The banana plant is called a 'banana tree' in popular use, but it's technically regarded as a herbaceous plant (or 'herb'), not a tree, because the stem does not contain true woody tissue.
The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.
An atom is made up of protons and neutrons in a nucleus, surrounded  by smaller electrons. It takes 1830 electrons to make up the mass  of one proton, so the majority of theâ¦ mass is in the nucleus.
