Cells & Cell membrane
What type of cell is characterized by having plasmid DNA and a simple cell structure without compartments.
What is a prokaryote?
The spreading out of particles in liquids and gases that happens because the particles are in continuous random motion.
What is diffusion?
The division of the nucleus into 2 genetically identical daughter nuclei.
What is mitosis?
This property is useful in leaves, where water sticks to cellulose molecules in cell walls.
What is adhesion?
These can be saturated, monounsaturated or polyunsaturated.
What are fatty acids?
Surface area to volume ratio is important in the limitation of this.
What is cell size?
The fluidity of membranes that allows materials to be taken into cells.
What is endocytosis?
The ratio between the number of cells in mitosis in a tissue and the total number of observed cells.
What is the mitotic index?
Positive ions and negative ions attract each other and form this type of bond.
What is ionic?
This type of chart allows you to find a person's BMI.
What is a nomogram?
Phospholipids are unusual because part of a phospholipid molecule is hydrophobic and hydrophilic.
What is amphipathic?
This is due to differences in the concentration of substances dissolved in water.
What is osmosis?
Proteins that control the cell cycle.
What are cyclins?
When a molecule evaporates it separates from other molecules in a liquid and becomes a vapor molecule.
What is high latent heat of vaporization?
Triglycerides are formed by this type of reaction.
These biomolecules are diverse in terms of structure, their position in the membrane and their function.
What are proteins?
This type of cell transport is carried out by globular proteins in membranes by pump proteins.
What is active transport?
When the cleavage furrow reaches the center and the the cell is pinched apart into 2 daughter cells.
What is cytokinesis?
What is a covalent bond?
What is a lipid?
What is cholesterol?
What is the Golgi apparatus?
Condensation occurs by means of repeatedly coiling the DNA molecule to make the chromosome shorter and wider.
What is supercoiling?
The type of bond that creates the attraction between water molecules.
What is a hydrogen bond?
These are produced artificially by partial hydrogenation of vegetable or fish oils.
What are trans-fatty acids?
