Solution

Characteristics

Living Things

Non Living Things

Shape and Size

They possess definite shape and sixe

No definite shape and size

Cellular structure

They consists of cells

They have no cells

Organisation

Have a definite organisation. There are tissues, organs, organ systems which work as an integrated unit

No organisation

Growth

They show growth

No growth

Movement

They show movement or locomotion

No movement

Nutrition

Need food for energy

Need no food

Respiration

All living organism respire.In order to obtain energy, glucose is combine with oxygen in cells.

Need no respiration

Excretion

Excrete unwanted materials from the body

Do not show excretion

Metabolism

Anabolic and catabolic reactions takes place.

No metabolic changes takes place

Response

Show response to stimuli

Show no response to stimuli

Reproduction

Reproduce young ones of their own kind

Show no reproduction

Differentiation

Show differentiation during development

No process of differentiation takes place

Adaptations

Living things show adaptations to changing environmental conditions for better survival

Do not show any adaptations

Life span

Living things have some life span.

They have no life span

Death

Living beings will die after certain period of life.

Death doesn’t exsist in these things. They are broken down or destroyed by external forces

Examples

Human, birds, tree etc.

Car, pen, chair etc

2.

Eight criteria of life are:

i) These all above criteria present into snail but absent in rock.

ii) These above eight criteria present in tree but absent in rock.

iii) These above criteria present in dog but absent in TV.

3.

Electricity is sometimes called live because it uses a shock that can go through our whole body and shock us.

For example:

1. Reflex arc.

2. An electrical signal always generate from our heart and maintains our blood circulation.
