SUBJECT: BASIC SCIENCE
TERM: 3RD TERM
CLASS: PRIMARY 3
Subtitle: Comparison of plant and animals as living things
Learning Objectives: At the end of this this lesson, pupils should be able to:
Resources and materials:
Scheme of work
Instructional material: Specimen of animal in our locality.
Building Background/connection to prior knowledge: pupils are familiar with the topic in their previous classes.
Animals are classified as wild and domestic animal.
Domestic animals are animals that live with us at in our home,school compound and environment which we care for and they are not harmful to us. Domestic animals can also be called a friendly animal. While wield animals are animals that live in the bush. They are dangerous to human.
EXAMPLES OF DOMESTIC ANIMAL: Dog, goats, cow, cattle, rabbit etc
EXAMPLES OF WILD ANIMALS: Elephant,tigers,hyenas,lions ,snakes etc
BASIC COMPARISON OF PLANT AND ANIMALS AS LIVING THINGS
Plants are green in colour due to the presence of the chlorophyll and are able to prepare their own food with the help of sunlight, water and air. They are known for providing oxygen to the atmosphere. 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.
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.
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.
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.
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 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.
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.
