Chapter 4 Animal Kingdom Class 11 NEET Biology deals with:
Classification of animals is the action of classifying the animals based on similar characteristics.
As over a million species of animals have been described till now, the need for classification becomes important.
The classification also helps in assigning a systematic position to newly described species.
Features such as arrangement of cells, body symmetry, nature of coelom, patterns of digestive, circulatory or reproductive systems are the basis of animal classification.
Levels of Organisation
- Cellular level of organization- cells are arranged as loose cell aggregates. Example- Sponges
- Tissue level of organization- cells performing the same function are arranged into tissues. Example- coelenterates.
- Organ level of organization- tissues are grouped together to form organs, each specialized for a particular function. Example- Platyhelminthes
- Organ system level of organization- organs have associated to form functional systems, each system concerned with a specific physiological function. Example- Annelids, Arthropods, Molluscs, Echinoderms and Chordates.
Complexities can be seen in animals with organ system level of organization.
For example-i) the digestive system in Platyhelminthes has only a single opening that serves as both mouth and anus, and is hence called incomplete digestive system, whereas a complete digestive system has two openings, mouth and anus.
ii) open type circulatory system is the one in which the blood is pumped out of the heart and the cells and tissues are directly bathed in it or ,whereas closed type is the one in which the blood is circulated through arteries, veins and capillaries.
Symmetry
- Asymmetrical- when any plane that passes through the center does not divide them into equal halves. Example- Sponges.
- Radial symmetry- When any plane passing through the central axis of the body divides the organism into two identical halves. Example- Coelenterates, Ctenophores etc.
- Bilateral symmetry- When the body can be divided into identical left and right halves in only one plane. Example- Annelids, Arthropods, etc.
Diploblastic and Triploblastic Organisation
- Diploblastic animals- Animals in which the cells are arranged in two embryonic layers, an external ectoderm and an internal endoderm. Example- coelenterates
- Triploblastic animals- Animals in which the developing embryo has a third germinal layer, mesoderm, in between the ectoderm and endoderm. Examples- platyhelminthes to chordates
Coelom
- The body cavity, which is lined by mesoderm is called coelom.
- Animals possessing coelom are called coelomates. Examples- annelids, molluscs etc.
- The body cavity is not lined by mesoderm, instead, the mesoderm is present as scattered pouches in between the ectoderm and endoderm, such a body cavity is called pseudocoelom and the animals possessing them are called pseudocoelomates. Examples- Aschelminthes
- The animals in which the body cavity is absent are called acoelomates. Examples- Platyhelminthes
Segmentation
Segmentation is the process of dividing the body externally and internally into segments with a serial repetition of at least some organs.
For example- In earthworm, the body shows called metameric segmentation and the phenomenon is known as metamerism.
Notochord
- Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development.
- Animals with notochord are called chordates and those animals which do not form this structure are called non-chordates. Examples- porifera to echinoderms.
Types of classification
- Animals are classified based on arrangement of cells, body symmetry, nature of coelom, patterns of digestive, circulatory or reproductive system.
- Animal kingdom is classified into various phylums such as Phylum Porifera, Phylum Coelenterata (Cnidaria), Phylum Ctenophore, Phylum Platyhelminthes, Phylum Aschelminthes, Phylum Annelida, Phylum Arthropoda, Phylum Mollusca, Phylum Echinodermata, Phylum Hemichordata and Phylum Chordata.

Always remember, it is very important to study with full concentration during Revision. Here are a few tips for you on how to revise with full focus:
- - Create a Distraction-Free Environment: Find a quiet and comfortable place to study where you can minimize distractions. Turn off or silence your phone, log out of social media accounts, and inform others around you that you need uninterrupted study time. A dedicated study environment will help you focus better.
- - Set Specific Goals: Before starting your study session, set clear and achievable goals. Break down your study material into smaller tasks, and plan what you want to accomplish during each session. Having specific goals will give you a sense of direction and purpose, making it easier to concentrate.
- - Use the Pomodoro Technique: The Pomodoro Technique is a time management method that involves studying in short, focused intervals, typically 25 minutes, followed by a short break of 5 minutes. After completing four sessions, take a longer break of around 15-30 minutes. This technique can improve focus and productivity by providing regular breaks to recharge.
- - Stay Organized: Keep your study materials, notes, and resources well-organized. Having everything you need at hand will save time and reduce distractions caused by searching for materials. Use color-coded folders or digital tools to maintain a structured study system.
- - Practice Mindfulness and Meditation: Before you begin studying, take a few minutes to practice mindfulness or meditation. Deep breathing exercises and clearing your mind of distractions can help you approach your study session with a calm and focused mindset.
- Remember, studying with full concentration is a skill that takes time and practice to develop. If you find your mind wandering during study sessions, gently bring your focus back to the task at hand and be patient with yourself. With consistent effort, you can improve your ability to concentrate and make the most of your study time.
