Question

Как растения засушливых мест приспособились к обитанию в них? Помогите пожалуйста

Answer 1

Ответ: Кактусы, алое и тд. Они не имеют большых лысьтьев из которых может испарятся вода. Цветут не круглый год ,а только когда влажный сезон, имеют глыбой корень

Adaptations of Plants to Arid Environments

Plants that inhabit arid or drought-prone areas have developed various adaptations to survive in these challenging conditions. These adaptations help them conserve water, tolerate high temperatures, and thrive in low-nutrient soils. Here are some key ways in which plants have adapted to arid environments:

1. Succulence: Many plants in arid regions have evolved succulent characteristics, which means they store water in their leaves, stems, or roots. These water-storing tissues allow them to survive during dry periods. Examples of succulent plants include cacti and succulent shrubs like aloe vera and agave.

2. Reduced Leaf Surface: To minimize water loss through transpiration, plants in arid environments often have reduced leaf surface area. This can be achieved through various adaptations, such as needle-like leaves or small, thick leaves with a waxy cuticle that reduces water loss.

3. Deep Root Systems: Plants in arid regions often have deep root systems that enable them to access water stored deep underground. These extensive root systems help them tap into water sources that are not available to shallow-rooted plants.

4. CAM Photosynthesis: Some plants in arid environments, such as cacti and certain succulents, use a specialized form of photosynthesis called Crassulacean Acid Metabolism (CAM). CAM photosynthesis allows these plants to open their stomata (tiny openings on the leaf surface) at night to take in carbon dioxide while minimizing water loss. During the day, the stomata remain closed to conserve water.

5. Drought-Tolerant Morphology: Plants in arid regions often have specific morphological adaptations to cope with water scarcity. These adaptations can include reduced plant height, spines or thorns to deter herbivores and reduce water loss, and a compact growth form to minimize exposure to sunlight and reduce evaporation.

6. Protective Hairs and Trichomes: Some plants have developed specialized structures like hairs and trichomes on their leaves and stems. These structures help reduce water loss by creating a boundary layer that traps moisture and reduces evaporation.

7. CAM Physiology: In addition to CAM photosynthesis, plants in arid environments may also exhibit CAM physiology. This involves closing their stomata during the day to prevent water loss and opening them at night to take in carbon dioxide.

8. Salt Tolerance: Some plants in arid regions, such as mangroves and saltbushes
