| 3 | BIOLOGICAL CLASSIFICATION
🚥2 kingdom classification - Carlous Linnanous
🚥5 kingdom classification - RH whittaker (1969)
🚥 Bacteria are of two types 1)archaebacteria (old) 2) eubacteria (true)
🚥Mycoplasma doesnt posses cell wall smallest living cells can survive without oxygen
🚥Chrysophytes (includes diatoms nd golden algae) walls are made of silica. These are chies producers in ocean
🚥 Dinoflagellates (cell wall has stiff cellulose plates) have two flagella one longituuone transverse.
(Red tides)
🚥Euglenoids (protein rich layer k/as pellicle)
🚥Slime moulds in suitable condition form aggregation k/as plasmodium nd during unfavorable condition it forms fruty bodies
🚥Protozoans (primitive relative of animals)
🚥 Kingdom fungi
Fungi are filamentous contain thread like structure called hyphae mass of hypahe called mycelium
🚥 Meiosis in zygote result in haploid spores
🚥Phycomytes
Mycelium is aseptate nd coenocytic asexual rep takes place by zoospores(motile) nd aplanospores(non motile)
🚥Ascomytes (sac fungi)
Mycelium us branch nd septate asexual spores sre conidia nd sexual spores are ascospores
🚥Basidiomycetes (bracket fungi)
Asexual spores absent nd vegetative rep by fragmentation
🚥Deuteromycetes (imperfect fungi) rep only by asexual spores called conidia
🚥 Kingdom plantae
Life cycle of plants has two phase
1) diploid sporophytic
2)haploid gametophytic
🚥Kingdom animalia
Heterotypic multicellular eukaryotic org that lacks cell wall
🚥 Viruses (non cellular org) these are obligate parasites mostly virus have single strand rna protein coat called capsid protects nucleic acid
🚥 Viroids (rna of Viroid is low molecular weight)
🚥Prions (similar to virus has abnormal protein)
🚥Lichens symbotic ass bw algae nd fungi algal comp called phycobiont nd fungal component called mycobiont
🚥mycorrhiza fungi in association with algae as lichens with roots of higher plants | 37 |

❖ Substances that absorb or emit light discontinuously in the form of small packets or bundles.
❖ The smallest packet of energy is called quantum (plural quanta).
❖ The radiation is propagated in the form of waves.
❖ The energy of a quantum is directly proportional to the frequency of the radiation
E ∝ v
E = hv
E = (hc)/ λ =hc v
Where E = Energy of radiation
h = Planck's constant
= 6.626 * 10^-27 * erg .sec
= 6.626 * 10^-34 Joule.sec
❖ A body that can absorb or emit energy in whole number multiple of quantum.
E = nhv
Where n = 1, 2, 3, 4

1. (α+в)²= α²+2αв+в²
2. (α+в)²= (α-в)²+4αв
3. (α-в)²= α²-2αв+в²
4. (α-в)²= (α+в)²-4αв
5. α² + в²= (α+в)² - 2αв.
6. α² + в²= (α-в)² + 2αв.
7. α²-в² =(α + в)(α - в)
8. 2(α² + в²) = (α+ в)² + (α - в)²
9. 4αв = (α + в)² -(α-в)²
10. αв ={(α+в)/2}²-{(α-в)/2}²
11. (α + в + ¢)² = α² + в² + ¢² + 2(αв + в¢ + ¢α)
12. (α + в)³ = α³ + 3α²в + 3αв² + в³
13. (α + в)³ = α³ + в³ + 3αв(α + в)
14. (α-в)³=α³-3α²в+3αв²-в³
15. α³ + в³ = (α + в) (α² -αв + в²)
16. α³ + в³ = (α+ в)³ -3αв(α+ в)
17. α³ -в³ = (α -в) (α² + αв + в²)
18. α³ -в³ = (α-в)³ + 3αв(α-в)
