They probably arose from the algal division Chlorophyta. Opportunities for active photosynthesis were considerably enhanced when plants established themselves on land.
EXAMPLE 1 Light is more available on land, where it is filtered only through the atmosphere, than it is in the often churning and murky waters of lakes and seas. Another vital ingredient for photosynthesis, CO2, is also much more abundant and readily absorbable on land than in the water. Virgin invasions of land were probably highly successful for these reasons, especially at a time…
