How are lotus plants dispersed?
Lotus seeds are dispersed by water. Explanation: Lotus is an aquatic plant, hence, its seeds fall on the water surface, floats, and gets carried away through the water current.
Is Lotus dispersed by wind?
These are called agents of dispersal. a) Wind : Small and light weight seeds can be carried long distance by the wind to the place which is suitable for growth. Some seeds have wing like structure that help them float in the air . b) Water : The seeds of plants like lotus and coconut are dispersed by Water.
What are the dispersed by wind?
Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds. They don’t float away but flutter to the ground.
How does Lotus and coconut seeds dispersed?
Dispersal by water – the coconut seed has a thick coat of fibre that enables it to float in water, the Lotus fruit has a spongy part that enables it to float. these plants grow near water and their seeds are carried to far off places by water.
How do you separate lotus flowers from seeds?
Break open the pods with your fingers. Discard the pods. Rub your fingers gently over the hourglass-shaped seeds to separate the seeds from the remaining leaves and other plant debris.
What do you mean by seed dispersal give examples of seeds that are dispersed by wind water and animals one example each?
Seed Dispersal by Gravity In some cases, the fallen fruit is carried by other agents like water, wind, birds or animal and helps in the dispersion of seeds. Apples, Commelina, canna, coconuts, calabash, passion fruit are a few examples of plants whose seeds are dispersed by Gravity – A force of attraction.
What are examples of seed dispersal by wind?
The seeds of the orchid plant, dandelions, swan plants, cottonwood tree, hornbeam, ash, cattail, puya, willow herb, are all examples of plants whose seed are dispersed by the wind. In this method of seed dispersal, seeds float away from their parent plant.
How does wind affect seed dispersal?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. The longer a seed stays in the air, the farther it can be blown by the wind, helping the plant species widely scatter its offspring.
How are seeds dispersed by animals wind and explosion?
Some times tiny seeds fly in air and settle down at a place and germinate .. Birds will leave the waste then in of the seeds germinate. some times groups of seeds in a pack will scatter/explode .
Why can’t all seeds be dispersed by the wind?
Answer: All seeds cannot be dispersed by seeds as for this they need to be light weight and have hairs or wings so that wind can carry them off. all seeds don’t have all these features so they are dispersed by different methods as per their characteristics.
How are Nelumbo nucifera related to the protea flowers?
According to the APG IV system, N. nucifera, N. lutea, and their extinct relatives belong in Proteales with the protea flowers due to genetic comparisons. Older systems, such as the Cronquist system, place N. nucifera and its relatives in the order Nymphaeles based on anatomical similarities.
When do you harvest Nelumbo nucifera seed pods?
Seeds and seed pods can be harvested when they turn black four to eight months after planting. After sun drying for two to three days, they are processed by mechanical tools to separate seed coats and embryos. The rhizomes mature to a suitable stage for eating in approximately six to nine months.
Where does the Nelumbo nucifera live in the world?
Nelumbo nucifera. It has a very wide native distribution, ranging from central and northern India (at altitudes up to 1,400 m or 4,600 ft in the southern Himalayas ), through northern Indochina and East Asia (north to the Amur region; the Russian populations have sometimes been referred to as ” Nelumbo komarovii “),…
How is Nelumbo nucifera used in wastewater treatment?
Nelumbo nucifera shows high potential for usage in wastewater treatment removing polluting compounds and heavy metals. It is able to grow in variable water conditions and in low light intensity.
