Answer:
A. Transport of materials in xylem
Xylem tissue helps in the transport of water and minerals
Water is transported upwards from roots to aerial parts of plants
Transport in xylem requires physical forces such as transpiration pull.
B. Transport of materials in phloem
Phloem tissue helps in the transport of food.
Transport of food in phloem requires energy in the form of ATP.
Food is transported in both upward and downward directions.
Answer:
Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>
Explanation:
Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP. The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.
Answer:
They produce the:
• Tropic hormones (Thyroid stimulating hormone, Adrenocorticotropic hormone ACTH, Luteinizing hormone LH and Follicle-stimulating hormone FSH).
• The growth hormone and
• Prolactin.
Explanation:
The pituitary gland, found just below the hypothalamus consists of an anterior and posterior part, which release hormones which are either proteins or polypeptides
The secretion of these hormones are stimulated by chemicals produced by the hypothalamus and transported to the pituitary in the bloodstream.
The anterior pituitary glands hormones consists of several tropic hormones that regulates the activities of the other endocrine glands(through homeostatic mechanisms); also the growth hormone and prolactin.
