Section 1

Question Answer
What is a Prokaryotic cell?this cell DOES NOT HAVE STRUCTURES surronded by the MEMBRANE. only FEW INTERNAL STRUCTURES
What is a Eukaryotic cell?CONTAINS ORGANELLES SURRONDED BY THE MEMBRANES. most LIVING organisms are MADE UP OF THESE CELLS
What is the cell membrane?the OUTER membrane of cell that CONTROLS MOVEMENT IN AND OUT of the cell. double LAYER composed of LIPDS, PROTEIN AND CHOLESTEROL. Selectively permeable, only certain materials can pass thru.
what is the cell wall?most commonly FOUND IN PLANT CELLS OR BACTERIA. Supports and protects cells
What is the nucleus?DIRECTS cell activities. SEPERATED FROM CYTOPLASM BY NUCLEAR MEMBRANE. this contains genetic material (DNA) centre of the cell, has chromosones
what is the nuclear membrane?surronds nucleus, made of TWO LAYERS, OPENINGS ALLOW material to enter and leave nucleus.
What are chromosones?in nucleus, contains dna, instructions for traits and characteristics
what is the nucleolus?small sphere inside nucleus. contains RNA to build proteins
what is cytoplasm?is a gel like mixture where all work is done. surronded by cell membrane.
what is smooth endoplasmic reticulum (E.R)?moves materials in cell. lacks Ribosomes, Produces LIPIDS
what is rough endoplasmic reticulum?moves material in cell. Ribosomes embedded in surface, PROTEIN SYNTHESIS
what are ribosomes?each cell contains these. this is INVOLVED IN THE PROCESS OF PROTEIN SYNTHESIS. found on the ER, floating throughout the cell
what is the mitochondriaProduces energy through CHEMICAL REACTIONS. Breaks down FAT and CARBS. The power house of the cell. Creates ATP for cellular function. Only works in presence of Oxygen/nutrients.
Golgi bodies?protein packaging plant. MOVES MATERIALS WITHIN CELL AND OUT OF THE CELL
Lysosome?Digestive 'plant" for PROTEINS FAT AND CARBS. transports undigested material to CELL MEMBRANE for removal
Vacuoles?membrane. Bound sacs FOR STORAGE, DIGESTION and WASTE REMOVAL. contains water solution. helps plant maintain shape
chloroplast?found in PLANT CELLS and NEVER in ANIMAL CELLS. has GREEN CHLOROPHYLL. photosynthesis takes place.
Centrioles?only found in ANIMAL CELLS and some plant cells. key role in cell division. (mitosis) only PRESENT during CELL DIVISION.
what is the function of peroxisome? (both in plant and animal)converts fatty acids to sugars, contains enzymes
what is the function of central vacuole? (plant)storage to hold materials and waste in plants
what is the function of plastids? (plant)storage containers w/ own DNA (chloroplast, amyloplast (starch), leukoplast ( pigmint storage))
what is the function of membrane vacuole? (plant)controls entry and exit of materials into vacuole
what is the of the pinocytotic vesicle? (animal) a way to bring in nutrients into the cell that can't fit through cell membrane
what is the function of a cytoskelton? (animal)protein tubes that provide structure to cells
