Content :

What are living things : Living things are things that have lives in them . They are alive and living . Examples of living things are mangoes , man , frogs ,fish , carrots , potatoes , maize , lizards etc

Plants as living things : Plants are living things because they can grow or germinate , produce seeds and flowers and die .Plants are green in colour due to the presence of the chlorophyll and are able to make  their own food with the help of sunlight, water and air. They are known for providing oxygen to the atmosphere.

Animals as living things : Animals are living things because they are alive and living . They can move eat and die later in life . Animals may be classified as wild animals and domestic animals . Wild animals are very dangerous and live in the wild while domestic animals are tame and live with us at home .

EXAMPLES OF DOMESTIC ANIMAL: Dog, goats, cow, cattle, rabbit etc

EXAMPLES OF WILD ANIMALS: Elephant,tigers,hyenas,lions ,snakes etc

Similarities between plants and animals 

They are both alive

Both plants and animals eat , feed or get nutrients

Animals and plants release gas into the atmosphere . Animals release carbon dioxide while plants release oxygen

Both plants and animals response to external stimulus or feeling

They both grow

They both die when the time comes

Difference between plants and animals 

Some animals have blood in them , plants do not have blood.

Some animals have skin or hair all over their bodies , plants do not have hair .

Some animals have scales all over their bodies , plants do not have scales

Some animals lay eggs , plants do not lay eggs

Animals are the living organisms which feed on the organic material and are known to have a specialized system in their body like the nervous system, reproductive system, sense organs, which make them unique from the other forms of life.

Movement

Plants do not have the ability to move from one place to another, as plants are rooted into the ground, exceptions are Volvox and Chlamydomonas. Animals can move from one place to another freely, and exceptions are Sponges and Corals.

Mode of nutrition

Plants have chlorophyll, due to which they have the capability to prepare their own food and are known as autotrophs.

Animals are the heterotrophs, as they depend on plants for their food, either directly or indirectly.

Storage of food

Plants do not have the digestive system, and the storage of food (carbohydrate) takes place in the form of starch. Animals have the proper digestive system which support the food in digesting and absorbing nutrition from it, the food (carbohydrate) is stored in the form of glycogen.

Respiration

Plants take in carbon dioxide and release oxygen into the atmosphere, exchange of gases occurs through stomata.

Animals take in oxygen and release carbon dioxide into the atmosphere, which occurs through lungs, gills, skin, etc.

Cellular structure

The cellular structure of plants contains the cell wall, chloroplast, plasmodesmata, plastids and other different organelles.The cellular structure of animals does not have cell walls, though other organelles like the tight junction, cilia are present.

Growth

The growth of the plants takes place throughout the life, the meristematic system present in the tip of roots and stems supports the growth.The organs and organ system supports the growth and is definite.

REPRODUCTION

Reproduction of plants takes place asexually like by budding, vegetative methods, spores, wind, or through insects.            Some lower animals like algae reproduce asexually while higher animals reproduce sexually.

Response

Plants show the response to stimuli like touch, light, though are less sensitive due to the absence of the sense organs. They have proper nervous system and response to any stimuli in a fraction of seconds, so they are regarded as highly sensitive.

Presentation :

The topic is presented step by step

Step 1:

The class teacher revises the previous topics

Step 2.

He introduces the new topic

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

Conclusion

The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.

Evaluation
