Biology Quiz

Question 1

What did Hans and Zacharias Janssen do?

Answer 1

They both invented the first compound telescope (a telescope with more then 1 lens)

Question 2

What did Robert Hooke do?

Answer 2

Used a 3 lens microscope and observed the empty chambers in cork called cells.

Question 3

What did Antoinie Van Leeuwenhuck do?

Answer 3

Used a single-lens microscope and saw the movement of cells called bacteria.

Question 4

What is the field of view?

Answer 4

The field of view is what you see, its called the circle of light.

Question 5

What is spontaneous generation?

Answer 5

Life can emerge spontaneously from a nonliving matter.

Question 6

What did Louis Pasteur do?

Answer 6

He disproved the idea of spontaneous generation by doing the chicken broth experiment. It showed that when the chicken was warm it didn’t absorb bacteria, but when it was cold it absorbed bacteria.

Question 7

What did Robert Brown do?

Answer 7

Robert Brown discovered the structure of a cell, the nucleus, and its importance to cell function.

Question 8

What did M.J Schleiden do?

Answer 8

Discorvered that plant cells were made of cells and had a nucleus which was responsible for cell developemnt.

Question 9

What did Theodor Schwann do?

Answer 9

Discovered that all animal cells are made of cells and had a nucleus which was responsible for cell development.

Question 10

What did Rudolf Virchows do?

Answer 10

Discovered that all cells come from pre-existing cells.

Question 11

What are the 3 cell theories?

Answer 11

1. All living things are made up of one or more cells.
2. All life functions take place in cells.
3. All cells come from pre-existing cells.

Question 12

Cell membrane:

Answer 12

Controls what goes in and out of the cell.

Question 13

Cell wall:

Answer 13

A frame around the cell that provides for support and strength, just like the walls of a house.

Question 14

Nucleus:

Answer 14

The organelle that has the DNA of a cell and its genetic material.

Question 15

Cytoplasm:

Answer 15

Has nutrients required by the cell to carry on the life process.

Question 16

Nucleolus:

Answer 16

Controls the cell’s activities just like the brain controls human actions.

Question 17

Chloroplasts:

Answer 17

Contains chlorophyll which produces the green color: sites of photosynthesis.

Question 18

Vacuole:

Answer 18

Membrane-bound structures that serve to store nutrients, and fats, depending on the tissue type.

Question 19

Rough Endoplasmic Reticulum:

Answer 19

Produces protein for the rest of the cell to function.

Question 20

Smooth Endoplasmic Reticulum:

Answer 20

It doesn’t have ribsomes which means it doesn’t make protein for the cell, but produces lipids.

Question 21

Ribosome:

Answer 21

Help amino acids to link together to produce protein.

Question 22

Lysasome:

Answer 22

Membrane-bound cells which causes digestion to go on.

Question 23

Golgi Body

Answer 23

Prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell

Question 24

Mitochondria:

Answer 24

Make most of the energy for the cell. Energy production.

Question 25

Centrioles:

Answer 25

Organize microtubules that serve as the cell's skeletal system.

Question 26

4 Major types of organic compounds:

Answer 26

Lipids, carbohydrates, proteins and nucleic acids

Question 27

Chemical elements found in cells:

Answer 27

Carbon, hydrogen, oxygen, and nitrogen

Question 28

Trace elements (tiny amounts found in a cell):

Answer 28

Zinc, manganese, magnesium, and iron

Question 29

Similiraties in a plant and animal cell:

Answer 29

- Both have a cell membrane. - Both have genetic material (DNA)

Question 30

Differences between plant and animal cells:

Answer 30

- The vacuole of an animal cell is smaller than the vacuole of a plant cell. - An animal cell has only a cell membrane, while a plant cell has a cell wall AND a cell membrane. An animal cell doesn't have a cell wall. - The plant cell has chloroplasts, but the animal cell doesn't.
