Answer 1

Carbon dioxide.

Question 2

What are organisms made up of?

Answer 2

Tiny building blocks known as cells.

Question 3

What is the cell membrane?

Answer 3

The thin skin around the cell that holds the cell together and also controls what goes in and out of it.

Question 4

What do you do when you need to see the slide with greater magnification?

Answer 4

You switch to a higher powered objective lens.

Question 5

What does a group of different tissues come together to make?

Answer 5

An organ.

Question 6

What is respiration?

Answer 6

The process of releasing energy from glucose.

Question 7

Where should you place the microscope and why?

Answer 7

Place it near a window or a lamp so the light shines through the hole in the stage.

Question 8

Give one physical adaptation of an Amoeba.

Answer 8

They have a contractile vacuole to collect excess water and squeeze it out at the cell membrane.

Question 9

What is a multicellular organism?

Answer 9

Organisms composed of many cells.

Question 10

Give one physical adaptation of a Euglena.

Answer 10

They have a tail like structure called flagellum that can help them swim.

Question 11

How should you angle the mirror?

Answer 11

Angle the mirror so the light shines up through the hole in the stage.

Question 12

Once you have clipped a side onto the stage, what should the slide have?

Answer 12

The objects you want to look at (stuck to it).

Question 13

What is the difference between anaerobic respiration and aerobic respiration?

Answer 13

Aerobic respiration occurs with oxygen and releases more energy slowly but anaerobic respiration occurs without oxygen and releases less energy but quickly.

Question 14

What do cells need to survive?

Answer 14

Glucose, water, oxygen and amino acids.

Question 15

What does the nucleus do?

Answer 15

This controls the activities of the cell.

Question 16

What does anaerobic respiration produce in microorganisms?

Answer 16

Carbon dioxide and ethanol.

Question 17

Give two examples of unicellular organisms.

Answer 17

Euglena and Amoeba.

Question 18

Put organ systems, organs, cells, tissues and organisms in order of size.

Answer 18

Cells –> tissues –> organs –> organ systems –> organisms –>

Question 19

What substances move into our out of cell by diffusion?

Answer 19

Glucose or oxygen.

Question 20

What is respiration?

Answer 20

The process of releasing energy from glucose.

Question 21

what does anaerobic respiration produce in humans

Answer 21

Lactic acid.

Question 22

What is the cytoplasm?

Answer 22

The gelatinous liquid where most chemical reactions happen.

Question 23

What is a unicellular organism?

Answer 23

A single celled organism.

Question 24

What does a group of organs come together to make?

Answer 24

An organ system.

Question 25

What happens in aerobic respiration?

Answer 25

Glucose and oxygen react to produce carbon dioxide and water.

Question 26

What do you do after you clip a slide onto the stage

Answer 26

Select the lowest powered objective lens.

Question 27

What do you do after you select the lowest powered objective lense?

Answer 27

Turn the rough focusing knob to move the objective lens down to just above the slide.

Question 28

What does a group of similar cells come together to make?

Answer 28

Tissue

Question 29

What does respiration do for the cell?

Answer 29

It releases energy for the cell.

Question 30

How can cells be seen?

Answer 30

Through a microscope.

Question 31

What is the vacuole?

Answer 31

A structure in the cell filled with cell sap that can hold food for later use.

Question 32

What does a group of similar cells make?

Answer 32

A tissue.

Question 33

How can you help to make the cell more visible through a microscope.

Answer 33

By staining it using a coloured dye.

Question 34

Where does aerobic respiration take place?

Answer 34

In the mitcochondria.

Question 35

What part of the microscope do you clip the side to?

Answer 35

The stage

Question 36

What is the use of a microscope?

Answer 36

For looking at objects that can't be seen with the naked eye.

Question 37

What does a plant cell have that an animal cell does no have?

Answer 37

Cell wall, chloroplasts and vacuole.

Question 38

What do you do if you need to see the slide with greater magnification?

Answer 38

Switch to a higher powered objective lens.

Question 39

Where do you carry the microscope by?

Answer 39

Handle

Question 40

What should you always do with the rough focusing knob?

Answer 40

Always turn the rough focusing knob so that the objective lense is moving away from the slide - so the lens and slide dont crash together.

Question 41

What is diffusion?

Answer 41

Where a substance moves from an area of high concentration to an area of low concentration.

Question 42

What is the mitochondria?

Answer 42

The tiny structures in the cell where most reactions for aerobic respiration take place.

Question 43

What does a group of different tissues make?

Answer 43

An organ.

Question 44

What is the cell wall?

Answer 44

A rigid outer coating made of cellulose that gives support to the cell.

Question 45

Explain chloroplasts.

Answer 45

They contain chlorophyll used for photosynthesis. Photosynthesis makes food for the plant.

Question 46

Name 8 parts of a microscope.

Answer 46

Mirror, stage, handle, eyepiece lens, rough focusing knob, fine focusing knob, body tube, high and low power objective lense

Question 47

What is it called when anaerobic respiration produces ethanol?

Answer 47

Fermentation.
