Plants Adaptations to Water

All living organisms live in an aqueous environment. In our video we explored plant adaptations to water. In order for plants to be healthy they need to maintain one hundred percent humidity. We discussed plants that live in water saturated environments and plants that live in drought like conditions. The Salvinia is a plant that lives in a water-saturated environment. In our video we spoke about how the Salvinia is epiphytic (lives without roots) and absorbs water through brown hairy extensions. We also spoke about plants that live in dry conditions and are forced to focus on water conservation. The adaptations that we explored were: reduced surface area, hairiness, waxy cuticle, seeds, and sunken stomata. We said that a reduced surface area is important because it minimizes the amount of water loss from the leaf. Plants that are hairy slow water loss because the hair provides an obstacle. The waxy cuticle is important because it repels water form the inside and the outside. Seeds are important because they are drought resistant and store the next generation of plants. The sunken stomata are an interesting adaptation because it keeps the stomata humid and minimizes water loss during photosynthesis. All of these adaptations are important in order for plants to be healthy and able to produce the next generation of plants. We hope you enjoy our video!
