Diversity of Autotrophs

Study Review

Photosynthetic Pigments

Are chemicals that absorb specific wavelengths of light depending on their chemical structure.

Gametophyte

A haploid (n) phase in the life cycle of Viridiplantae that produces the gametes

Sporophyte

A diploid (2n) phase in the life cycle of Viridiplantae that produces spores.

Thallus

A flattened body form of the gametophyte.

Rhizoids

Are hair-like structures that bind the thallus to the substrate

Xylem

A tissue that primarily carries water from the roots toward the leave via evapotranspiration and is dead at functional maturity

Phloem

A tissue that primarily carries sugar from the leaves to other tissues using hydrostatic pressure and is alive at functional maturity

Pollination

An occurrence when the male and female gametophytes unite
