Cell Cycle/Mitosis
Mitosis produces how many cells?
2 cells
What phase is the cell in the picture on the board in?
Interphase
Copies of chromosomes are called...
Chromatids/Sister chromatids
How many parents are involved in asexual reproduction?
1 parent
4 cells
If a cell has 62 chromosomes and goes through mitosis, how many chromosomes will each of the new cells have?
62 chromosomes
Draw a picture of anaphase
See picture
The structures that attach to the centromere and pull chromatids toward opposite sides of the cell
Spindle fibers
Does asexual reproduction produce cells that are identical, or unique?
Identical
If a diploid cell starts with 12 chromosomes, how many chromosomes will the cells created from meiosis have?
6 chromosomes
Mitosis produces what TYPE of cells?
Somatic cells
What phase is the cell in the picture on the board in?
Prophase
Organized DNA that contains genes for traits
Chromosomes
This type of asexual reproduction involves prokaryotes like bacteria splitting in two
Binary fission
What type of cells does meiosis produce?
Gametes
This phase of the cell cycle happens before mitosis. Chromosomes copy during this phase
Interphase
Draw a picture of cytokinesis
See picture
A cell with half the number of chromosomes is called a ____cell
Haploid
What is the difference between internal fertilization and external fertilization
Internal = Sperm and egg meet inside of female organism
External = Sperm and egg meet outside (laying eggs)
Why do gametes have to go through meiosis and not mitosis?
Meiosis produces cells that have half the number of chromosomes and are unique. When the sperm and egg cells combine they will have a full set of chromosomes.
This structure forms during telophase in plant cells to separate them
Cell plate
What phase is the cell in the picture on the board in?
Telophase
The "crossing over" process that happens during Prophase I in Meiosis is called...
Recombination
Why can asexual reproduction be more effective for an organism than sexual reproduction?
Takes less time/energy, quicker, produces more offspring
Why is recombination important in meiosis?
Recombination allows genetic information to transfer between homologous chromosomes. This is important so that when the cell divides, each of the four new gametes will be genetically different.
