs specialised cells that can divide and differentiate into all tissues. Only simple organisms like Hydra and Planaria have such cells; complex animals lack them, so they cannot regenerate a whole body.

    1 mark

Answer: (i) Vegetative propagation; (ii) early flowering/fruiting, offspring identical to parent; (iii) rose, grapes; (iv) only organisms with specialised regenerative cells can regenerate.

Where the marks are

  • Names vegetative propagation (1 mark)
  • Two advantages (1 + 1 marks)
  • Two correct examples (½ + ½ marks)
  • Regeneration needs specialised cells present only in some organisms (1 mark)
