True or False-
During photosynthesis, oxygen is converted to carbon dioxide.
False, Carbon Dioxide is converted to oxygen.
Which component is missing from the process of photosynthesis?
Carbon Dioxide + Water + Sunlight → _________ + Oxygen (2 points)
Glucose
Which description properly describes the plant structures involved in photosynthesis?
Stomata take in carbon dioxide and release oxygen.
A capacity to do work that can produce physical changes within living and nonliving systems
Energy
A type of sugar that is produced during photosynthesis to store chemical energy
Glucose
An organelle that contains chlorophyll and in which photosynthesis takes place
Chloroplast
A green pigment present in all plants that absorbs light to provide energy for photosynthesis
Chlorophyll
What evidence supports the law of conservation of energy?
Chemical energy is converted to light energy during photosynthesis.
Oxygen is made from the breakdown of carbon dioxide during photosynthesis.
Energy is absorbed by chlorophyll during photosynthesis.
Light energy is absorbed by plants and converted to chemical energy.
Light energy is absorbed by plants and converted to chemical energy.
What evidence supports a conservation law?
Energy from sunlight becomes glucose during photosynthesis.
Carbon dioxide becomes glucose and oxygen during photosynthesis.
Hydrogen is made from the breakdown of carbon dioxide during photosynthesis.
Glucose and oxygen become carbon dioxide and water during photosynthesis.
Energy from sunlight becomes glucose during photosynthesis.
Which component is missing from the process of cellular respiration?

Photosynthesis
Which description properly describes a step involved in cellular respiration?
Glucose is created, then the energy gained is transferred to the energy molecule.
Carbon dioxide and water are released after the energy molecule is charged.
Water is divided into carbon dioxide and glucose.
Oxygen is combined with ATP to energize it.
Carbon dioxide and water are released after the energy molecule is charged.
