Conditions Affecting Plant Growth

Conditions Affecting Plant Growth

Learners can:

• predict how changing environmental conditions will affect plant growth and development

• relate the function of stomata to changes in a plant's environment

Vocabulary: nutrient, transpiration

​Meet King Bob. If you don't see King Bob, he is in the bottom right of the screen.

What are some factors that could affect Bob's ability to grow?

​All plants live in a habitat that provides the factors the plant needs to survive. However, sometimes there is not enough or too much of a resource for a plant to grow normally. Some of the resources that can affect plant growth are:

• water

• nutrients

• light

In this lesson, you will learn some of the ways that these resources affect the way plants grow. Continue on to learn about how water affects plants.

​What do we know about the water cycle?

Can it affect a plant's ability to grow?

The diagram below is a model of the water cycle. Circle the set of arrows represents transpiration?

​***Transpiration plays an important role in the water cycle. A study of rainfall patterns in the Amazon River Basin found that when trees were cut down, 69% less rain fell in the area. The transpiration from the trees produced most of the rainfall for tropical rainforests. Transpiration plays a vital role in global climate. ***

WOAH!
