Living things.

Living things: There are three vital functions: 1º: Nutriction means to get nutrients from the food. 2º: Reproduction means making new living things.3º: Interaction means to react to changes of the enviroment.Types of living things: Animals, plants, bacteria, fungi and algae.

Non-living things.

Non-living things: They are not born, they do not grow, they do not reproduce and they do not die.

1º part of Nutrition.

What is nutrition? Nutrition is to obtain nutrients from the enviroment and transform them into energy.

How do plants do it? Plants produce their own food through photosynthesis and they need: water and minerals, sunlight and carbon dioxide.

2º part of Nutrition.How do animals do it? Animals feed on other living things and they can be: Carnivores eat other animals, hervivores eat plants and omnivores eat plants and other animals.

How do fungi and bacteria do it? Fungi and bacteria feed on the remains of dead animals and plants.

Reproduction.What is it? Reproduction means making new living things.

Types: Asexual and sexual. In asexual reproduction one individual is needed, for example: sea start, bacteria, pine apple, etc…

In sexual reproduction two individuals are needed: male and female.

Interaction.

What is it? In interaction there is a change and there is a reaction.

Elements: Stimulus is the change and response is the reaction.

Cell.

What is it? It is the smallest part in which living things are divided.

Structure: Many cells make tissues, many tissues make organs, many organs make systems and many systems make organisms.

Nucleous.

It is a part of the cell that controls the functions of the cell. It is like a Town Hall in a city.

Cell membrane.

It is a part of the cell that controls what enters and leaves the cell. It is like a group of guards.

Cytoplasm.

It is a subtance where all parts of the cell float around. It is like the atmosphere of a city.

Vacuoles.

It is a part of the cell that contain water and minerals for the cell. They are like reservoirs in a city.

Cell wall.

It is a part of the cell that protecs the cell. It is like the city wall.

Chloroplast.

It is a part of the cell that contain chlorophyll which plants need for photosynthesis. They are like parks in a city.

Unicellular organisms.

They only have one cell, for example: bacteria.

Multicellular organisms.

They have more than one cell.

Microscope.

It is a instrument that we need to see things bigger.

From Cell To Organisms.

Some cells: Red Blood Cells, White blood cells, Nerve Cells, Root hair

Cell, Leaf Cells and Plateletes.

Red Blood Cells.

They carry oxygen to all parts of the body.

White Blood Cells.

They carry information and connections between cells grow as we learn things.

Root Hair Cells.

They absorb water and minerals from the soil.

Leaf Cells.

They collect sunlight for phtosyntesis.

Plateletes.

When there is an injury in a blood vessel, they close that injury.

Tissues.What are they made up of? They are made up of a number of cells working together that carry out a particular function.

Examples: Xylem, muscle, tissue, etc…

Organs.What are they made up of? They are made up of a nuber of tissues working together that carry out a particular function.

Examples: Heart, lungs, stomach, brain, veins, etc…

Systems.What are they made up of? They are made up of a number of organs working together that carry out a particular function.

Examples: Circulatory, digestive, excretory, respiratory, reproductive, etc…

Organisms.What are they made up of? They are made up of a number of systems working together that carry out a particular function.

Examples: Animals, plants, fungi, bacteria, algae, etc…
