Biology Syllabus for Class 12 CBSE
My brother is 12th Biology standard student of CBSE, so right now he needs the 12th Bio syllabus, so tell me from where I can download? Here i am attaching the pdf of the Biology Syllabus for Class 12 in CBSE. In PDF has syllabus of One Paper which is having the unit as Reproduction Genetics and Evolution Biology and Human Welfare Biotechnology and its Applications Ecology and Environment Some content of PDF is showed as below 1. Reproduction Reproduction in organisms: reproduction, a characteristic feature of all organisms for continuation of species; asexual reproduction modes of reproduction - asexual and sexual reproduction; modes - binary fission, sporulation, budding, gemmule, fragmentation; vegetative propagation in plants. Sexual reproduction in flowering plant: flower structure; development of male and female gametophytes; pollination - types, agenci For more syllabuses you can read out the attach PDF as below:- Last edited by Neelurk; February 29th, 2020 at 08:20 AM. |
