Article discussing the structure, function, and efficiency of stomata, the apertures on plants' leaves that regulate gas and water vapor exchange during photosynthesis. (Published: August 3, 2010)

Describes stomata and their functions in photosynthesis, transpiration, and regulation of water retention and loss by plants.

Transpiration is an important plant process that releases water into the air through the stomata in leaves. This resource describes the process, the role the stomata play, factors that have an impact on transpiration, and why it is so...

A lesson unit where students work in small groups to examine stomata on a leaf's upper and lower surfaces. They then conduct an experiment to test whether plants can survive without air, learning about transpiration in the process.

This tutorial examines how water moves through a plant. Follow the pathway that water takes through plants from the roots to evaporation from cells in the leaves. Learn what controls rates of transpiration, how environmental conditions...

A comprehensive delve into the many facets of photosynthesis. Text is supplemented with effective pictures and graphs. Review questions can be found at the end of the site.

This is a good explanation of plant water balance issues and carbon fixing cycles. Transpiration processes are explained well with links to additional information.

Discusses major aspects of leaf structure and function. Contains examples of modifications of leaf structure and function.

Learn how plants absorb water through either root systems or vessels in their stems with this site. Also understand how important water is to the make up of the plant!

Use site from Suzy's world, which is a personal site from Suzy Cato, in order to learn how plants and trees "eat." Content includes fun facts and great experiment.

Provides a simple definition and description of photosynthesis in plants and explains why photosynthesis is so vital for all living organisms.

This resource describes three different types of photosynthesis that take place in plants and the plant characteristics and environmental conditions that determine which type takes place.
