Question

The bees carry the pollen back to its colony on
A. Its body
B. Its middle legs
C. Its front legs
D. Its rear legs

Answer 1

Hint:
Now before we get into the answer, we will see the definition of pollen.
Pollen is a collection of microspores present in seed plants and typically appears as fine dust. Each pollen grain is a microscopic body with a distinctive shape and structure that forms in seed-bearing plants' male structures before being carried by a variety of factors (including such breeze, water, insects, and so on.) to the female structures, in which fertilization takes place.

Complete step by step answer:
The majority of pollen grains have three distinct parts. The nuclei necessary for fertilization are located in the middle cytoplasm. The inner layer, defined as the intine, and the outer layer, known as the exine, are the other components that form the wall of the grain.
The intine includes cellulose or hemicellulose, at least in part. Exine, the outermost and toughest layer, is extremely resistant to disintegration; treatment with high temperatures, potent acids, or potent bases has no impact on it. Sporopollenin is the name given to the exine's components.
The pollen grain's interior components are rapidly broken down, but the exine layer, and hence the pollen grain's overall structure, is easily preserved in a variety of sediment types; the level of preservation may vary with different environments.
Therefore, the bees carry the pollen back to their colony on their rear legs.

Option ‘D’ is correct

Note:
The anthers of the stamens of flowers create pollen in angiosperms. It develops in the microsporophylls of the microstrobili of gymnosperms (male pollen cones). One or even more vegetative cells and a reproductive cell make up pollen. The male gamete is not present in a pollen grain. A reproductive cell is the source of pollen in angiosperms and some gymnosperms, where the vegetative cell creates the pollen tube that expands to meet the unfertilized ovules.
