Question

Accepted Answer

### 1. Definition of photosynthesis
# Brief Explanations:
Photosynthesis is the process by which green plants, algae, and some bacteria use sunlight, carbon dioxide, and water to synthesize glucose (food) and release oxygen. The chemical equation is $6CO_2 + 6H_2O \xrightarrow[	ext{Chlorophyll}]{	ext{Light Energy}} C_6H_{12}O_6 + 6O_2$.
# Answer:
Photosynthesis is the process where plants, algae, and some bacteria use light energy, carbon dioxide, and water to produce glucose (chemical energy) and oxygen, occurring in chloroplasts with chlorophyll.

### 2. Three things required for photosynthesis
# Brief Explanations:
From the photosynthesis equation and biological knowledge, the three key requirements are light energy (from the sun), carbon dioxide ($CO_2$, from the air), and water ($H_2O$, from the soil/ environment).
# Answer:
1. Light energy (sunlight)
2. Carbon dioxide ($CO_2$)
3. Water ($H_2O$)

### 3. Two things produced by photosynthesis
# Brief Explanations:
The products of photosynthesis are glucose (a carbohydrate, used for energy/storage) and oxygen ($O_2$, released into the atmosphere). This is confirmed by the chemical reaction of photosynthesis.
# Answer:
1. Glucose ($C_6H_{12}O_6$)
2. Oxygen ($O_2$)

### 4. One of the three things required (hint - required factor)
# Brief Explanations:
The three requirements are light, $CO_2$, and $H_2O$. A common answer here could be “light energy” (or “carbon dioxide” or “water” – all are correct, but light is a key energy source).
# Answer:
Light energy (or Carbon dioxide / Water)

### 5. One of the two things produced (hint - product)
# Brief Explanations:
The two products are glucose and oxygen. A common answer is “oxygen” (or “glucose” – both are correct; oxygen is released, glucose is stored/used).
# Answer:
Oxygen (or Glucose)

### 6. Definition & purpose of stomata
# Brief Explanations:
Stomata are tiny pores (usually on leaf undersides) bordered by guard cells. Their purpose is gas exchange: taking in $CO_2$ for photosynthesis and releasing $O_2$ and water vapor (transpiration). They also regulate water loss.
# Answer:
**Definition**: Stomata are small openings (pores) in plant leaves (and stems) surrounded by guard cells, which open/close to control gas exchange.
**Purpose**: Facilitate gas exchange (absorb $CO_2$ for photosynthesis, release $O_2$ and water vapor) and regulate water loss (transpiration).
