Question

Draw the diagram of a flower and label the four whorls. Write the names of gamete-producing organs in the flower.

Answer 1

Flower:

1. Each flower has a floral axis.
2. On this floral axis, the reproductive organs and accessory organs are carried.
3. The accessory organs serve to attract pollinating insects as well as protect the reproductive organs.
4. There are four distinct whorls of flower parts - calyx, corolla, androecium, and gynoecium.

Calyx:

1. The flower's outermost whorl, known as the calyx, is made up of sepals.

Corolla:

1. The corolla is made up of petals. Typically, vividly colored petals draw insects for pollination.

Androecium:

1. An androecium is made up of stamens. Every stamen represents the male reproductive system.
2. Each stamen is made up of an anther and stalk.

Gynoecium:

1. One or more carpels make up the gynoecium, the female reproductive part of the flower.
2. .Three components make up a carpel: the stigma, the style, and the ovary.
3. The style is an extended tube that is attached to the larger basal portion of the ovary.
4. The stigma, which is the pollen grains' receptive surface, is typically at the tip of the style.

Gamete producing organs of flower:

1. The anther and ovary are the gamete-producing organs in the flower.
2. The anther is the male gamete-producing organ.
3. Normally, each anther has two pollen-sac chambers in each of its two lobes.
4. The ovary is a female gamete-producing organ.
5. The ovary is the enlarged basal part of the carpel.
