What are 4 adaptations of a cactus?
A cactus has special adaptations in its roots, leaves as well as stems that enable it to thrive in desert environments. These adaptations include – spines, shallow roots, deep-layer stomata, thick and expandable stem, waxy skin and a short growing season.
What are two adaptations of cactus?
Spines which are modified leaves. These minimise the surface area and so reduce water loss. The spines also protect the cacti from animals that might eat them. Very thick, waxy cuticle to reduce water loss by evaporation .
What are 3 behavioral adaptations of a cactus?
Cacti have numerous anatomical and behavioral adaptations for absorbing and storing water, preventing water loss, protecting themselves from predators, limiting damage from the hot sun, saving their energy, requiring few resources, and attracting pollinators.
What are some physical adaptations of a cactus?
White dense spines help reflect sunlight! Spines provide shade! Cacti stem is thick and fleshy to store lots of water! Stem has waxy waterproof coating to help keep water in the cacti.
What are fish adaptations?
Fish have adapted to their environment through the evolution of gills, swim bladders and fins. Gills allow fish to absorb oxygen from the water, swim bladders allow fish to maintain an appropriate level of buoyancy and fins allow the fish to move through the water.
What adaptations help a cactus survive in the desert?
A cactus is able to survive in the desert due to the following features: (i) It has long roots that go deep inside the soil for absorbing water. (ii) Its leaves are in the form of spines to prevent water loss through transpiration. (iii) Its stem is covered with a thick waxy layer to retain water.
What adaptation helps cacti hold onto water?
Cacti have also developed succulent tissue, waxy skin, prickly spines, and a specialized root system to take every advantage in their harsh ecosystems. The stem acts as a reservoir; the plant will expand and contract depending on the amount of water it holds. The skin’s waxy coating helps retain moisture.
