Cell Bio - Cell Structure

Question 1

• Role of the NUCLEUS?
• Role of the PLASMID?

Answer 1

• Contains DNA in animal, plant and fungal cells to control cell activities
• Small ring of genetic material found in bacterial cells.

Question 2

• Role of the CELL MEMBRANE?
• Role of the CYTOPLASM?

Answer 2

• Selectively permeable membrane that controls the entry and exit of substances such as oxygen, carbon dioxide, glucose and waste to and from cells.
• Stores the cell organelles and it is the site of chemical reactions.

Question 3

• Role of the CELL WALL?
• Role of the RIBOSOMES?

Answer 3

• Outer layer that provides support and protection to plant, fungal and bacterial cells by giving them a rigid structure that prevents them from bursting.
• Site of protein synthesis

Question 4

Role of the VACUOLE?

Answer 4

Membrane-bound sac that store a solution of water, salts and sugars (cell sap) and helps support plant and fungal cells.

Question 4

• Role of the MITOCHODRIA/ION?
• Role of the CHLOROPLASTS?

Answer 4

• Main site of ATP (adenosine triphosphate) production in aerobic respiration in animal, plant and fungal cells.
• Makes carbohydrates in green plant cells using light energy in the process of photosynthesis.

Question 5

• What is a prokaryotic cell?
• What is a eukaryotic cell?

Answer 5

• Single-cell organism without a nucleus and other membrane-bound organelles
• Complex cells containing a nucleus and other membrane-bound organelles.
