Bryophytes can be separated from algae because they

Bryophytes can be separated from algae because they possess archegonia with outer layer of sterile jacket cells.

Bryophytes (like mosses and liverworts) are a group of non-vascular plants that differ from algae in several ways. One key difference is the presence of archegonia in bryophytes. Archegonia are specialized structures where the female reproductive cells (eggs) are produced. In bryophytes, these archegonia are surrounded by a layer of sterile cells called the jacket cells. This outer layer helps protect the reproductive cells and supports the plant's reproductive process.

Here's why the other options are not correct for distinguishing bryophytes from algae:

• A. Are thalloid forms: While some bryophytes are thalloid (like liverworts), others are leafy (like mosses). Algae can also be thalloid, so this isn't a unique feature of bryophytes.
• B. Have no conducting tissue: Both bryophytes and algae lack vascular tissue (like xylem and phloem), so this characteristic doesn't help separate them.
• D. Contain chloroplasts in their cells: Both bryophytes and algae have chloroplasts, as they both perform photosynthesis, so this feature is common to both.

Thus, the presence of archegonia with jacket cells is a distinctive feature that sets bryophytes apart from algae.
