COMPARISON OF PROKARYOTIC & EUKARYOTIC CELL

DIFFERENCE PROKARYOTES EUKARYOTES
 1) CELL TYPE They are composed of prokaryotic cells. They are composed of eukaryotic cells.
 2) NUCLEUS Nucleus is absent in them. They have well defined nucleus.
 3) DNA DNA is without any nuclear membrane covering and is directly submerged in cytoplasm. DNA is enclosed inside the nucleus.
 4) MEMBRANE-BOUNDED STRUCTURES Membrane-bounded structures are absent. Membrane-bounded structures are present.
 5) RIBOSOMES They have small sized 70S ribosomes. They have large sized 80S ribosomes.
 6) CELL WALL Their cell wall is composed of polysaccharide chain covalently bonded with shorter chains of amino acids forming peptidoglycan or murein. Cell wall of plants is generally composed of cellulose.
 7)  CELL DIVISION They reproduce by binary fission. They reproduce by mitosis and meiosis.
 8)  EXAMPLES Bacteria and blue green algae. Multicellular animals and plants are examples.

DISPLACMENT, DISTANCE, SPEED, VELOCITY AND ACCELERATION

Displacement: Shortest distance between two points is called displacement                                                                OR The displacement is a change in the position of body form its initial position to final position Unit:  SI unit of displacement is metre (m)                    Dimension:             The dimension of displacement is [L] VELOCITY: The time rate of change of displacement is known as velocity. It is a vector quantity. Its direction is along the direction of displacement. Mathematically...

Proteins

PROTEINS Introduction Proteins are the most abundant organic compounds to be found in cells and comprise over  50%  of their total dry weight. They are present in all types of cells and in all parts of the cell. Function Proteins perform many functions. Some of their important functions are; They  build many structures  of the cell. All  enzymes  are proteins and in this way they control the whole metabolism of the cell. Some hormones  are also proteins and regulate metabolic processes. Some proteins (e.g.  haemoglobin )   work as carriers and transport specific substances such as oxygen, lipid, metal ions etc. Some proteins called  antibodies , defend the body against pathogens. Blood clotting  proteins prevent the loss of blood from the body after an injury. Movement  of organs and organisms and movement of chromosomes during anaphase of cell division, are caused by proteins. Amino acids as units of protei...
