G2 Phase
Differences between mitosis and meiosis
1. Meiosis has two rounds of genetic separation (mitosis twice) and cellular division while mitosis only
has one of each.
2. In meiosis, homologous chromosomes separate leading to daughter cells that are not genetically
identical. In mitosis the daughter cells are identical to the parent as well as to each other.
3. Meiosis produces gamete cells and mitosis produces diploid cells
4. Meiosis produces 4 cells and mitosis produces 2
a type of cell division that results in four daughter cells each with half the number of chromosomes of
the parent cell, as in the production of gametes.
Meosis
Prevents escape of cell contents; regulates exchange of materials between cytoplasm and extracellular
fluid; involved in intercellular communication
hair-like projection on a sperm cell that makes it motile
flagellum
Give shape and physical support to cell; anchor cells to each other and to extracellular material;
compartmentalize cell contents
intermediate filaments
Support microvilli and plasma membrane; involved in muscle contraction and other cell motility,
endocytosis, and cell division
microfilaments
, Form axonemes of cilia and flagella, centrioles, basal bodies, and mitotic spindles; enable motility of cell
parts; form trackways that direct organelles and macromolecules to their destinations within a cell
microtubules
process by which a cell takes material into the cell by infolding of the cell membrane
endocytosis
part of eukaryotic cell division during which the cell nucleus divides
characteristics:
1. development of an individual, composed of some 50 trillion cells, from a one-celled fertilized egg
2. growth of all tissues and organs after birth
3. replacement of cells that die
4. repair of damaged tissues.
Mitosis
Chromosomes become visable and releases into the cytosol, nuclear envelop dissolves, spindle fibers
form, centrioles lie at each pole of cell, and spindle fibers then tug the chromosomes back and forth
until they line up along the midline of the cell.
Prophase
the chromosomes line up across the center of the cell
Metaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
sister chromatids are generally identical
Anaphase
daughter chromosomes cluster on each side of the cell, rough ER produces a new nuclear envelope
around each cluster, and the chromosomes begin to uncoil and return to the thinly dispersed chromatin
form, mitotic spindle breaks up and vanishes.
Telophase
division of the cytoplasm to form two separate daughter cells
Cytokinesis
The time between two successive M phases.
Interphase
