Cell Cycle
Mitosis
Meiosis
Reproduction
Picture This!
100
The longest phase of the cell cycle
interphase
100
These protein filaments are generated by centrioles and attach to centromeres
spindle fibers
100
Meiosis occurs in these organs
reproductive organs
100
Female gametes
eggs (ovum)
100
prophase
200
DNA is replicated during this phase
"S" or Synthesis Phase
200
Chromosomes pair up and are visible during this phase
Prophase
200
An exchange of genes resulting in the genetic makeup of gametes.
crossing over
200
This process yields 2 diploid daughter cells
mitosis
200
What type of cell is shown?
what is a plant cell?
300
“Proofreading” the DNA after replication is a checkpoint that happens during during this phase of the cell cycle.
G2
300
A chromosome consists of these two “sisters”
chromatids
300
These separate during Anaphase II of meiosis.
What are “sister chromatids?”
300
This take place when sperm penetrates an egg in the fallopian tubes
fertilization
300
What phase is shown for D?
Telophase
400
Normal cell activities (like growth and the formation of organelles) take place during this phase.
G1 phase
400
Mitosis is necessary for 3 reasons, what are they?
What is
For growth of organisms
To replace damaged or dying cells
For asexual reproduction?
400
Fertilization by male and female gametes results in …
the formation of a zygote
400
Advantages :
Large population
Quick
Identical offspring
Disadvantages:
Less immunity/adaptability
Asexual Reproduction
400
What phase is E?
Metaphase
500
The spread of cancer cells through the blood/lymphe systems to show up in other parts of the body is known as …
metastasis
500
These organisms have the fastest rate of reproduction and can complete their cell cycle in as few as 20 minutes!
Prokaryotes
500
What is the end result of meiosis?
4 haploid daughter cells
500
Prokaryotic cells (bacteria) replicate in this process
binary fission
500
What is the term for this?
Apoptosis
