- Bryophyte β highest evolved sporophyte β Anthrecos.
- Simplest sporophyte β Riccia.
- Celyptra derived kim venter of archegonium hence is haplsid.
- Sterile elongated cells with spiral thickenings in capsule of bryophyte = elaters.
- Oblique septa in rhizoids of moss faciliate faster conduction between adjacent cells.
- Lathyrism β is caused due to consumption of kerasi dal β gross skeletal deformations & thinking of collagen fibres & fibrils, cause pomalysis of lower limbs.
- Algae Chlorella algae β rich in proteins anteromorpha algae β both flesh + marine water.
- Study of algae = phycology.
- Fresh water alges β zygnema, cladophora, spirogyra, ulothrix, Oedogonim.
- Algae attached to submereged vegetation β periphyton
- A Terrestrial alga is edaphophytes.
- Characium algae on antennae of mosquito larvae.
- Os cillosporia algae on guinea pig, deer, tadpole.
- Simonsiella algae on man, horse, cow, pig.
- Algae are auxotrophic β need org camp but not as source of energy.
- Ouadriciliate zoospore β Ulothrix & Cladophore.
- Isogamy β Positive & negative Strains, Chlamydomonas, Ulothrix.
- Anisogamy β male is smaller & active, Spirogyra & zygnema, Pandoria, Aphonochaete.
- Chora β highly evolved sex organs.
- Green algae β glycoproteins rich in hydroxyproline constitute cell wall, uninucleate, 2 contractile vacel (chlamydomonaas) β cup shaped chloroplast with pyrenoid it is a protein body & has CO2 fixing engineering β Ribulose Bifhosphate carborxylase β Store carbohydrate.
- Apirogyra
- Scalciform conjngation β bet cells of different filaments
- Lateral conjugation β bet cells of same filaments.
- Green algae as ancestors of land plants because β contain che a & b in cell & store stomach.
- Carpogonium is a flask shaped female cell with long neck like trickogyne in red algae.
- Not true Mosses:
- Rcinder moss (Cladonia) + Iceland moss = lichen
- Irish moss/Sea moss/Caregeheen moss = Chondrus (red algae)
- Club moss (Lycopodium) = Pteridophytes.
- Bird nest moss (Selgeinella) = Pteridophytes.
- Spanich moss (Tillandsia) = Epiphytic angiospltion.
- Red snow β Chlamydomonas nivalis, Ulothrix, Flaccid a, Smithsoniomonas abbotti, Scoteela nivalis.
- Back snow β Raphidonema.
- Purple snow β Ancylonema nordenskiodoii, merotaenium berggreni.
- Blue snow β Dactyloccocopsis caucasica.
- Yellow snow β Chlamydomonas flavovirens, cystococcus nivicola.
- Brown algae entangled in bottom of ship β cause menace to shipping.
- Alginic acid has haemostatic prop.
- Sod. Alginate β Stabiliser in food.
- Cal. Alginate β Plasties.
- Brown Algae contain small colousless vasciles = fucosan vesicles (to check growth of unicellular organisms)
- Cyanbacteria cyanophycin gramale β aspartic acid: arginine
- Cyanlbacteria polyhedral bodies (RNA associated with DNA)
- Nature heterocyst have nirmal content of chl a but phycobiloproteins are absent. Althoush they retain PS I; PS II and RUBP carbarcylase is absent so they do not fix CO2 & nor produce O2 in light. They provide a protective mech. Against oxygen inhibition of Engineering mitrogenase & provide a good site for M2 fixation.
- Porphyra protein has high protein content used to prepare Laver
- Spiruline β rich in vitamin B complex & Minerab.
- Mostoc β food in china β βyayuchoβ .
