Cell Structure
Lysosomes
An organelle containing digestive enzymes,
Ribosome
An organelle that functions in the synthesis of proteins
Eukaryote
A cell that contains a nucleus and membrane bound organelles
Nuclear envelope
A double membrane that surrounds the nucleus in the cell
vesicle
A membrane bound sac that contains materials involved in transport of the cell.
Cell
A membrane bound structure that is the basic unit of life
Cytoskeleton
A network of long protein strands in the cytosol that helps support the cell
Cell wall
A rigid structure that surrounds the cells of plants and most bacteria
Golgi apparatus
A system of membranes that modifies and packages proteins for export by the cell
prokaryote
A unicellular organism that lacks a nucleus and membrane bound organelles
Organelle
One of several bodies with a specialized function that is suspended in the cytosol of the cell
Rough ER
That portion of the endoplasmic reticulum studded with ribosomes.
Smooth ER
That portion of the endoplasmic reticulum that is free of ribosomes.
Cell Membrane
The lipid bilayer that forms the outer boundary of the cell
Nucleus
The organelle that contains the DNA and controls the processes of the cell
Nucleolus
The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
Cytoplasm
The region of the cell between the cell membrane and the nucleus
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.
pili
allow prokaryotes to attach to surfaces and to each other and allows them to transfer DNA.
Endoplasmic Reticulum
an internal membrane system in which components of cell membrane and some proteins are constructed
Mitochondria
powerhouse of the cell, produces energy (ATP) from oxygen and sugar(Cellular respiration)
Vacuole
stores water and nutrients for the cell; very large in plant cells
flagella
whiplike tails found in one-celled organisms to aid in movement
