Match the following animal groups with their characteristics:
Parazoa (phylum Porifera) = Lack tissues organised into organs and have indeterminate shape Eumetazoa = Have tissues organised into organs and organ systems Grade Radiata = Includes simplest of the Eumetazoa (phylum Cnidaria) Coelomata = Have a true coelom
Match the following subkingdoms/groups with their respective number of phyla:
Parazoa = 1 (phylum Porifera) Eumetazoa = Many (about 29 phyla) Acoelomata = Group without a body cavity Pseudocoelomata = Group with a false coelom (pseudocoel)
Match the following characteristics with their corresponding animal groups:
Animals without a body cavity = Acoelomata Animals with a false coelom = Pseudocoelomata Animals with a true coelom = Coelomata Animals with tissues organised into organs and organ systems = Eumetazoa
Match the following grades with their respective symmetrical characteristics:
Radiata = Radially symmetrical Bilateria = Bilaterally symmetrical Parazoa = Asymmetrical Eumetazoa = Can be radially or bilaterally symmetrical
Name the two subkingdoms of animals mentioned in the text and briefly describe the key differences between them.
The two subkingdoms of animals mentioned are Parazoa and Eumetazoa. Parazoa animals lack tissues organised into organs and have indeterminate shape, and are asymmetrical. Eumetazoa animals have tissues organised into organs and organ systems and can be either radially symmetrical or bilaterally symmetrical.
How many groups have the animals in subkingdom Eumetazoa been divided into based on the presence, absence, or type of body cavity found in them? Name the groups.
The animals in subkingdom Eumetazoa have been divided into three groups based on the presence, absence, or type of body cavity found in them. The groups are Acoelomata, Pseudocoelomata, and Coelomata.
What are the characteristics of animals grouped under Acoelomata, Pseudocoelomata, and Coelomata?
Animals grouped under Acoelomata do not have a body cavity, animals grouped under Pseudocoelomata have a false coelom, the pseudocoele, and animals grouped under Coelomata have a true coelom.
Name the simplest animal included in grade Radiata and its corresponding phylum.
The simplest animal included in grade Radiata is from the phylum Cnidaria.
Which subkingdom includes animals with tissues organised into organs and organ systems?
Eumetazoa
How are animals without a body cavity grouped?
Acoelomata
Which grade includes the simplest animals of the Eumetazoa?
Radiata
How many groups have the animals in subkingdom Eumetazoa been divided into based on the presence, absence, or type of body cavity found in them? Name the groups.
Three groups: Coelomata, Pseudocoelomata, and Acoelomata
Animals in subkingdom Eumetazoa have been divided into four groups based on the presence of body cavity
False
Subkingdom Parazoa includes animals that lack tissues organised into organs and have indeterminate shape
True
The animals in subkingdom Eumetazoa have tissues organised into organs and organ systems
True
Animals in grade Radiata are more complex in organization compared to other Eumetazoa
False
Explain the key differences between subkingdom Parazoa and subkingdom Eumetazoa in terms of their organization and symmetry.
Subkingdom Parazoa (phylum Porifera) includes animals that lack tissues organized into organs, have indeterminate shape, and are asymmetrical. Subkingdom Eumetazoa includes animals of other phyla with tissues organized into organs and organ systems. Eumetazoans can be either radially symmetrical (grade Radiata) or bilaterally symmetrical (grade Bilateria).
Describe the basis for dividing animals in subkingdom Eumetazoa into three groups based on the body cavity found in them.
Animals in subkingdom Eumetazoa are divided into three groups based on the presence, absence, or type of body cavity found in them. The groups are Acoelomata (lack body cavity), Pseudocoelomata (have a false coelom), and Coelomata (have a true coelom).
Explain the characteristics of animals grouped under Acoelomata, Pseudocoelomata, and Coelomata.
Acoelomata includes animals without a body cavity, Pseudocoelomata includes animals with a false coelom, and Coelomata includes animals with a true coelom.
Identify the simplest animal included in grade Radiata and its corresponding phylum.
The simplest animal included in grade Radiata is found in the phylum Cnidaria, which includes animals like jellyfish and sea anemones.
Animals in subkingdom Parazoa belong to phylum ______
Porifera
The sub kingdom Eumetazoa includes animals with tissues organised into ______ and organ systems
organs
The animals without a body cavity have been grouped under ______
Acoelomata
The animals which have a false coelom have been grouped under ______
Pseudocoelomata
Match the following subkingdoms/groups with their respective number of phyla:
Subkingdom Parazoa = 1 Subkingdom Eumetazoa = 29 Acoelomata = 0 Pseudocoelomata = 0
Match the following characteristics with their corresponding animal groups:
Animals in grade Radiata are more complex in organization compared to other Eumetazoa = False Animals belonging to subkingdom Parazoa have tissues organised into organs and organ systems = True The animals which have a false coelom, the pseudocoele, have been grouped under ______ = Pseudocoelomata The animals without a body cavity have been grouped under ______ = Acoelomata
Match the following grades with their respective symmetrical characteristics:
Radially symmetrical animals (grade Radiata) = True Bilaterally symmetrical animals (grade Bilateria) = False Animals in subkingdom Eumetazoa can be either radially symmetrical or bilaterally symmetrical = True Subkingdom Parazoa includes animals that lack tissues organised into organs and have ______ shape = Indeterminate
Match the following animal groups with their characteristics:
