CBSE (Central Board of Secondary Education)

Cell is unit of living organisms discover by Robert hook in dead cell and live cell is by Anton von nucleus is proposed by Robert Brown and cell theory is given by Schwan and scheldin. Cell has smallest is McCool and largest is ostrich egg.two types of cell is prokaryotic and eukaryotic cell

Introduction of Cell (in Hindi)

Prokaryotic cell has primitive type of nucleus in which cell envelop has plasma membrane, cellular wall and glycocalyx and cytoplasm has enzymes and mesosomes.dna is double stranded and inside the cytoplasm plasmid is present.

Prokaryotic Cell(in Hindi)

Animal cell contain central nucleus which has nucleolus, chromatin, nucleoplasm,  nuclear membrane and nuclear pores. Nuclear membrane has a structure in which surface of other ribosomes are arranged this is called rough endoplasmic retouch when absent called smooth ER.and mitochondria, lysosomes, golgibodies are also presents.in plant cell cell wall larger central vacuole and chloroplast presents and other organelles are same to animal cell.

Animal Cell and Plant Cell(in Hindi)

Sandwich model is discovered in 1939.it has outer proteins globular and inner bilayer phospolipids.head of phospho lipids are hydrophilic and tail is hydrophobic.

Plasma Membrane(in Hindi)

Unite Membrane Model of Plasma Membrane(in Hindi)

Fluid mosaic model is acceptable because it gives two types of proteins extrinsic and intrinsic proteins.and also shows movements of phospholipids.transitional and flip flop movement.

Fluid Mosaic Model of Plasma Membrane(in Hindi)

Transport across the plasma membrane has two types active and passive transport.

Transport across the plasma membrane.

Osmosis meaning movement of solvent from higher concentration to lower concentration.in animal and plant cell exosmosis and endosamosis is takes place.

Passive transport osmosis PM 5

Diffusion is movement of solute from higher concentration to lowerconcentration till equilibrium.temprature distance and density of medium is factor for diffusion.facilitated diffusion has facility of carrier proteins.

Plasma membrane 7 (Diffusion)

Active transport is done by embedded protein in which sodium potassium pump is takes place as the result of dissociation of TAP.

Active transport of plasma membrane 8

In plasma membrane has two types of process endocytosis and exocytosis.endocytosis meaning taken in exocytosis.exocytosis meaning thron out.

Endocytosis and exocytosis

Cell wall made by cellulose pectin and outer layer is tertiary cell wall then secondary and primary cell wall it has cellulose pectin.

Cell wall introduction and composition

Cell wall is originated from cytokinesis and function is protective also provides shapes.enzymatic nature....

Cell wall structure and functions

Cytoplasm is semi fluid which is responsible for containin cytoplasmic structure and in cytoplasm glycolysis is takes place. Various metabolic activity is takes place in cytoplasm.

Cytoplasm:(in Hindi)

Endoplasmic reticulum has two types smooth and rough endoplasmic reticulum.on SER  ribosomes are absent and on RER ribosomes is presents.

Endoplasmic reticulum

RER has ribosomes and form proteins tubular part form lipids they form Golgi body.compartment also form from this.it has 30 enzymes etc..

Functions of endoplasmic reticulum

Ultra structure is given by Dalton and shape is variable so called as pleomorphic.size is also variable and it shows clear cytoplasmic area called zone of exclusions.

Golgi body introduction

Golgi body discovered by Dalton has vessical cisternae and vacuole.vessical is small vacuole is large in size.

Structure of golgi body

Lysosome is discovered by Duve 1955.it is spherical in shape and has 4 types So called polymorphic organell.pri lysosome,sec lysosome, ter lysosome and auto lysosome.

Lysosomes introduction and types

In enzymes of lysosome proteases, dnase rnase etc enzymes are present it has function like autophagy.autolysis, and defence.

Lysosomes enzymes and functions

GERL system shows connection of ER golgibodies and lysosome with endocytosis and exocytosis..to increase the  surface area.

GERL system

Ribosomes is discovered by palad and it has two types 70s and 80s.70s is presents in prokaryotic cell and organelles like mitochondria and chloroplasts.8os is presents in eukaryotic cell.

Ribosomes introduction

Ribosomes has 70s and 80s types in which larger sub unit is binds to ER by a proteins called ribophorin.

70s and 8os type of ribosomes

Fir assembly of ribosomes mg kon concentration is 0.001M is required and function of ribosome is protein synthesis.

Functions of ribosomes

Microbodeis are arise from ER it has three types spherosome,glyoxysome, and peroxysomes.

Microbodies

Mitochondria is discovered by banda and one in algae 5 lk in flight muscles cell..structure is described in vedio lecture

Mitochondria introduction

Mitochondria has F1 practical which form ATP and present on inner membrane.

Mitochondria F1 practical

Plastids is presents in only plant cell also in some protists.it divided into two types leukoplast and chromoplast.

Plastids

Leukoplast and chromoplast is divided into 3 types.lekoplast has amyloplas, aleuronplast and feoplast

Types of leukoplast and chromoplast.

Chloroplasts is discovered by Anton von and has outer and inner membrane in inner membrane matrix has stroma in stroma dark reaction is formed in grana light reaction is formed.

Chloroplast

Cilia and flagela is locomotory organs present out side the cell

Cilia and flagela

Internally cilia and flagela is same and has 9+2 microtubules.9 are peripheral and 2 are central.9 peril made by protofilament.and has tubuline protein which is alpha and beta protein.and in doublet form.

Internal structure of cila and flagela

Internal structure of cilia and flagela shows central 2 microtubules and has dynien protein central 2 are called C1 and C2 which is connected by cross bridge.

Structure of cilia and flagela

Internal structure of centriol and basal granules are common external is differently.and has triplet microtubules made by tubulin proteins.

Centriol and basal granules

Microtubules and microfilament has differ.microtubules has tubulin proteins, microfilament has actin protein.

Microtubules and microfilament

Vacuole is large in plant cell and small in animal cell it has sap in plant cell which has water AA.nutrient etc.

Vacuoles

Function of golgibodies has glycosilation with lipid and proteins. With carbohydrates

Functions of Golgi body

Nucleus is discovered by Robert Brown.in orchids.nucleus has fluid called nucleoplasm.which has chromatin fiber and nucleolus etc.

Nucleus

Nucleus has inner and outer membrane and inside this nucleoplasm,nuclear power, chromatin fiber is presents.

Nucleus structure
