2 What is up coming in Biology Tuesday, May 1 st Tutorials This is the LAST DAY you can retake Quiz #20. This is also a good time to retake exit tickets. Thursday, May 3 rd Biology EOC Summit Will be mandatory for some. I will have a list of students will a pass for who will be able to come. If you do not get invited, come on May 8 th for one on one review. Tuesday, May 8 th Last chance to review and study Will be mandatory for some Mandatory afterschool meetings will be a detention is not attended. Wednesday, May 9 th Biology STAAR/EOC

6 Primary Life coming to area with no soil, a newly formed ecosystem Secondary Life returning to an ecosystem after a disturbance

7 Primary Volcanic eruptions (new lava makes new land/island) Glaciers (scrape an area raw, leaving only rock exposed) Severe landslide or flood that removes all soil Secondary Forest fires Hurricanes Tornadoes Deforestation

8 Primary Secondary Takes a long time ( years) Relatively fast ( years)

9 Climax community a stable group of plants and animals that is the end of a succession process.

10 Pioneer Species The first living things to arrive after a large ecological disturbance or when new land forms Lichen: an organism consisting of a fungus and algae living together Take 15 sec to write the word lichen next to Pioneer Species

12 Billions of bacteria live in the human digestive system. These bacteria are referred to as microflora, or gut flora. These bacteria break down food remains that have not been digested earlier in the digestive system. They stop harmful bacteria and fungus from invading the body. Some of these are beneficial and others are potentially harmful. Microflora - #4

13 Beneficial bacteria that can be found the human digestive system. The human digestive system contains millions of beneficial bacteria to help our body break down food. Probiotics can also provide antibiotic resistance against bacteria. Most commercially-promoted fermented milk products contains beneficial types of bacteria. Natural yogurt and Yakult, a milk product, are examples of foods which contain probiotics.

14 BIOTECHNOLOGY - #3 The industrial application of living organisms is called biotechnology. One example of a way that humans use microorganisms is to develop medicines like antibiotics (Anti = against and bio = life) These medicines attack bacteria and other unicellular organisms that are pathogenic (disease causing) for humans.

15 Nitrogen Cycle Nitrogen Fixing bacteria is used to take Nitrogen from the air and put it in the soil so it can be used. The only useable form for plants is nitrates. Decomposers keep the nutrients moving through the cycle.

16 Phototropism Phototropism is growth or movement of a plant that responds to a light stimulus A hormone called auxin that cause the plant to grow on one side.

17 Geotropism Geotropism-growth or movement of a plant in response to gravity. Roots grow in the direction of gravity Stems grow opposite the direction of gravity

18 Hydrotropism Hydrotropism the growth or movement of a plant in response to water.

19 Thigmotropism is growth or movement of a plant in response to touch. The Venus flytrap, or Dionaea muscipula is a plant that exhibits this characteristic. Thigmotropism

20 Independent Practice Answer questions all question starting at Independent Practice Work must be done silently and independently. No Talking. If you have a question or request raise a silent hand and be patient. For independent practice, today we will be working silently and independently for 6 minutes.

21 Group Practice Review the questions answered during Independent practice. Go over each question. Each table member should explain why they selected their answer. Work must be done at a level ONE volume, which means I should not be able to hear you from my desk. Remain in your seat and only talk to people at your table. Make sure to keep conversations on topic. If you have a question or request raise a silent hand and be patient. For group practice, today we will be working for 10 minutes.
