Reproduction in Plants Test - 2

The roots of sweet potato are used in vegetative propagation. Vegetative propagation is a form of asexual reproduction of a plant. Only one plant is involved and the offspring is the result of one parent. The new plant is genetically identical to the parent.

Air layering is performed in litchi plant. It is a method of propagating a plant by girdling or cutting part way into a stem or branch and packing the area with a moist medium, as sphagnum moss, stimulating root formation so that the stem or branch can be removed and grown as an independent plant.

Shoot system is formed by scion in grafting, whereas root system is formed by stock. Grafting is a horticultural technique whereby tissues from one plant are inserted into those of another so that the two sets of vascular tissues may join together.

Rose plant is usually propagated by stem cutting. The cutting produces new roots, stems, or both; thus becomes a new plant independent of the parent.

During pollination, after the pollen grain has landed on the stigma, it creates a pollen tube which grows down the style until it reaches the ovary.

Female gametophytes of flowering plants develop within the ovule (megaspore) contained within an ovary at the base of the pistil of the flower.

Anther is not a part of a carpel. It is a part of stamen.

Transfer of pollen from anther to stigma is called pollination. It is unique to the angiosperms, the flower-bearing plants.

The development of seedless fruit in an unfertilised flower is called parthenocarpy.Seedlessness is seen as a desirable trait in edible fruit with hard seeds such as pineapple, banana, orange and grapefruit.

Plumule is called the future shoot of a germinating seed. From it, true leaves originate.
