∙ 9y agoFlatworms have a defined anterior (head) and posterior (tail) orientation, which allows for more coordinated movement compared to primitive organisms like sponges or jellyfish. This orientation enables flatworms to exhibit bilateral symmetry, where movements are more directional and purposeful since they have distinct front and rear ends. Primitive organisms lack this level of organization and may exhibit more random or undirected movements.
No, flatworms are multicellular organisms with a simple body plan, but they do not have many cells compared to more complex organisms. They typically have around a few thousand to a few million cells.
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
Blue green algae are considered primitive organisms because they are among the earliest organisms to have evolved on Earth. They are simple, single-celled organisms that lack a true nucleus and other complex cell structures found in more advanced organisms. Their evolutionary history dates back billions of years, making them one of the oldest known groups of organisms.
Viruses are considered the most primitive organisms that lack the complexity to be considered cells. They consist of genetic material (DNA or RNA) enclosed in a protein coat and are unable to carry out metabolic processes on their own.
a. Archaea. Archaea are known to inhabit extreme environments similar to those of primitive Earth, such as hot springs, deep-sea vents, and acidic environments. Their ability to thrive in these conditions has led scientists to believe they may resemble the early life forms on Earth.

Yes, they are very primitive forms of life.
No, jellyfish do not see. They have no eyes, and no brains either. They are extremely primitive organisms, the most primitive of all existing multicellular life.
The most primitive kingdom is often considered to be the Kingdom Monera, which includes bacteria and archaea. These organisms lack a true nucleus and other membrane-bound organelles found in more complex organisms.
The most primitive life on Earth are single-celled organisms such as bacteria and archaea. These organisms have simple cell structures and are thought to have been some of the first life forms to appear on Earth billions of years ago.
lower animals are primitive organisms and aren't as smart as humans, mammals etc.
Because it's the most primitive and universal pigment in living organisms.
A primitive animal is a type of organism that is considered to be simple in structure and function compared to more complex organisms. These animals often exhibit features that are similar to ancestral forms, reflecting an earlier stage of evolution. Examples of primitive animals include sponges and jellyfish.
Viruses are considered the most primitive organisms that lack the complexity to be considered cells. They consist of genetic material (DNA or RNA) enclosed in a protein coat and are unable to carry out metabolic processes on their own.
