Meiosis
At the end of Meiosis, what is produced?
4 haploid gamete cells, genetically different from each other
At the end of Mitosis, what is produced?
2 diploid daughter cells that are genetically identical
In sexual reproduction, a fertilized egg is referred to as what?
Zygote
This is a resting phase and not part of the cell cycle.
G0
Cellular senescence occur after about ____ rounds of cell division.
50
Meiosis is the process by which haploid gametes are produced where?
Gonads
During which stage of mitosis does the nuclear envelope reform?
Telophase
Name three limiting factors of asexual reproduction.
Resources, Waste, Predators
This is the phase of interphase where the cell spends most of its life
G1
Name the shape, amount, and location of prokaryotic chromosomes.
Shape - circular
Amount - singular
Location - Cytoplasm
What stage does crossing over take place?
Prophase I
During which stage of mitosis does the chromatin condense into chromosome?
Prophase
Type of asexual reproduction that occurs when a parent cell splits into two identical daughter cells of the same size
Binary Fission
These are the phases included in interphase
G1, S, G2
Name the shape, amount, and location of eukaryotic chromosomes.
Shape - linear
Amount- multiple
Location - nucleus
What occurs during Metaphase I?
Homologous pairs line up in the center/equator of the cell
Remember: this only happens in Metaphase I
After mitosis, Cytokinesis splits up the cytoplasm. To do this, in animal cells, what unique structure is first formed?
Cleavage furrow
Type of asexual reproduction that occurs when a bubble-like bud grows and develops while attached to the parent cell before breaking away
Budding
This phase is responsible for DNA replication
S
What occurs during step 1 of Binary Fission?
DNA is replicated, resulting in two identical chromosomes
In which stage of Meiosis do sister chromatids separate and move to opposite poles of the cell?
Anaphase II
What structures are responsible for moving the chromosomes during mitosis?
Spindle fibers
Type of asexual reproduction where a parent organism breaks into pieces, and each piece develops into a new organism.
Fragmentation
What happens in the G2 phase? (3 things)
- shorter period of growth
- organelles reproduced/manufactured
- preparations for mitosis
What occurs during step 3 of Binary Fission?
Two daughter cells are produced that are genetically identical to the parent cell
