THE MAIN CHARACTERISTICS OF LIVING THINGS ARE:

They are born All living things are born from another living thing.

They eat All living things need food to eat.

They grow All living things increase in size during their lifetime. Sometimes they change in appearance.

They react Living things can perceive what is going on around them, and they react to what they perceive.

They reproduce Living things can create offspring similar to themselves.

They die Living things stop functioning and cease to live.

Activity 6. Read the following text, underline the words in bold and match them with the definitions

WORDS DEFINITIONSSensitivity process Living things perceive what is happening around them. Living things react to what they perceive.

Heterotrophic living things Living things that eat other living creatures.

Sensitivity process Thanks to this process, humans can use their sense organs to perceive what is happening around them and react.

Autotrophic living things Living things that eat inorganic substances (water, minerals and gases).

Reproduction process Living things can have offspring with their same characteristics.

Nutrition process Living things ingest food substances, transform them into nutrients and eliminate waste substances.

Activity 7. Read the text again and choose the correct answer

1. We can divide living things into two groups depending on how they get nutrients: a) Heterotrophic living things and autotrophic living things

2. Heterotrophic living things eat: c) Other living creatures

3. Autotrophic living things: b) Make their own food

4. Thanks to reproduction: a) Living things reproduce and have offspring with their same characteristics

5. Thanks to sensitivity: b) Living things perceive what is happening around them

6. Thanks to nutrition: c) Living things ingest food substances, transform them and eliminate waste substances

7. Humans beings use their sense organs: a) To perceive what is happening around them and react

8. Living things can have offspring: a) With their same characteristics

9. Most living things: b) Need another living thing to reproduce

10. There are: a) Three basic life processes

Activity 8. Listen and complete the text about the three life processes

The three life processes are: nutrition, sensitivity, and reproduction.

1. Nutrition: Living things ingest food substances, transform them into nutrients and eliminate waste substances. Food contains essential nutrients that are used by living things to grow and get energy to carry out life processes.

Living things can be heterotrophic living things if they eat other living creatures or autotrophic living things if they make their own food.

2. Sensitivity: Living things react to what they perceive. Thanks to this function, humans can use their sense organs to perceive what is happening around them and react. For example, animals can look for food and escape when they perceive danger.

3. Reproduction: Living things can have offspring with their same characteristics. Many living things need another living thing to reproduce. When male and female living things reproduce, they make new living things similar to themselves.

WHAT IS A CELL?

Living things are made up of millions of very small units called cells.

A cell is the smallest living unit which makes up a living thing.

The number of cells in a living thing varies. Some living things are made up of a single cell, so we call them unicellular. Other living things are made up of many cells, so we call them multicellular.

Cells are living things, so they carry out the three life processes: nutrition,sensitivity and reproduction.

Cells have three parts: a membrane, a nucleus and a cytoplasm.

In multicellular living things:

Cells form tissues.Tissues form organs. Organs are made up of a group of tissues that work together to carry out a common function. For example, muscles are organs.Organs form systems. Systems are made up of a group of organs that work together to carry out a common function. For example, the digestive system, the musculoskeletal system or the reproductive system ...Systems form organisms. An organism is a complete living thing.

Activity 17. Listen and circle the correct answer

1. Monerans are: a ) Unicellular living things2. Monerans are: c) Autotrophic living things and heterotrophic living things3. Protists are: c) Unicellular and multicellular living things4. Protists are: a) Autotrophic living things5. Fungi are: c) Unicellular and multicellular living things6. Fungi are: b) Heterotrophic living things7. Plants are: c) Multicellular living things8. Plants are: a) Autotrophic living things9. Animals are: c) Unicellular and multicellular living things10. Animals are: b) Heterotrophic living things

Activity 18. Read the following text and correct the mistakes you can find in them.

Monerans are unicellular living things. They have one single cell without nucleus. They can live in different environments. They are autotrophic and heterotrophic living things.

Protists are unicellular and multicellular living things. They live in water. They are autotrophic living things.

Fungi can be unicellular or multicellular living things. Fungi are usually found underground, on pieces of wood or on decomposing food. They are heterotrophic living things.

Plants are multicellular living things. They are autotrophic living things. They do not have sense organs neither nervous system. They can react to stimuli.

Animals are multicellular living things. They are heterotrophic living things. They can move and they have a nervous system and sense organs that allow them to react to stimuli quickly.
