Today we are going to discuss about cell.
00:04
The cell is the basic unit of life.
00:09
Based on the number of cells, an organism may be classified to be unicellular or multicellular.
00:22
The cellular organics are important structures found within the multicellular organisms like corgi bodies or endoplasmic reticulum that conduct different structures found within the multicellular organisms like corgi bodies or endoplasmic reticulum that conduct different functions in the cell.
00:43
The two types of organisms that is prokaryotic like bacteria or eukaryotic like animals or plants can be classified based on whether the nucleus is present or absent.
01:02
A true nucleus is the nucleus which has a nuclear membrane.
01:12
Eukaryotic organisms have a true nucleus but it is not present in the prokaryotic organetal.
01:20
Within the nucleus, the chromatine is present, which is basically dna along with proteins.
01:32
The gel -like substance within which the chromatine is called nucleoplasin, whereas nucleolus is the condensed region of the chromatine, where the synthesis of ribosome takes place.
02:05
The chromosomes found within the nucleus is the structure that is formed of dna and proteins and therefore carries the genetic information of the organism.
02:24
The nuclear membrane surrounds the nucleus in the cell.
02:32
Pytoplasm is the outer region of the cellular organelles and nucleus where the organelles remain suspended.
02:56
The process of cell division involves the formation of daughter cells from the parent cell.
03:07
In this process the chromosome of the parent cell gets divided and passes on to the daughter cells.
03:26
A structure called spindle - fibers attached to the chromosome or chromatids which are the identical halves of the chromosome and pull the chromatids in opposite direction towards the opposite poles after which the cell divides and the chromatics are passed on to the daughter cells.
03:57
The spittle fibers are a aggregate of microtubules which helps in the passage of chromatids to the individual.
04:07
Individual tortoises.
04:09
The structure of a cell was identified by robert hoek when he observed a piece of cork under microscope.
04:28
It was seen that cork had honeycomb -like structure, which he referred to as cells.
04:43
Anton van leeuwenhoek was the first scientist to study microorganism under a microscope.
04:56
He studied protozoa under the microscope.
05:03
The endoplasmic critulum has an important function of the cell in protein synthesis and dipid synthesis.
05:20
There are two types of endoplasmic reticulum, rough and smooth.
05:24
The rough endoplasmic reticulum consists of ribosomes attached to it which gives it the name.
05:35
The structure called vacuoles are intermembrane bound organelles that are found in both procarriots and eukaryotes.
05:56
This function of the vacuoles may be storage or elimination of substances from the cells.
06:09
The cells are the basic unit of life.
06:13
Cells form tissues that are known to form the organs.
06:19
The organs that have simpler functions form an organ system...
