The primary function of stems is to

Its main function of the stem is to support the leaves, flowers, branches and fruits, bind to the roots and conduct the sap (water and mineral salts).

Explanation:

The stem is a part of the plant that mainly has the function of conducting substances and supporting the leaves. It is an organ that along with the leaves make up the stem system. The stems and their leaves are closely associated in their development. The leaves sprout in the peripheral region of the stem and are arranged according to the organization of their vascular system.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
