What is cell division and why do cells need to divide the larger they become?
Cell division is the process by which cells divide into two new daughter cells. The larger a cell becomes, the more demands the cell places on its DNA. A larger cell is less efficient in moving nutrients and waste materials across the membrane.
100
In order for a cell to divide, what must the cell do first?
Duplicate its genetic information
100
What is the longest phase of Mitosis?
Prophase
100
How is the cell regulated?
The cell cycle is controlled by regulatory proteins both inside and outside the cell.
100
If a cell has 12 chromosomes, how many chromosomes will each of its daughter cells have after mitosis and cytokinesis?
12
200
What is cell differentiation?
During the development of an organism, cells differentiate into many types of cells.
200

What happens during mitosis

cell splits the nuclei to duplicate

200

T or F: cells are specialized what the first appear to carry out specific functions

FALSE: all sell start as unspecialized and go through differentiation .

Where are sister chromatids attached?
Centromere

What is a centriole?
Centrioles are tiny paired structures that are located in the centrosome. Spindle fibers extend from this region to separate the duplicated chromosomes.

What is a tumor?
A mass of cancer cells

Name an advantage and disadvantage of asexual reproduction.
Advantage-- reproduce quickly Disadvantage-- lack of genetic diversity
400
What is the difference between asexual and sexual reproduction?
Asexual reproduction is the production of genetically identical offspring from a single parent. Sexual reproduction involves the fusion of two separate parent cells. The offspring produced inherit some of their genetic information from each parent.

What happens during the M phase of the Eukaryotic cell cycle?
Mitosis and Cytokinesis

What are growth factors?
Growth factors stimulate the growth and division of cells.

what happens if a cell fails to go through cytokinesis

It will be one large cell with 2 nuclei.

What is cyclin?
Cyclin is a protein that regulates the cell cycle.
500
Describe the three parts of interphase.
G1-- Cell Growth S (synthesis)-- DNA replication G2-- Preparing for cell division
500
Name the phases of Mitosis in order.
Prophase Metaphase Anaphase Telophase
500
How do cancer cells differ from other cells?
Cancer cells do not respond to the signals that regulate the growth of most cells. As a result, the cells divide uncontrollably.

what is apoptosis?

a programmed cell death- damaged, unneeded or dangerous cell systematically self destruct
