(b) grow from root
(c) grows from buds (eye)
(d) stem cutting
(e) explosion
​

Answer 1

Answer:

Rose - stem cutting

Bryophyllum - grows from bud

Pea - new plants arise along the edges of the leaf

Carrots and beets - explosion

Potato - grow from root

Answer 2

Answer:

Column A→ Column B

1. Rose→ (d) stem cutting

2. Bryophyllum→ (a) new plants arise along the edges of the leaf

3. Pea→ (e) explosion

4. Carrots and beets→ (b) grow from the root

5. Potato→ (c) grows from buds (eye)

Explanation:

• 1. Rose→ (d) stem cutting- Varieties of Roses are propagated by stem cuttings. This nursery method is called- grafting.

• Grafting is beneficial in plants such as roses which fail to produce viable seeds.

• 2. Bryophyllum→ (a) new plants arise along the edges of the leaf- In Bryophyllum, plantlets arise from the margins of the leaves called leaf buds.
• When these fall on moist soil, they can grow into a whole new plant. These leaf buds are a means of vegetative propagation.

• 3. Pea→ (e) explosion- Some plants such as Peas, Lupins and Violas have pods that explode when ripe and shoot out the seeds i.e. spread their seeds by exploding them out of pods.

• When the seeds are ready, the pod dries up. When the pod dries, the inside of the pod dries faster than the outside.

• Pea pods often use mechanical dispersal-explosion means the seeds shoot far from the parent plant and don't rely on animals or other factors.

• 4. Carrots and beets→ (b) grow from the root- Vegetables such as carrots and beetroots are planted underground giving rise to new plants. They are a means of vegetative propagation i.e. underground root modification.

• 5. Potato→ (c) grows from buds (eye)- Potatoes are grown vegetatively using underground stems. Potato eyes or buds are vegetative structures giving rise to new plants.

Thus, the correct sequence of matching-

1. → (d)

2. → (a)

3. → (e)

4.→ (b)

5. → (c)
