Question

1. the reactants for the chemical reaction known as photosynthesis enter the chloroplast. what are these reactants? 2. after photosynthesis is complete, its products can leave the chloroplast. what are these products? 3. write the balanced chemical equation for photosynthesis. 4. what is the energy source that allows photosynthesis to occur?

Explanation:

Step1: Recall photosynthesis reactants

Carbon - dioxide ($CO_2$) and water ($H_2O$) enter the chloroplast as reactants.

Step2: Identify photosynthesis products

Glucose ($C_6H_{12}O_6$) and oxygen ($O_2$) are the products that can leave the chloroplast.

Step3: Write balanced chemical equation

The balanced chemical equation for photosynthesis is $6CO_2 + 6H_2O\xrightarrow{light}C_6H_{12}O_6+6O_2$.

Step4: Determine energy source

Light (sunlight) is the energy source for photosynthesis.

Answer:

1. Carbon - dioxide and water.
2. Glucose and oxygen.
3. $6CO_2 + 6H_2O\xrightarrow{light}C_6H_{12}O_6+6O_2$
4. Sunlight.
