ASEXUAL REPRODUCTION
Date ________________
Forms of asexual reproduction include the following:
1. Budding: ___________________________________________________________________
2. Vegetative reproduction:_______________________________________________________
3. Parthenogenesis:_____________________________________________________________
4. Fragmentation: _______________________________________________________________
Bacteria and protist cells divide asexually using binary fission while all other eukaryotic cells divide
by mitosis.
Interphase and Replication
Each cell spends most of its life (90% of the time) in INTERPHASE, the period after mitotic division
has formed a cell and before it divides again.

Interphase - Description
Stages of Mitosis in a Plant Cell
Biologists describe mitosis as a series of four distinct stages: Prophase, Metaphase, Anaphase and Telophase.
Provide a detailed description of the events that occur at this given stage.
Prophase - Description
Metaphase - Description
Anaphase - Description
Telophase – Description
Describe the events that occur in a plant cell during cytokinesis
The Outcome of Mitotic Cell Division
As a result of mitosis, each new nucleus (whether the cell is from a plant, a protist, or an animal)
contains an exact copy of the DNA present in the original nucleus. That is, each new offspring cell
has exactly the same _________ and kind of ____________. In unicellular organisms
(paramecium), mitotic cell division __________ the population sizes. In multicellular organisms
__________ and ____________ depend on mitotic cell division.
The Need for Mitotic Cell Division
Explain the importance of mitotic cell division in humans.
