Sexual Reproduction In Flowering Plants

A false fruit is one where some parts other than the ovary contribute to fruit formation.
In apple, the thalamus (receptacle) becomes fleshy and forms the major part of the fruit.
So both assertion and reason are correct, and the reason explains the assertion.

In maize, both male (tassel) and female (ear) flowers are found on the same plant — making it monoecious.
Pollination can occur between flowers of the same plant (geitonogamy) or between different plants (xenogamy).
Therefore, maize fits the criteria given.

Step 1: Some aquatic plants undergo pollination through water, a process known as hydrophily.
Step 2: In such plants, pollen grains are modified for floating and travel.
Step 3: Zostera}, an aquatic plant, produces long, ribbon-like pollen grains which help in floating in water and reaching the stigma.
Step 4: This structure is not found in wind or bird-pollinated flowers or gymnosperms.
