Scientists believe that plants evolved directly from a freshwater green algae called charophyte. There are two different types of charophytes, coleochaetales and charales, which strongly resemble earliest land plants.
green algea
from green algea that went into land plants which now represents present day chloroplast
Angiosperms They produced seeds that are protected they are the most diverse and abundant land plants today. Present day angiosperms that evolved during the mesozic era include magnolia and oak trees.
Land plants first appeared in the Silurian period. This period took place during the Paleozoic Era. This was 438 million years ago.
Land plants evolved from Charophyceans. Charophyceans lived in the water and land plants dont.
Land plants are believed to have evolved from algae that came from oceans, to freshwater, to wet-dry coatlines, and developed into ferns/shrubs.

They evolved to fill the niches found on land.
Many scientists believe that ancient green algae evolved into land plants. The chloroplasts present in green algae are the same as those of land plants. In addition, green algae have cell walls of similar composition to land plants; both store food, such as starch, in the same manner. Most green algae live in freshwater habitats with highly variable conditions. The ongoing changes in their environment have made them highly adaptable.what-evidence-has-led-scientists-to-believe-land-plants-evolved-from-green-algae

Nonvascular plants and seedless vascular plants are both land plants that evolved from green algae. Both types also rely on water to be able to reproduce.

Plants in the sea evolved about 3,600 million years ago. The first algal scum on land about 1,200 million years ago, The first first land plants appeared around 450 million years ago in the Ordovician period.
