4. Interaction: we need to detect information from our
ENVIRONMENT and react. Examples, an animal defending their
territory.
Nutrition: we need to eat and taking essential NUTRIENTS.
Nutrients give us energy and enable us to grow. For example,
a bee eating polen.
Reproduction: living things can create new members of their
own species. There are different WAYS OF REPRODUCTION. For
example, plants reproduce from seeds, birds HATCH from
eggs.
EXTRA INFO!
5. Grupal exercise: in groups you will discuss about the
meaning of NUTRITION, INTERACTION and
REPRODUCTION. You will elaborate the meanings and
write them on your note book like this example:
Reprduction means…
Interaction means…
Nutrition means…
*Don’t forget to use the special words!!! Use as much English as
you can.
LET’S WORK TOGETHER
6. Interaction. We interact using our SENSES to detect
information and we use the language to communicate with
EACH OTHER.
Nutrition. We CARRY OUT nutrition drinking water and eating
food.
Reproduction. We make new BABIES and women produce milk
to FEED their babies.
HUMAN INTERACTION, NUTRITION AND
REPRODUCTION
8. Basic unit of life.
Carry out the basis life processes of
interaction, nutrition and reprodction.
They have many shapes and functions.
Let’s see them.
ANIMAL CELLS
9. ANIMAL CELLS
Nerve cells: star-shaped.
Transmit nerve impulses
from different parts of
the body to the brain
Red blood cells: flat and
circular. They carry
oxygen and nutrients
Reproductive cells: they
enable us to reproduce.
Female cells are
spherical and male cells
are oval with a long tail
10. PARTS OF AN ANIMAL CELL
NUCLEUS
CYTOPLASM
MEMBRANE
ORGANELLES
11. Nucleus:
controls everything that happens inside the cell.
Membrane:
surrounds and protects the cell.
Cytoplasm:
clear liquid protected by the membrane.
Other organelles:
can carry out functions of the cells, for example the nutrition.
PARTS OF THE ANIMAL CELL
12. Exercise 1: Copy these sentences on your notebook and say if
they are correct or not. Then discuss your opinion.
1. The nucleus is not inside the cell.
2. We have three types of animal cells.
3. Nerves cells transmit nerve impulses.
4. The animal cell only have three parts: the nucleus, the
membrane and the cytoplasm.
5. Red blood cells are circular.
LET’S WORK!!
14. They have rigid cell wall, usually rectangular or polygonal.
They are in charge of the PHOTOSYSNTHESIS, the process of
breathing of plants.
They have a green liquid called CHLOROPHYLL and a liquid
called SAP that is used to make food for the plant.
They have different parts. Let’s see them.
PLANT CELL CHARACTERISTICS
15. PARTS OF THE PLANT CELL
VACUOLE
NUCLEUS
MEMBRANE
CELL
WALL
16. Nucleus:
Controls everything that happens inside the cell.
Membrane:
Surrounds and protects the cell.
Cell wall:
Helps to support the plant.
Vacuole:
Stores food and water.
Other organelles:
Like chloroplasts that contain a green liquid called chlorophyll.
This liquid carries out photosynthesis.
PARTS OF THE PLANT CELL
17. Exercise 2. Copy the following sentences and fill the gaps with
one word.
1. The ________ stores water and food.
2. Plants cells have a __________ to support the plant.
3. The chlorophyll is a green ______ that carries out the
photosynthesis.
4. The ________ cells are inside plants.
LET’S WORK
18. Let’s work together!
Each group have to find some information about photosynthesis
at home and make a grupal meaning. You can ask your parents,
go to the library or search on internet.
Remember that you can use Spanish or English.
WHAT IS PHOTOSYNTHESIS?
19. When cells work together, they formTISSUES.
When tissues work together, they formORGANS.
When organs work together, they formSYSTEMS,
For EXAMPLE:
A MUSCLE CELL(flexible and strong) join with other to make
tissues forming MUSCLE TISSUE. Muscle tissue can form
organs like the HEART that PUMPS blood.
Groups of organs can work together for example the
circulatory system (made by blood), respiratory system
(breath), reproductive system (reproduction).
ORGANISATION OF ANIMALS
21. EXERCISE 3: The teacher will give you an piece of paper with
some systems. Write down the names of the systems. Here
you have a list of them. Try to guess their functions.
Digestive System
Respiratory System
Circulatory System
Muscular System
Skeletal System
Nervous System
Female reproductive System
Male reproductive System
LET’S WORK!
22. Plant cells are rigid and rectangular. They carry out the
process of photosynthesis thanks to a liquid called
chlorophyll.
When plant cells work together they form PLANT TISSUE.
Plant tissues work together to make PLANT ORGANS like a
leaf. The function of a leaf is absorb the SUNLIGHT and
DIOXIDE to produce food for the plant by photosynthesis.
SYSTEMS are formed by organs. We have flowers or roots.
HOW PLANTS ARE ORGANISED?
23. PARTS OF A PLANT
STEM: Support the plant
and transport water and
mineral.
ROOTS: Absorb water and
nutrients from the soil.
They have root hairs
24. In groups, you will make a poster to represent an
animal cell and a plant cell. You will label the parts,
the differences between them and explaining what
they form when they work together.
After finishing, you will explain with all details your
poster.
FINAL TASK
25. Use as much English as you can. Try to use the vocabulary
paper.
Try to find information on Internet to bring some at school to
make your presentation better.
Study the main parts in English and practice your explanation
at home and with your team.
TIPS!!!
