Chlorophyll and Photosynthesis Concepts

Green plants, known as autotrophs, can produce their own food using simple inorganic substances like carbon dioxide, water, and minerals. They are unique in their ability to capture energy from the Sun, a process facilitated by the green pigment chlorophyll found in chloroplasts within their leaves. This energy conversion process, known as photosynthesis, transforms solar energy into chemical energy stored as carbohydrates.

Why are green plants referred to as autotrophs?

• They rely on other organisms for food.

• They can produce their own food using sunlight.

• They do not require any nutrients.

• They consume only inorganic substances.

Which of the following is NOT an inorganic substance used by plants in food production?

• Glucose

• Carbon dioxide

• Potassium

• Water

What is the primary role of chlorophyll in leaves?

• To absorb water

• To trap solar energy

• To store nutrients

• To protect the plant from pests

Where is chlorophyll located within the plant cell?

• Mitochondria

• Nucleus

• Chloroplast

• Cell wall

What is the end product of the photosynthesis process?

• Vitamins

• Lipids

• Carbohydrates

• Proteins
