💡 Key Idea
Plants run life processes silently.
Plants are living organisms that carry out essential life processes to survive, grow, and reproduce. Unlike animals, they make their own food through photosynthesis and perform respiration, transport, and excretion to maintain life.
↳ Plants perform all life processes, just like animals, but make their own food.
📖 Definition
Sunlight becomes food.
Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to make glucose (food) and release oxygen. It occurs in the chloroplasts of leaf cells, which contain the green pigment chlorophyll.
↳ Photosynthesis converts light energy into chemical energy stored as food.
⭐ Important Fact
Green pigment captures sunlight.
Chlorophyll is the green pigment in chloroplasts that absorbs sunlight (mainly red and blue wavelengths) and converts it into chemical energy. Without chlorophyll, photosynthesis cannot occur.
↳ Chlorophyll is the molecule that captures light energy for photosynthesis.
⚙️ Process
Light to sugar in steps.
↳ Photosynthesis has two main stages: light-dependent and light-independent reactions.
📖 Definition
Plants breathe too.
Respiration in plants is the process of breaking down glucose to release energy for life activities. It occurs in mitochondria and happens 24 hours a day, unlike photosynthesis which only occurs in light.
↳ Respiration releases energy from food and occurs day and night.
⚖️ Comparison
Opposite but linked processes.
↳ Photosynthesis stores energy; respiration releases it.
⚙️ Process
Water and food travel.
Plants have a transport system made of xylem and phloem tissues. Xylem carries water and minerals from roots to leaves. Phloem carries food (glucose) from leaves to other parts of the plant.
↳ Xylem transports water; phloem transports food.
⭐ Important Fact
Leaves lose water vapor.
Transpiration is the loss of water vapor from leaves through stomata. It helps in cooling the plant and pulling water upward through xylem. Stomata are tiny pores mainly on the underside of leaves.
↳ Transpiration drives water movement and cools the plant.
📖 Definition
Plants remove waste too.
Plants produce waste products like oxygen (from photosynthesis) and carbon dioxide (from respiration). Other wastes are stored in vacuoles, leaves, or bark and removed when leaves fall or bark sheds.
↳ Plants excrete waste through gases, storage, and shedding.
✏️ Example
Pores control gas exchange.
Stomata are tiny openings on leaf surfaces that allow gas exchange (CO₂ in, O₂ out) and transpiration. They are controlled by guard cells that open and close the pore based on water and light conditions.
↳ Stomata are regulated pores for gas exchange and water loss.
⚠️ Common Mistake
Don't confuse day and night.
↳ Respiration is continuous; photosynthesis needs light.
🎯 Exam Tip
Balance the photosynthesis equation.
In exams, you may be asked to write the balanced equation for photosynthesis. Remember: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ in the presence of light and chlorophyll.
↳ Memorize the balanced photosynthesis equation.
Life processes in plants include nutrition (photosynthesis), respiration, transport, excretion, and reproduction. Plants make their own food using sunlight, water, and carbon dioxide, and they transport water and nutrien…

All 17 questions, laddered from warm-up to topper-level, each with its answer and the reasoning behind it.
Q1. Which process do green plants use to make their own food?
BeginnerA · Photosynthesis
Photosynthesis is the process by which green plants use sunlight, water, and carbon dioxide to make food.
Q2. Which gas do plants take in from the air during photosynthesis?
BeginnerD · Carbon dioxide
Plants absorb carbon dioxide from the air for photosynthesis.
Q3. Which part of the plant mainly absorbs water and minerals from the soil?
BeginnerB · Roots
Roots anchor the plant and absorb water and minerals from the soil.
Q4. Which of these is required for photosynthesis to occur?
BeginnerB · Sunlight
Sunlight provides the energy needed for photosynthesis.
Q5. Photosynthesis occurs only in the presence of sunlight.
BeginnerA · True
Sunlight is essential for photosynthesis; it provides energy to split water and fix carbon dioxide.
Q6. Plants take in oxygen only at night.
BeginnerB · False
Plants respire all the time, taking in oxygen and releasing carbon dioxide, both day and night.
Q7. What is the green pigment in leaves that captures sunlight called?
IntermediateD · Chlorophyll
Chlorophyll is the green pigment that absorbs light energy for photosynthesis.
Q8. Which of the following is a product of photosynthesis?
IntermediateD · Oxygen
Oxygen is released as a by-product during photosynthesis.
Q9. The process by which plants lose water vapour through small openings in leaves is called:
IntermediateD · Transpiration
Transpiration is the loss of water vapour from plant leaves through stomata.
Q10. Which tiny openings on the surface of leaves allow gas exchange?
IntermediateB · Stomata
Stomata are small pores on leaves that allow carbon dioxide to enter and oxygen to exit.
Q11. Which tissue transports water and minerals from roots to other parts of the plant?
IntermediateD · Xylem
Xylem is the vascular tissue that conducts water and dissolved minerals upward from roots.
Q12. Which tissue transports food prepared in leaves to other parts of the plant?
IntermediateC · Phloem
Phloem transports the food (sugars) made in leaves to storage organs and growing parts.
Q13. Plants respire:
IntermediateA · All the time
Respiration in plants occurs continuously, day and night, to release energy from food.
Q14. Which of the following is NOT a life process in plants?
IntermediateC · Locomotion
Plants do not move from place to place (locomotion); they are fixed. Photosynthesis, respiration, and transpiration are life processes.
Q15. The food made by plants during photosynthesis is stored mainly as:
IntermediateA · Starch
Plants convert glucose into starch for storage.
Q16. The movement of water through a plant from roots to leaves is mainly due to:
AdvancedB · Transpiration pull
Transpiration pull, created by water loss from leaves, helps draw water upward through the xylem.
Q17. Which of the following best describes the role of stomata in plants?
AdvancedD · They regulate gas exchange and water loss
Stomata open and close to control the exchange of gases and the loss of water vapour.
