Question

The anther contains
(a)Sepals
(b)Ovules
(c)Carpel
(d)Pollen grains

Answer 1

It is the male microgametophytes of seed plants that produce male gametes after meiosis. This structure is formed with the anther in a plant which is usually oval-shaped.

Complete answer:
Anthers contain the male gametes called pollen grains inside them. The anther is a terminally bilobed structure. The two anther lobes are separated by a deep groove in front and attached by a band of vesiculated tissue called Connective. Each anther is a four-sided tetragonal structure consisting of four microsporangia. Microsporangia forms pollen sacks which on maturity become a field with pollen grains.

Additional Information:
-The cell wall of the pollen grain called Sporoderm consists of two layers, exine, and intine.
-The exine is the outer layer made up of sporopollenin (one of the most resistant organic materials known). It can withstand high temperatures, strong acids, and alkali.
-The calyx (sepals) is the outermost whorl of a flower generally green leaf-like structure, protects the flower in the bud stage.
-Corolla is the second whorl of the flower and its every individual segment is known as petals. They are brightly colored, have a fragrance which makes the flower more attractive.
-The androecium is the third whorl inner to the corolla. It is the male reproductive system.
-The gynoecium is the fourth and the last whorl of the flower. It is the female reproductive part of the flower which is composed of one more or more carpel.
-Carpel has three parts namely the ovary, which bears one or more ovules. Style, which connects the stigma to the ovary. Stigma acts as a receptor organ for pollen grains.

So the correct answer is, “Pollen grains.”

Note:
-A Flower normally has four whorls, namely Calyx (sepals), Corolla (petals), Androecium (Stamen), Gynoecium (Carpel).
-The androecium is composed of Stamen which consists of filament and anther.
