30 Cards in this Set

  • Front
  • Back
DNA
Deoxyribonucleic acid, genetic material found in the nucleus
Nuclear Membrane or Envelope
double membrane surrounding the nucleus,covered with pores (fluid between membranes)
Nuclear Pores
penetrate through the fused portion of nuclear membrane selectively permeable but passage freer d/t large pores
Nucleoplasm
jelly like substance in which other nuclear elements are suspended
Nucleoli
(little nuclei)round bodies where ribosomes are assembled,
Chromatin/Chromosomes
Cromatin bumpy threads in nucleus that form the chromosomes during dividing
Plasma Membrane
transparent membrane that contain the cells content
Phospholipids
the basic fabric of the plasma membrane lollipop shaped,head hydrophilic,tail hydrophobic
Microvilli
tiny fingerlike projections that increase cell surface area for absorption
Cytoplasm
the cellular material outside the nucleus and inside the plasma membrane
Organalles
(little organs)the metabolic machinary of the cell
Mitachondria
sausage shaped organalle, contains enzymes that break down food to form energy (ATP)
Ribosomes
tiny, dark bodies made of protiens acual site of protien synthesis
Rough endoplasmic reticulum
or Rough ER
Studded with ribosomes protiens are formed into 3 dimentional shapes & sent to other parts of cell in vesicles
Smooth endoplasmic reticulum or Smooth ER
fonctions in lipid metabolism,abundant in liver cell and body cells that produce hormones
Gogli Apparatus
Traffic director for cellular protiens sent to plasma membrane in vesicle, attach to plasma membrane and ejected to the out side of cell
Lysomes
Membanous sacs containing digestive enzymes that digest worn out or non usable cell structures
Paroxisomes/paroxide bodies
membranous sacs containing oxidase enzymes that use molecular O2 to detoxify harmful or poisonous substances
Cytoskeleton
elaborate network of protien structures in the cytoplasm that form the "bones&muscles" of the cell
Centrioles
durring cell division direct the formation of the miotic spindles
Flagella
the only example of a flagellated cell in the human body is male sperm refering to the tail
Cilia
whisperlike cellular extentions that move substances along the cell surface
Cells that connect body parts
fibroblasts, erythrocytes
cells that move organs and body parts
Skeletal muscle cells, smooth muscle cells
Cells that cover and line body organs
epithelial cells
cells that store nutrients
fat cells
Cells that fight diseases
Macrophage
cells that gather information and control body function
Nerve cells
cells of reproduction
Sperm(male) Oocyte(female)
ATP
Adenosine triphosphate it provides a form of chemical enery that is usable by all body cells
