and conifers, the main dispersal stage is the seed. In the flowering plant the seed is enclosed inside a fruit, the structures of which help protect the seed and also assist its dispersal. Many flowering plants produce fruit that are intended to be eaten by animals, the seeds passing through the Seed Dispersal by wind, water, explosion, animals Seed size is an important factor.

Bidens pilosa (blackjack) The name, Bidens, is derived from the Latin bi, two, and dens, teeth, referring to the prominent barbed awns projecting from the apex of each seed. The specific epithet, pilosa, refers to the downy hairs on the stems and the leaves . Ballard (1986) has described the 'B. pilosa complex' with its centre of diversification in Mexico.

Seed dispersal is an important aspect of plant reproduction. If not suitably dispersed, seeds will germinate very close to their parent plant. This means that the seedlings must compete with one another and, of course, the parent plant for space, light, water and nutrients. BIOLOGY OF PLANTS - MBGnet Students will apply what they have learned about seed dispersal to create seeds with structures that suit them for dispersal in several ways. Procedure: 1. List 8–10 imaginary or real means of dispersal for seeds. Write each on a card. Make duplicate sets of cards as needed.

Seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds.
A: Seeds spread through the help of people, animals, wind and water. Some plants eject their seeds from their seedpods. One way in which seed dispersal occurs is when a seed gets caught in an animal's fur or a bird's feathers.

Exploding seed pods. - Biodiversity Shorts #7 - YouTube Triggered by the heat from the sun these seed pods have a novel way of dispersing their seeds. They burst open with explosive speed and fling the seeds within several feet. Although no where near ... Different Methods of Seed Dispersal in Plants - Gardenerdy Dispersal of seeds by various agents is very important for survival of the seed. Imagine if all the seeds of a plant fell in a small region below the tree. What will happen? The seeds will compete with each other and the parent plant for light, nutrients, and water. Thus, chances that not all seeds will grow in to healthy plants will be high.

After fruiting, the plant dries out completely – even the roots become brittle. This is a mechanism to promote ‘zoochory’ – the dispersal of seeds through animal or human movement. If the seeds catch onto a passing animal, the whole plant is easily pulled out of the ground and dragged along.
