Case Study Questions on Life Processes in Plants

Case Study Question 1

Passage: The Greenhouse and the Glass Bottle

Students created a miniature garden in a closed glass bottle by planting moss and small plants inside. The teacher explained that plants perform photosynthesis and respiration, maintaining a self-sustaining system. Light enters the bottle, enabling the plants to prepare food using carbon dioxide, water, and sunlight. Oxygen and water vapour released during the process support life inside the bottle.

Q1. What process allows plants to prepare their own food in the presence of sunlight?
(a) Respiration
(b) Germination
(c) Photosynthesis
(d) Transpiration

Answer: (c)
Difficulty Level: Easy
Explanation: Photosynthesis is the process through which plants prepare food using sunlight, CO₂, and water.

Q2. Which gas is taken in by plants during photosynthesis?
(a) Oxygen
(b) Nitrogen
(c) Hydrogen
(d) Carbon dioxide

Answer: (d)
Difficulty Level: Easy
Explanation: Plants absorb carbon dioxide from the air for photosynthesis.

Q3. What is the role of stomata in this process?
(a) Absorb nutrients from the soil
(b) Transport food
(c) Allow gases to enter and exit the leaf
(d) Prevent water loss

Answer: (c)
Difficulty Level: Moderate
Explanation: Stomata are tiny pores in leaves that help in gas exchange – CO₂ in and O₂ out.

Q4. Which of the following is a correct word equation for photosynthesis?
(a) Water + Sunlight → Carbon dioxide + Sugar
(b) Carbon dioxide + Water + Sunlight → Glucose + Oxygen
(c) Oxygen + Glucose → Energy + Water
(d) Carbon dioxide + Oxygen → Glucose + Water

Answer: (b)
Difficulty Level: Tough
Explanation: This is the correct word equation: CO₂ + H₂O + sunlight → Glucose + O₂.

Case Study Question 2

Passage: Why Plants Need Transport Systems

A science experiment was conducted using a balsam plant and coloured water. Over time, students observed the colour rising through the stem and reaching the leaves. The teacher explained this showed transport of water via xylem vessels. Similarly, the phloem transports food from leaves to other parts. These systems are part of a plant’s vascular tissue.

Q1. What is the function of xylem in plants?
(a) Transport of food
(b) Transport of water
(c) Photosynthesis
(d) Exchange of gases

Answer: (b)
Difficulty Level: Easy
Explanation: Xylem transports water and minerals from roots to leaves.

Q2. What does the phloem transport in plants?
(a) Water and minerals
(b) Only oxygen
(c) Food prepared by leaves
(d) Nutrients from soil

Answer: (c)
Difficulty Level: Easy
Explanation: Phloem carries the food made in leaves to all parts of the plant.

Q3. In which part of the plant does photosynthesis mainly occur?
(a) Roots
(b) Stems
(c) Flowers
(d) Leaves

Answer: (d)
Difficulty Level: Moderate
Explanation: Leaves contain chlorophyll and are the main site of photosynthesis.

Q4. Which vascular tissues are responsible for transport in plants?
(a) Epidermis and guard cells
(b) Root hairs and stem
(c) Xylem and phloem
(d) Chloroplasts and mitochondria

Answer: (c)
Difficulty Level: Moderate
Explanation: Xylem and phloem are the two vascular tissues that transport water and food respectively.
