Red Plants Alongside the Green

What many people mayn't know is that there actually three basic types of algae:

Green algae, the origin of the kingdom Plantae

Brown algae, found primarily in kelp forests

And red algae

For this question, let's disregard brown algae because brown algae is a geologic newcomer--no older than 150 million years.

In this alternate scenario, plants evolved from both green AND red algae. Plants descended from green algae are photosynthetic and can be found in every single terrestrial habitat, even deserts. They come in the form of ferns, mosses, grasses, flowers and trees. Would plants descended from red algae behave in the same way, or would they have different environmental requirements from plants descended from green algae?
