Murphy • Water is essential for life, and all organisms depend on it. Copyright © 2010 Ryan P. Murphy • Homework Question: Describe some of the adaptations displayed by plants and animals to survive with low water availability. – Work on bundled homework instead of your journal as we cover them. Copyright © 2010 Ryan P. Murphy • Water requirements and plants. –––- Copyright © 2010 Ryan P. Murphy • Hydrophytes: Plants which grow in water. Copyright © 2010 Ryan P. Murphy • Mesophytes: Plants with average water needs. Copyright © 2010 Ryan P. Murphy • Xerophytes: Plants which grow in dry environments. Copyright © 2010 Ryan P. Murphy • Adaptations of plants to survive with minimal water include. –––- • Using stomata: Structures that can close to keep water in when dry. Copyright © 2010 Ryan P. Murphy • Thick waxy cuticles to keep water in (succulents, cacti) Copyright © 2010 Ryan P. Murphy Copyright © 2010 Ryan P. Murphy • Small leaves, or absence of leaves. Copyright © 2010 Ryan P. Murphy • Water storage tissues. • Which makes more sense to plant in a dry climate? Native deep rooted grasses or non-native grasses? Copyright © 2010 Ryan P. Murphy • Answer! Deep rooted native grasses do not require constant watering to survive and should be planted in areas with water shortages. Copyright © 2010 Ryan P. Murphy • Deep roots • Deep roots • There is a growing movement to plant native species as a front lawn instead of grass. Lots of advantages to the ecosystem. – Are there any disadvantages?

Creating your own study about Isopods. – We will be collecting data periodically over the next week. Copyright © 2010 Ryan P. Murphy • Isopod Research Sheet • Isopod Research Sheet • Information / Research Available Sheet. • Information / Research Available Sheet. • Some general questions. – How are isopods connected to abiotic factors. • Moisture, temperature, light, soil, etc. – What is an isopod? – Where do isopods live? – What do they eat? – What is their reproductive cycle? – What is their importance (niche) and how do they impact people? Copyright © 2010 Ryan P. Murphy • Gathering background information on Terrestrial Isopods. – Use the science name for the internet search. – Find general knowledge first, then focus. – Make focus on the pill bug and abiotic factors – Find a source that is at your ability. – Record the website address, title, author, year.
