Proteins that span the entire membrane and create a channel for solutes and molecules to move in and out of the cell are called _________________.

A _____________ is a distinct central organelle that contains the cell's genetic material in the form of DNA.

The semi-fluid environment inside of the cell, which all of the organelles "float" in, is known as the __________________.

The ___________ is a network of long, thin protein fibers that form a framework of support for the cell.

The organelles that help make proteins are ___________.

Ribosomes are produced inside the ______________, which is found inside of the nucleus.

The _________________ is a flattened stack of membranes that modifies, sorts, and packages proteins.

A __________ is a sac used to store food, water, and other materials needed by the cell. (Hint: this organelle is larger in a plant cell than in an animal cell).

________ are vesicles that contain substances that digest waste, including old worn out organelles or food particles.

The organelle that generates the energy for the cell is the __________.

____________ are organelles that capture solar energy and convert it to chemical energy through a process called photosynthesis.

The _____________ is a thick and rigid mess of fibers that surrounds the plasma membrane and protects the cell. (HINT: Plant cells have this and animal cells don't)

The net movement of particles from areas of high concentration to areas of low concentration is called ____________.

The diffusion of water across a selectively permeable membrane is _______________.

The movement of particles across a concentration gradient requires energy; therefore it is called __________________.

___________ is the process by which a cell surrounds a substance outside of the environment, enclosing it in the membrane.

____________ is a secretion of materials at the plasma membrane.
