CS - main organelles found in Eukaryotic cells.

Question 1

mitochondria

Answer 1

It is the site of ATP production (provides them to ribosomes) by aerobic cellular respiration to provide a cell with energy. (use of oxygen to break down food molecules).

Question 2

ribosomes

Answer 2

Non-membrane bound organelle made of RNA and protein and it is the site of protein synthesis.

Question 3

nucleus

Answer 3

The organelle that contain DNA - the coded instructions for the synthesis of proteins.

Question 4

chloroplasts

Answer 4

The site of photosynthesis. Independent and dependent stages of photosynthesis.

Question 5

Rough Endoplasmic Recticulum

Answer 5

a large network of intracellular channels that is involved in the transport and modification of the proteins. It is called ‘rough’ because many ribosomes are located on it.

Question 6

Golgi Apparatus

Answer 6

a stack of flattened membrane sacs that are involved in the modification of proteins, and their transport out of the cell by exocytosis.

Question 7

Cell Wall

Answer 7

• a rigid cellulose layer on the outside of a plant cell
• provides resistance to the turgor pressure created by osmosis and the plant structure.
• The cell wall is not actually an organelle.
