Theory • Classification: The organisms are classified/grouped based on the similarities (grouped together) and dissimilarities (grouped separately). • Whittaker classification: It has five kingdoms and these groups are formed on the basis of their cell structure, mode and source of nutrition and body organisation. The classification is given below. Further classification is done by naming the sub-groups at various levels as shown below: • Kingdom • Species: Group of organisms capable of inter-breeding to produce off-spring, e.g. species of dog. • Genus: Group of closely related species e.g. dog. • Family: Group of genus with common characters. • Order: Number of families with common characters. • Class: All similar orders are placed in a class. • Phylum/Division: Many classes with specific common characters. • Kingdom: All the organisms with same fundamental characteristics are in one kingdom. Plant Kingdom Thallophyta: (Thallus — undifferentiated; Phyta — Plant body.) • Plant body is thallus • Commonly called algae • Are all aquatic plants • These algaes make their own food by photosynthesis, e.g.Spirogyra. Bryophyta: • Amphibian plants • Plant body is commonly differentiated into stem and leaf like structures. • No specialised vascular tissue for conduction of water and other substances. e.g. Moss, Funaria. Pteridophyta: • Land plants with vascular tissues. • Plants body is differentiated into roots, stem and leaves. • These plants do not produce seeds. • Reproduce by sp...

Chapter 3 Plant Kingdom NCERT Solutions for Class 11 biology Chapter 3 Plant Kingdom The NCERT solutions for Class 11 Biology, Chapter 3 Plant Kingdom. This NCERT solution contains questions, answers, pictures and explanations for the complete Chapter 3 entitled Plant Kingdom from of Biology taught in Class 11. 1. What is the basis of classification of algae? Answer. Fritsch (1935), has classified algae considering phylogeny, affinities and inter-relationships of various forms. Algae are classified into three main classes – Chlorophyceae, Phaeophyceae, and Rhodophyceae. These divisions are based on the following factors: (a) Major photosynthetic pigments present (b) Form of stored food (c) Cell wall composition (d) Number of flagella and position of insertion 2. When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm? Answer. Liverwort –In liverworts, the main plant-body is haploid (gametophytic). It bears the male and female sex organs which produce gametes. These gametes fuse to form a zygote. The zygote develops on the gametophytic plant-body to form a sporophyte. The sporophyte is differentiated into the foot, seta, and capsule. Many haploid spores are produced as a result of the reduction division taking place inside the capsule. Moss –In mosses, the primary protonema (developed in the first stage) develops into the secondary protonema. Both these stages are haploid or gametophytic. The seconda...

He classified algae mainly on the basis of the characters like structure of plant body, nature of the pigments, reserve food material, number and position of flagella, chemistry of cell wall and methods of reproduction etc. Algae is divided into 11 classes but among them 3 main classes are Chlorophyceae, Phaeophyceae and Rhodophyceae. 2.When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm? soln.All of these plants show life cycle with one gametophytic (n) generation and one sporophytic (2n) generation. Reduction division or meiosis that produces haploid (n) cells from diploid cells (2n) is necessary in their life cycles to restore gametophyte generation after sporophytic generation. It occurs in different body structures according to the basic body design of these groups. Reduction division in a liverwort and moss takes place at the end of the sporophytic generation, where haploid spores ar...

Class 11 Biology chapter 3 notes will introduce you to the kingdom of plants. Plants are vital to all living things, as we will discover. Plant Kingdom Class 11 notes will also investigate how plants are classified or divided into groups based on their characteristics. The main topics covered in Class 11 Biology chapter 3 notes are Algae, Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms. All living organisms in the world have been categorized into groups by scientists. Table of contents The top three domains include two categories of extremely small organisms and a third called eukaryotes, which includes animals and plants. Kingdoms come after domains, and plants can take over an entire kingdom. The plant kingdom encompasses all living things. Plants have existed on the planet for millions of years, and there are hundreds of thousands of different species. Also, students can refer, • • NCERT Class 11 Biology Chapter 3 Notes NCERT Class 11 Biology Chapter 3 Plant Kingdom Notes-Topic 1: Introduction: Plantae now excludes fungi, as well as members of the Monera and Protista families with cell walls, despite previous classifications placing them in the same kingdom. As a result, cyanobacteria, also known as blue-green algae, are no longer considered algae. Let us examine classification within angiosperms to gain a better understanding of the concerns that influenced classification systems. The earliest classification systems relied solely on gross morphological characte...
