Students of botany class expressed that their class is very boring. Next day Smita madam brought a few botanical samples. She asked the class to group the plants according to some criteria. They classified the plants and tabulated their observations as in the table below. Looking at this information, she asked them to find out the correct set belonging to Pteridophyta & Algae respectively.

• A. II & V
• B. II & I
• C. III & V
• D. II & III

Answer 1

The correct option is A II & V

The pteridophytes are the spore producing plants which do not produce seeds and flowers. These are the vascular plants and cones (Strobilus in Equisetum)which are structures producing spores are present. Tissue differentiation is present as the plant body is differenciated into root ,stem and leaves and habitat is terrestrial.

The algae do not produce seeds and they are nonvascular. They do not have flowers or cones. There is no tissue differentiation and the habitat is aquatic.

Example : Chara, Spirogyra etc

So, the correct answer is 'II & V'
