Plant begins to sprout. (Ans. C)

Explanation:

Seed germination is the process by which an organism grows from a seed. The most common example of seed germination is the sprouting of the seedling from the seed (angiosperm and gymnosperm plants).

Germination is usually the growth of plants contain within a seed. Seed germination depends on both external and internal environment conditions. Most important external environmental factors include:

1) Water: Water is required for germination.

2) Oxygen: It is required by germinating seed for metabolism.

3) Right temperature: It affects cellular metabolic and growth rates.

4) Light or darkness: It can be an environmental trigger for germination.  

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
