Question

compare the student text with the source.
source: hunter gatman-stanford,
ead my rings: the oldest living tree tells all.\ published on collectors weekly, 13 nov. 2012.

technically, the oldest of all trees are actually clonal plants, or those which continually replicate themselves through layering (where a limb sprouts new roots) and vegetative cloning (where the root system expands underground and sends up new trunks).

student text:

clonal plants are among the oldest trees because they are able to reproduce by forming new roots from limbs (a process known as layering) as well as by forming new trunks from a trees roots (a process known as vegetative cloning).

is the student text plagiarized?
no, it is not plagiarized.
yes, because it fails to cite the source.

Explanation:

The student text uses the core specialized information (definitions of layering and vegetative cloning for clonal trees) directly from the source without attributing it, which constitutes plagiarism as it does not give credit to the original source material and author.

Answer:

Yes, because it fails to cite the source.
