Organization Of Plant Dispersal by Water:

Dispersal by Water:

The seeds of plants that grows in or near water are carried far away by water.
Lotus plants grow in the pools and ponds.
Their fruit fall in water when ripen and carried to a long distance by water currents. Lotus fruits is like a sponge and floats on the surface of water. Its seeds drops at the new places and grow into new plants. Coconut trees grow along the sea coast. Hair like fibers, present on coconut fruit, help it to float on water.
Its fruits floats long distances along tides.
When it reaches some land mass, it grows into a new plants.

Dispersal  by Animals and Men:

Men, monkeys, squirrels and birds eat juicy fruit. They take the fruit with them to distant places and throw away seeds after eating  the fruits. New plants grow from these seeds. Some fruits have hard and small seeds.
These seeds are eaten along-with fruit, for example guava. Such seeds are not digested.
If animals goes far away, they are excreted along-with faces. In this way, they are dispersed.
Some fruit have rough surface or bristles on them. They stick to clothes, feathers of birds and hair of animals and are carried to distant places where they fall and so are dispersed
