Attributes of Animalia Kingdom Classification. The animalia kingdom consists of various multicellular eukaryotic animals. It is one of the kingdoms among the five kingdom scheme of classification (by Whittaker). What is the Basis of Classification? There are a few important characteristics that are regular to different organisms.
Kingdom Animalia: 1. Have multicellular eukaryote plants. Have multicellular eukaryote animals. 2. Presence of cell wall (made up of cellulose.) Absence of cell wall. 3. Capable of producing their own food (autotrophic mode of nutrition.) Depend on others for their food requirements (heterotrophic mode of nutrition.) 4.
The other four kingdoms, Protista, Fungi, Plantae, and Animalia are composed of all the eukaryotic organisms. Thus, the correct answer is option B. Q3. In the five-kingdom system of classification developed by R. H. Whittaker, members of the kingdom Animalia are heterotrophic, eukaryotic and A. Multicellular B. Motile C. Unicellular or ...
Characteristic Features of Phylum Chordata. They are bilaterally symmetrical and triploblastic. Chordates are coelomate and show an organ system level of organisation. They have the characteristic notochord, dorsal nerve cord, pharyngeal slits. In this phylum, the nervous system is dorsal, hollow and single.
Characteristics of members of kingdom Animalia are: They are multicellular organisms which do not possess chlorophyll. They are eukaryotic organisms. Cell wall is absent. Mode of nutrition is heterotrophic i.e. they depend on other organisms for food. They have muscle cells due to which they have the capability to contract and relax the body parts.
Q3. Kingdom Animalia is characterised by? Answer: The main criteria for classification used by Whittaker includes cell structure, thallus organization, mode of nutrition, reproduction and phylogenetic relationships. So, the absence of cell wall is one of the main characteristics of animal kingdom. Q4.
Characteristic Features of Phylum Porifera. They are generally marine aquatic organisms, with a few freshwater species. Their bodies are asymmetrical. Body shape can be cylindrical, vase-like, rounded or sac-like. They are diploblastic animals with two layers, the outer dermal layer and the inner gastral layer.
Characteristic Features of Phylum Mollusca. They are bilaterally symmetrical. They are triploblastic, which three layers. They show organ system grade of organisation. The body is soft and unsegmented. Body is divisible into three regions – head, a visceral mass, and ventral foot. Body is covered by a mantle and shell.
Give an account of Phylum Arthropoda. Answer: The phylum Arthropoda (Arthro- jointed; Podos-feet) contains the animals that have jointed appendages. They have the following characteristics: 1. It is the largest phylum of the animal kingdom. 2. These are bilaterally symmetrical, triploblastic and coelomate animals.
Kingdom-Animalia; Phylum- Chordata; Super-class-Gnathostomata; Class-Pisces; Characteristics . The characteristics of this class are-They have a streamlined body. The circulatory system is of close type. The body has three regions- head, trunk, and tail. The skeleton can be bony or cartilaginous. The sexes are separate.
