Cactus plants adapt to their extreme habitats by specializing body parts and functions. For example, the roots concentrate on anchoring the plant and on capturing nutrients and water from the soil. The stem concentrates on processing and storing water, nutrient solutions, and energizing starches and sugars. It also concentrates on controlling breathing, gas exchanges, and water loss through its pores, or stomata. It concentrates too on the photosynthetic interaction with sunlight. And the modified leavesconcentrate on directing moisture down to the ground, to be taken in by the cactus' roots.
They have prickles to protect themselves.
In a desert, they adapt so that they are able to hold in and store more water. For example, there is a cactus.
Plants are not intelligent, and are not capable of learning.
It's difficult to estimate how many cactus plants are in the United States of America. A census needs to include their native habitats, which tend to be in the southwest. But that census needs to factor in the non native habitats into which cactus plants are able to expand due to their high adaptability. It also needs to consider all of the florists, gardeners, nurseries, parks, plant sections and stores, and public gardens where cactus plants are being grown.
Leaves have evolved into spines on the cactus.
By evolution
Cactus, like other plants, uses photosynthesis to get energy.

Plants don't really have enemies, they need other animals to spread out further. But some do adapt to grow thorns and spikes, The cactus plant is a prime example of this.
Cacti grow flowers to reproduce and produce seeds. The bright, showy flowers attract pollinators like bees and butterflies, which transfer pollen between cactus flowers, allowing them to be fertilized and produce seeds for new cacti plants to grow.

Yes, some cactus plants can be toxic to cats if ingested. It is important to keep cactus plants out of reach of cats to prevent any potential harm.
no,there would be little change because the cactus wont be able to adapt to the environment.
