A plant cell has chloroplasts while an animal cell doesn't. A plant cell also has a cell wall and a cell membrane, while an animal cell just has a cell membrane.
The more classification levels two organisms share, the more closely related they are in terms of evolutionary history. Organisms that share many classification levels are likely to be more similar in terms of genetics, anatomy, and behavior.
fungi and protists
One characteristic used to place organisms into kingdoms is their ability to make organic molecules through photosynthesis.
Unicellular organisms are organisms that have one cell. They are divided into two quite different types, from different classification kingdoms
The most commonly used classification system today separates organisms into the following kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. This is known as the six-kingdom classification system.
there are five criteria for classification of organisms into kingdoms. they are, 1.cell type (Prokaryote/eukaryote) 2.cell wall (cellulosic/noncellulosic/present/notpresent) 3.nuclear membrane(present/absent) 4.body organisation(cellular/multicellular/tissue/organ/organ system) 5.mode of nutrition(autotrophic/heterotrophic)
absence of a cellular nucleus
They have no nucleus or organelles. They do not move. They obtain their nutrients by absorbing organisms through their cell wall. They are also single celled and microscopic
Fungi and Protista.
absence of a cellular nucleus
Not all kingdoms include unicellular organisms. The kingdoms that do not have unicellular organisms include the plantae and animalia kingdom.
They are all eukaryotic. By this characteristic, they all have true nucleus and membrane bound organelles in their cells.
