ANIMALS

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

BASOC 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.

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.

Characteristics of living things
There are seven activities which make organisms different from non-living things. These are the seven characteristics of living organisms.
1 Nutrition
Living things take in materials from their surroundings that they use for growth or to provide energy. Nutrition is the process by which organisms obtain energy and raw materials from nutrients such as proteins, carbohydrates and fats.
2 Respiration

Respiration is the release of energy from food substances in all  living cells. Living things break down food within their cells to release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but what about the thorn tree it sits in? Plants too move in various different ways. The movement may be so slow that it is very difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical reactions occurring in cells, they have to get rid of waste products which might poison the cells. Excretion is defined as the removal o toxic materials, the waste products of

metabolism and substances in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to produce new cells. The permanent increase in cell number and size is called growth.
6 Reproduction
All living organisms have the ability to produce offspring.

FORMS OF ENERGY

 (Heat) Energy

Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy.

Chemical Energy

Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas.

Nuclear Energy

Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity.

Electrical Energy

Electrical energy is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.

Radiant Energy

Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves.

Light Energy

Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.

Motion Energy

Motion energy – or mechanical energy – is the energy stored in objects; as objects move faster, more energy is stored. Examples of motion energy include wind, a flowing river, a moving car, or a person running.

Sound Energy

Sound energy is the movement of energy through substances. It moves in waves and is produced when a force makes an object or substance vibrate.

Elastic Energy

Elastic energy is a form of potential energy which is stored in an elastic object – such as a coiled spring or a stretched elastic band.

Gravitational Energy

Gravitational energy is a form of potential energy. It is energy associated with gravity or gravitational force – in other words, the energy held by an object.

LIGHT ENERGY

Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object’s atoms heat up. Light travels in waves and is the only form of energy visible to the human eye.
