AS Biology - Transport systems in plants (OCR A Chapter 9.1)

Показать описание

The plants we normally talk about and refer to are dicotyledonous plants - multicellular plants that make seeds containing two cotyledons (organs that are food stores). They have the vascular bundle - xylem and phloem - to transport substances around the plant. Here we go through the basic functions and structures of these two vessels.

Thank you so much for uploading these videos, they're saving me so much time from having to use dull textbooks and, me being a visual learner, makes these twice as useful <3

Hi, thanks for another excellent video like your one on photophosphorylation!
You mention at the end that you will discuss the companion cell function in another video, where can I find this or is that being created another time?
Thank you
