Front

What are the two parts of a phospholipid?

Back

Hydrophilic Head and Hydrophobic Tail.

Front

What organelle is responsible for cell digestion?

Back

Lysosomes.

Front

What is the hydrophilic portion of the cell membrane?

Back

The part of the membrane that interacts with water, typically the heads of phospholipids.

Front

Where are ribosomes produced in the cell?

Back

Nucleolus.

Front

How does rinsing swollen gums with warm salt water help?

Back

Water in the gums will diffuse out of the cells.

Front

What is the function of lysosomes in a cell?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

Define hydrophilic. Give an example.

Back

Hydrophilic means 'water-loving.' An example is the phosphate head of a phospholipid.

Front

Define hydrophobic. Give an example.

Back

Hydrophobic means 'water-fearing.' An example is the fatty acid tails of a phospholipid.

Front

What is the role of the Golgi apparatus in a cell?

Back

The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the structure and function of the endoplasmic reticulum (ER)?

Back

The ER is a network of membranes involved in protein and lipid synthesis; it comes in two forms: rough (with ribosomes) and smooth (without ribosomes).
