question
_Photosynthesis_ takes place in nearly all life.
answer
cellular respiration
question
List the following: All these are about Photosynthesis: its function, location of reactions, reactants and products.
answer
function: energy capture
location of reactions: chloroplasts
reactants: water + carbon dioxide
Products: glucose + oxygen
question
List the following: all these are about Cellular Respiration: its function, location of reactions, reactants and products.
answer
function: organisms that get energy from food when oxygen is available.
location of reactions: cytoplasm, mitochondria
reactants: oxygen + glucose
products: carbon dioxide, water, energy
question
How does an understanding of the process of cellular respiration support the theory that the cell is the basic functional unit of life:
answer
The understanding that a cell is a basic unit for life is because cellular respiration is when organisms obtain energy from food. The organisms are made of cells, adding to the fact that cells are a basic unit of life.
