Microbicides cilia and flagella centriole and basal bodies

12TH PHYSICS

The microbodies t i n y but important
These are small sac like structures bounded by the single membranes these are of different kind of which we will take up 3 peroxisomes and Kalai oxisomes
Lysosomes
L y s i s background soma body
Lysosomes are present in almost all animal cells and some non green plants as they perform intracellular digestion
Features of lysosomes are as follows
Membranous sacs budded off for LG body
Maybe dates in a single cell contains several enzymes about 14 number girls to be acted upon by enzymes enter the lysosomes lysosomes are called suicidal bags as enzymes content in them can digest the cells on material when damaged or dead
Importance of intracellular digestion by the lysosomes
Help in nutrition of the cell by digesting food as they are rich in Warriors hydrolyzing enzymes which enables them to digest almost all major chemical constituents of the living cell
Help in difference by distinctions as in white blood cells help in cleaning of the cell by digesting damaged material of the cell provide energy during cell starvation by digestion of the on parts of the cells autophagic auto self
Help param sales entering the egg by breaking through digesting the egg membrane in plant cells mature balam cells loss all cellular contents by lysosome activity when cells are old diseased or injured lysosomes attack their cell organelles and digest them and other words lysosomes are autophagic self devouring
Peroxisomes
Found both in plant and animal cells found in the Green Leaves of higher plants they participate in oxidation of substrates resulting in the formation of hydrogen peroxide they often contain a central core of crystalline material called nucleoid composed of urate oxidase crystals these bodies are most historical or avoid and about the size of Mitochondria and lysosomes they are usually closely associated with endoplasmic reticulum they are involved in photo respiration in plant cells they bring about fat metabolism in the cells
Glyoxysomes
Microbodies present in plant cells and morphological is similar to peroxisomes found in the cell of yeast and certain fungi and oil-rich seeds in plants functionally they contain enzymes of fatty acid metabolism involved in the conversion of lipids to carbohydrates during germination
Saliya and flagella the organelles motility
Some unicellular organisms like Paramecium and euglena swim in water with the help of cilia and flagella respectively and multicellular organisms some living tissues epithelial tissues have cilia debit and create a in the fluid in order to move in a given direction example in the wind pipe trachea to push out mucus and dust particles beat like any course for girls age in a Boat and flagella bring about a place like moment both are made up of contractile protein to bolen in the form of microtubules the arrangement of the microtubules is termed as 9 + 2 that is to Central microtubules and 988 sets surrounding them
Celia
Salter 5 to 10 micrometre several hundred percent structure protoplasmic projection and membrane-bound consists of 9 sets of peripheral duplet microtubules and one set of two similar to balls in the centre
Play Jila longer 15 micrometre usually 1 or 2 and most sales CM age in cilia
Centriole
It is a present in all the animal cells but not in Amoeba located just outside the nucleus it is cylindrical 0.5 micro metre in length and without a membrane it has 9 sets of peripheral tubules but known in the centre + 0 each set has 32 balls arranged at define night angles it has its own DNA and RNA and therefore it is self replicating
Function
Centrioles are involved in cell division they give orientation to the mitotic spindle which forms during the cell division
Basal bodies
30,000 structures similar to centrioles they have the same 9 sets of triplet organisation 9 + 0 8 in the centrioles the cilia and flagella appear to rise from the basal bodies
