Cytokinesis
______ refers to the division of the nucleus
Mitosis
Which organisms have a single circular chromosome
Prokaryotes
Name a type of cell division that occurs in prokaryotic cells, in which a parent cell divides into two identical daughter cells.
Binary fission
True or false: In binary fission, four daughter cells are produced
False
What are phases of binary fission
DNA Replication, chromosome segregation, and separation.
True or False: Eukaryotic cells don’t go through mitosis
False
Asexual reproduction involves how many parents
1
Sexual reproduction involves how many parents
2
Which process involves to gametes uniting to form a single cell, such as when a sperm combines with an egg to form a zygote.
Fertilization
Methods of asexual reproduction include…
Fragmentation, binary fission, and budding.
______ is the type of asexual reproduction that occurs in yeast
Budding
Which type of reproduction produces two identical daughter cells
Binary fission
What is not a method of asexual reproduction: Binary fission, budding, fertilization, or fragmentation
Fertilization
Meiosis is associated with what kind of reproduction
Sexual
Mitosis is associated with what kind of reproduction
Asexual
What does external sexual reproduction look like
A lot of eggs and very little care
What does internal reproduction look like
Few young and a lot of care
Gamete definiton
Sex cells, egg and sperm
Zygote definiton
The combination of sex cells, the combination of two gametes
Reproduction definition
Producing more of the same type of organism
Genetic variation makes __________________ more likely to survive.
The whole population
Each gamete contains ______ of the parent’s DNA
Half
______ reproducers are all at risk of environmental change
Asexual
Fragmentation definition
A type of asexual reproduction where the parent organism breaks into fragments and each piece develops into a new organism
Budding definition
Type of asexual reproduction where an offspring pinches off from the parent cell
Parthenogenesis definition
An asexual reproductive process where an unfertilized egg cell grows into a new organism
Prokaryote definition
Single-celled organism that doesn’t have a nucleus or other membrane-bound organelles
Eukaryotes definition
Organism that has cells containing a nucleus and other membrane bound organelles
Single celled organisms use ______ for asexual reproduction
Mitosis
Multicellular organisms use ______ for growth and repair of body cells
Mitosis
What do unicellular organisms use meiosis for
Nothing ; they don’t use meiosis
Multicellular organisms use ______ to produce sex cells (sperm and egg) for sexual reproduction
Meiosis
In mitosis, the final cells, ___ cells are made, that are produced are ____________ as the original cell
2 ; Exactly the same
All plants reproduce ______, but not all plants use ______ and ______.
Sexually ; flowers ; pollen

1
How much DNA is in an egg and sperm cell compared to the original immature sex cell
Half (goes from 4 to 2)
In meiosis, the final cells are ______ to the original cell
Different
How many rounds of cell division are there during meiosis
2
