Chapter 1 The Living World helps students to learn and identify the world of living. Students can find in it the definition of what is Living? Classification of organisms (Taxonomic) and more. Studying these enables students to gain a higher interest in this subject and enables them to answer the questions based on the illustrated topics.
In Biology there are five kingdoms: animal, plant, fungi, protista and monera. All of these are the core of our living world about which you will study in this class. However, the current exercise will aid you in understanding the concepts of these kingdoms along with the classification.
After giving the information of kingdom classification this exercise aids students in understanding the plant kingdom. In order to learn about the plant kingdom, one of the best ways is to refer to the NCERT Class 11th biology books. Through this lesson learners will be able to learn about the plant classification into various parts along with that they will learn about Algae, Bryophytes, Pteridophytes, and much more.
If we look in our surroundings, we find various kinds of animals, they are different by their shape or structure, colours, behaviour and more. Hence, it becomes one of the most important things for us to categorise the animal kingdoms too. This chapter is dedicated to allow you to learn about the various categories of animals which have been discovered earlier and about those which are newly discovered.
This chapter helps students to learn about the standard terms and definitions they need to know in order to have a better grip on this subject. Morphology is known as the study of shape/structure, in short morphology is the branch of science where students learn about the form of things. In chapter 5 the title is Morphology of Flowering Plants. Meaning it guides students to learn about the root, stem, leaf, inflorescence, flower, fruit, seeds and more.
Through this chapter students will be able to learn about the internal structure of plants where they will be knowing about their unit cell, tissue, and more. With the help of anatomy of flowering plants, students will also be able to learn about the adaptations to diverse environments.
Processes such as digestion, respiration and reproduction are performed by a single cell in unicellular organisms. However, in multicellular animals, the exact functions are held by many different cells. All animals or complex animals carry 4 fundamental organs: stomach, lung, heart and kidney. In order to score good marks in this chapter, you can refer to the solutions.
All humans, animals or any organisms are made up of cells. So, the basic building block of living organisms is cells. This chapter has explained the basic unit of life that is the cell. In this exercise students will be able to learn about the various cells, whether it is animal cells, plant or human cells.
Chapter 9 caters the topics of biomolecules in a systematic manner, where all the important topics, structure and more have been elaborated properly. Through this chapter, students will be able to gather the information related to the structure and function of proteins, Enzymes- types, properties and more.
This chapter explains the fundamental concepts of cell growth and division. Through this exercise the pupils gain in depth knowledge and it further allows them to have a proper understanding of the given topic. Also, having proper knowledge in this chapter enables students to learn about the various interesting things and allows them to score good marks in the exam with ease.
Plant-Water Relations, Long Distance Transport of Water, Transpiration, etc. have been elaborated throughout this exercise where students have chances to learn about the plants in a bit detail. This chapter is dedicated to allow students to gather the information related to the vascular system in higher plants, transport of food, and more.
In order to obtain the growth in plants they need necessary minerals and nutrition. This exercise explains them in a bit detail along with other concepts as well such as how food is transported and absorbed. Further, the minerals deficiency has been also elaborated and the way how we can identify them that a plant has minerals deficiency.
Photosynthesis is one of the core functions of a leaf in a plant. Just like humans and animals to survive in this ecological system the plants need their food which is being prepared by the green leafs in the presence of sunlight. This chapter is devoted to allow students to learn about photosynthetic mechanisms and how a light energy transforms into a chemical energy through the Photosynthesis in Higher Plants.
Up To this point the students are expected to have a better understanding of the term photosynthesis and respiration. Thus, this chapter later explains the new terminology through this lesson such as aerobic and anaerobic respiration, glycolysis, fermentation, and more. This exercise is very interesting as it's questions are quite interesting too. Questions such as do plants breathe? Have been elaborated too.
Plant growths are impacted via various kinds of internal and external factors. Through this, Plant development phases, growth regulators, differentiation, etc. will be elaborated. It will also assist students to gather the information about the plant hormones and their contributions in plant growth. In the NEET medical entrance exam, this topic has 6 percent of weightage.
Food digestion is one of the most crucial processes in a human body, in order to digest food, the body and its parts have to perform various functions which has been explained through this exercise. Not only the digestion but the nutritional components, and Digestive system disorders are also briefly illustrated in it.
While breathing and passing the gases, the two types of gases are involved, hence this chapter is dedicated to allow students to learn about the respiratory system and the organs. Movement and exchange of oxygen and carbon dioxide is being discussed in this chapter too. Further, it allows students to learn about various respiratory system diseases.
Just like the consumption of food, nutrition, and oxygen, it is important for the body to release the waste substances from the body. In this chapter the organisation and properties of blood and lymph, as well as the mechanism of blood dispersion have been discussed.
Human Excretory System, Urine Formation, Regulation of Kidney Function, etc. have been discussed in this lesson. Through this lesson, the students will be able to learn about various important components of the excretory system in humans. Apart from these things, the students get to learn about various kinds of kidney disorders.
Locomotion is the ability of movement from one place to another. In order to relate locomotion to real life you can consider the examples of climbing, flying, and swimming, etc. Movement is considered as one of the most important features in a living creature. Animal movement can be changed according to change in their habitats and situations.
In order to run the human body smoothly our body parts communicate with each other through neural controls. The coordination is the mechanism through which at least two organs interact. Through this chapter, the students are made knowledgeable about the neural system of humans. There are many neural coordinating tools: nerve impulse transmission, impulse conduction across a synapse, and the physiology of reflex response.
Two different terms are elaborated in this chapter: endocrine and exocrine glands. Endocrine is related to a gland that secrete hormones or other products directly into the blood. Whereas, exocrine glands are those who secrete the hormones through ducts opening onto an epithelium instead of bloodstream. In the final examination this chapter has a total of 18 points.
CBSE Class 11th Biology syllabus has been divided into two to allow students to easily grasp the concepts. With the division in the syllabus, the students have become more efficient to cover vast areas in the subject so that they can have a good grasp on the given topics.
