Explanation

Chlorophyll, the pigment responsible for photosynthesis in plants, features a porphyrin ring structure at its core.

A magnesium ion is centrally located within this porphyrin ring, held in place by bonds with nitrogen atoms from the pyrrole rings.

Explanation

In bryophytes, the gametophyte generation is dominant.

This means the leafy, green, haploid structure that is typically seen is the gametophyte, which is the most visible and longest-lived part of the bryophyte life cycle.

The diploid sporophyte is generally smaller and dependent on the gametophyte for survival.
