Biology Cell Study Guide
Cell Theory
1.All living things are made of cells
2.Cells are made form other cells
3. Cells are the basic STRUCTURAL and FUNCTIONAL units of life
Robert Hooke: discovered cells while looking at cork using a microscope
Schleiden: all plants are made of cells
Virchow: Cells come from other Cells
Organelle- structure in a cell that performs a specific function
Nucleolus- dark spot in the nucleus where ribosomes are made
Lysosome- sac of digestive enzymes
Rough ER- covered by ribosomes and sends modified proteins to the Golgi Apparatus
Cell Wall- found outside cell membrane in plant cells and bacteria, provides support and protection
Mitochondria- store energy as ATP
DNA- molecule used to store genetic information
Eukaryote- an organism with nuclear membrane and organelles surrounded by membranes
Nucleus- surrounded by double membrane, contains the cells DNA, acts a control center
Flagella- One or two long, hair like structures, help the cell move
Cytoplasm- holds cells organelles
Smooth ER: Several Functions 1. Calcium levels in muscle cells 2. Toxins in liver cells 3. Cholesterol- make 4. Hormone- in ovaries and testes
Cristae- folded layers in mitochondria * Cell membrane is a lipid bilayer
Plasma Membrane- surrounds all cells and is selectively permeable
Ribosomes- makes proteins
* Smooth ER does not have ribosomes attached; Rough ER does * Phospholipids combine with proteins to make cell membranes
Golgi Body- packages molecules for transport out of the cell
Vacuole- space for storing food, water, enzymes, or waste
Prokaryote- organism like bacteria with NO NUCLEUR MEMBRANE AND NO MEMBRANE BOUND ORGANELLES
Cilia- many hair like structures on the surface of a cell that help it move
Centrioles- pull cells apart in cell division
Cytolysis- process by which a cell destroys itself for the good the organism
* If there are a
