Warm-up: Hand in graphing activity to Ms. Nagle. Then, in your science journal  Today’s Goal:  I can explain how plants respond to the environment Turn to page 118. Silently read page 118 and 119 Plant Tropism- Light and Gravity. Stop at Seasonal Responses. Define Tropism.

What do you notice about all of the sunflowers in this field?

Growth in response to a stimulus Growth in response to a stimulus Stimuli that effect plant growth: Stimuli that effect plant growth: Light (phototropism) Light (phototropism) Gravity (gravitropism) Gravity (gravitropism) Water (hydrotropism) Water (hydrotropism) Positive tropism  grows towards stimulus Positive tropism  grows towards stimulus Negative tropism  grows away from stimulus Negative tropism  grows away from stimulus Often, we don’t think of plants as being real organisms because they don’t think or move around. While they may not move consciously (or very quickly) plants do respond to changes in the environment.

Remember, this all occurs at the cellular level! No brain required!

Have you ever seen a tree growing out of embankment like this? Why does this happen? Why does this happen?

Remember, this all occurs at the cellular level! No brain required! Organisms response to contact

What do you think is meant by “limiting factor”? What are the different things that plants need in order to survive…without which their growth would be limited? What gas could be considered a limiting factor for humans but NOT for plants?

Warm-up: Turn to reviews in your packet. Then, in your science journal  Today’s Goal:  I can explain how plants respond to the environment Explain the difference between vascular seed plants and vascular seedless plants. Homework: Botany Test TOMORROW STUDY! Botany Test TOMORROW STUDY!
