Gram positive bacteria have cell walls composed of thick layers of peptidoglycan.
Answer:
<em>First</em>, photosynthesis converts carbon dioxide and water into oxygen and glucose.
<em>Then</em>, glucose is used as food by the plant and oxygen is a by-product.
<em>Next</em>, Cellular respiration converts oxygen and glucose into water and carbon dioxide.
<em>Last</em>, water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
hope dis helps ^-^
Oxygen is made and so is glucose (its actually sugar, but glucose is better sounding) by combining carbon dioxide and water using light energy as a source of energy. Also like to make sugars.
