Full steam ahead!
We learned about different types of cells (the basic unit of life) and how different types of cells get energy to perform functions.
Now...
How and why do cells grow and divide?
Ch. 10: Cell Growth & Division
10.1 Cell Reproduction: chromosomes & their structure
10.2 Mitosis
10.3 Regulation of cell growth & division (cancer)
Chapter 10 Vocabulary
Begin 10.1 Cell Reproduction
The adult human body produces about 2 trillion cells per day that are exact copies of the cells they replace! (what kind of cells?)
Learning Objective: I can explain why and how cells reproduce.
Cell division is necessary for the growth, repair, and maintenance of organisms (continuity of life)
A cell's activity, including division, is directed by its DNA
Each new copy of a cell has the same DNA as the original cell, so DNA is also copied in cell division
gene - segment of DNA that codes for RNA & protein; the molecular unit of heredity
chromosome - in a eukaryotic cell, structure found in the nucleus and made up of DNA & protein; prokaryotes have a ring of DNA
chromatid - one of the 2 strands of a chromosome that become visible during cell division
centromere - the region of the chromosome that holds the two sister chromatids together during cell division
Take a look at the structure & draw for processing
