Spruce trees belong to the phylum Coniferophyta, which is part of the larger division of gymnosperms. This phylum includes various tree species that produce cones and have needle-like leaves, adapting them to various climates. Spruce trees are specifically classified under the genus Picea within this phylum.
Are you asking: "how long does a flatworm live?"If so, this is not an answerable question--there are too many types of flatworms to make a generalization.I personally know of one type of flatworm which can re-generate--cut off any part of it's body, and that part will re-generate. As long as the head remains attached, the re-generation can take place.I did a science project using freshwater planarians, where I explored this phenomenon.
