EVOLUTION AND CLASSIFICATION

Evolutionary relationships of the species can be worked out by identifying hierarchies of their characteristics.

9. Heredity and Evolution | Class 10 CBSE | Web Notes | Part 3: Speciation

SPECIATION

Minor genetic changes occurring in a population is called microevolution. They change common characteristics of a species. It cannot explain formation of new species.

9. Heredity and Evolution | Class 10 CBSE | Web Notes | Part 2: Evolution

EVOLUTION

Sexual reproduction and errors in DNA copying lead to variation. Its consequences are illustrated below:

9. Heredity and Evolution | Class 10 CBSE | Web Notes | Part 1: Accumulation of Variation, Heredity

Heredity (inheritance) is the transmission of characters from parents to offspring.

Evolution is the change in the characteristics of a species over several generations.

8. How do Organisms Reproduce? | Class 10 CBSE | Web Notes | Part 4 | Sexual Reproduction in Human Beings

Reproduction in Human Beings

In early teenage, the appearance and proportions of body change and new features and sensations appear. These changes indicate the sexual maturation.

8. How do Organisms Reproduce? | Class 10 CBSE | Web Notes | Part 3 | Sexual Reproduction in Flowering Plants

SEXUAL REPRODUCTION


Why Sexual Mode of Reproduction?

It is the reproduction in which both sexes (male & female) are needed to produce new generations.

The errors during DNA copying creates variations.

8. How do Organisms Reproduce? | Class 10 CBSE | Web Notes | Part 2 | Modes of Reproduction Used by Single Organisms

MODES OF REPRODUCTION USED BY SINGLE ORGANISMS


The modes of reproduction by various organisms depend on their body design.

8. How do Organisms Reproduce? | Class 10 CBSE | Web Notes | Part 1 | Do Organisms Create Exact Copies of Themselves?

Reproduction is the production of offspring that are biologically similar to the parent organism.

7. Control and Coordination | Class 10 CBSE | Web Notes | Part 3 | Hormones in Animals

7. CONTROL AND COORDINATION

HORMONES IN ANIMALS (ENDOCRINE SYSTEM)


Electrical impulses can instruct only few tissues to prepare for an activity. So, in animals, there is another way of control & coordination called Endocrine system.

7. Control and Coordination | Class 10 CBSE | Web Notes | Part 2 | Coordination in Plants

7. CONTROL AND COORDINATION

COORDINATION IN PLANTS


Plants have no nervous system or muscles. But they can respond to stimuli.

7. Control and Coordination | Class 10 CBSE | Web Notes | Part 1 | Animals- Nervous System

7. CONTROL AND COORDINATION

In organisms, many movements are responses to changes in the environment or to use changes in environment. E.g.

6. Life Processes | Class 10 CBSE | Web Notes | Part 4 | Transportation

6. LIFE PROCESSES

TRANSPORTATION


It is the process of movement of water and other molecules to the concerned parts of the organism.

6. Life Processes | Class 10 CBSE | Web Notes | Part 5 | Excretion

6. LIFE PROCESSES

EXCRETION


Excretion is the process of removal of harmful metabolic nitrogenous wastes from the body.

6. Life Processes | Class 10 CBSE | Web Notes | Part 3 | Respiration

6. LIFE PROCESSES

RESPIRATION


It is the oxidation of the food material in cells to release energy for various life processes.

6. Life Processes | Class 10 CBSE | Web Notes | Part 1 | What are Life Processes?

6. LIFE PROCESSES

Organisms show many properties such as movement (growth-related or not). But the visible movement is not a defining characteristic of life because a plant may not grow visibly and some animals can breathe without visible movement.

6. Life Processes | Class 10 CBSE | Web Notes | Part 2 | Nutrition

6. LIFE PROCESSES

NUTRITION


It is the process of transfer of energy source (food) from outside the body to the inside.

5. Periodic Classification of Elements | Class 10 CBSE | Web Notes | Part 3 | Modern Periodic Table

 5. PERIODIC CLASSIFICATION OF ELEMENTS

 5. PERIODIC CLASSIFICATION OF ELEMENTS


MAKING ORDER OUT OF CHAOS – MENDELΓ‰EV’S PERIODIC TABLE


Dmitri Ivanovich Mendeleev (1834-1907, a Russian chemist) was the most important contributor to the development of Periodic Table.

5. Periodic Classification of Elements | Class 10 CBSE | Web Notes | Part 1 | Early Attempts of classification
