Question

what are the different methods of speed dispersal and how are the seeds adaptes for the same?​

Answer 1

$\huge\underline\bold\blue{ƛƝƧƜЄƦ}$

• There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.

• Some seeds have hooks on them that allow them to attach to animal fur or clothes. Some seeds are able to float in water.

• Some seeds are light and have wings or thin hairs that allow them to be carried away by wind. Some seeds are eaten by animals and deposited in areas away from the parent plants.

Answer 2

Answer:

Autochory

Autochorous plants disperse their seed without any help from an external vector, as a result this limits plants considerably as to the distance they can disperse their seed.

Gravity

Barochoryor the plant use of gravity for dispersal is a simple means of achieving seed dispersal.

Ballistic dispersal

Ballochoryis a type of dispersal where the seed is forcefully ejected by explosive dehiscence of the fruit.

Allochory

Allochory refers to any of many types of seed dispersal where a vector or secondary agent is used to disperse seeds.

Wind

Wind dispersal (anemochory) is one of the more primitive means of dispersal

Water

Many aquatic (water dwelling) and some terrestrial(land dwelling) species use hydrochory, or seed dispersal through water.

By Animals

Animals can disperse plant seeds in several ways, all named zoochory.

By human

Dispersal by humans (anthropochory) used to be seen as a form of dispersal by animals

Recent research points out that human dispersers differ from animal dispersers by a much higher mobility based on the technical means of human transport.
