If a sporangium develops from a single cell, the development of sporangium is known as
1 heterosporangiate
2 homosporangiate
3 eusporangiate
4 leptosporangiate
Explanation:
Sporangium is a spore producing structure in plants. When a sporangium develops from a single cell, the development of sporangium is known as leptosprangiate. When the sporangium is developed from different epidermal cells instead of single epidermal cells, is known as eusporangiate. Homo sporangiate is development of one kind of sporangium. Heterosporangiate is the formation of different kind of sporangium.

In the homeostatic control of blood sugar level, which organs function respectively as modulator and effector?
1 Liver and islets of Langerhans
2 Hypothalamus and liver
3 Hypothalamus and islets of Langerhans
4 Islets of Langerhans and hypothalamus
Explanation:
Hypothalamus and islets of Langerhans acts as modulator and effectors in the homeostatic control of blood sugar level. A modulator is an organ that modulates the homeostasis and effectors is an organ that brings it into effect. The homeostatic control of the blood sugar level is done by glucagon and insulin.

Anthesis is a phenomenon which refers to
1 stigma receptivity
2 dehiscence of anthers
3 viability of pollen
4 opening of flower bud
Explanation:
Anthesis is a phenomenon which refer to the opening of flower bud. It includes the maturation of flower parts means elongation of style, maturation of stamen, formation of pollen and ovule, and also petal colours. After this flowers are ready for pollination and post pollination process. So, this is also called flowering period and it makes a flower functional.

Hypothalamus and islets of Langerhans acts as modulator and effectors in the homeostatic control of blood sugar level. A modulator is an organ that modulates the homeostasis and effectors is an organ that brings it into effect. The homeostatic control of the blood sugar level is done by glucagon and insulin.
