3. the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.

6. : Farmers spray to mitigate crop damage caused by pests. A pest is any biological organism, including weeds, pathogens, and arthropods, that interferes with the production of crops affecting quality and/or yield.

7. there are three type of crops which are RABI , KHARIF , ZAID

KHARIF :-

1. Kharif crops are sown early-May – usually at the beginning of the first monsoon rains.
2. Requires hot weather and a large amount of water to grow.
3. Cotton, groundnut, maize and rice are examples of Kharif crops.

RABI :-

1. Rabi crops are sown around mid-November – preferably after the monsoon rains
2. Requires warm climate for seed germination and cold climate to grow.
3. Barley, gram, peas and wheat are examples of Rabi crops.

1. Such crops are grown between the Kharif and Rabi seasons, i.e., between March and June.
2. these crops mature early
3. .Cucumber, pumpkin, bitter gourd, and watermelon are zaid crops.

1. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire. Dandelion seeds float away in the wind.
