Question 1

What is the plant transport system and why is it important in the Singapore Curriculum Science syllabus?

Accepted Answer

The plant transport system refers to the network of tissues responsible for moving water, nutrients, and sugars throughout a plant. It is crucial for maintaining plant health and supporting growth. In the Singapore Curriculum Science syllabus, understanding this system helps students appreciate how plants sustain themselves and contribute to ecosystems.

Question 2

How do xylem and phloem function in the plant transport system?

Accepted Answer

In the plant transport system, xylem and phloem are two types of vascular tissues. Xylem transports water and dissolved minerals from the roots to the rest of the plant, while phloem distributes sugars and other organic nutrients produced during photosynthesis from the leaves to other parts of the plant. This dual system ensures that all plant cells receive the necessary resources to function.

Question 3

What role do roots play in the plant transport system?

Accepted Answer

Roots are essential in the plant transport system as they absorb water and minerals from the soil. These resources are then transported through the xylem to the rest of the plant. Additionally, roots anchor the plant in the soil, providing stability and support for growth.

Question 4

How does the process of transpiration contribute to the plant transport system?

Accepted Answer

Transpiration is the process by which water evaporates from the leaves, creating a negative pressure that pulls water up through the xylem from the roots. This movement not only helps in transporting water and nutrients but also aids in cooling the plant and maintaining its structural integrity.

Question 5

Why is understanding the plant transport system important for students studying Science in Singapore?

Accepted Answer

Understanding the plant transport system is vital for students as it provides insights into how plants grow and survive, which is fundamental to ecosystems and agriculture. This knowledge is part of the Singapore Curriculum Science syllabus, helping students develop a comprehensive understanding of biological systems and their importance to life on Earth.
