PPT-Plant Tropisms Warm-up:

Hand in graphing activity to Ms Nagle Then in your science journal Todays 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.

Paleoclimatology - The study of past climate, from times prior to instrumental weather measurements. . Warm up (11-23-15). Explain what you know about plants.. Try to be specific and use scientific terms if possible.. Outline. Objectives. Plant Background Info. Objectives. To gain background information about plants and how they colonized land. 1)What are the two major categories of cells?. 2) What is the main difference between prokaryotes and eukaryotes.. 3) Give two examples of eukaryotes. 4) True/False viruses are a type of cell. 5) How does a virus reproduce?. The rock pocket mouse fur coat exists in two morphs or variations, light and dark. Even though natural selection has taken place to produce these different variations, the underbelly of the pocket mouse has remained a light color in both varieties. How would you explain why the underbelly on pocket mouse with dark fur remains a light color?. How Plants Respond to External . Stimuli. Essential Standards. 6.L.. 2 Understand . the flow of . energy through . ecosystems and the responses of populations to . the biotic . and . abiotic. factors in their environment.. Plant Hormones. Hormones are chemical signals that coordinate the various parts of an organism. A hormone is a compound produced in one part of the body which is then transported to other parts of the body, where it triggers responses in target cells and tissues. Coy Clausen. Rules . No stupid questions. I don’t know all the answers. Experience is a great teacher. There are lots of ways to be successful. Choose a garden site. Need 6-8 hours of sun. Need a water source – easer access the better. The zero line is the 10-year average of global . average temperature for the years 1995–2004, . centered on January 1, 2000.. Paleoclimatology - The study of past climate, from times prior to instrumental weather measurements. . Phototropism. Geotropism . Thigmotropism. Hydrotropism. Chemotropism. Thermotropism. 3 main types. TROPISM. Plant growth in response to a stimulus . (“tropo” – ”turn”) . *Can be positive or negative. A Tropism is a plant’s directed growth towards or away from a stimulus. . Tropisms. Tropisms. We will cover 4 tropisms.. Gravitropism. Hydrotropism. Phototropism. Thigmotropism. Gravitropism. Gravitropism. TEKS 7.7C. Tropism -. The response of plants to external stimuli. Phototropism. - . The tendency of a plant to grow towards light. Geotropism (Gravitropism). . - . The tendency of a plant to grow in a direction in response to gravity (roots-down).
