Types of Reproduction and The Cell Cycle
One KEY part of the Cell Theory states that: “cells come from preexisting cells”. This process
of cellular reproduction is shown in all cells during The Cell Cycle
Why do organisms need cellular reproduction to take place?

Cell Reproduction is used to make new offspring …
THERE ARE 2 TYPES OF REPRODUCTION:
3.
__________________________
1.______________________________________________: ______parent, ________ gametes (sex cells), and offspring
___________________________________________________ to their parents. Mitosis is required.
4 Types of Reproduction:
a. When a unicellular organism makes a copy of its genetic material
and then splits into 2 cells. (bacteria)
b. When an offspring grows off the parent and then breaks off. (hydra)
c. It is a process by which new individuals arise without production of
seeds or spores.
Ex) Runners and shoots - (strawberries & potatoes)
d. An asexual cell that grows into a new offspring.
2. ________________________________________________: ________ Parents, ____________________________ are required,
and offspring ______________________________________________from their parents.
Sexual Reproduction requires the cellular reproductive process called:
Meiosis:
Gametes are sex cells (egg and sperm)
THE CELL CYLE:
The Cell Cycle varies depending on which type of cellular reproduction is used:
Includes 2 parts:
1.
____________________________________: when the cell grows and makes a copy of its DNA.
2.
_______________________________ or _______________________________ is the second part of the cell
cycle = Division of the Nucleus
a. If somatic cells are being replaced, if an organism is growing, or if asexual
reproduction is occurring ______________________________________is part of the cell cycle.
i. ____________________________________ Any biological cell forming the body of an
organism. (i.e. any cell not sperm or egg)
b. If gametes are being made then _______________________________ is the second part of the
cell cycle.
i. __________________________ : Sex cell that contains a single set of chromosomes.
(i.e. Sperm and egg cells in mammals)
The Cell Cycle with Mitosis:
1. Stages of Interphase:
a. _________________________ Cell growth and normal functions.
b. _________________________ Copies DNA
c. _________________________ Additional Growth
2. Mitosis
a. Includes _________________________, ___________________________
i. 4 phases of mitosis.
