Some plants have reproductive structures that help them reproduce using natural forces or animals. How does the reproductive structure shown here ensure the reproductive success of plants?
Answers
Answer:
To facilitate sexual reproduction in plants. A pollination is the process by which male gamates "pollen" transfered to female part of the plant, to carry out fertilisation. Pollination may be biotic or abiotic.
Biotic pollination involves transfer of pollen from one plant to other to facilitate fertilization by using a living agents. Animals are living agents. Animals play important role in plant reproduction. Animals visit flower in search of food, mating, habitat. Nectar in the flowers provide energy for growth, metamorphosis, reproduction etc. These animals takes away pollen from these flowers and transfer to other flowers of the same species and facilitate cross pollination.
Abiotic pollination involves transfer of pollen by non- living agents like wind, water etc. These are the natural forces.
Wind pollination (Anemophily): It is the most common form of abiotic pollination. It occurs in unisexual flowers. Pollen are produced in enormous quantity. Pollen are light weight not easily wetted by rain.
Water pollination (Hydrophily): It occurs in aquatic plants that release pollen in water.
Some plants have reproductive structures that help them reproduce using animals as a natural forces this called zoophily
Explanation:
Animal pollination (zoophily) :
Pollination that takes place by the agency of animals e.g , snail snake , birds , etc. birds pollinated flowers are of tubular , cup shaped or urn -shaped form ,bright in colour , large quantities of pollen grains present and rich in nectar . flowers are usually scentless and produces large amount of watery nectar.
zoophily consists of :
Entomophily :pollination by insects
Ornithophily :pollination by birds
Cheiropterophily: pollination by bats
Malacophily :pollination by bats
Myrmecophily :pollination by ants
Anthrophily: pollination by humans
