7.2 Cell Structure

ribsomes

the productions of proteins are some of the most important roles in a cell. These proteins are formed on Ribosomes that are found throughout the cytoplasm. Ribosomes produce proteins based on instructions given by the nucleus.

organelles

A specialized structure within a cell, such as a mitochondrion, vacuole, or chloroplast, that performs a specific function. Organelles literally means "little organ" because it's a tiny organ that performs a specific task in the body.

endoplasmic recticulum

A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids.

golgi apparatus

An organelle in eukaryotic cells consisting of stacks of flat membranous sacs that modify, store, and route products of the endoplasmic reticulum such as proteins.

centrioles

Centrioles are located near the nucleas and are responsible for the division of the cells. Centrioles are not present in plant cells.

Mitochondria

Convert the chemical energy stored in food into compounds more convenient for the cell to use

Chloroplast

Converts energy from the sunlight to food for the the cell to keep on function.

cytoplasm

The cytoplasm is the part of the cell that is outside the nucleus. Cytoplasm is present in Eukaryotic as well Prokaryotic cells even though prokaryotic cells do not have a nucleus.

cytoskeleton

The cytoskeleton is like support structure of the cell. It maintains movement of the substances in the cell. Some cytoskeletons even move the entire cell.

the nucleus

The nucleus is like the control center of a eukaryotic cell. It contains all or the cells genetic information and the instructions for making proteins or other molecules. This is not present in prokaryotic cells.

vacuoles

Vacuoles are sort of like the storage silos of the cell. The hold molecules like water, salts, proteins and other molecules. In plant cells, the is one large vacuole filled with liquids.
