|
Cell Membrane
|
Two layers of phospholipids with proteins randomly embedded in it. Selectively permeable. Controls the transport of materials in and out of the cell. Functions in recognition, communication, and hoeostasis.
|
|
|
Mitochondria
|
Large double membrane bound organelle. Made up of the Matrix and Cristae. Site of cellular respiration. Breaks down organic materials to produce energy in the form of ATP
|
|
|
Smooth Endoplasmic Reticulum
|
Membraneous tubular canals, that start outside of the nucleus and branch through the cytoplasm. Allow an increased surface area for chemical reactions. Creates lipids, phospholipids, and cholesterol. Detoxifies drugs, and chemicals in the cell.
|
|
|
Rough Endoplasmic Reticulum
|
Membraneous tubular canals. Make protein for cell. Transporation of protein.
|
|
|
Ribosomes
|
Small organelles made of RNA and protein. Not covered by a membrane. Two main subunits made in nucleus then sent to cytoplasm. Site of protein synthesis. Free in cytoplasm - makes protein for the cell. On ER - makes protein to be exported out of the cell.
|
|
|
Golgi Bodies/Golgi apparatus
|
stacks of flattened hollow cavities enclosed by membranes. Modification, assemply, packaging, storage, and secretion of substances ex.protein
|
|
|
Vesicles
|
Small membrane-bound sac. Stores substances within a cell. Used for transportation and storage of materials.
|
|
|
Vacuoles
|
Membrane bound sac. Holds fluid and other substances. May store food, wastes, etc.
|
|
|
Lysosomes
|
Special vesicle formed by Golgi app. Contains powerful hydrolytic enzymes. Functions in cellular digestion of food, auto-digestion of damaged cell parts and sometimes breaking down a whole cell.
|
|
|
Nuclear envelope/membrane
|
double membrane surrounding nucleus that has nuclear pores allowing substances to pass through or out of the nucleus. Continuous with the ER.
|
|
|
Nucleus
|
large organelle surrounded by a double membrane. Contains DNA and is the site of making RNA
|
|
|
Nucleolus
|
Dark-staining structure. Densley packed chromosomes, or loose chromatin. Site of RNA synthesis.
|
|
|
Chromosomes
|
Rodliek structure in the nucleus. Made up of genes that are made up of DNA. Carries genetic code.
|
|
|
Cell Wall
|
stiff structure that surrounds a plant, protistan, fungal, bacterial cell. Made of cellulose. Maintains cell shape and rigidity. Prevents structure from burstin
|
|
|
Chloroplast
|
large, double-membrane bound organelle. Found only in plant cells. Produce food for plant cells through photosynthesis
|
|
|
Cytoskeleton
|
Network of microtubes and microfilaments. Help cell maintain shape, anchor organelles, or help organelles move.
|
|
|
Cytoplasm
|
Semi-fluid medium, Contains organelles.
|
|
|
Nuclear Pore
|
Opening in nuclear envelope. Permits passage of proteins into the nucleus and ribosomal units out
|
|
|
Chromatin
|
Network of Fibrils. Consist of DNA and proteins. In this frm when nucleus isn't dividing.
|
|
|
Cristae
|
Short fingerlike projections formed by folding of inner membrane of Mitochondria. Helps create ATP
|
|
|
Matrix
|
Breaks down glucose.
|
