Study Notes
Interphase
- Chromatin is present within the nucleus.
- Chromosomes remain invisible during this phase.
- This phase prepares the cell for division by growing and duplicating organelles and DNA.
Prophase
- Nuclear membrane begins to fade.
- Spindle fibers are formed, facilitating movement of chromosomes.
- Chromatin condenses into visible chromosomes.
- Centromeres divide, allowing chromosomes to move towards opposite poles.
Metaphase
- Chromosomes align along the equator of the cell.
- Sister chromatids line up at the cell's equatorial plane.
Anaphase
- Sister chromatids separate and begin to move apart toward opposite poles of the cell.
Telophase
- Spindle fibers disappear as the cell prepares to divide.
- The phase reverses the processes of prophase, leading to the decondensation of chromosomes.
- Begins cytokinesis, where the cytoplasm divides.
- In animal cells, the membrane starts to pinch inward.
- In plant cells, a cell plate forms across the center.
- A new nuclear membrane forms around each set of chromosomes.
- The cytoplasm further divides, resulting in two distinct daughter cells.
Cytokinesis
- Refers to the division of the cytoplasm during cell division.
- Occurs at the end of telophase, marking visible differentiation of two daughter cells.
Sister Chromatid
- Each half of a duplicated chromosome is called a sister chromatid.
Centromere
- The structure responsible for connecting two sister chromatids, playing a crucial role in their separation during mitosis.
Cell Plate
- Forms across the center of plant cells during the end of telophase, leading to the division of the cytoplasm.
