What type of root grows straight down deep into the ground answers com?
The taproot is the differentiated primary root that is thick and grows straight down deep into the soil. A few lateral roots grow off of this main root. The fibrous root consists of several roots of similar size and length that develop from the stem of the plant; the primary root does not remain.
Which root grows deep into the soil?

Most tree roots spread 2-3 times the radius of the canopy, and often reach out 5 times the radius of the tree canopy or more in dry conditions. So, for example, if a tree is 6m wide, the radius of the canopy is 3m. The root spread = 2 (to 3) x canopy radius = 2 (to 3) x 3m = 6m (to 9m).
