SITTING IN ASSIGNED SEATS WORKING ON SOMETHING QUIETLY GETTING OUT YOUR SUPPLIES…PENCIL AND NOTEBOOK

 Look at the 3 images below….explain in your own words what you think is happening in each picture

 Understand what TROPISM is.  Understand the 4 ways that plants change the way they grow based on their environment.

 Add entry to Table of Contents  6.L.2.2 Plant Adaptations  Assign the next number

 Label Next Available Page:  6.L2.2 Plant Adaptations  Number page to match Table of Contents entry  Circle the number

 Tropism: process of plants changing due to a stimulus (changes in their environment)  Plants can change  Their growth  When they reproduce  The position of their roots, stems and leaves

 Environmental changes (stimuli) that effect plants:  Gravity  Sunlight  Touch  Moisture (water)

 Phototropism: the way a plant grows or bends because of sunlight

 Draw a picture of what a plant would look like if it ONLY had light coming on to it from the RIGHT side.

 Tropism Animation  Glossary Term - Tropism Glossary Term - Tropism  tt=tropism tt=tropism

 vW8k vW8k  ks1Y ks1Y

 Geotropism: the way a plant grows or bends because of gravity  Plant structures can sense up and down  Stems of plants grow upright  Roots of plants grow down

 V_L0 V_L0

 Thigmotropism: the way a plant grows or bends because of touch (stimulus).

 Clematis are known for twining vines that revolve as they grow, making a full circle until they find an object to climb; this searching process is known as thigmotropism.

 xA xA  mA8 mA8

 Hydrotropism: the way a plant grows due to the presence of water (stimulus).  When roots sense water, they bend and grows towards it.

 es/image008.gif es/image008.gif

 Stimulus (changes) can be positive or negative.  Positive = toward stimulus  Negative = away from stimulus

 Plant moving toward stimulus (the sun).

 Negative = roots growing away from sun.  The roots are growing AWAY from the sun because they need water for survival.

 Draw the tree with roots on your paper and label the positive and negative.

 bzHE bzHE  Mr. Parr

 Draw a picture showing the 4 ways plants are affected in how they grow.

 Teams of 2 or 3 with the students around you.  We will read an article about tropism together.  Pencils are DOWN while reading the article.  Then you will answer question 1 with your partner.  As SOON as you know the answer and you have BOTH written it on your paper. You can run up and ring the bell.  Points: First team: 3 points Second team: 2 points Third team: 1 point
