WORD
DEFINITION
1. Cell Cycle The life cycle of a cell Pg 92
2.
The structures that DNA is organized into
Chromosomes
Pg 92
Cellular reproduction in prokaryotic cells. Means "Splitting into two 3. Binary Fission parts"
Pg 92
Each chromosome of a pair of similar chromosome 4. Homologous Chromosomes
Pg 93
The two copies of the chromosome once it is duplicated 5. Chromatids
Pg 93
Where the chromatids are connected 6. Centromere
Pg 93
7. Mitosis The complicated process of separating duplicated chromosomes Pg 93
8. Cytokinesis The process where the cytoplasm splits in two Pg 95
WORD
DEFINITION
9. Budding A type of asexual reproduction, where a piece of the parents body Pg 612 develops into an independent organism
10.
A type of asexual reproduction, where the organism breaks into two or
Regeneration more parts, each growing into a new organism that is genetically identical
(fragmentation) to the parent
Pg 612
11. Sexual reproduction
Pg 613
The production of offspring by combining the genetic material of more than one parent
12. Asexual reproduction
Pg 613
A single parent has offspring that are identical to itself
13. Sperm Pg 613
The male sex cell
14. Egg Pg 613
The female sex cell
15. Zygote Pg 613
The new type of cell that is made when an egg's nucleus fuses with a sperm's nucleus
16. Spores Small reproductive cells that are protected by a thick cell wall Pg 256
WORD
DEFINITION
17. Sex Cells Specialized cells that combine to form a zygote, they have half the normal Pg 114 number of chromosomes, one of each pair.
18. Meiosis Pg 115
A process where the chromosomes are copied and separated in such a way that each daughter cell has half the normal number of chromosomes.
19. Sex The chromosomes that carry the genes that determine gender. Chromosomes
Pg 119
20. Fertilization The joining of an egg and a sperm Pg 613
21. Cell Plate The primary structure the leads to the new cell membranes between two
Pg 95
plant cells during cytokinesis
22. Spindle Fibers that connect to the centromeres of the chromosomes and that Fibers help push and pull the chromosomes apart during mitosis
23. Interphase The cell is at "rest" Chromosomes and other cell materials are copied
24. Prophase First stage of mitosis, nuclear membrane breaks apart, the centrioles move to opposite sides of the cell
WORD
DEFINITION
25. Metaphase Second phase of mitosis, the chromosomes line up along the equator of the cell
26. Anaphase Third phase of mitosis, the chromatids separate and are pulled to opposite sides of the cell
27. Telophase Forth and final phase of mitosis, nuclear membranes reform around the chromosomes and they unwind.
