- Cell wall
- large vacuole
- chloroplast
Name three parts of a animal cell that a plant cell does not have.
- Small vacuoles
- Centrioles
- lysosomes
What are the phases of mytosis?
“IPMAT”
interphase “active rest”
Prophase “prepare”
Metaphase “middle”
Anaphase “apart
Telophase “two”
try to give a brief explanation of each
What are reasons why cells reproduce?

growth, repair, replacement, reproduce
Name one type of cancer and give a brief explanation.
Bladder cancer:
signs: blood, blood clots and urine.
diagnosis: a cytoscopy
treatment: surgery to remove cancer cells
Prevention: don’t smoke, drink plenty of liquids
How do you find FVlp
measure the feild of view under the microscope under cm, then transfer to mm if easier.
How do you find FVmp
FVmp = FVlp x Mlp/Mmp
How do you find the FVhp
FVhp=FVlp x Mlp/Mhp
How do you estimate specimen sizes?
- what power is it being viewed under?
- What is the size of the field of view for that power?
- How many times does the object fit across the field?
$. divide field size by the number that fit.
What is a karyotype?
A persons complete set of chromosomes.
What can karyotypes be sued to determine?
genetic problems as the cause of a disorder, also gender (what gender you are assigned when born) NOT WHAT GENDER YOU ACTUALLY ARE. OR WHO YOU IDENTIFY AS.
How many chromosomes do normal humans have (humans without a genetic disorder or any kind)
46
What are types of tissue in the human body?
Epithelial, muscular, nervous and connective.
Briefly explain how the human arm moves.
The brain sends a signal to your muscles, which then pull or push on tendons to then move the bones at the joints.
What are the three types of stem cells?
