There is a unique level of diversity among living things in the living world. There's little doubt that ancient humans understood the difference between living things and non-living materials. A few examples of non-living or inanimate objects are fire, wind, and the sea.CBSE Class 11 Biology Notes Chapter 2: Biological Classification
Attempts to categorize living organisms have surely existed throughout human history. Humans used to classify things based just on instinct and no scientific standards. Aristotle was the first to attempt scientific categorization.CBSE Class 11 Biology Notes Chapter 3: Plant Kingdom
The Kingdom Plantae is referred to as the plant kingdom by experts. All plants on Earth are included in the kingdom of plants. Experts' knowledge of the plant kingdom has certainly changed over time.CBSE Class 11 Biology Notes Chapter 4: Animal Kingdom
A variety of animal species can be observed by simply looking around. These creatures also differ in their shapes and forms.CBSE Class 11 Biology Notes Chapter 5: Morphology of Flowering Plants
Flowering plants are discussed in Morphology of Flowering Plants, Class 11 Notes. It also explains why blooming plants vary greatly in terms of their size, form, nutrition, habitat, and life span.CBSE Class 11 Biology Notes Chapter 6: Anatomy of Flowering Plants
The chapter explains that several types of tissues make up plants. These tissues are also classified into two types, meristematic and permanent. These tissues also carry out several additional functions, including transporting water and minerals and digesting and storing food.CBSE Class 11 Biology Notes Chapter 7: Structural Organization in Animals
You have come across a wide range of creatures from the animal world in the previous chapters, including both unicellular and multicellular species. All of the body's functions, including digestion, breathing, and reproduction, are carried out by a single cell in unicellular organisms.CBSE Class 11 Biology Notes Chapter 8: Cells- The Unit of Life
The chapter shows that cells make up every type of creature, even non-living ones. The form, size, structure, and function of the cells also differ. They can be classified as eukaryotic or prokaryotic based on whether or not they have a membrane that surrounds the nucleus and other organelles.CBSE Class 11 Biology Notes Chapter 9: Biomolecules
The biology chapter on biomolecules in class 11 is very important. It exposes them to chemicals found in living things.CBSE Class 11 Biology Notes Chapter 10: Cell Cycle and Cell Division
