Plants are living. There are a lot of biochemical reactions occurring in them, which of the following reaction is light dependent?
Sunlight has a very important job in photosynthesis. The energy captured by chlorophyll can be used in photosynthesis to make sugar. When a plant gets limited sunlight, photosynthesis slows down. This also means that the plant might not be getting enough sugar—its energy source.
'Kitchen of plant refers to which part of plant
The development of seed into seedling which further develop to plant is called
The seed contains the future plant, an embryo. The embryo develops into a seedling under favourable conditions. This process of development of seedlings from a seed is called as germination.
Which of the following is harmful for crops?
Hail damage has been known to be harmful to trees, plants, crops and flower beds. Even small pieces of hail combined with strong winds can be damaging to vegetation such as lettuce, cabbage and spinach. This can leave farmers who rely on this type of produce as one of their main sources of income to become financially devastated.

What part of coconut seed enable it to float in water for dispersal to distant places?
What would you plant in soil to get a new rose plant in your garden?
Read the given statements carefully and find the correct answer
Statement I: All plants have fruits that produce a large number of seeds
Statement II: Some plants reproduce by vegetative propagation.
Statement I: incorrect
Most plants produce a large number of seeds because most of the seeds don't get dispersed and some of them don't grow. After all these reasons there are less chances for the growth of a seed. Therefore some plants produce a large number of seeds so that one day some of these seeds will grow into a plant.
Statement II : correct
b) In nature, some plants reproduce mainly vegetatively while others rely almost totally on sexual reproduction.
Photosynthesis in plant does not require?
The seeds dispersed by air/wind will have
(i) Dispersal by wind - Light seeds or hairy seeds and hairy fruit get blown off with the wind to far away places. Examples: Sunflower, Maple, Drumstick etc.
(ii) Dispersal by water: Fruits or seeds which develop floating ability in the form of spongy or fibrous.
