In ________ processes, the cell provides energy in the form of ATP to power the transport process.

Active process

What organelles are responsible for providing the most ATP that the cell needs, often referred to as the "powerhouses" of the cell?

Mitochondria

In ___________, parts of the plasma membrane and cytoplasm extend and engulf a relatively large or solid material.

Phagocytosis

The plasma membrane not only provides a protective boundary for the cell but also determines which substances enter or exit the cell. We call this characteristic: A) diffusion B) membrane potiential C) osomosis D) selective permeability

Selective permeability

Which of the following would require an input of energy?

Vesicular transport

True or False: The end product of mitosis is four genetically identical daughter nuclei.

false

A solution surrounding a cell is hypertonic if:

it contains more nonpenetrating solute particles than the interior of the cell

When a cell is not dividing, the DNA is loosely spread throughout the nucleus in a threadlike form called: A) Chromatin B) Chromosomes C) Cytosol D) Ribosomes

Chromatin

A passive process, __________ is the movement of solute molecules from an area of greater concentration to an area of lesser concentration.

Diffusion

When does DNA replication occur?

Interphase
