Podéis descargarlo y, o bien imprimirlo (si podéis), o bien copiarlo en el cuaderno.

Cuando terminéis, hacéis una foto y me la mandáis. TENÉIS HASTA EL MARTES DÍA 12.

IMPORTANTE:

• Por favor, haced una foto con luz suficiente y sin que haya sombras.
• Acercaos todo lo posible para que la letra no se vea pequeña y desenfocada.

NUCLEUS

It controls the functions of the cellm such as reproduction.

CELL MEMBRANE

It controls what enters and leaves the cell.

CYTOPLASM

It's a jelly-like substance in he cell where chemical reactions happen.

VACUOLE

It contains water and minerals, which the organism needs in order to grow.

CHLOROPLASTS

It contains chlorophyll, which is needed during photosynthesis.

WALL CELL

It's a rigid wall which protects the cell and gives it the shape.

NUTRITION

All living things obtain nutrients from their environment and transform them into energy. This energy allows them to live, grow and develop. Different organisms get their energy via different processes:

• Plants produce their own food through photosynthesis.
• Animal can't produce their own food so they feed on other living things.
• Decomposers, such as fungi and bacteria, feed on the remains of dead plants and animals.

REPRODUCTION

This process allows living things to produce new organisms similar to them. Reproduction can be sexual or asexual:

• Asexual reproduction occurs when only one organism is required, as is the case of bacteria.

• In sexual reproduction, two different types of individual are required: male and female.

INTERACTION

All living things interact with their environment. A change in the environment can cause a reaction. We call this change a stimulus, and the reaction, a response. Animals use their sense organs to detect some stimuli. Most plants have no sense organs but they react to stimuli too.

Living things can be classified into a five groups called kingdoms. Organisms of the same kingdom share similarities and are different from organism in other kingdoms.

ANIMAL KINGDOM

Animals are milticellular. They can't make their own food, so they get the energy they need to survive by feeding on other living things. Most animals have the ability to move.

PLANT KINGDOM

Plants are multicellular. They make their own food through the process called photosynthesis. During it, plants absorb dioxide and release oxygen.

PROTIST KINGDOM

Protists are usually unicellular, but some are multicellular. Most protists are found in water.

The amoeba is an unicellular protist which takes in its food by absorbing it through the cell membrane.

Algae are protist that can be unicellular or multicellular. They also make their own food through photosynthesis.

FUNGUS KINGDOM

Fungi can be unicellular or multicellular. Fungi can't make their own food. They obtain the nutrients they need from the remains of dead plants and animals.

MONERA KINGDOM

All organisms in this kingdom are unicellular. They can be found on land, in the air, in water and inside ither living things. Bacteria belong to the monera kingdom. We some bacteria to make food, such as cheese and yoghurt. Some bacteria feed on dead plants and animals.
