Lesson 3-Cytology

Question 1

Cytology is what?

Answer 1

The study of cells

Question 2

Cell theory has 3 basic principles. Fill in the blanks

1. All living things are composed of _____ or more living things.
2. The _______ is the basic unit of organization of organisms.
3. All cells come ________ cells.

Answer 2

1. One
2. Cell
3. Existing

Question 3

All cells have a cell membrane.

True or False?

Answer 3

True

Question 4

All cells have a cell wall?

True or false?

Answer 4

False, cells ALWAYS have a cell membrane but NOT always a cell wall. A cell wall makes the cell rigid and not able to move well.

Question 5

There are two types of cells.
1. Prokaryotic

And

2. Eukaryotic

Which type of cells do plants, animals and humans have?

Answer 5

Eukaryotic cells they are more complex cells.

Question 6

What are examples of Prokaryotic cells?

Answer 6

Bacteria and green algae.

Question 7

What are the 3 main parts of a eukaryotic cell?

Answer 7

Cytoplasm
Cell membrane
Nucleus

Question 8

Which of the following is NOT true about cells?

1. All cells have the same organelles.
2. Cells come in a variety of sizes.
3. some organisms have many different shaped cells within the organism.
4. Multicellular organisms often have specialized cells that each have their own job.

Answer 8

1. All cells have the same organelles.

Question 9

The plasma membrane is made up of two layers of phospholipids.
True or false?

Answer 9

True

Question 10

The plasma membrane is composed of only phospholipids?

True or false?

Answer 10

False

Question 11

The plasma membrane is the ____________
boundary of the cell.

Semi-permeable or closed?

(Permeable means it lets things pass through)

Answer 11

Semi-permeable (it keeps toxins out, but lets somethings through like water. Remember water is every important to us and our cells need it.)

Question 12

Cell diffusion is a type of ________ transport.

Active or passive?

Answer 12

Passive

In diffusion molecules move from high areas of concentration to low areas of concentration.
Think about the food coloring dissolving in the cup of water.

Question 13

What does NOT impact he rate of diffusion?

Color
Temperature
Concentration
Molecule size

Answer 13

Color

Question 14

Osmosis is a type of active or passive transport?

Answer 14

Passive transport

Question 15

Cytoplasm is everything found OUTSIDE or INSIDE the nucleus?

Answer 15

Outside the nucleus

Question 16

The nucleus is the _________________

Answer 16

Master control center of the cell. It is also where the DNA is found.

Question 17

Ribosomes line up amino acids to produce _____________?

Answer 17

Proteins

Question 18

Mitochondria are the ___________ __________

Of the cells.

Answer 18

Power plant of the cells

Question 19

Golgi apparatus is the ___________ ___________

Of the cells.

Answer 19

Shipping centers

Question 20

Lysosomes are the cell’s ___________ centers.

Answer 20

Recycling

Question 21

Vacuoles are the _________ within the cell

Answer 21

Containers within the cells that hold various substances.

Question 22

Rough endoplasmic reticulum tags what?

Answer 22

Tags PROTEINS with a molecule to be transported to the Golgi apparatus.

Question 23

Smooth endoplasmic reticulum synthesizes __________ and __________and also helps with cellular detoxification.

Answer 23

Lipids and steroids
