The barrel cactus [Echinocactus and Ferocactusspp] has spreading, shallow, fibrous roots. It's the only kind of roots that a cactus plant has. The roots need to spread out in search of rare soil moisture. They also need to be shallow to catch the drops of dew, fog, or rain that drip to the ground and into the soil. They need to be fibrous, too, to take in water and dissolved nutrients, to send up the stem for the photosynthetic interaction with sunlight.
A barrel cactus [Ferocactus spp] has shallow, fibrous roots. It needs many, fine roots to take in the moisture that drips into the soil from condensation and from rainfall. It doesn't need swollen storage roots, because water is held in its thick walled, thick fleshed stem.
yes because it needs a lot of water
it absorbs more water
Cactus are a desert plant, and so need to send their roots deep down for their food.
shallow roots extend away from a plant long; thinck roots that grow deep
it wouldnt unless it rained alot and the rain was absorbed deep into the ground for the roots of the cactus to drink.
The size of the barrel cactus [Echinocactus and Ferocactus spp] depends upon the particular kind of cactus. For example, there are about 35 species within the genus Ferocactus. The species ranges from small, such as the 10 inch/25 centimeter crow's claw cactus [Ferocactus latispinus] to the tall, such as the 10 feet/3 meters candy barrel cactus [Ferocactus wislizeni].
it has long roots that edge into the ground so deep that they can find water and feed
No they don't. BEcause of their natural environment (the desert), where water is scarce, cacti develop shallow root systems. They are shallow, but they spread out, making it more likely that the plant would find surface water.
The roots to a cactus are long thick and go very wide and deep. When it rains the roots absorb the water and store it in its leaves. The cactus doesnt need a lot of water. A couple drops a year will keep it alive. Its leaves are protected with spines.
long roots that reach deep down
Cacti have very strong roots that go deep into the Earth searching for water. Since they go so far, they must be very strong. The stronger the roots, the deeper they search for water. Roots secure plants to the ground, but some can't. Cacti can.
Cactuses grow by storing water inside them. They barely need water, so it would be even easier.
This book is verry GOOD
