Definitions
The process by which a cell divides into 2 new daughter cells (genetically similar)
Cell Division
Cell Division increases/decreases the volume of the cell
Decreases
When a living thing grows, what happens to its cells?
Produces more cells/Multiply/Increase in number
Name 2 types of reproduction
1. Asexual Reproduction
2. Sexual Reproduction
Every cell must copy its genetic information_______ cell division begins.
before
Formation of a new organism
Reproduction
The ratio between surface area of the cell membrane and volume increases/decreases in each of the daughter cells.
Increases
Cells grow in size, but eventually, after growing to a certain point, they ________
divide
Define Sexual Reproduction
The fusion of two separate parent cells where offspring are produced.
Genetic information is bundled into packages of DNA known as _______________
chromosomes
The production of a genetically identical offspring from a single parent is known as ______ ________.
Asexual Reproduction
Before a cell divides, what must happen
It makes a copy of its DNA (genetic material)

Define Asexual Reproduction
The production of genetically identical offspring from a single parent.
DNA in prokaryotes is found in the __________, whereas DNA in eukaryotes is found in the ________.
cytoplasm; nucleus
The fusion of two separate parent cells
Sexual Reproduction
TRUE OR FALSE
Offspring produced by sexual reproduction inherit some of their genetic information from each parent.
TRUE
Name 2 reasons cell size is limited:
Hint: library/town analogy
1. As a cell grows, the demands on the DNA increase. The cell gets too big to take care of itself (library)
2. The surface area to volume ratio of the cell decreases and materials can't enter/exit the cell as needed
Offspring produced by sexual reproduction inherit some of their ______ ________ from each parent
genetic information
Chromatin is a complex of __________ and _______
chromosome(DNA) and protein
Use an analogy to describe the 2 reasons a cell size is limited:
Library/Traffic Jam:
As a town grows, more demands are made on the library to a point where the library can't provide enough books (cell DNA - as cell grows, DNA can't meet the needs of the cell)
As a town grows, traffic will clog the roads and becomes difficult to move goods in/out. (cell - can't get oxygen & nutrients in/ waste out)
Cell division in a multicellular organism often leads to:

Most _______ and ________ reproduce sexually.
plants and animals
(& some single-celled organisms)
Name the 3 main events of the cell cycle:
1. a cell grows
2. prepares for division
3. divides to form two daughter cells
