Question

Describe the structure of microsporangium with diagram.

Hint:

Microsporangium is essential for male gamete formation in plants.

Answer 1

Step 1: What is a Microsporangium?
A microsporangium is the pollen sac in seed plants where male gametes (pollen grains) are produced. It is a part of the male reproductive organ (stamen) in angiosperms and conifers.
Step 2: Structure of Microsporangium.
The microsporangium consists of: 1. Epidermis: The outermost layer, which is protective. 2. Tapetum: The innermost layer that nourishes the developing microspores. 3. Microspore Mother Cells (PMC): These cells undergo meiosis to form microspores (pollen grains).
Step 3: Diagram (if applicable).
(Include diagram of microsporangium)
A diagram would show the layers of the microsporangium and the arrangement of the microspore mother cells.
Step 4: Conclusion.
The microsporangium is vital for the formation of pollen, which is necessary for fertilization in seed plants.
Final Answer: \[ \boxed{\text{Microsporangium consists of epidermis, tapetum, and microspore mother cells.}} \]
