The assignment is asking for a detailed drawing of a leaf with labels for the starting materials (light energy, oxygen, sugar, water, carbon dioxide) and products, along with arrows to show how these substances enter, leave, or remain in the plant. Additionally, you need to label and define the terms photosynthesis, glucose, chlorophyll, chloroplasts, and stomata.

Photosynthesis: the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Glucose: a simple sugar that is an important source of energy for living organisms.

Chlorophyll: a green pigment found in the chloroplasts of plants that is responsible for capturing light energy for photosynthesis.

Chloroplasts: the organelles in plant cells in which photosynthesis takes place.

Stomata: small pores on the surface of plant leaves that allow for gas exchange, including the intake of carbon dioxide and the release of oxygen.

Steps of photosynthesis:
1. Light absorption: chlorophyll in chloroplasts absorbs sunlight.
2. Water absorption: roots absorb water from the soil and transport it to the leaves.
3. Carbon dioxide absorption: stomata take in carbon dioxide from the surrounding air.
4. The light-dependent reactions: light energy is used to split water molecules, releasing oxygen and producing ATP and NADPH.
5. The Calvin cycle (dark reactions): ATP and NADPH from the light-dependent reactions are used to convert carbon dioxide into glucose.
6. Release of oxygen: oxygen is released as a byproduct of photosynthesis.

Balanced chemical equation of photosynthesis:
6CO2 + 6H2O + light energy -> C6H12O6 + 6O2

Products and reactants of the photosynthesis equation:
- Reactants: carbon dioxide, water, and light energy
- Products: glucose and oxygen
