Euglenoids have two flagella, one lies longitudinally and the other transversely

Slime mould spores are dispersed by air currents

In diatoms, the cell walls form two thin overlapping shells, which fit together as in a soap box.

Text Solution

Verified by Experts

The correct answer is:

This statement is incorrect because:

• The feature of having two flagella (one transverse and one longitudinal) belongs to dinoflagellates, not euglenoids.

• Euglenoids (e.g., Euglena) typically have one or two flagella arising from the anterior end, not arranged in transverse and longitudinal positions.
