‘He who plants a tree, plants the green Earth’.
• Plants are living things which are very useful to us.
• They need air, water, soil, and sunlight to live.
• They cannot move from place to place, but their leaves show movement to capture light from the sun and their roots show movement towards the ground.
• Their seeds can be carried by animals or blown by the wind.
• Plants can grow from different parts of the plant like seeds, stems, roots and leaves.Read More...
GROWING PLANTS FROM SEEDS
• All seeds cannot grow into new plants.
• Some seeds are eaten up by birds and insects.
• Some seeds get destroyed by rain or wind.
• Some seeds do not get sufficient air, water, or warmth to grow.
• If the seed survives and gets the right amount of water, air, and warmth (from the sun), it will produce a baby plant or seedling.
• The process in which a plant emerges from a seed and begins growth is called germination.Read More...
• Many plants scatter their seeds in order to ensure that they do not grow too close to one another.
• The process by which the seeds are scattered away from the mother plant is called dispersal.
• Nature has its own way of dispersal of seeds.
The ways by which dispersal of Seeds take Place:
A. Dispersal by wind:
• Seeds of certain plants are very light and have wings or hair on them.
• These seeds are easily carried away by wind.Read More...
GROWING PLANTS FROM ROOTS, STEMS, AND LEAVES
• Plants can grow not only from seeds but also with the help of their roots, stems, and leaves.
A. Roots that can grow into New Plants:
• The plants whose roots can grow into new plants are:
• Carrot, radish, turnip, beetroot, dahlia, sweet potato
B. Stems that can grow into New Plants:
• Potato and onion are the stems that grow into new plants.Read More...
GROWING PLANTS FROM SPORES
• Some plants do not have seeds.
• They grow with the help of tiny structures called spores.
• These plants reproduce with the help of spores.
• Fungi, fern, mushroom, horse tail
(1) Mushrooms have no seeds of their own. But they still grow on the soil. How is this possible?Read More...
