Eukaryotic Cell Project
Terms in this set (20)
contains genetic material: DNA - deoxyribonucleic acid, RNA - ribonucleic acid. Function -controls protein synthesis.
DNA plus a special proteins called histones.
condensed chromatin. Look like an X.
RNA is manufactured here.
made up of lipid bilayer, surrounds the nucleus, keeps the DNA safe inside.
Smooth Endoplasmic Reticulum
does not have ribosomes. Function is the synthesis of lipids, phospholipids and steroids (cholesterol), storage of calcium, liver detoxifying dangerous chemicals.
Rough Endoplasmic Reticulum
does have ribosomes. Function - modify proteins - usually adding sugars to it to turn it into a glycoprotein. Then the molecule is put into a transport vesicle.
flattened pancakes. Function - warehouse and finishing factory. Any final modifications are made to the glycoproteins for external shipment out of the cell.
free - found in the cytoplasm, Rough ER - has ribosomes embedded within the structure. Make proteins, received instructions from the nucleus. DNA ---> RNA ----->Ribosomes -----> decode the RNA and make the protein.
membrane bound, contain strong chemicals that are released when a cell is worn out and needs to be destroyed. "Suicide sac".
hold hydrogen peroxide. Diseases associated with lysosomes. Pompe's disease, Tay-Sachs (EC)
H2O2 is toxic to cells, transports the H2O2 to the liver cells where catalase will break it down into water & oxygen.
storage, plants it is large in size. Animals usually small in size - called a vesicle. Contractile vacuole (EC)
where cellular respiration occurs - energy. Place where glucose goes to get broken down to provide the cell with energy. EC is mitochondrial disease.
(Plants) where photosynthesis takes place.
Cytoplasm - cytoskeleton
gives the cell its shape, aids in movement, transmits signals from inside the cell to the outside. EC microfilaments (solid), microtubules (hollow), intermediate filaments (rope like).
tiny hair like projections that aid in cell movement,
tail, whip like, aids in movement - sperm
found in pairs, located near the nucleus aid in cell division or mitosis.
border around the cell, controls what enters and exits the cell, made up of a lipid bilayer.
found only in plants and bacteria, extra protection and support.
