Synthesis of complex organic substances from simple inorganic raw materials in the presence of sunlight and chlorophyll is called as ___ which is a ___ process.

Options

A. photosynthesis, anabolic
B. photosynthesis, catabolic
C. respiration, anabolic
D. respiration, catabolic

Explanation

**Step-by-Step Solution:**

1. **Identify the Process**: The question describes a process where complex organic substances are synthesized from simple inorganic raw materials. This is a key characteristic of photosynthesis.

2. **Components of Photosynthesis**: Photosynthesis occurs in the presence of sunlight and chlorophyll. Chlorophyll is the green pigment found in plants that captures sunlight, which is essential for the process.

3. **Raw Materials**: The raw materials used in photosynthesis are carbon dioxide (CO2) and water (H2O). These are simple inorganic substances.

4. **End Products**: The process results in the formation of glucose (a complex organic substance), along with oxygen (O2) as a byproduct.

5. **Type of Process**: Photosynthesis is classified as an anabolic process. Anabolic processes are those that build complex molecules from simpler ones, which is exactly what happens during photosynthesis.

6. **Final Answer**: Therefore, the synthesis of complex organic substances from simple inorganic raw materials in the presence of sunlight and chlorophyll is called **photosynthesis**, which is an **anabolic** process.
