The disease caused by the fungus Aspergillus fumigatus is: MCQ with Answer and Explanation

Explanation:
Excretion is the elimination of nitrogenous waste products (urea, uric acid, ammonia) and other metabolic wastes from the body, primarily by the kidneys. Digestion is breakdown of food, circulation is transport, respiration is gas exchange and energy release. Excretion maintains homeostasis of body fluids and prevents toxic accumulation.

Explanation:
Apical meristems at root and shoot tips contribute to primary growth (increase in length). Intercalary meristems, located at nodes and leaf bases, also aid in elongation, especially in grasses. Lateral meristems (vascular cambium, cork cambium) cause secondary growth (increase in girth). So both apical and intercalary meristems are responsible for length increase.

Explanation:
Phyllotaxy is the pattern of leaf arrangement on the stem. In sunflower (and many other plants like mustard), the phyllotaxy is alternate, meaning a single leaf arises at each node. In opposite phyllotaxy (e.g., guava), two leaves arise at a node, and in whorled (e.g., Nerium), more than two leaves arise at a node.
