An organism that has two or more cells.

Question 9

What are the three main components of every cell?

Answer 9

• Cell membrane
• Cytoplasm
• Organelles

Question 10

What is cell membrane?

Answer 10

It is separated cells from other cells and the cell contents from the outside and it is very thin.

Question 11

What is Cytoplasm?

Answer 11

It is the “factory floor” of the cell. It is a substance that fills the space between the cell membrane and it is 75 - 90 % water.

Question 12

What is Photosinthesis?

Answer 12

It is chemical process that plants use to make glucose and oxygen from carbon dioxide and water.

Question 13

What are cell structures?

Answer 13

All cells regardless of which type of organism they are found in, share the same basic structure.

Question 14

What is a DNA?

Answer 14

It contains the instructions for every job your cells need to do and is passed from one generation to the next.

Question 15

What are the 4 vey important membrane-bound organelles in the cell?

Answer 15

Mitochondria, Ribosomes, Chloroplasts and Vesicles.

Question 16

What is Mitochondria?

Answer 16

It is the powerhouse organelle of a cell; the site of energy production.

Question 17

What is Ribosomes?

Answer 17

They are cell organelle where protein production takes place.

Question 18

What is Chloroplasts?

Answer 18

Chloroplasts are organelles found in plant cells that transforms solar energy into chemical energy.

Question 19

What are Vesicles?

Answer 19

Vesicles are organelles that are used by plant and animal cell to store water, nutrients and waste products.

Question 20

What are Fungal cells?

Answer 20

Fungal cells are not the same as plants cells.

Question 21

What are Plant cells?

Answer 21

They use their chloroplasts to photosynthesis and need cell walls to provide structure.

Question 22

What are Animal cells?

Answer 22

Animal cells are singled-celled or unicellular organisms, such as bacteria, are made of one cell only.

Question 23

What are Protists?

Answer 23

Protists are a diverse group of organisms that are mostly unicellular.

Question 24

What is a Microscopy?

Answer 24

it is the use of investigation with a microscope.

Question 25

What are the two main types of microscopes?

Answer 25

Light and electron microscopes.

Question 26

What is light microscopes?

Answer 26

It uses light rays

Question 27

What is electron microscopes?

Answer 27

It uses small particles called electrons.

Question 28

What is the function for the eyepiece?

Answer 28

This is the lens closest to your eye. It usually has a magnification of 10x.

Question 29

What is the function for the objective lens?

Answer 29

There are three lenses of different strength which can be used to magnify the image more clearly. 4x, 10x, 40x

Question 30

What is the function for the stage?

Answer 30

This is the place where you put a microscope slide and the clips hold the slide in place.

Question 31

What is the function for the Diaphragm?

Answer 31

controls the amount of light that goes onto the microscope slide.

Question 32

What is the function for the Light?

Answer 32

The light source projects light onto the microscope slide.

Question 33

What is the function for the Base?

Answer 33

This is very heavy to keep the microscope from falling over.

Question 34

What is the function for the Body tube?

Answer 34

This holds the eyepiece lens above the stage.

Question 35

What is the function for the Fine focus knob?

Answer 35

This is used to focus the image so it is very sharp and clear.

Question 36

What is the function for the Course focus Knob?

Answer 36

This is used to focus the image so that you can see it clearly.

Question 37

What is Mitosis?

Answer 37

It is the division of the nucleus into 2 nuclei, each with the same number of chromosomes.
