Competitive Exams: Revision Terminology Part 15

Biocoenosis – karl Mobius.

Microcosm – SA Forbes.

Geobiocoenosis - Sumaches.

Holocoen – friederichs.

Plant depend completely on ground water = phreatophytes intertidal zone – between high & low tides.

BOD amount of organic waste present in water

Addition of plant nutrients (excess) intensifies eutrophication

Oysters – Zn

Fisher – Fe

Marine animal – Sr

Number of mitochondria increment in germinating seeds.

No cell can live without protein (enzyme)

Neoplasm – autonomous new growth of cells (tumors)

Green plant cell nuclear, mitochondrial & Chloroplast genome present

Mesokaryotes – genetic material is surrounded by nuclear member but histones is not associated with DNA e.g. Dinoflagellates.

as cell in size, metabolic activities increment, but surface: volume ratio decrement

protoplasm – polyphasic, Colloidal, Coagulate above 60 degree Celsius, alkaline, Sp. Gravity > 1, irritability, show Brownian & Tyndall effect.

Danilli & Davison model – PLP Membrane

Singer son & Nichol son model = Fluid mosaic model - protein icebergs in sea of lipids

Singer son Carbohydrate bond to membrane = glycocalyx (most complex of glycolipids are gangliosides – one or more Salic acid residue = n – acetyl neuramiric acid NANA & has a negative charge)

Glycophorin in member of RBC.

Glycoproteins act as antigens.

Fluidity increment with decrement length of fatty acid tail.

Beetroot do not loose color, as Plasma Membrane is impermeable to movement of molecules.

Permease are not engineering as they do not alter chemical nature but move substrate from one Comportment to the another

Proteins transport ions.

Protein free lipid member is impermeable to icons but freely permeable to water

Large molecule like cholesterol – ingested by endocytosis & removed by exocytosis

Plant, Bacteria & fungi proton pump creates a negative member potential by transporting H⁺ from cytoplasm to fluid (interior is negative charged relative to exterior)

Microfilament – actin – movement of plasma member, microvilli, contraction of muscle fibre

Microtubules – tubulin – cilia, flagella, spindle formation

Repeated nuclear division (without cytoplasmic division (i) Walled- Coenocyte – Rhizopus, vaucheria.

(ii)Non walled – plasmodium- Slime molds

Both nuclear membrane pinched to form vesicles.

Histone
