Before you want the plant to flower, cut it back and induce a rest period when watering and fertilizer is reduced, and the plant is kept cool (about 50 F to 55 F). This adaptation allows the stems to hold more water during a rainstorm and contract during dry conditions to prevent water loss. Plants living in deserts need to reduce the loss of water because water is very scarce in deserts. Free Account Includes: Thousands of FREE teaching resources to download; ... Plant Adaptations in the Rainforest PowerPoint. The adaptations of barrel cactus are by far the most fascinating adaptations seen in plants. Anatomy and Adaptations: Cacti have many adaptations that allow them to live in dry areas; these adaptations let the plant collect water efficiently, store it for long periods of time, and conserve it (minimizing water loss from evaporation).. Cacti have a thick, hard-walled, succulent stem - when it rains, water is stored in the stem. The hygroscopic pressure is what holds the plant up erect, as it lessens the plant loses its … Plants need to adapt to the environment if they want to survive. This short video goes over some of the basic adaptations found in the plants and animals that live in the desert biome.

The video explains the different adaptations plants develop to survive in a particular surrounding or a habitat. Plants like the saguaro cactus have expandable stems that have a pleated structure that expands and contracts, similar to an accordion. Cacti make use of many structural adaptations, such as shallow roots, fixed spines and thick stems, to survive in the desert where there is minimal rainfall. Cactus Plant Adaptation Display Poster. Cactus Adaptations through Stems. They obtain moisture from the air and make food by photosynthesis. One common name for the plant is starfish cactus. For children, the discussion can revolve around adaptation. The reason of this difference is that the habitat of the cactus is the desert while a plant with leaves has humid and fair climates. Shallow roots also allow for easy transportation to a better environment. There are 3 main types of adaptations found in organisms: Structural adaptation Saguaros have barrel-shaped bodies with peripheral stems referred to as arms. Root Adaptations in Desert Plants Cactus owe their success in the desert to their structural adaptations. Other specific desert plant adaptations follow: Cacti - Cactus pads are modifi ed stems with a waxy coating. Example: different types of Cactus, Joshua tree etc. This cactus only grows in the archipelago of the Galapagos Islands. The spines of the saguaro protect it from animals that would otherwise eat the saguaro, or use it as a water source, and they help provide protection from the sun. Both plant species have extensive root systems, located just beneath the soil surface. Adaptations can include such traits as narrow leaves, waxy surfaces, sharp spines and specialized root systems. They later dry up. This lead to many different adaptations in the plant. Some of these include different methods of water storage, photosynthesis, and alternative means of reproduction. As an example of plant adaptations, we are going to explain how cacti have adapted themselves to live in such arid conditions. 2. Such places have hot climate but have heavy rains. Overview Saguaro Cactus (Carnegiea gintantea) is native to the state of Sonora in Mexico and some parts of California and Arizona in the United States. Types of Adaptation. So the plants here have drip tips and waxy surfaces on leaves to shed the excess water. Or, have you ever thought about how cactus survive without water and why some plants are poisonous?
