Read the following statements and choose the correct option: 1. Cytotaxonomy is based on cytological information like chromosome number, structure, behaviour. 2. Chemotaxonomy uses the chemical constituents of the plant to resolve confusions 3. Algae do not contain chlorophyll 4. The form and size of algae is highly variable, ranging from colonial forms like Volvox and the filamentous forms like Ulothrix and Spirogyr

Step-by-step solution

Cytotaxonomy is based on cytological information like chromosome number, structure, behaviour and Chemotaxonomy uses the chemical constituents of the plant to resolve confusions, are also used by taxonomists these days. Algae are chlorophyll-bearing, simple, thalloid, autotrophic and largely aquatic organisms. The form and size of algae is highly variable, ranging from colonial forms like Volvox and the filamentous forms like Ulothrix and Spirogyra
