Question 1

Do animal cells have a regular or irregular shape?

Answer 1

Irregular

Question 2

Does a plant cell have a regular or irregular shape?

Answer 2

Regular

Question 3

Structures in an animal cell:

Answer 3

• cytoplasm
• vesicle
• ribosome
• nucleus
• chromatin
  -nucleolus
• Golgi apparatus
• mitochondrion
• Rough endoplasmic recticulum
• plasma membrane

Question 4

Function of plasmodesma?

Answer 4

It allows cell-to-cell transport and communication, from the cytoplasm of once cell to another

Question 5

Function of a cell wall?

Answer 5

To support the cell. It gives the cell structure which prevents it from changing shape

Question 6

Function of chloroplast?

Answer 6

Converts light energy into chemical energy stored in organic compound such as sugars

Question 7

Function of rough endoplasmic reticulum?

Answer 7

To produce proteins for the rest of the cell to functioned, contains ribosomes on it

Question 8

Function of cytoplasm?

Answer 8

Maintains optimum environment in the cell. Helps to move materials e.g. hormones around the cell and dissolves cellular waste

Question 9

Function of vesicle?

Answer 9

Organises cellular substances. Involved in metabolism, transport buoyancy control and enzyme storage, acts as a chemical reaction chambers

Question 10

Function of ribosome?

Answer 10

Receives genetic information from DNA. In the form or messenger RNA , reads it and uses the instructions stored in it to make proteins

Question 11

Function of chromatin?

Answer 11

Package DNA. Into a smaller volume to fit in the cell strengthen the DNA. To allow mitosis and meiosis, and serve as a mechanism to control expression

Question 12

Function of nucleolus?

Answer 12

To produce and assemble the cells ribosomes, and where ribosomal RNA genes are transcribed

Question 13

Function of Golgi apparatus?

Answer 13

Transporting, modifying and packaging proteins and lipids into vesicles for delivery to targeted destinations

Question 14

Function of mitochondrion?

Answer 14

Produce energy through cellular respiration

Question 15

Function of plasma membrane?

Answer 15

Provides protection for a cell and to transport nutrients into the cell and toxic chemicals out the cell

Question 16

Function of a vacuole?

Answer 16

Helps maintain pressure in a plant cell, by pushing cytoplasm against the ell wall, which keeps the plant ell turgid and prevents wilting

Question 17

Structures of a plant cell that are not in a animal cell?

Answer 17

• vacuole
• chloroplast
• cytoplasm
• cell wall

Question 18

Why are enzymes only needed in small amounts by cells?

Answer 18

They can be reused

Question 19

Why are enzymes specific fro a particular substrate?

Answer 19

The shape of the substance fits exactly into the active site like a lock and key

Question 20

What are the bases in DNA?

Answer 20

• guanine
• cytosine
• thymine
• adenine

Question 21

Insulin is an example of…

Answer 21

Protein

Question 22

An example of a structural protein found in the skin is?

Answer 22

Collagen

Question 23

If a plant cell is placed in a concentrated sugar solution what would happen?

Answer 23

Water will diffuse out of the cell cytoplasm by osmosis
