Which of the following statements regarding the development of the male gametophyte in angiosperms is correct?
- A.The microspore nucleus undergoes meiosis to form the vegetative and generative cells.
- B.The generative cell divides by mitosis to form two male gametes before pollination in all species.
- C.The vegetative cell is larger, contains abundant food reserve, and has an irregularly shaped nucleus.
- D.The pollen tube is formed by the generative cell after it reaches the stigma.
Show correct answer & step-by-step solution
Correct answer: C — The vegetative cell is larger, contains abundant food reserve, and has an irregularly shaped nucleus.
Solution
- The microspore undergoes mitosis, not meiosis, to form the vegetative and generative cells.
- In 60 percent of angiosperms, pollen is shed at the two-celled stage, meaning the generative cell divides later.
- The vegetative cell is larger and contains abundant food reserves with an irregularly shaped nucleus.
- The pollen tube is formed by the vegetative cell, not the generative cell.
- Hence the answer is (C).
