Are unicellular organisms primitive?
Yew , unicellular organisms are more primitive as compared to multicellular organisms .
Why are blue green algae called primitive 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.
What is a primary heterotroph?
A primary heterotroph is an organism that cannot produce its own food through photosynthesis or chemosynthesis and must consume other organisms or organic matter to obtain energy. This includes animals, fungi, and certain types of bacteria that rely on external sources of organic nutrients for survival.
What are the most primitive organisms today are thought to have a structure that is too simple to be considered cells.?
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.
How does a Flatworms anterior-posterior orientation affect their movement compared to the movement of more primitive organisms?
Flatworms 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.
Are unicellular organisms primitive?

Does homeostasis apply only to multicellular organisms?
no very cell need nutrients and expells but homeostasis is primitive in case of unicelluar organism

Are protozoas single celled organisms?
Yes, they are very primitive forms of life.
Can the box jellyfish see?
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.
What is the most primitive kingdom?
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.
What are lower animals?
lower animals are primitive organisms and aren't as smart as humans, mammals etc.
Why is melanin important to the skin?
Because it's the most primitive and universal pigment in living organisms.
What is a primitive animal?
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.
What is a primitive cell?
when constituent particles are present only on the corner positions of a unit cell , it is called as Primitive unit cell .
Flatworms are the first organisms you have discussed with an anterior-posterior orientation How does this affect their movement compared to the movement to of more primitive organisms?
Flatworms are themselves a rather primitive organism. However, having the orientation of anterior-posterior allows them to move their anterior towards food and their posterior away from irritants, which are movements that organisms without this orientation can't do.-Hilary Kinyua
