The video tutorial explains how nutrients like sugars and proteins are transported from the cells where they are produced to other parts of the plant that require them. It describes the structure and function of the phloem, highlighting the different types of cells it contains, including those with sieve-like structures that facilitate the movement of molecules. The tutorial also covers the concept of bidirectional nutrient flow, allowing nutrients to move both up and down the plant.

What is the primary role of nutrients like sugars and proteins in plants?

• To provide energy for photosynthesis

• To transport water throughout the plant

• To support growth and development in various parts of the plant

• To protect the plant from pests

Which of the following best describes the arrangement of cells in the phloem?

• Randomly scattered

• Forming columns

• Arranged in a single layer

• Clustered in groups

What is the function of the sieve-like structures in phloem cells?

• To block harmful substances

• To allow molecules to pass between cells

• To support the plant structure

• To store nutrients

In which direction do nutrients move through the phloem?

• Only upwards

• Only downwards

• In both directions

• In a circular motion

What type of cells are primarily involved in the transport of nutrients in plants?

• Leaf cells

• Phloem cells

• Root cells

• Xylem cells
