BIOLOGY -CONTENTS OF CLASS XI SYLLABUS

UNIT I: Diversity in Living World

    

Details:

• What is living? ; Biodiversity; Need for classification; Three domain of life;  Taxonomy & Systematics; Concept of species and taxonomical hierarchy;  Binomial nomenclature; Tools for study of Taxonomy – Museums, Zoos,  Herbaria, Botanical gardens.

• Five kingdom classification; salient features and classification of Monera; Protista and Fungi into major groups; Lichens; Viruses and Viroids.

 

•  Salient features and classification of plants into major groups-Algae, Bryophytes,  Pteridophytes, Gymnosperm and Angiosperm (three to five salient and  distinguishing features and at least two examples of each category); Angiosperms-  classification up to class, characteristic features and examples).

•  Salient features and classification of animals-non-chordate up to phyla level and  chordate up to classes level (three to five salient features and at least two

examples).

UNIT II: Structural Organisation in Animals and Plants 

Details:

•  Morphology and modifications; Tissues; Anatomy and functions of different parts  of flowering plants: Root, stem, leaf, inflorescence- cymose and recemose,  flower, fruit and seed (To be dealt along with the relevant practical of the  Practical Syllabus).

• Animal tissues; Morphology, anatomy and functions of different systems  (digestive, circulatory, respiratory, nervous and reproductive) of an insect  (cockroach). (Brief account only)

UNIT III: Cell Structure and Function    

Details:

•  Cell theory and cell as the basic unit of life; Structure of prokaryotic and  eukaryotic cell; Plant cell and animal cell; Cell envelope, cell membrane, cell  wall; Cell organelles-structure and function; Endomembrane system-endoplasmic

reticulum, Golgi bodies, lysosomes, vacuoles; mitochondria, ribosomes, plastids,

micro bodies;  Cytoskeleton, cilia, flagella, centrioles (ultra structure and  function); Nucleus-nuclear membrane, chromatin, nucleolus.

•  Chemical constituents of living cells: Biomolecules-structure and function of  proteins, carbodydrates, lipid, nucleic acids; Enzymes-types, properties, enzyme  action.

•  B Cell division: Cell cycle, mitosis, meiosis and their significance.

UNIT IV: Plant Physiology

      

Details:-

•  Transport in plants: Movement of water, gases and nutrients; Cell to cell  transport-Diffusion, facilitated diffusion, active transport; Plant – water relations  – Imbibitions, water potential, osmosis, plasmolysis; Long distance transport of  water – Absorption, apoplast, symplast, transpiration pull, root pressure and  guttation; Transpiration-Opening and closing of stomata; Uptake and  translocation of mineral nutrients-Transport of food, phloem transport, Mass flow  hypothesis; Diffusion of gases (brief mention).

•  Mineral nutrition: Essential minerals, macro and micronutrients and their role;  Deficiency symptoms; Mineral toxicity; Elementary idea of Hydroponics as a  method to study mineral nutrition; Nitrogen metabolism-Nitrogen cycle,  biological nitrogen fixation.
