1 PLANT ADAPTATIONS Talk about the plant parts you see in front of you PLANT ADAPTATIONS Talk about the plant parts you see in front of you. What adaptations of roots, stems, leaves, flowers, fruits and seeds allow the plants to meet their needs in their habitats?

3 Plant Adaptations Plants have traits, or adaptations, that allow them to meet their needsin a specific habitat.
4 How do adaptations help plants survive in their habitats?
6 Root AdaptationsRoots take in water and nutrients from the soil and hold the plant in place. Roots also store food and water.Some cacti have roots close to the surface for living in dry habitats. Their short, shallow roots take up water quickly from the habitat.Water lilies have deep roots that can reach down into the mud of the pond.
7 Carrots and dandelions have one long thick root, called a tap root. Anchors the plant in the soil.Reaches far down to absorb water.Dandelion RootCarrot root
10 Stem AdaptationsStems move and store water and nutrients in the plant. Stems also provide support and protection for the plant during its life cycle.Vines have stems that can climb so that the leaves are exposed to light.
11 Stem AdaptationsSome stems have briars to deter animals from eating the leaves.Some stems have tendrils to help climb toward light.
12 Stem AdaptationsCorn and sunflowers have stems that grow thick and strong but are still green and flexible so that they can grow toward the sun.
13 Stem AdaptationsTrees develop woody stems to support their size and offer protection during their long life cycles.
14 Stem AdaptationsCacti have thick stems that store water when the habitat does not provide it.
16 Leaf AdaptationsLeaves use light to make food. Each variety of plant will survive where its leaf size, texture, thickness, and shape are adapted to the habitat. Different kinds of plants have different sizes and shapes of leaves.
23 Flower AdaptationsFlowers often have special sizes, smells, shapes, or colors that attract organisms for pollination.TomatoMorning glory
24 Fruit AdaptationsFruits are formed around the seeds to protect them. Some fruits are moist and fleshy (tomatoes, grapes, or peaches).Others fruits are dry and hard (for example, coconuts, walnuts or pea pods).
26 Seed Adaptations Some seeds germinate as soon as conditions allow. Seeds have adaptations that allow them to be dispersed.Seeds have enough food for the plant until it begins making food of its own.

31 Working with a partner, design a wind dispersed seed structure that will carry a single seed (dried lima bean) the farthest distance possible.You will be given one sheet of white 8 1/2 by 11 paper, a pair of scissors, plastic tape, and a one seed. You may not use more than one sheet of paper but you do not have to use all the paper. You may cut, fold, tear, and/or tape your paper in any manner you choose provided your seed is fixed to the seed structure and does not fall out.After you have completed the design and assembly of your seed structure, it will be dropped in front of a fan, and the distance it travels will be recorded. Each seed/seed structure will be dropped 3 times, and the average distance traveled for the three trials will be calculated.
