What is the cell? The cell is a

The Stanley Miller experiment was created to investigate how large and compounds were formed. It consisted of a containing inorganic gases such as methane, ammonia and CO2 to represent a earth atmosphere. He then added and heat.
The gases came to form more complex organic molecules.

We then need a of molecules through the membrane via protein gates for sugars, amino acids ions and others.

A cell must be able to and divide, is the cellular blueprint. It undergoes replication, transcription and translation.
Overall cells are a mix of macromolecules and small molecules surrounded by a membrane. The building plan is contained on DNA and multiplication is achieved by .

CO2 (carbon dioxide) and N2 (atmospheric nitrogen) must be converted into form by and nitrogen . fix nitrogen in their root .

• Nucleic acids: storage and transfer
• Proteins: enzymes and proteins, , regulators
• Lipids: building blocks for , , signalling
• Carbohydrates: Structural role, energy , signalling
• Different energy sources: , organic and inorganic molecules
• Importance of CO2 and N2 fixation
