To see if substances found now made by living things could be formed in the conditions thought to have existed on early earth
Organic and inorganic what do they mean
Living ,non living
What are cells that don’t require oxygen to live

What is are organelles
The things or mass inside a cell
How does photosynthesis happen and what does it produce
Carbon dioxide+water+light———–>
Glucose+oxygen is made also known as food
What is the order of these happenings
Chemosynthesis, photosynthesis,anaerobic respiration, aerobic resperation
Chemosynthesis,anaerobic respiration, photosynthesis,aerobic resperation
