Cells & Tissues, Tissue Healing & Organ Systems Quiz

Question 1

What does ribosomes produce?

Answer 1

Protein

Question 2

How many mitochondria are in the average mammalian cell?

Answer 2

It varies with the cells activity type. More active cells (ex heart) will require more

Question 3

This structure modifies, packages and distributes proteins destined for secretion or intracellular use

Answer 3

Golgi apparatus! The “post office”

Question 4

The process of building new proteins, using the information on the mRNA is called…

Answer 4

Translation!

Question 5

The functions of the flagella and cilia include

Answer 5

Locomotion or moving material past the cell

Question 6

What is the purpose of mitosis?

Answer 6

To create new identical daughter cells to replace the old ones

Question 7

List the steps of mitosis
1. Interphase - normal functioning cell morphology
2.
3.
4.
5.
6. Cytokinesis - mitosis is completed

Answer 7

PMAT!
2. Prophase: nucleus dissolves and chromatin condense, creating chromosomes
3. Metaphase: chromosomes line up in the middle of the cell
4. Anaphase: spindles move chromosomes to opposite sides of the cell
5. Telophase: chromatin unwind and a nuclear envelope forms

Question 8

Function of the nucleus

Answer 8

Control center of the cell, stores the cell’s DNA

Question 9

Function of rough ER

Answer 9

It creates protein, then chemically modifies (if needed), and packages it (likely to golgi app)

Question 10

T/F: blood is epithelial tissue

Answer 10

False! Blood is connective tissue with a liquid matrix

Question 11

T/F: Cutaneous membrane is another word for skin

Answer 11

True!

Question 12

T/F: Smooth muscle occurs in muscles that cannot be consciously controlled

Answer 12

True

Question 13

Endocrine glands…

Answer 13

Produce hormones which are secreted into the blood stream

Question 14

What is the goal of inflammation?

Answer 14

To prevent further damage and remove harmful agents

Question 15

Cardiac muscle contains…

Answer 15

Intercalated disks uniting cells

Question 16

What are the five steps of inflammatory? Describe.

Answer 16

1. Pre hemostasis: limits vessels in the injured/flamed area
2. Vasodilation: pulls with blood cells (this is the stinging sensation that’s similar to itchiness)
3. Swelling: the body has a surge of fluids to affected area
4. Clotting: this is when the body bruises
5. Phagocytosis: waste is ‘eaten’ away
   Capillaries and blood flow return to normal!
