Grab a Life: Plants video questions sheet off of the front table. Get out your homework or get it out of the basket and be ready to grade. SPI 0807.5.2 Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment. How have plants survived on Earth for so many years? What are some of the struggles plants face in obtaining daily needs like sunlight, water, space, etc. Today we will learn how plants have adapted to survive environmental pressures. Be prepared to: Describe how specific species of plants have adapted to survive in their habitats. Grab one of each sheet off of the front table. Define the following terms. Be sure to include what it is, what instrument you use to measure it, and in what units of measurement. MASSWEIGHTVOLUMEDENSITY- OBJECTIVE: Analyze structural, behavioral, and physiological adaptations to predict which populations are likely to survive in a particular environment. Structural adaptations are traits that are part of the plant’s structure (external). Behavioral adaptations are the way something acts naturally or by instinct. Physiological adaptations is when a plant may change its interior body parts chemically. (internal) Adaptations to get food Leaves and stems absorb energy from the sun. Adaptations to get food Plants lean or grow towards the sun. Roots grow down into soil. Vines climb up trees to catch sunlight. Adaptations to get food Plants like the Venus fly trap, trap insects for food. Adaptations to get water and nutrients Roots soak up water and nutrients from soil. Adaptations to get water and nutrients Desert flowers can stay dormant for months, only coming to life when it rains. Adaptations for reproduction Brightly colored flowers with nectar attract pollinators such as birds, bees and insects. Adaptations for reproduction Sweet fruit attracts animals that spread seeds far away. Some seeds are shaped to catch the wind. Adaptations for reproduction Plants drop seeds to grow new offspring. Adaptations for defense Spines and thorns protect plants from predators Adaptations for defense Poison Ivy and Poison oak have toxins that give predators a painful itchy rash. Small leaves or spines on desert plants conserve water. Thick waxy skin holds in water. Roots near the soils surface soak up rain water quickly before it evaporates. Deep roots help plants survive prairie fires. Narrow leaves lose less water than broad leaves. Flexible stems bend in the wind. Small plants grow close to the ground for warmth. Dark colored flowers absorb heat from the sun. Fuzzy stems provide protection from wind. Smooth, slippery bark keeps vines from killing trees. Slide shaped leaves lets rain run off so fungus doesn’t grow on plants. Thick bark protects trees and dropping leaves in winter conserves water and nutrients during cold winters. Flexible stems move with water currents. Floating seeds spread offspring. What is a structural or behavioral plant adaptation that allows it to get water and nutrients? Adaptations for reproduction? Adaptations for defense? Desert adaptations??? Grassland adaptations? Rainforest adaptations? Complete the “Plant Adaptations” worksheet and bring to class tomorrow. Where will your plant grow?
