Active transport :
It is the transport of a solute across a membrane in the direction of increasing concentration involving the expenditure of energy.
It refers to liquid molecules having both hydrophobic (water hating) and hydrophilic (water loving) ends.
It is the process of self destruction of a cell by the release of lysosomic enzymes in the cell itself.
It is the process by which unwanted substances within the cell are removed.
Basal body :
Centriole structure near the cell membrane from which Cilia and flagella develop. It is also called blepharoplast.
The smallest unit of life having a complex internal structure. The identity of various cellular components and functions of different structures have been studied with the help of electron microscope.
Cell theory :
Doctrine initiated by Theodar Schuann in 1838 that all organisms are made up of cells and their products.
Cell wall :
Semi-rigid permeable structure composed of cellulose lignin etc. that envelopes the plasma membrane in the cell of algae, bacteria, fungi and plants (animal cells have no cell wall).
A complex carbohydrate which consists of a chain of glucose molecules present in the cell wall of plants except fungi.
A minute granular self replicating body from which astral rays and spindle fibres arise forming a spindle during cell division.
A small clear cytoplasmic body containing contriole(s), situated just outside the nuclear membrane in animal cell and helps in spindle formation.
Green pigments of plants which is meant for capturing solar energy of the sun during photosynthesis.
Coloured plastids containing pigments other than chlorophyll.
They are the carriers of heredity units of genes.
(pl. cilla) : Minute hair like protoplasmic process arising from the cell surface.
The folds of inner membrane of mitochondria protecting towards the inner side.
Generation of cytoplasmic current by the action of microfilaments.
Protoplasmic material of cell not including the nucleus and its contents.
Cytoplasmic matrix :
The protein of cell protoplasm not contained within the endomembrane system. It is called cytoplasm.
Complex cytoplasmic network of microtubules and microfilaments located predominantly near the cell membrane and thought to be responsible for shell shape and movement.
Unit of molecular weight, one Dalton equals one twelfth of mass of carbon 12.
Organelle in the plant cell consisting of stacks of membrane sacks and vesicles that enclose and store cell product.
The movement of molecules or ion resulting from their kinetic energy that tends to disperse them throughout the medium.
The differences between electric charges between two sides of membrane.
Endoplasmic reticulum :
A system of channels and tubes in the cytoplasm which functions as site of protein synthesis and transport.
The chromatin that constitutes bulk for the chromosome and contains the active genes.
Facilitated diffusion :
A substance first combines with the carrier protein without use of energy in the cell membrane and then it diffuses across the membrane.
(pl. flagella) Microscopic thread like protoplasmic extension of the cell surface.
Quasi solid state of (colloidal) matter.
A unit of genetic information.
A Polysaccharide related to starch (present mostly in animals) made up of many glucose sub-units and generally acts as a reserved food material.
Golgi body :
A cytoplasmic organelle in the animal cell consisting of a stack of coarse membranes that enclose and store cell products.
Thyalokoids packed like pale of coins.
(pl grana) : Discoid stack of membranes containing chlorophyll.
It is a hybrid cell.
Chromatin rich in RNA responsible for nucleic acid metabolism.
Cytoplasm without cell organelle.
A solution having a higher concentration of solute molecules and a lower concentration of solvent molecules (water) than that of solution to which it is compared.
A solution having a lower concentration of solute molecules and a higher concentration of solvent molecules than that of solution to which it is compared.
Incipient plasmolysis :
The point at which plasmolysis just starts.
A solution having the concentrations of a solute and solvent water molecules exactly equal to that in another solution to which it is compared.
A thin ribbon like structure present in the chloroplast.
A complex organic substance in the wall of woody plants cells that lends strength to them.
Single membranous bag like organelle containing digestive enzymes also called suicidal bag.
Dark coloured pigment in animals found mostly in skins.
Middle lamella :
Layer which holds the neighbouring cells together and is made up of magnesium and calcium pectate.
Principal organelle of eukaryotic cell that is bounded by a membrane. It contains nucleoplasm and chromosomes. Genes present on chromosomes control the structure of proteins within the cell. Most of the cells are uninucleate and few multinucleate.
The process by which a cell or an animal controls the amount of water and the concentrations of various solutes and ions in the body.
Osmotic Pressure :
The force that a dissolved substance exerts (by virtue of motion of its molecules) on a semipermeable membrane through which it cannot pass.
Membrane enclosed organelle containing enzymes for hydrogen peroxide metabolism.
It refers to intake of solid particles by the cell.
Process of engulfment of large sized solid food particles by the cell through the plasma membrane.
A group of fatty compounds composed of phosphoric esters such as lecethin.
Process of intake of a fluid food material by the cell through plasma membrane.
The living membrane surrounding a cell, also referred to as plasma membrane. Physiologically, it is semipermeable.
The shrinkage of protoplasm in cell due to removal of water by exosmosis.
It refers to a cluster of ribosomes connected by common strand of messenger RNA.
A major category of living organisms including algae except (blue green) slime moulds, protozoan fungi.
It refers to a spherical body present in thyalcoid and capable of carrying out photochemical reactions.
