1.Which plants contain lignified vascular tissue? (Select all that apply.)

Gametophytes of bryophytes

Gametophytes of seedless vascular plants

Sporophytes of bryophytes

Sporophytes of seedless vascular plants

2. Which plants produce multiple sporangia? (Select all that apply.)

Gametophytes of bryophytes

Gametophytes of seedless vascular plants

Sporophytes of bryophytes

Sporophytes of seedless vascular plants

3. Which of the following groups produce sporangia on leaves? (Mark all that apply.)

Hepatophyta

Lycophyta

Bryophyta

Anthocerophyta

Monilophyta

Solution

1. Sporophytes of seedless vascular plants

Explanation- The xylem of seedless vascular plants is partially lignified which makes the wall more rigid.

2. Sporophytes of seedless vascular plants

Explanation- The sporangia are present in clusters, the sori in ferns

3. Lycophyta, Monilophyta

Explanation- Sporangia is borne on the adaxial surface of the leaves in Lycophytes. Sporania in monilophyta are present on leaves.
