WORKSHEET

Topic: Photosynthesis

1. Define photosynthesis in your own words. (Hint: Green plants make food using Sunlight.)
2. Write the word equation for photosynthesis. Carbon dioxide + ________________ → _______________ + Oxygen
3. State one importance of photosynthesis for plants and animals.
4. List the essential conditions required for photosynthesis. Draw a quick sketch showing Where each comes from.
5. Fill in the blanks:  Glucose is broken down during ____________________ to provide energy for The plant’s growth.  since glucose is soluble and would affect the plant's water balance, it is

Photosynthesis is the process by which green plants use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen as a by- product.

1. The Word Equation Carbon dioxide + Water → Glucose + Oxygen
2. Importance of Photosynthesis For Plants: It allows them to create the energy (food) they need to grow, reproduce, and survive. For Animals: It provides the oxygen we need to breathe and serves as the primary source of food (either directly by eating plants or indirectly by eating animals that eat plants).
3. Essential Conditions

The four essential conditions are: Chlorophyll: The green pigment in leaves that traps light. Sunlight: The energy source for the reaction. Carbon Dioxide: Taken in from the air. Water: Absorbed by the roots from the soil.

1. Fill in the Blanks Glucose is broken down during respiration to provide energy for the plant’s growth. Since glucose is soluble and would affect the plant's water balance, it is converted into insoluble starch and stored in roots or tubers.

for energy, or stored for later use to help the plant grow and stay healthy.

1. Water Shortage and Glucose Production If a plant doesn't get enough water, glucose production will decrease or stop. Water is a raw material for the chemical reaction; without it, the plant cannot complete the process. Additionally, plants often close their stomata (pores) to save water, which also blocks carbon dioxide from entering, further stopping photosynthesisroduction?
