Natural system of classification was introduced by
George Bentham and Joseph Dalton Hooker
Phylogenetic system of classification was introduced by
Engler and Prantl,Hutchinson, takhtajan
What is the basis of cytotaxonomy/karyotaxonomy
Chromosome number,
Structure,
Behaviour etc.
What is the basis of chemotaxonomy
Chemical constituents of the plant
Colonial form of algae
Volvox
Filamentous algae
Ulothrix
Vegetative propagation of algae
Fragmentation
Why are algae called thalloid
As the plant body is not differentiated into root ,stem and leaf.
The most common spore produced in an algae is
Zoospores
Sex organs of Algae are
Non jacketed and unicellular
Isogamous type of sexual reproduction in algae is seen in
Chlamydomonas, Spirograph
Which all are the classes of division algae
Chlorophyceae
Phaeophyceae
And rodophyceae.
The pigments of chlorophyceae
Chlorophyll a, chlorophyll b, carotene and xanthophyll.
Shapes of chloroplast in algae
Discoid Plate like, Reticulate Cup shaped, Spiral or ribbon shaped
The storage bodies in green algae are called
Pyrenoids
Pyrenoids are made up of
Protein and starch
In some green algae food is stored as
oil droplets
The cel wall of green algae is made of
Inner layer of cellulose and outer layer of pentode
Some commonly found green algae are
Chlamydomonas, volvox, ulothrix, Spirogyra and chara .
Pigments present in phaeophyceae
Chlorophyll a and c , carotenoids and xanthophylls.
The brown algae with simple branched and filamentous
Ectocarpus
The brown algae whose body is profusely branched
Kelps, which can reach a hieght of 100m.
In brown algae food is stored as complex carbohydrates which may be of the form
Laminating or manitol( alcoholic sugar).
