FROM CELL TO SYSTEMS

Animals and plants are made of cells. Tissues are made from cells of a similar type. Organs are made from tissues, and systems are made from several organs working together. They all make up an organism.


cells - tissues - organs - organ systems - organism

CELLS - AN INTRODUCTION

Cells
Cells are very small. They are the basic building blocks of all animals and plants. 


Animal cells usually have an irregular shape, and plant cells usually have a regular shape
Cells are made up of different parts. It is easier to explain what these parts are by using diagrams like the ones below.
Animal and plant cells both have a cell membrane, cytoplasm, and a nucleus. Plant cells also have chloroplasts, a vacuole and a cell wall.

Animal cells and plant cells both contain:
  • cell membrane, cytoplasm, nucleus
Plant cells also contain these parts, not found in animal cells:
  • chloroplasts, vacuole, cell wall
The table summarises the functions of these parts.
PartFunctionFound in
Cell membraneControls what substances can get into and out of the cell.Plant and animal cells
CytoplasmJelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm.Plant and animal cells
Nucleus
Controls what happens inside the cell. Carries genetic information.
In exams don't call the nucleus the 'brain' of the cell. That is not a good description and will not get you marks.
Plant and animal cells
ChloroplastWhere photosynthesis happens – chloroplasts contain a green substance called chlorophyll.Plant cells only
VacuoleContains a liquid called cell sap, which keeps the cell firm.Plant cells only
Cell wallMade of a tough substance called cellulose, which supports the cell.Plant cells only

Have you ever wondered how crude oil, natural gas and coal were formed? 
Did you know they are also called Fossil Fuels?

Watch the next videos to learn more!

- Crude oil and gas formation

- Coal

- Fossil Fuel formation




RENEWABLE ENERGY SOURCES


Renewable energy sources can be used again and again.

From all these sources, it is important to remember that biomass and wood are only renewable if the trees and crops are replanted.


- Solar energy
- Wind energy
- Water - Hydroelectric power
- Biomass
- Geothermal energy 

Watch this video if you want to know more about the 10 Future Energy Sources.

And... if you have time you can watch Bill Nye the Science Guy full episode about energy!

ENERGY SOURCES

There are different energy sources that can be divided into two groups: renewable and non-renewable

In this video you will learn about sources of energy, the difference between renewable and non-renewable energy sources and ways to conserve energy right at home! 

ENERGY

Energy is the ability to do work. Any change needs energy.
Here you have some of the videos we've watched during lessons. I hope you enjoy them!


There are different forms of energy. You can revise them watching Tim&Moby's video.
