Cell organelle vocabulary, Holt Biology Chapter 7, Cell Structure.

Cell

A membrane bound structure that is the basic unit of life

Cell Membrane

The lipid bilayer that forms the outer boundary of the cell

Cell Theory

This says that 1. all living things are made of cells, 2. cells are the basic unit of structure and function and 3. cells only come from other cells.

Cell wall

A rigid structure that surrounds the cells of plants and most bacteria

Cytoplasm

The region of the cell between the cell membrane and the nucleus

Cytoskeleton

A network of long protein strands in the cytosol that helps support the cell

Eukaryote

A cell that contains a nucleus and membrane bound organelles

Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Lysosomes

An organelle containing digestive enzymes,

Mitochondria

powerhouse of the cell, produces energy (ATP) from oxygen and sugar(Cellular respiration)

Nuclear envelope

A double membrane that surrounds the nucleus in the cell

Nucleolus

The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus

Nucleus

The organelle that contains the DNA and controls the processes of the cell

Organelle

One of several bodies with a specialized function that is suspended in the cytosol of the cell

prokaryote

A unicellular organism that lacks a nucleus and membrane bound organelles

Ribosome

An organelle that functions in the synthesis of proteins

Vacuole

stores water and nutrients for the cell; very large in plant cells

vesicle

A membrane bound sac that contains materials involved in transport of the cell.

Endoplasmic Reticulum

an internal membrane system in which components of cell membrane and some proteins are constructed

Rough ER

That portion of the endoplasmic reticulum studded with ribosomes.

Smooth ER

That portion of the endoplasmic reticulum that is free of ribosomes.

flagella

whiplike tails found in one-celled organisms to aid in movement

pili

allow prokaryotes to attach to surfaces and to each other and allows them to transfer DNA.
