The phylum of protozoa characterized by a lack of motility is called Apicomplexa. Members of this group, such as Plasmodium and Toxoplasma, are primarily parasitic and do not have structures for movement. They typically rely on hosts for transport and reproduction. Apicomplexans are known for their complex life cycles and specialized organelles that aid in invading host cells.

What is the family of amoeba?
Amoebas belong to the family Amoebidae within the phylum Amoebozoa. This family includes various species of amoebas that are characterized by their shape-shifting abilities and lack of a fixed form.
Why are Echinoderms classified into phylum Chordata?
Echinoderms are not classified in phylum Chordata. They belong to their own phylum called Echinodermata. Chordates, on the other hand, are characterized by the presence of a notochord, which echinoderms lack.
Almost all animals except what have either radial or bilateral symmetry?
Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.
Are protozoa vertebrates or invertebrate?
Protozoa are classified as invertebrates. They are single-celled organisms that belong to the kingdom Protista and do not have a backbone or spinal column, which distinguishes them from vertebrates. Protozoa can be found in various environments and exhibit diverse forms and functions, but they lack the complex structures associated with vertebrate animals.
Does sporozoa have motility?
Sporozoa typically lack motility in their mature stages. They rely on host cells for movement and reproduction, often using a complex life cycle involving both sexual and asexual stages to complete their life cycle.
What is the family of amoeba?
Amoebas belong to the family Amoebidae within the phylum Amoebozoa. This family includes various species of amoebas that are characterized by their shape-shifting abilities and lack of a fixed form.
Which phylum contains the simplest animals?
The phylum Porifera contains the simplest animals, known as sponges. Sponges lack tissues and organs, and their body structure is very basic compared to other animal phyla.
Why are Echinoderms classified into phylum Chordata?
Echinoderms are not classified in phylum Chordata. They belong to their own phylum called Echinodermata. Chordates, on the other hand, are characterized by the presence of a notochord, which echinoderms lack.
What organism lack colemn and have an unsegmented body belong to the phylum?
Organisms that lack a coelom and have an unsegmented body belong to the phylum Platyhelminthes, commonly known as flatworms. This phylum includes various species such as planarians, flukes, and tapeworms. These organisms are characterized by their flat bodies, bilateral symmetry, and a lack of specialized respiratory and circulatory systems. They typically have a simple body structure and are often found in aquatic or moist environments.
Do protozoas have backbones?
No , Protozoa lack back bone .
What is the phylum traits for a leech?
Leeches belong to the phylum Annelida, which is characterized by segmented bodies, a lack of internal or external skeleton, and bilateral symmetry. Leeches also have a closed circulatory system, a well-developed nervous system, and a body covered in a layer of cuticle.
Almost all animals except what have either radial or bilateral symmetry?
Almost all animals except sponges have either radial or bilateral symmetry. Sponges belong to the phylum Porifera, characterized by their lack of symmetry.
Is an earwig an invertibrate?
Yes, an earwig is an invertebrate. Invertebrates are animals that lack a backbone, and earwigs belong to the class Insecta within the phylum Arthropoda. They are characterized by their elongated bodies and pincers on their rear ends, which are used for defense and mating.
What phylum do sponges blong to?
Sponges belong to the phylum Porifera. They are multicellular aquatic animals that lack tissues and organs.
Lack of peristalsis?
A lack of peristalsis is sometimes called a motility disorder. This means that there is no movement in the bowels which is sometimes caused by an obstruction in the intestine.
What is acraniata?
Acraniata refers to a subphylum of chordates that includes animals without a distinct skull or cranium, such as hagfish and lampreys. They are characterized by a lack of a bony skeleton surrounding their brain.
Does sporozoa have motility?
Sporozoa typically lack motility in their mature stages. They rely on host cells for movement and reproduction, often using a complex life cycle involving both sexual and asexual stages to complete their life cycle.
