Plant Adaptations WebQuest—Answer Key Go to http://www.mbgnet.net/bioplants/adapt.html to find the answers! 1. What are adaptations? Adaptations are special features that allow a plant or animal to live in a particular place or habitat. 2. What is a biome? A biome is a place characterized by its climate and the plants and animals that live there. 3. Investigate an extreme condition of the biome and determine the plant’s adaptation to survive in that extreme condition. Biome Desert Grassland Extreme conditions of that biome Very dry and HOT Direct sunlight to plants Soil is rocky and cannot hold much water Strong winds Hot summers, cold winters Drought is common Rich soil Good for agriculture Plant adaptations for survival Spines instead of leaves Light-colored hair to shade Waxy coating to reduce water loss Tropical Rain Forrest Temperate Rain Forrest HOT Lots of rain—leads to growth of bacteria and fungi Poor soil Little sunlight at ground level Lots of precipitation Poor soil Tall evergreens are dominant Soft stems to bend in wind Wind pollinated plants Roots survive fires to sprout again Shrubs re-sprout after fire Drip tips and waxy surfaces allow rain to run off Plants grow on or climb on other plants to be higher Shallow roots to get nutrients Trees go tall due to precipitation Slow decomposition to get nutrients from fallen logs Plants grow on top of each other to reach Reason for that adaptation Temperate Deciduous Forrest Taiga (Boreal Forest) Tundra Hot in the summer, freezing in the winter Plentiful rain Tall trees cover small trees—levels of plants Coniferous trees are dominate Cold winters, warm summers Some are permanently frozen Poor soil (acidic) Cold year round— permanently frozen sub-layer Poor drainage Slow evaporation Little diversity In Water sunlight Wildflowers grow earlier in season before tree leaves spread out Light-weight leaves to capture sunlight Thick bark on trees to protect from winter Plants can photosynthesize quickly due to trees being coniferous Needle-like leaves lose less water and shed snow Dark colored needles to absorb more sunlight Low growing plants to keep them from freezing Dark colored plants to absorb more solar heat Clumps of plants to protect from wind and cold Flexible stems and leaves to move with currents Leaves float on top of water to photosynthesize Some plants produce seeds that float 4. In which biome(s) would you find very small leaves (or needles)? Taiga 5. In which biome(s) would you find broad, or large, leaves? Temperate Deciduous Forrest 6. In which biome do you think it would be easiest for YOU to survive?
