Meiosis can be best observed in A. Megaspores B. Microspore mother cells C. Anther wall D. None of these
Hint: Cell division: It is a very important process in living organisms. During cell division: DNA replication and cell growth take place. Cell cycle: It is a sequence of events by which a cell duplicates its genome, synthesizes the other constituents of the cell and divides into two daughter cells. All these events are under genetic control.
Complete answer: To solve this question, we need to know about cell division and cell cycle Cell cycle: It is a sequence of events by which a cell duplicates its genome, synthesizes the other constituents of the cell and divides into two daughter cells. The cell cycle is divided into two phases: 1. Interphase (95%) 2. M Phase (5%) The interphase is further divided into three phases: 1. Gap 1 2. S phase 3. Gap 2 M phase is further divided into four different phases: 1. Prophase 2. Metaphase 3. Anaphase 4. Telophase Meiosis: It is a special type of cell division that reduces the chromosome number by half results in the production of haploid daughter cells. Meiosis involve two sequential cycles of nuclear and cell division called meiosis 1 and meiosis 2 The sporogeneous tissue which may divide in various planes and finally separate from each other during the development of microsporangium is known as microspore mother cell. Meiosis can be best observed in microspore mother cells. The formation of haploid microspores takes place through meiosis. This process is known as microsporogenesis. The haploid microspore formed from a single microspore mother cell is arranged in the form of four cells called microspore tetrad. Megaspore: Megaspore or large spore germinates into a female gametophyte which produces egg cells.
So, the correct option is option B. Microspore mother cell.
Note: Prophase is the first phase of mitosis. It is the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Metaphase: Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible.
