2 Store water in stems or leaves, succulents. No leaves, photosynthesis conducted in stem. Leaves grow only after heavy rain. Long, spreading root systems. Short life cycle occurs within one year. Germination occurs after heavy rain. Hair on leaves to shade the plant. Leaves turn during the day to minimize exposure to the sun. Spines to protect against animals that would eat the plant for water. Stems and leaves have waxy coating to reduce water loss. Flowers open at night attracting pollinators who are active during this cooler time. Slow growing requires less energy. Tropical Rain Forest Leaves shaped to allow for maximum run off of water. Vines climb on other plants to reach sunlight. Prop and stilt roots to support plants in the shallow soil. Low lying plants rely on animal pollinators due to a lack of wind. Tropical Rain Forest

3 Tropical Rain Forest Temperate Deciduous Wax on flowers and leaves to speed run off of water. Shallow roots to retrieve nutrients from the top layer of soil. Leaves gather water into a central reservoir where it is absorbed through hairs on the leaves. Leaves are dropped in the autumn and new ones are grown in the spring. Bark on trees is thick to protect against cold winters. Smooth bark to allow for run off of water. Aerial roots, which cling to host plant, absorb minerals and water from the atmosphere. Low lying plants grow early in spring before trees leafout and block the sun. Thin, broad, light-weight leaves to capture a lot of sunlight but also allow for water loss. Usually less than 12 inches tall due to lack of nutrients. Tropical Rain Forest Temperate Deciduous Short to prevent freezing. Dark in color to maximize absorption of solar heat. Low growing and small because roots cannot penetrate permafrost. Can be covered in hair for warmth. Grow in clumps to protect from wind and cold. Flowers are bowl shaped and follow the sun to stay warm.

4 Roots adapted to survive fire and sprout again. Trees may have thick bark to resist fire. Grassland Temperate Rain Forest Grasses with roots extending deep into ground to absorb moisture. Grasses with narrow leaves to prevent water loss. Wind pollination is common as area is typically windy. Mosses and ferns grow atop tall plants to reach light. Seedlings may grow on decomposing fallen logs to obtain nutrients. Evergreen trees to take full advantage of warm temperatures. Leaves with thick waxy coating to prevent evaporation. Root system is extensive to prevent grazing animals from pulling up plant. Grasses which grow from the base to avoid damage by grazing animals. Grasses with soft stems to allow for bending in the wind. Decomposition is slow due to cool temperatures. Large amount of precipitation results in tall trees despite cool temperatures. Needle-like leaves to prevent water loss and shed snow. Leaves are dark in color to allow for absorption of solar energy for heat. Grassland Temperate Rain Forest

5 Downward sloping branches help shed snow. Flexible leaves and stems to move with currents. Air spaces in stems for flotation. Reduced or absent roots and root hairs. Leaves float on surface to maximize absorption of sunlight. Absorption of water, nutrients, and dissolved gasses through leaves. Roots to provide anchorage. Seeds can float. Stomata may be concentrated on upper surface of leaf.
