In botany, a tree is a perennial plant with
an elongated stem, or trunk,
supporting branches and leaves in most species.
A flower, sometimes known as a bloom or blossom,
is the reproductive structure found in plants
that are floral.
A leaf is an organ of a vascular plant
and is the principal lateral appendage of the stem.
The leaves and stem together form the shoot.
Animals are multicellular,
eukaryotic organisms of the kingdom Animalia
(also called Metazoa).
