Lesson: Translocation in the Phloem Biology

In this lesson, we will learn how to describe the process of translocation in plants.

Lesson Plan

Students will be able to

describe the process of translocation in terms of the movement of sucrose around the plant,
recall that the movement of sucrose is bidirectional,
outline the role of the components of the phloem (sieve tube elements and companion cells) in the transport of sucrose,
describe the structure and the function of companion cells in assisting the movement of sucrose,
describe the structure and the function of sieve tube elements in the phloem,
analyze and discuss experiments performed to understand the transport of sugars in the phloem.

Q1:

Which vessel in the plant is responsible for transporting sugars and amino acids?

Q2:

Which of the following best explains the relationship between light intensity and translocation?

Q3:

When sugars are not being used by the plant, they can be stored as an insoluble compound. What compound are sugars mainly stored as in plants?
