Question Detail
Question
What is an unusual feature distinguishing Hornworts from other land plants, as mentioned in the notes?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Section 3.2.4 Morphology of Hornworts (e.g., Anthoceros) highlights: "Hornworts... are distinguished by a long, horn-shaped... sporophyte that grows continuously from a basal meristem and typically contains a single large chloroplast per cell — an unusual feature among land plants (most plant cells have many small chloroplasts)." Both continuous growth from a basal meristem and the single large chloroplast are unusual, but continuous growth of the sporophyte is a key morphological distinction.
Hint
Look for characteristics described as 'distinguishing' or 'unusual' for Hornworts.
