Today we are going to discuss about cells.
00:03
The cells are the basic unit of life.
00:09
Based on the number of cells, an organism may be classified to be prokaryotic or eukaryotic.
00:21
The prokaryotic organisms are unicellular, whereas eukaryotes are generally multicellular.
00:38
The cell membrane is a structure that surrounds the cell.
00:46
It is responsible to provide support to the cell.
00:54
A cell membrane is also known as plasma membrane and it is composed of two layers composed of phospholipids.
01:10
Thus the cell membrane is known to be phospholipid bilayer.
01:16
The nucleus is the structure that consists of the dna or the genetic material of the organism.
01:26
The dna stands for deoxyribonucyginate acid.
01:32
A collection of dna along with proteins form the structure known as chromatin.
01:46
Chromatin forms the chromosome in a cell.
01:50
The structure of microfilament is rod -like and solid and helps to provide structural support to the cell during the process of division.
02:16
Celia is a structure that provides motility to the cell and it is also used in certain organism as a sensory organ to sense the surroundings of the organism.
02:38
A phospholipid bilayer is formed by lipids attached to a phosphate group making the molecule amphipatic.
03:05
That is, it has both hydrophobic and hydrophilic ends.
03:11
This is present in the plasma membrane or the cell membrane and allow the entry to selective molecules across the membrane.
03:26
The structure of flagella is hair -like and is known to provide motility to the cell, that is assist in the movement of the cell.
03:44
The term phlegelum means whiff, that is, it appears to be whiff light and helps to propel the cell in a medium of fluid.
04:03
Cell organelles are membrane bound structures and found in the eukaryotes.
04:19
During the process of ingestion, the lysosome, which consists of enzymes, take active part and release the enzyme for the breakdown of food.
04:36
During the process of digestion, the plasma membrane plays an important role...
