TRANSPORTATION IN PLANT XYLEM AND PHLOEM_UNSOLVED PAPER
Topic: Transportation in Plants Xylem and Phloem
Q1. Which tissue is mainly responsible for transporting water and minerals in plants?
- Phloem
- Xylem
- Epidermis
- Cambium
Q2. Food prepared during photosynthesis is transported through:
- Xylem
- Phloem
- Cortex
- Root hairs
Q3. The upward movement of water in plants is mainly caused by:
- Respiration
- Transpiration pull
- Photosynthesis
- Pollination
Q4. Which part of the plant absorbs water and minerals from the soil?
- Stem
- Leaves
- Root hairs
- Flowers
Q5. A gardener waters a potted plant regularly. Which tissue carries the absorbed water from the roots to the leaves?
- Phloem
- Xylem
- Meristem
- Epidermis
Q6. Phloem transports food:
- Only upward
- Only downward
- In both upward and downward directions
- Only from roots to leaves
Short questions
Q1. State any two differences between xylem and phloem.
Q2. Explain the role of root hairs in the transportation of water in plants.
Q3. What is transpiration pull? How does it help in the movement of water?
Q4. A student notices that a plant kept without water for several days begins to wilt. Explain this observation in terms of water transportation.
Q5. Why is phloem transport called translocation?
Q6. Describe the role of leaves in the transportation of water through transpiration.
Q1. Explain the complete pathway of water and mineral transport from the soil to different parts of a plant. Mention the role of root hairs, xylem, and transpiration.
Q2. Compare xylem and phloem with respect to:
Material transported
Direction of transport
Type of cells
Main function
Importance in plant life
Present your answer in a suitable table.
Q3. During the summer season, a farmer waters crops early in the morning instead of the afternoon. Explain how this practice supports efficient transportation of water in plants.
Q1. Read the following case:
A science teacher places a freshly cut white flower in coloured water. After a few hours, the petals show the colour of the dye.
Based on your understanding of transportation in plants:
Identify the tissue responsible for this observation.
Explain how the coloured water reaches the petals.
Describe the role of transpiration in this activity.
Q2. A biology student prepared the following flow chart:
Soil → Root Hairs → Roots → Stem → Leaves
Explain how water and minerals move through each stage of the flow chart. Mention the role of the transport tissues involved.
Q3. Read the following observations:
Leaves prepare food by photosynthesis.
Roots absorb water and minerals.
Food reaches growing fruits and roots.
Water reaches leaves continuously.
Using these observations, explain how xylem and phloem work together to transport essential materials throughout the plant.
