Answer AND Explanation:
A variety of organic and inorganic compounds serve very important roles in living things. The various organic compounds constitute the structures of the body and regulate the chemical processes going on inside it.
Carbohydrates are essential for life since they are oxidised during respiration to release energy. Glucose is the most common respiratory substrate. They are also building blocks of polysaccharides such as starch and cellulose in plants and glycogen in animals.
Lipids are important because they can be oxidized during respiration to release energy. They provide twice the amount of energy for the same weight of carbohydrates. They also act as insulators, source of metabolic water and are major components of cell membranes.
Proteins are important structural components of the cytoplasm and various supportive tissues in the body, transport substances, make up hormones and are used as a source of energy through respiration.
Answer:
Explanation:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
There are many grains of starch in the cortex because it represents the reserve food material of plants.
This source of food material is consumed during plant metabolism, as food when plants are under stress, or as an energy source in seed germination and early seedling stages.
The cortex, in plants, is a vascular tissue responsible for the transport of food (processed sap) from the leaves to the rest of the plant .
Starch grains are the most common solid particles that plant cells develop within plastids.
Assimilation starch is a temporary product of photosynthesis and is formed in chloroplasts, while reserve starch is formed in amyloplasts, which are contained in parenchymal cells of the cortex, in vascular tissues of stems and roots, in the pith of stems, in fruits, leaves, fleshy cotyledons and in modified stems, such as tubers and rhizomes.
Starch is the main energy and carbon reserve in plants, supplying the energy and carbon skeletons necessary for the plant's metabolism during periods of darkness, when photosynthesis is inactive.
Therefore, we can conclude that starch grains (ergasstic substances) are found in abundance in the cortex because it represents a reserve of essential molecules for the functioning and maintenance of the cellular structure.
