Cell Biology Flashcards Flashcards

A cell with a nucleus and membrane-bound organelles, such as animal and plant cells.

A smaller, simpler cell without a nucleus, such as bacterial cells.

sub-cellular structure that contains genetic material and controls the activities of the cell.

Organelles where aerobic respiration occurs, providing energy for the cell.

A structure in plant cells that contains chlorophyll and is site of photosynthesis.

A sub-cellular structure where protein synthesis occurs.

A small, circular piece of DNA found in bacterial cells.

The process by which cells develop specific structures and functions to perform particular roles.

Has a tail for movement, many mitochondria for energy, and enzymes in the head to penetrate the egg.

The use of microscopes to view small structures, including light and electron microscopes.

A microscope with higher magnification resolution than a light microscope, allowing detailed views of sub-cellular structures.

Magnification = size of image / size of real object.

The movement of particles from an area of high concentration to an area of low concentration.

The movement of substances against a concentration gradient, requiring energy from respiration.
