Question

What is the difference between pollen tube and style?

Answer 1

Pollen tube is a part of the male reproductive organ while the style is carried by the female reproductive organ. Pollen tubes and styles are parts of plants. Both pollen tubes and styles help in the reproduction process. Pollen tubes and styles are means of transporting gametes from one part to another in reproductive organs.

Complete answer:
Differences between pollen tube and style are:

Pollen tube	Style
Pollen tubes are the product of male gametophytes of seed plants. Male gametophytes are another name of male reproductive organs in plants.	Style is the extension of the pistil in the downward direction in the female reproductive organ of plants. The female reproductive organ in plants is called the carpel.
Pollen tube passes the style while transporting pollen grains to the ovules in the ovary. This means that the pollen tube is situated inside the style	Style is not present inside the pollen tube.
They help in the transportation of male gametes from pollen grains (from stigma in flowering plants) to the ovules. Ovules are present at the base of the pistil in the ovary. In gymnosperms (non-fruit and non-flower producing plant), ovules are transported directly through ovule tissues.	The style connects the ovary to stigmatic papillae. They are in the form of a tube and they might be absent on some plants. Style performs the function of carting female gamete or ovules from stigma to ovary where they are fertilised. Style is made of soft tissues.

Note: Pollen grains are the essential element for reproduction to take place in pants. They carry the male reproductive organs of the flowers. Each pollen grain has two male gametes. After reaching maturity, the cell split into two and one gametes are released as pollen and are transported by pollen tube to meet female gamete in the ovary where fertilisation takes place to form zygote and an endosperm.
