Term
Cytoplasm
Definition
The fluid outside of the nucleus in a cell's configuration.
Term
Organelle
Definition
Inside an eukaryotic cell, it is a specialized structure that performs important cellular functions.
Term
Cytoskeleton
Definition
The network of protein filaments in a eukaryotic cell that gives the cell both its' internal and outer organization, and is involved in the cell's movement as well
Term
Centriole
Definition
The structure inside an animal cell that helps to organize cell division.
Term
Ribosome
Definition
A cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the main site of protein synthesis.
Term
Endoplasmic reticulum
Definition
Internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled.
Term
Golgi Apparatus
Definition
A specialized organelle in cells that modifies, sorts, and packages proteins and other materials from the edoplasmic reticulum for storage in the cell or release outside the cell.
Term
Chloroplast
Definition
A specialized organelle found in cells of plants and few other organisms that captures solar energy, converting it into chemical energy for itself.
Term
Mitochondrion
Definition
A specialized cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell's usage.
Term
Cell Wall
Definition
The strong, supporting layer surrounding the cell membrane in some cells.
Term
Lipid Bilayer
Definition
A flexible double-layered sheet, forming a barrier between the cell and it's surroundings.
Term
Selectively Permeable
Definition
The property of biological membranes that allow some substances to pass across it while others cannot; also called semipermeable membrane.
Term
Vacuole
Definition
A specialized cell organelle that stores materials such as proteins, water, and carbohydrates that help the cell function.
Term
Lysosome
Definition
A specialized cell organelle that breaks down lipids, carbohydrates, and proteins (Mainly from vacuoles) into smaller molecules that can be used in the rest of the cell.
