Xylem and Phloem - Part 3 - Translocation - Transport in Plants

The video explains how water and minerals move up the plant through the xylem, driven by transpiration. It contrasts this with the phloem, where sugars and amino acids are actively transported in multiple directions. The phloem uses active transport to move sucrose from sources to sinks, with companion cells providing energy. The video concludes with a summary of these transport processes.

What is the primary function of the xylem in plants?

• Transporting oxygen

• Transporting sugars

• Transporting water and minerals

• Transporting amino acids

How does the phloem transport nutrients like sucrose?

• By passive diffusion

• By active transport

• By gravitational pull

• By osmosis

What are the areas called where sucrose is produced in plants?

• Nodes

• Leaves

• Sources

• Sinks

Which cells provide energy for active transport in the phloem?

• Companion cells

• Root hair cells

• Guard cells

• Sieve tube elements

What is the direction of water movement in the xylem?

• From stems to roots

• In all directions

• From roots to leaves

• From leaves to roots
