Plant And Animal Cells

Question 1

Magnification = ?

Answer 1

Actual length

Question 2

Actual size = ?

Answer 2

Magnification

Question 3

The presence of the cellulose cell wall in plant cells mean that they are very:

Answer 3

Regular in shape.

Question 4

The presence of the vacuole means that plant cells may be:

Answer 4

Quite large.

Question 5

Plant cell features often relate too:

Answer 5

Autotrophic nutrition.

Question 6

What does the large, permanent vacuole in the plant cell do?

Answer 6

Contains water nessecary to provide turgor pressure. They may also store ions and molecules.

Question 7

Where is starch stored in a plant cell?

Answer 7

In the cytoplasm or the chloroplasts.

Question 8

What is starch?

Answer 8

The storage form of carbohydrates.

Question 9

What do chloroplasts contain?

Answer 9

Chlorophyll and the enzymes necessary for the production of glucose by photosynthesis.

Question 10

What is chlorophyll?

Answer 10

A pigment in chloroplasts that absorbs light.

Question 11

What is special about a plant cells wall?

Answer 11

It is freely permeable to water and dissolved substances.

Question 12

What are some of the functions of the cell wall?

Answer 12

It provides structural support and protects against damage caused by osmotic intake of water.

Question 13

What is a plant cell wall made of?

Answer 13

Cellulose!!!

Question 14

The absence of the cellulose wall means that animal cells may be:

Answer 14

Very irregular in shape.

Question 15

The amount of cytoplasm that can be controlled by the nucleus is limited, so animal cells may be:

Answer 15

Quite small.

Question 16

In what form are carbohydrates stored in animal cells?

Answer 16

As glycogen!!!

Question 17

Are animal cell vacuoles permanent?

Answer 17

No. They are small and temporary.

Question 18

What do vacuoles in phagocytes do?

Answer 18

They are involved in digestion.

Question 19

What do contractile vacuoles do?

Answer 19

They are involved in excretion. They remove excess water.

Question 20

What do secretory vesicles do?

Answer 20

They contain cell products such as hormones or enzymes.

Question 21

Are secretory vesicles more common in plant cells or animal cells?

Answer 21

Animal cells 🐾

Question 22

Animal cell features often relate too:

Answer 22

Heterotrophic nutrition and high rates of metabolic activity.

Question 23

What does the nucleus in plant and animal cells contain?

Answer 23

Genetic material!!!

Question 24

What is genetic material?

Answer 24

DNA which makes up genes on the chromosomes.

Question 25

What does the genetic material in these cells do?

Answer 25

It carries coded instructions for controlling the activities and characteristics of the cell.

Question 26

When do chromosomes become visible?

Answer 26

During cell division.

Question 27

What does cell surface membrane in plant and animal cells do?

Answer 27

It controls the entry and exit of dissolved substances and separates the cell’s contents from it’s surroundings.

Question 28

What does the cytoplasm in plant and animal cells contain?

Answer 28

Water and dissolved substances such as sugar and salts.

Question 29

What do large numbers of mitochondria in a cell indicate?

Answer 29

A high rate of metabolism.

Question 30

What happens in organelles?

Answer 30

Chemical reactions!!!

Question 31

What are cells with similar structures and functions called?

Answer 31

Tissues.

Question 32

What is a combination of several tissues sometimes called?

Answer 32

An organ. A good example of this is the small intestine.

Question 33

In complex organisms, several organs work together to perform a particular task. What is this called?

Answer 33

An organ system.
