Question 1:

100 trillion cells

What does DNA stand for?

Question 2:

Deoxyribonucleic acid

What happens during Metaphase?

Question 3:

Paired chromosomes align in the middle of the cell

Two identical cells are formed in this stage of mitosis

Question 4:

Cytokinesis

Paired chromosomes are attached at this spot

Question 5:

centromere

Chromosomes separate and move to opposite ends of the cell

Question 6:

Anaphase

Spindle fibers break down and chromosomes lose their shape during this phase

Question 7:

Telephase

What term matches the following definition..Long piece of coiled DNA and proteins

Question 8:

Chromosome

List 3 life processes of the cell

Question 9:

Growth, movement, reproductionCould also include: waste

removal, exchange of gases, intake of nutrients, etc.

What is the largest zoom on the objective lens using our compound microscopes in class?

Question 10:

40x

If the power of the objective lens is 40 times, and the power of the ocular lens is 10x, what is the power of the microscope?

Question 11:

400x

What are the stages during mitosis and which one takes the longest time? Explain your reasoning.

Question 12:

Prophase, Metaphase, Anaphase, Telephase, CytokinesisProphase takes the longest time

because it has two phases – more happens during prophase than any other phase of mitosis

List two differences between plants and animal cells

Question 13:

Plant cells have larger vacuolePlant cells contain chloroplastPlants contain cell wallsAnimal cells have centriolesAnimals cells have specialized

compounds

I am a jelly-like substance that fills the cell and surround the organelles. I also contain nutrients required by the cell to carry on its life process. What am I?

Question 14:

cytoplasm

Question 17:

Ocular lens

Why are fluorescent substances added to cells when using the compound microscope?

Question 18:

When cells are placed in UV light the fluorescent substance will glow, making the parts of the cell more visible.

To improve contrast between parts of the cell and its background

Early prophase, late prophase, metaphase, anaphase, telephase, cytokinesis

Question 28: What is a chromosome?

Coiled DNA

Question 29: What happens to the cell when it does not go

through apoptosis.

In turns into cancer cells and keeps spreading

Question 30: What environmental factors can contribute to

mutated cells? What can these factors lead to? Factors can include smoking, the

SUN, inhaling toxic chemicals, etc.These factors can lead to various

types of Cancer

Question 31: What would happen if our vacuoles stopped

working in our cells?

The bodily functions require water in our system would cease functioning (cells cannot obtain water)
