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

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.

7. Plants are: c) Multicellular living things
8. Plants are: a) Autotrophic living things
9. Animals are: c) Unicellular and multicellular living things
10. 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.
