Mrs. Keadle JH Science Name__________________________________ period _____ date assigned_____________ date due ______________ date returned _____________ Plant Adaptations For each plant structure, write down its function and adaptations it can have to help the plant survive and reproduce. structure function adaptations root stems or trunk leaves flowers seeds 1 Plant Adaptations Mrs. Keadle JH Science Visual Vocabulary Below are vocabulary words and definitions. Your task is to draw a picture to demonstrate the definition. physiology The scientific study of an organism’s vital functions, including growth and development. phototropism geotropism external features function Movement or growth in response to lights or colors of lights. A plant whose roots grow down into the soil as a response to gravity. The outward appearance of a distinct part that can be seen, such as the roots, stem, leaf or flower of a plant. The physiological activity of a part (the specific role a part has in the system) 2 Plant Adaptations Mrs. Keadle JH Science Plants have different signals for attracting pollinators. It is not uncommon for the same plant to have more than one signal. Which of the following would NOT be a way in which plants attract pollinators? 16 17 A presence of barbs B specific texture or pattern C strong scents D bright colors Plant species rely on various methods of seed dispersal. Which type of seed dispersal would most likely be used by the organism shown in the diagram? F animal dispersal G wind dispersal H water dispersal J gravity dispersal 18 Trees that grow in a forest tend to grow very tall, with few branches. The same species of tree grown in an open area tends to grow shorter and wider, with many branches. The stimulus responsible for theses different growth patterns is the amount of A wind striking the tree B light reaching the tree C nutrients in the soil D water in the ground 3 Plant Adaptations Mrs. Keadle JH Science 19 20 The maypop flower is a long vine that grows along fences. These plants have tendrils that allow them to grab and hold onto the fences. How does this adaptation help the plant? F wrapping around a nearby object for support G producing reproductive structures later in the growing season H attracting insects which serve as pollinators J encouraging water and mineral transport to other parts of the plant Complex animals use their circulatory systems to provide their cells with water and food. Plants do not have circulatory systems. What have they developed to move nutrients and water. A xylem B cork cells C chloroplasts D flowers 21 An acorn is a seed. Its shape is very different from the shape of a dandelion seed. Which of the following BEST describes the advantage of the shape of the acorn? F The acorn is more likely to stick to animal fur. G The acorn is less likely to attract hungry animals. H The acorn can be blown to a better growing location. J The acorn stores more materials to help it start growing. 4 Plant Adaptations Mrs. Keadle JH Science 22 A spiny cactus is growing very successfully in an Arizona dessert. This plant has many adaptations to its native environment that make it successful in harsh conditions. Three adaptations that the spiny cactus has are A broad leaves, deep roots, sharp spines B waxy leaves, sharp spines to preserve moisture, a shallow root system C sharp spines, small bad tasting leaves, deep roots D large, shallow root system, sharp spines, thick trunk 23 Some species of flowers have markings that are visible only to insects with the ability to see ultraviolet light. These markings help the plant F avoid parasitic insects G attract pollen gathering insects H seek out moisture in the soil J create a strong scent to attract bats 5 Plant Adaptations
