Roots serve two purposes.
To supply the tree with nutrients and to anchor the tree and keep it upright. The spread will depend on the prevailing conditions i.e. how much wind it faces.
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.
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.
When grass is cut, it stimulates the plant's growth response, encouraging it to spread and proliferate. Cutting the grass removes the tips of the blades, which are responsible for photosynthesis; this prompts the plant to send out new shoots and roots to compensate. Additionally, the open space allows for better light penetration and air circulation, promoting further growth and expansion. As a result, grass can become denser and spread more effectively after being mowed.
Tap roots
Abscisic acid is produced by some plant roots.
they spread out and cover a large surface area which helps the roots take in water from the soil more quickly.
Potential lack of nutrients, but the question is very vague
Large crabgrass has a fibrous root system. The roots of large crabgrass spread horizontally near the soil surface, forming a dense network of fibrous roots to help the plant absorb water and nutrients efficiently.
The roots of a tree serve two purposes, one to anchor the tree and stop it blowing over,two to supply the tree with nutrients. It will therefore where possible send out roots as far as necessary to carry out both functions.
they have roots near to the surface and spread out far to make gooduse of any rainfall, but this leaves the trees prone to strong winds
Yes they do spread out in search of water and minerals
In the summer, moose scavenge around for berries and roots to grow as large and strong as they can for mating season in the fall.
The roots of a deodar cedar tree would likely not spread out any wider than the base of the tree. They would not spread out and make new trees.
Gumamela, also known as hibiscus, has fibrous roots. These roots help the plant absorb water and nutrients from the soil, providing support for the plant above ground. Fibrous roots are usually shallow and spread out widely to maximize water and nutrient uptake.
Cabbage plants have fibrous roots. Fibrous roots are a type of root system where roots branch to form a dense network, providing strong anchorage and efficient absorption of water and nutrients. This is in contrast to tap roots, which have a main root that grows vertically downward with smaller lateral roots branching off. In the case of cabbage, its fibrous root system helps support the plant's large, leafy growth above ground.
'If roots strong, tree survive.' 'Root karate come from Miyagi' 'This bonsai have strong root. Same you' Bonsai tree survives if it has strong roots. Daniel's karate survives because it has strong roots.
Trees are supported by their roots. in the open a tree will have a greater root spread than in a forest as it has no protection from wind. I n a forest protection is afforded by surrounding trees therefore such a large root spread is not required.
