What else can I help you with?
What is the oldest and simplest organism?
Algae or blue green algae
Is green algae a multicellular or unicellular organism?
Green algae can be both multicellular and unicellular organisms.
What are green algae members of and are thought to be the direct ancestor of what?
Green algae are members of the Kingdom Plantae and are thought to be the direct ancestor of land plants. This evolutionary relationship is supported by similarities in cell structure and photosynthetic pigments between green algae and land plants.
Why do scientist think green algae and plants have a common ancestor?
They share chlorophyll.
What group of protists did the first plants evolve from?
The first plants evolved from a group of protists known as green algae. Green algae share many characteristics with plants, such as photosynthetic pigments and cell walls made of cellulose. This evolutionary relationship suggests that plants and green algae share a common ancestor.
What is an example of colonial organism?
example of colonial organisms red algae blue algae green algae volvox
Organism made of a fungus and green algae or a cyanobacteria?
lichen
Which organism have cellulose in their cell walls?
Plants and Green algae
What are the oldest ancestors of plants?
Probably the green algae, which descended from cyanobacteria. Seaweeds come in three colours, green, brown and red, and each has different photosynthetic mechanisms - not only chlorophyll. The intertidal zone may have played an important part in the colonization of the land from aquatic plants.
What organism do scientists believe are plants' ancestors?
The dinosaur is thought to be the ancestor of all things today.
From what did the first plant evolve?
The First Plants evolved From Blue-Green Algae
Is thought to be the ancestor of land plants A. bacteria B.green algae C.ferns or D.red algae?
B. green algae is thought to be the ancestor of land plants. Molecular and fossil evidence suggests that land plants evolved from green algae approximately 500 million years ago. Both share similar traits, such as chlorophyll and cell wall composition, indicating a close evolutionary relationship.
