Module 2 Part 1: Cell Division Mitosis
Terms in this set (13)
List the 2 types of cell division in eukaryotes
Mitosis & Meiosis
Why do organisms need new cells?
Growth, replacing old or damaged cells, and for reproduction
What is chromatin?
Long, thread-like pieces of DNA in the nucleus
What are chromosomes and how many do humans have?
Chromosomes are formed when chromatin gets shorter and smaller, before cell division; humans have 46 chromosomes in each cell
List and briefly describe each of the 3 parts of Interphase.
G1 - The cell grows and carries out its normal functions
S - Synthesis or replication of DNA occurs
G2 - Cell grows, carries out normal functions and prepares to divide
List the parts of a chromosome
3. short arm
4. long arm
What happens during the mitotic phase?
The cell divides
List the main stages of cell division.
Interphase, Mitosis and Cytokinesis
Cell division of the nucleus, DNA and chromosomes
Division or splitting of the cell's cytoplasm
List the stages of mitosis
interphase & prophase, metaphase, anaphase, telophase
What happens during cytokinesis and when does it occur?
The cell begins to pinch in at the cleavage furrow, thereby, splitting cytoplasm, this happens about the same time as telophase
How do the end products of mitosis compare to the original parent cell?
The end products (diploid/daughter cells) are the same as the original parent cell
