NEET BIOLOGY

Detailed explanation-1: -Fruits play an important role in the seed dispersal of many plant species. In dehiscent fruits, such as poppy capsules, the seeds are usually dispersed directly from the fruits, which may remain on the plant. In fleshy or indehiscent fruits, the seeds and fruit are commonly moved away from the parent plant together.

Detailed explanation-2: -Seeds are dispersed in several different ways. In some plants seeds are housed within a fruit (such as apples or oranges). These fruits, including the seeds, are eaten by animals who then disperse the seeds when they defecate. Some fruits can be carried by water, such as a floating coconut.

Detailed explanation-3: -One of the main functions of a fruit is to spread the seeds and allow the plant to reproduce. Therefore, all flowering plants produce fruit, regardless of whether the fruit is edible, sweet, or soft.

Detailed explanation-4: -Dispersal may occur by a number of different means, including gravity (basically, a simple means of dispersal involving the seed falling and potentially rolling downslope a short distance), wind, water, animals, and ballistic dispersal (adaptations that launch seeds from the fruit).

Detailed explanation-5: -The most common methods are wind, water, animals, explosion and fire. Have you ever blown on a dandelion head and watched the seeds float away? This is wind dispersal. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind.
