Cells and Cell Function

Front

What occurs during interphase in the cell cycle?

Back

During interphase, cells grow, duplicate their DNA, and prepare for division.

Front

What is exocytosis?

Back

Exocytosis is a form of active transport that involves the movement of materials out of a cell.

Front

What is the main component of the plasma membrane?

Back

The main component of the plasma membrane is lipid.

Front

What is passive transport?

Back

Passive transport is the movement of particles from high to low concentration without the use of energy.

Front

What stage of mitosis is characterized by the alignment of chromosomes at the cell's equator?

Back

Metaphase is the stage of mitosis where chromosomes align at the cell's equator.

Front

What is the function of the plasma membrane?

Back

The plasma membrane regulates what enters and exits the cell, providing protection and support.

Front

Define active transport.

Back

Active transport is the movement of substances across a cell membrane against their concentration gradient, requiring energy.

Front

What are the two main types of transport across cell membranes?

Back

The two main types of transport are passive transport and active transport.

Front

What is the role of DNA during interphase?

Back

During interphase, DNA is replicated to ensure that each daughter cell receives an identical set of chromosomes.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy and moves substances down their concentration gradient, while active transport requires energy to move substances against their gradient.
