Cell Growth & Reproduction Flashcards
Is there a limit to the size of a cell?
Yes
What is there between the volume and area of a cell?
A critical relationship
What is a parent cell?
A cell that has grown and must divide
What are daughter cells?
2 identical cells
What is fission?
The process where 1 cell splits into 2 cells
What is different about cancer cells?
Cancer cells reproduce cells at an uncontrollable rate and are unrelated to the cells around them
What can mitosis also be known as?
Karyokinesis
Mitosis is NOT what?
Not the actual division of a cell
What is mitosis?
All things that happen to a cell up to the actual division of a cell
What is mitosis?
And is what process from Protein Synthesis?
The duplication of nuclear material (Replication)
Mitosis happens to every cell in your body but…
Sperm and egg cells
Do cells grow?
Yes
What are the 2 phases of fission?
Mitosis
Cytokinesis
What is cytokinesis?
The actual splitting of cells
What are the 5 phases of mitosis?

I I P Picked M Many A Apples T Today
How many chromosomes do humans have?
46
How many pairs of chromosomes do humans have?
23
What kind of a core does a protein have?
Protein
What are inside chromosomes?
DNA
What is the 1st part of a cell life?
Mitosis
What is the 2nd step of the cell life?
Cytokinesis
What is the 3rd step of cell life?
G1 phase
What is the 4th step of the cell life?
S-Phase
What is the S-Phase an example of?
Replication dealing with DNA
What is the 5th step of the cell life?
G2 phase
What is the general name of the G1 phase, S-phase, and G2 phase?
Interphase
What are the 2 types of reproduction?
Asexual and sexual
What are the two things about asexual reproduction?
- 1 cell splitting into 2 cells
- not 2 cells forming 1 cell
What are two examples of asexual reproduction?
1) Binary Fission (Mitosis)
2) Budding (Yeast)
What is the different between binary fission and budding with asexual reproduction?
The cells do not divide evenly in budding like they do for binary fission
What is the definition of sexual reproduction and what does it mean?
-fission of specialized cells
means, the coming together of sperm and egg cells
Gametes are ???
Sexual reproductive cells
What are the 2 sexual reproductive cells?
Fe- egg (ovum)
M- sperm

Ovum
What is fertilization?
The actual fusion of gametes
What is a zygote?

How many homologous pairs do males have?
How many do females have?
Males- 22 pair
Females- 23 pair

What happens in meiosis?
The # number of chromosomes is cut in half
What does a haploid cell start with, and what does it end with?
A haploid cell starts with 1 Diploid cell, and end with 4 haploid cells
