Cytoplasm

Question 1

What is the cytoplasm?

Answer 1

The cytoplasm is the cellular material between the plasma membrane and the nucleus.

Question 2

What are the three elements in the cytoplasm that are revealed by the electron microscope?

Answer 2

Cytosol, Inclusions and organelles

Question 3

What is they cytosol made up of?

Answer 3

Cytosol is largely made up of water and contains proteins, salts, sugars, amino acids, and other molecules that suspend all other cytoplasmic elements.

Question 4

What are the inclusions in cytoplasm?

Answer 4

Inclusions are non-functional chemical substances that may or may not be present in the cytoplasm. Examples include stored sugars called “glycosomes,” lipid droplets, and melanin granules.

Question 5

Name examples of inclusions in the cytoplasm.

Answer 5

Examples include stored sugars called “glycosomes,” lipid droplets, and melanin granules.

Question 6

What are organelles and what is their function?

Answer 6

Organelles are the metabolic machinery of the cell and each has a specific function. Most organelles are membranous, but some are non-membranous, such as the cytoskeleton, centrioles, and ribosomes.

Question 7

What is the difference between membranous and non-membranous organelles?

Answer 7

Membranous organelles have a cell membrane similar to the plasma membrane but lacking glycolax.
