What do cacti do to survive in the desert?
they conserve their water
How do cacti reduce water loss?
Cactus are able to conserve water due to their stems. They have stems that are able to store water for when it is needed.
How are cacti such perfect desert plants?
Cacti are perfect desert plants because they thrive in dry climates. They receive their light from the sun through their stem. They don't have leaves so they conserve water.
Why does the cacti lack a spongy layer?
Cacti lack a spongy layer in their stems because they have adapted to hot, dry environments with limited water availability. The absence of a spongy layer reduces the surface area for water loss through transpiration, helping cacti conserve water and survive in arid conditions.
How would the lack of leaves help cacti survive?
Cacti have adapted to store water in their stems instead of leaves, which helps them survive in dry conditions. This reduces water loss through transpiration and allows cacti to thrive in arid environments by storing water for long periods. Additionally, the lack of leaves minimizes the surface area for evaporation, helping cacti conserve water.
Why do cacti have ridges?
Cacti have ridges, or ribs, in order to expand and contract as they store or conserve water. These ridges allow the cactus to swell when it absorbs water and shrink when it is dehydrated, helping it to survive in arid environments by maximizing its water storage capacity.
How does photosynthesis occur in cacti and what adaptations do they have to thrive in arid environments?
Photosynthesis in cacti occurs similarly to other plants, where they use sunlight to convert carbon dioxide and water into glucose and oxygen. However, cacti have unique adaptations to thrive in arid environments, such as their ability to perform photosynthesis at night to conserve water, their reduced leaf surface area to minimize water loss, and their ability to store water in their stems for long periods of time.
Why does cacti have thick stem?
In cacti the leaves have become reduced ( to prevent water loss via transpiration) and the stem has become the photosynthetic body. Being in the stem there are no or very few stomata ( where water is lost from) and the water is able to be stored in the stem to help it survive long times without water. I researched this online this is not my work!
What type of vegetation region has sparse plant life with scrub brush and cacti?
A desert vegetation region typically has sparse plant life with scrub brush and cacti. These regions are characterized by low precipitation levels and high temperatures, which are ideal conditions for plants that have adapted to conserve water, such as cacti and other succulents.
What plant has a higher rate of transpiration water lily or cactus?
Water lilies have a higher rate of transpiration compared to cacti. This is primarily due to their aquatic environment and large, broad leaves that facilitate water loss through evaporation. In contrast, cacti are adapted to arid conditions and have specialized structures, such as thick, waxy skin and reduced leaf surface area, to minimize water loss and conserve moisture.
Is it true that cacti are full of sand?
no, it is not true. Cacti are full of water.
Why do cacti have hair?
Cacti have hairs to not remove too much water .
