What is a VACUOLE?
A membrane bound cavity within a cell, holding watery liquid
What is a LYSOSOME?
A cell organelle containing enzymes that digest particles and disinigrate the cell after it dies.
What is a RIBOSOME?
A particle composed of "RNA" and proteins, thats serves as the asembly of polypeptides.
What is a GOLGI COMPLEX?
A complex of parelell saccules, vesilles, and vacuoles that is adjustant to the nucleus.
What is a CYTOPLASM?
A Protoplasm outside the nucleus of a cell.
What is a NUCLEUS?
A mass of protoplasms encased in the membrane that directs.
What is a NUCLEOLUS?
A rounded body withing the nucleus of a cell.
What is a CELL MEMBRANE?
The membrane enclosing the cytoplasm of a cell.
What is a MITOCHONDRIA?
A Organelle in the cytoplasm that contains genetic material.
What is a CENTRIOLE?
A small organell that divides in a perpindicular fashion during mitosis.
What is ROUGH ENDOPLASMIC RETICULUM?
A network of membranes invlolved with transporting materials.
What is SMOOTH ENDOPLASMIC RETICULUM?
A network of membranes with a smooth surface.
What is a CELL WALL?
The definate boundry or wall that is of the outer structure of a plant, protecting it.
What is a CHLOROPLAST?
A plasid containting chlorophyll. (Found in GREEN plant cells)
What is TISSUE?
Its a group of cells that carry out a specific function.
What is an ORGAN?
Is several types of body tissue that together perform a function.
VASCULAR TISSUE SYSTEM
That transports water throughout the plant.
A CELL MEMBRANE (Selectively Premable)
Only allows some substances to pass through
A CELL MEMBRANE (Sluid Mosaic Model)
Lipid bilayer with proteins that move through it.
Function of Mitochondria
Release energy from food. "POWERHOUSE" of the cell
Function of Ribosomes
Where proteins are made
Function of ER
"SUBWAY SYSTEM"
Function of Rough ER
Transports Protein
Function of Smooth ER
Transports Lipids
Function of Golgi Apperatus
Processes and Packages products of ER
Function of Lysosome
Contains strong digestive enzymes; "CLEAN UP CREW" (Not in plant cells)
Function of Cytoskeleton
Network of proteins strand to help with shape and support and MICROTUBULES are BIG and help with cell division.
Function of Cilia
Short; Hair like extension of the cell surface; moves cells
Function of Flagella
Long and whip-like; moves cells.
Function of a Nucleus
Controlls cell activities; the "BRAIN" of cells.
Nuclear Envelope
Surrounds the Nucleus
Chromosomes
Contains "DNA"
Function of a Nucleous
Makes Ribosomes
Plasid Stores:
STARCH
What happens in CHLOROPLAST?
photosynthesis

Cells
2nd Level
Tissues; cells working together; Ex. muscle tissue, nerve tissue, connective tissue, blood, etc.
3rd Level
Organ; Organs working together; Ex. hands, sense, organs, brain, heart, etc.
4th Level
Organ System; Organs working together; Ex. Repitory, circulatory, reproductive, nevers, etc.
Colonial Organisms
A collection of geneticly identical cells that give together; Ex. Volvox: has no tissues or organs but has a cell specialization
Cell Theory #1
All living things are composed of one or more cells
Cell Theory #2
Cells are the basic units of structure and function in an organism
Cell Theory #3
Cells come only from the reproduction of existing cells.
Prokaryotes
Unicellular organism that lack a membrane bound nucleus and orhter organells
Eukaryote
Organisms whose cells contain a membrane bount nucleus and other organelles.
Peripheral Proteins
Are located on both the interioir surface and exterior surface of the cell membrane.
Integral Proteins
Proteins that are embedded in the bilayer.
