A) Transpiration helps in maintaining the concentration of the sap inside the plant body: The roots continue to absorb water from the soil. If excess water is not evaporated out, the sap would become dilute, preventing further absorption of water along with the minerals required by the plant
B) Gardener prefers to grow certain crops by vegetative method because of the following reasons: Reproduction by vegetative parts takes place in a shorter time. New plants, thus produced, spread very fast in a small area. It is a surer method of propagation.
C) The testes is located outside the abdominal cavity because sperm formation requires a temperature lower than the body temperature. It is because scrotum has a temperature 1-3 degree Celsius lower than the normal body temperature, which is essential for the production of sperm or male gametes
D) Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies.
E) The pituitary gland is considered the main endocrine gland. It is called the master gland because it produces hormones that control glands and many body functions including growth (growth hormone, Thyroid, and gonad stimulating hormone).
