It is important that in class 11, students pay attention to what is being taught because it sets the base for their board examinations the next year. We provide up to date biology notes for class 11 that is prepared after scrutinising the previous years' question papers and updating the latest syllabus.

Our Biology notes for class 11 free PDF download is made with the best interests of the students in mind. It is important that students can score well and complete their paper on time so that they can go through their answers before submission. This means that they need to be up to date with their syllabus and our revision notes does exactly that. The CBSE biology chapter wise revision notes for class 11 ensures that they have their notes in the right order for them to choose and study.

The Biology notes are comprehensively laid out for you to choose exactly which chapter you want to focus on. The CBSE class 11 biology revision notes are also updated so that they focus on topics that have a higher probability of appearing in the examinations.

Since you might not have time to study all the contents of the textbook, you can refer to these revision notes to make the process simpler for you.

Further, the Biology notes for class 11 PDF free download is prepared by teachers who have many years of teaching experience. They have added little tips and tricks to ensure that you do not fall short of scoring exactly what you are looking for.

What our students say

Biology is a subject that requires a lot of practice owing to the different diagrams and structures that need to be studied. Now if you have difficulty in Physics, Chemistry, Maths or Biology, you could try our online coaching services for an affordable fee, right at the comfort of your home.

With one teacher for every students, your doubts may be a hindrance to the class flow in a coaching institute. While some have a doubt session after class, the long line of students asking their doubts before your turn is a waste of time. We at Vedantu understand that your time is valuable and take pride in our ability to give you a personalised class with which you can guarantee success.

Would recommend. Gabe They all have amazing life experiences and They all have amazing life experiences and they're just really interesting people to learn from. Prima Sutandyo Shabrina Yusri The atmosphere is really chill, they have snacks if that's what you need to keep you energised!!

Your tutor is basically your friend, and it makes asking questions both in-class and out of class through text much easier. Synergy is the only tutor I've ever gone to and I don't regret it - I don't know what I would've done without them.

These are:. This essentially relates back to Module 5 in terms of genetic variation and the continuity of species. By lowering the biodiversity, you will decrease the genetic variation and vice versa. If a species population have low genetic diversity or variation it would be susceptible to extinction upon changes in ambient environmental selective pressures. Thus, the genetic diversity and biodiversity is critical to the continuity of the species as we have already explored in detail in Module 5 Notes.

These include food beef, lettuce, fish meats, etcmedicine e. There a decline in species diversity would mean the availability of such food, medicine penicillin from fungus and common substances may be reduced or completely removed. The last component of biodiversity is ecosystem diversity.

As mentioned in the definition earlier, ecosystem diversity provides abiotic components such as circulation and purifying air, water, erosion control, water level control as well as fertile land for agricultural purposes. The destruction of natural ecosystems will result in a decline in not only species and genetic diversity thus biodiversity of the organisms residing in such habitats, but important those abiotic components in sustaining life. For example, rainforests are critical in not only providing oxygen for terrestrial and aquatic organisms to perform cellular respiration but also in maintaining the CO2 level in the atmosphere.

This is important as the level of carbon dioxide in the atmosphere will have any effect on the temperature on Earth. The enzymes in living organisms are sensitive to temperature and thus extreme temperatures would hinder the operations of metabolic processes and can result in death.

It is now clear that preserving biodiversity is important.

It should also mentioned that tourists travel around the world each year to explore natural landscapes such as rainforests which are a large source of revenue for many countries. As we have defined earlier, biotechnology refers to activities involving living cells particular involving the use of organisms or their materials as tools or for commercial use.

Moreover, past biotechnology techniques also focused on using microbes to manufacture beer, wine, cheese, bread and many more. However, as time passed, the use and purpose of biotechnology evolved which we will refer to modern biotechnology which we will refer to biotechnology from this point onwards.

Modern biotechnology deals mainly with cellular molecules with DNA.

There is only one reason to why biotechnology works. That is, DNA nucleotides. The process of producing a transgenic species starts with the identification of the desired gene to be inserted into an organism.

The extraction process involves using a gene splicing technique in recombinant DNA technology. Note that polymerase chain reaction PCR is often used to make multiple copies of the gene which is inserted into each plasmids to allow larger quantities of the gene to be produced. By adding heat to a solution containing the modified plasmid and E coli bacteria, the bacteria will absorb the plasmid into its DNA whereby the plasmid can be copied as the bacteria reproduces in a nutrition rich environment with antibiotics.

Note that the plasmids have naturally genes for antibiotic resistance.

Since the nutritional environment in which the bacteria is cultured contains antibiotics, any bacteria that does not absorb the plasmid containing antibiotic resistant gene will be killed. Thus by adding antibiotics in the culture environment, it ensures all surviving old and new bacteria carry the desired gene. This allows multiple copies of the recombinant DNA to be produced by the bacteria in some cases yeast is used instead. The recombinant DNA can be inserted into a host species to convert it into a transgenic species.

It is important to note that these organisms involved in the DNA recombination process do not need to be related and the technique allows favourable characteristics from one individual to be also be exhibited in another individual may or may not be the same type of species. This process is selective as the gene that specifies for the favourable trait can be extracted.

In reality, manufacturers make GM food and transgenic food synonymous despite them being different! Fun Fact: Other methods to produce transgenic species include: DNA microinjection, embryonic stem-cell mediated gene transfer, retrovirus-mediated gene transfer, electroporation, etc.

For example, through recombinant DNA technology, biotechnologists use a restriction enzyme to cut DNA segments in jellyfish that are responsible for their glow-in-the-dark feature and the same restriction to cut out same section of DNA from rabbits.

We will be focusing on medical, agricultural and marine biotechnology for HSC Biology. Fast forwarding to BC, some common crops that we see in modern civilisation including potatoes and peas are seen to be grown in America and Eurasia.

Ancient fermentation of grapes to produce wines were also common. His experimental results led to his proposal of the three major laws of inheritance being — dominance, independent assortment and random segregation, officially marking the birth of genetics studies.What is living?
