plants adaptation and gas exchange

• The stomata are the openings on the underside of leaves that allow gases to enter or exit.
• Leaves may also be shaped differently for different purposes, such as wide and flat to maximize photosynthesis or long and narrow to reduce water loss.
• Plants have evolved various adaptations to cope with environmental stresses such as drought, high temperatures, low nutrient availability, and herbivores.
• Plants have evolved various adaptations to cope with environmental stresses like drought, extreme temperatures, and high light intensity.
• In the desert, the day and night temperature is extreme and the amount of rainfall is low.
• The pole is extremely cold, and the area is covered with ice all year long. The amount of rainfall there is also rare and the winters are long,dark and cold but the summers are cold and short.
• Cacti store water in their stems and have spines instead of leaves to minimize water loss through transpiration.
• Different types of plant species have adapted to survive in these environments by developing unique features.
• Tropical rainforests have high temperature all year round and the amount of rainfall is also high.
• lenticels on tree trunks carry out gas exhange
• the guard cells control the opening and closing of stomata
• stomata open during the day when photosynthesis occurs
• transpiration is the evaporation of water from the surface of the leaf
• stomata close at night time as no photosynthesis takes place
