Cells

Question 1

Prokaryotic cell

Answer 1

Are single cells-celled organisms. They are simple structures and do not have a nucleus or any membrane bound organelles.

Question 2

Eukaryotic cell

Answer 2

These make up multi cellular organisms such as plants and animals. They are complex cells with a nucleus and membrane-bound organelles. 10 to 100 micrometers.

Question 3

Nucleolus

Answer 3

It makes RNA and ribosomes.

Question 4

Rough Endoplasmic Reticulum

Answer 4

Protein synthesis takes place in the ribosomes and the newly synthesised proteins are transported to the Golgi apparatus.

Question 5

Smooth Endoplasmic Reticulum

Answer 5

Responsible for synthesis and transport of lipids and carbohydrates.

Question 6

Golgi Apparatus

Answer 6

Newly made proteins are received here from the rough ER. The Golgi apparatus modifies them and then packages the proteins into vesicles to be transported to where they are needed.

Question 7

Tonoplast

Answer 7

Selectively permeable to allow small molecules to pass through the vacuole.

Question 8

Amyloplast

Answer 8

Responsible for the synthesis and storage of starch granules.

Question 9

Nucleoid

Answer 9

It is the region where genetic information can be found and controls cellular activity.

Question 10

Plasmid

Answer 10

They carry genes that may benefit the survival of the organism.

Question 11

lysosomes

Answer 11

They break down waste materials including old materials.

Question 12

Vesicles

Answer 12

they are used to transport materials inside the cell and secretory vesicles transport proteins that are to be released from the cell to the surface of the membrane.

Question 13

Pits

Answer 13

Allow water to enter and leave the xylem vessels

Question 14

Plasmodesmata

Answer 14

Enable to transport and communication between individual plant cells
