Class 11 Biology Annual Sample Question Paper 2020-21 (#class11Biology)(#eduvictors)(#cbsepapers)

Class 11 Biology Annual Sample Question Paper  2020-21

Learning is a continual process. To improve scores, the best way is to learn and practice. Solving question papers help students to evaluate their knowledge and familarise with different types of question patterns being asked in examination. 

Biology can primarily be divided into two separate branches. These branches are zoology and botany. Zoology comprises the study of animals, while botany consists of the study of plants.What is life? What are life processes? How do plants breathe? How living organisms are organised and classified, what the structure and functions of cells are, and all about the physiology of plants and human beings. The Class 11 Biology covers all these topics.

Eduvictors provides CBSE Previous Year Papers and Sample Question Papers for Class 11 Maths, Biology, Physics, Chemistry, English and Computer Science with/without solutions to help students in their board exam preparation.

1. CBSE New Pattern 15 Sample Paper Biology Class 11 for 2021 Exam with reduced Syllabus

Biology - Scientific Names (#Class11Biology)(#NEET)(#Class12Biology)(#Class9Biology)

 Biology - Scientific Names 

1. Swedish botanist Carolus Linnaeus established binomial nomenclature. 

2. Caper Bauhin expressed proposed binomial nomenclature for the first time 

3. In binomial nomenclature, the first word is a generic name having first letter capital and second word is a  specific epithet having first letter. e.g.  Homo sapiens, Mangifera indica

4. After end of biological name, the name of author is written in abbreviated form who gave the name to that organism.

5. Both the words of a biological name when handwritten are separately underlined and when printed are typed in italics to indicate their Latin origin and also give respect to the name.

An Overview of Virus and Viroids ( Q & A)

CBSE Class 11 Biology - The Living World 

Q1: Do five kingdom classification include viruses, viroids and lichens?

Answer: Five kingdom system of classification do not includes Virus, Viroids and Lichens.

Q2: What is a virus? What is its structure?

Answer: Viruses are non-cellular organisms having inert crystalline structure outside the living. A virus is a small particle consisting of a nucleic acid core surrounded by a protein coat; in order to reproduce, a virus must infect a living cell.

Class 9 - 12 - Biology - Know About Disease - Brief Notes About AIDS (#cbsenotes)(#eduvictors)

AIDS(A Brief Introduction)

Meaning of AIDS

✤ The word AIDS stands for Acquired Immuno Deficiency Syndrome. This means a deficiency of the immune system, acquired during the lifetime of an individual indicating that it is not a congenital disease [disease or abnormality present from birth]. ‘Syndrome’ means a group of symptoms.


✤ AIDS was first reported in 1981 and in the last twenty-five years or so, it has spread all over the world.

✤ Luc Montagnier, Françoise Barré-Sinoussi, and their colleagues at the Pasteur Institute in Paris were the first to report the discovery of the virus now called the human immunodeficiency virus (HIV) associated with AIDS.

Cell Biology - 7 Points about Plasmolysis

Plasmolysis vs Flaccid vs Turgid

1. When a living plant cell loses water through osmosis there is shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as plasmolysis
(plasma → fluid; lysis → disintegration, decomposition).


2. Only living cells, and not dead cells, are able to absorb water by osmosis.


3. Cell walls permit the cells of plants, fungi and bacteria to withstand very dilute [hypotonic] external media without shrinkage.

Nehemiah Grew - Father of Plant Anatomy

Nehemiah Grew (26 September 1641 – 25 March 1712) was an English plant anatomist and physiologist, known as the "Father of Plant Anatomy".

Nehemiah Grew (1641-1712) was practicing physician and worked as the secretary of the Royal Society, London. He began his work on the study of internal structure of the plants in the year 1664.

CBSE Class 11 - Biology - Understanding Plant Growth (#cbsenotes)(#eduvictors)

Understanding Plant Growth

Q1: Define growth.

Answer: Growth in an organism consists of a permanent and more or less irreversible increase in size, commonly accompanied by an increase in dry mass and amount of cytoplasm.


Q2: Define development.

Answer: The coordination of growth and differentiation of a single cell into multicellular tissues and organs is called development.


Q3: How the growth of living beings is different from non-living?

Answer: Growth in living beings is intrinsic or internal, in contrast to extrinsic growth observed in non-living objects.


Q4: How is plant growth different from animal growth?

Answer: Plant growth is generally indeterminate, i.e., continued throughout life while animal growth is non-continuous i.e. after a certain age, the ageing starts leading to death. In plants, the growth is diffused and localised while animal growth is uniform.


Q5: How plant growth is categorised?
