Question

Which one of the following statements is correct?

• A. In tomato, fruit is a capsule
• B. Seeds of orchids have oil-rich endosperm
• C. Placentation in Primrose is Basal
• D. Flower of tulip is a modified shoot.

Answer 1

The correct option is D

Flower of tulip is a modified shoot.

The correct option is D.

Explanation of correct option:

1. In some plants, the underground stem is changed to produce the bulb.
2. The stem's subsurface modification primarily functions as a food storage and reproductive system.
3. Bulb-producing plants undergo a transformation that makes their leaves meaty. There is not much stem left.
4. The tulip is a very well-known example of a plant with bulbs.
5. The sprout is made by altering the tulip's blossom.
6. Leaves make up the bulb.

Explanation of incorrect options:

Option A:

1. The fruit tomato is a berry.
2. The tomato's whole pericarp is edible.
3. The pericarp is the modified ovary wall or the fruit wall.

Option B:

1. Orchid seeds are not endospermic.
2. Non-endospermic seeds are seeds that do not include endosperm.
3. The endosperm is consumed early in the development of non-endospermic seeds.
4. The nourishment is stored in the cotyledons of Non-Endospermic seeds.

Option C:

1. A free-standing plant is a primrose.
2. In primrose, the wall between the carpels initially resembles axile placentation but eventually disappears.
3. As a result, the central axis converts into the free central axis.
4. The placenta is situated on this free central axis.
5. Contrarily, in the basal placentation, the placenta develops close to the base of the ovary.

Final answer: The correct statement is, “Flower of tulip is a modified shoot.”
