Structural organisation in animals class 11 notes

Table of contents Also, students can refer, • • And can be downloaded through the link NCERT Class 11 Biology Chapter 7 Notes Animal Tissues : A cell is the structural and functional unit of all living organisms. The group of cells is called tissues. There are mainly two types of tissues: plant and animal tissues. Each has its own specific functions. Animal tissues can be divided into four subtypes: • Epithelial tissue • Connective tissue • Muscular tissue • Neural tissue Epithelial Tissue Epithelial tissues act as a protective covering for the surfaces exposed to the environment and lining for the inner body cavities and internal organs. The cells are arranged in a dense manner with fewer intercellular spaces. This is again classified into two: Simple Epithelial Tissue The simple epithelium consists of single-layered cells. It protects the body cavities, internal organs, and ducts by acting as their lining. So the cells differ in their structure and therefore it is again divided into three types: • Squamous epithelium is flattened single-layered cells which protect the alveolar sac of the lungs and the walls of blood vessels and promote the diffusion of gases. • Cuboidal epithelium is cube-like single-layered cells that are found in the kidney tubules and ducted glands and are mainly concerned with absorption and secretion. • The columnar epithelium is tall single-layered cells that are found in the intestine and stomach and promote secretion and absorption. If the column...

Introduction It may surprise you to learn that all sophisticated organisms are made up of only four fundamental types of tissues. Solutions for NCERT class 11 biology chapter 7 structural organisation in animals contain interesting solutions that include an outstanding explanation of all questions about animals and their structural organisation. This topic introduces students to the various functions that animals are capable of performing. As a result, we have simplified the topic using examples that will improve your knowledge of the topic. So let's get started with this topic's tour. Structural organization in animals All species in the animal kingdom are multicellular, yet their cell arrangement does not follow the same pattern. Animal levels of the organization are categorized into the following categories based on cellular organization patterns: The cellular level of organisation: Cells in animals with this type of cell organisation are grouped in loose cell aggregates. Sponge organisation is a good example of this. Tissue level organization: Animal cells exhibit divisions in cell activities. Tissues are made up of cells that execute the same job. Coelenterates is one example. Tissues are an integrated set of cells that have similar cellular structures and execute similar tasks. In multicellular creatures, these tissues serve as a basic framework. Tissues are classified into four types: Epithelial tissue: The absence of blood vessels distinguishes epithelial tissues. ...

Systematic position Phylum : Annelida Class : Oligochaeta Genus : Pheretima Species : posthuma · Earthworm is a reddish-brown terrestrial invertebrate that inhabits the upper layer of moist soil. · During day time, they live in burrows made by boring and swallowing the soil. · Common Indian earthworms: Pheretima and Lumbricus. · Earthworms have long segmented cylindrical body. · Number of segments (metameres): about 100-120. · Dorsal surface has a dark median mid dorsal line (dorsal blood vessel) along the longitudinal axis of the body. · First segment (peristomium or buccal segment) bears the mouth. A lobe called prostomium covers the mouth. · Prostomium is sensory in function and is used to force open cracks in the soil into which the earthworm may crawl. · In a mature worm, segments 14-16 are covered by a dark band of glandular tissue called clitellum. · Body has 3 regions: preclitellar, clitellar & postclitellar. · 4 pairs of spermathecal apertures are found on ventro-lateral sides of intersegmental grooves (5 th -9 th segments). · A single female genital pore is present in the mid-ventral line of 14 th segment. · A pair of male genital pores is present on the ventro - lateral sides of the 18 th segment. · Many minute nephridiopores open on the body surface. · All segments except the first, last and clitellum bear S-shaped setae, embedded in the epidermal pits. Setae can be extended or retracted. Their function is locomotion.
