The advanced characteristics of the sporophyte of hornworts (anthocerotae) that enable them tothrive better on land are the presence of:
Correct answer: B. Stomata and chloroplasts in the epidermis
- A. Rhizoids, which help to anchor the plant
- B. Stomata and chloroplasts in the epidermis
- C. Horn-like projections out of the gametophyte
- D. Mature sporangium that splits open at the ends
Explanation
The correct answer is Option B: stomata and chloroplasts in the epidermis.These features are essential for the sporophyte's adaptation to land because they facilitate photosynthesis and gas exchange. Stomata allow for the regulation of gas exchange and water loss, while chloroplasts enable the sporophyte to perform photosynthesis, making it less dependent on the gametophyte for nutrients.
