Question

Algae having apical cap and cap cell


​

Answer 1

Explanation:

Oedogonium is an unbranched, filamentous green alga that is easily identified by the distinctive rings at the apical ends of certain cells. Each cellular division creates a new ring on the cap cell.

Answer 2

Oedogonium is an example of algae having apical cell and cap cell

• Oedogonium is a member of Chlorophyceae(green algae) under kingdom Plantae.
• The body is thalloid i.e the plant is undifferentiated into the stem, leaves and roots.
• They are multicellular and made up of unbranched filaments. The cells are elongated and cylindrical.
• Apical cells and cap cells are the characteristic features of this algae.
• The terminal cell of the filament is called the apical cell and the lowermost cell is called the basal cell which is a multilobed and finger-shaped structure that attaches the filament to the substratum.
• The apical cell is rich in chloroplasts and green in colour and performs the photosythesis.
• The cells between apical cells and the basal cells are called intercalary cells. After the division, some intercalary cells develop a cap-like structure in their upper part called cap cells.
• Each cellular division creates a new ring on the cap cells.
