EVERYDAY SCIENCE

Detailed explanation-1: -Answer. Explanation: Seeds dispersed by water are found in light and buoyant fruits, while those dispersed by wind may have specialized wing-like appendages. Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals’ fur.

Detailed explanation-2: -Coconuts are well known for their ability to float on water to reach land where they can germinate. Similarly, willow and silver birches produce lightweight fruit that can float on water.

Detailed explanation-3: -Coconut, palm, mangroves, water lily, water mint, are a few examples of plants whose seed are dispersed by the water.

Detailed explanation-4: -Water dispersal The seeds float away from the parent plant. Mangrove trees live in estuaries. If a mangrove seed falls during low tide, it can begin to root in the soil. If the seeds fall in the water, they are carried away by the tide to grow somewhere else.

Detailed explanation-5: -There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus.
