Concept explainers

Oogenesis

The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.

Cell Division

Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

PLEASE ANSWER THE FOLLOWING QUESTIONS: 1. In figure 1 locate the mitotic zone or region of cell division. Next, identify mitotic stages visible in figure 2. Note down visible structural changes occurring at various stages of mitosis, namely: prophase (early and late) metaphase, anaphase (early and late) and telophase (early and late). 2. Point the specific mitotic stages that can be seen in the enlarged image of onion root tip cells undergoing cell division (figure 2). 3. Search for a diagrammatic illustration of the different stages of meiosis, examine/study carefully the changes occurring in each stage. Note how these stages assemble or differ from those of mitosis. 4. Then, summarize the structural changes occurring in each stage of mitosis and meiosis in a tabular form.

Q1: Prior to going through meiosis, the nucleus would look like which letter? (Write just the letter below.) Q2: Next, the mitotic spindle fibers start to organize into centrosomes and these centrosomes pull away from each other, but since these images just show the nucleus, you don't see that here. While the mitotic spindle fibers are reorganizing, the DNA chromosomes start to condense, which you do see here. This is represented by what image? Q3: Once the DNA is completely condensed and organized into chromosomes, homologous chromosomes pair up in a process known as synapsis. This is represented by what image? Q4: Synapsis sets the homologous chromosomes up for crossing over when homologous chromosomes exchange parts of their DNA with each other. This is represented by what image Q5: At this point, the nuclear envelope is completely dissolved and no longer visible. The homologous chromosomes are lined up in the middle by the mitotic spindle fibers. This happens as the mitotic…
