Auxin is a plant hormone that regulates various processes like growth, development, and tropic responses. It works by promoting cell elongation, cell division, and is involved in root and shoot initiation. Auxin also plays a role in phototropism and gravitropism by regulating bending responses in plants towards light or gravity.
Root gravitropism is mainly controlled by the hormone auxin. The differential distribution of auxin across the root due to gravity is a key factor in causing roots to grow downward. The auxin gradient results in differential cell elongation on the upper and lower sides of the root, leading to root bending towards gravity.
Plants have different parts because they have evolved to adapt to their specific environments and functions. For example, plants in dry climates may have specialized leaves or roots to conserve water, while plants in low light conditions may have larger leaves to capture more sunlight. Additionally, different parts of a plant may serve different functions, such as roots for anchoring and nutrient uptake, leaves for photosynthesis, and flowers for reproduction.
It depends which plant you are referring to. Plants mature at different times of year.
A hormone called auxin, which is produced in the apical meristem or shoot tip of a plant, can affect the growth and development of other parts of the plant. It can regulate processes such as cell elongation, root development, and leaf growth. Auxin moves through the plant's vascular system and can affect different tissues and organs.
There are different plants with different parts but most plants have about 16 parts.

Why are the parts of some plants very different from those of others

Different parts take effect at different times. Some of the tax increases to pay for parts of it are starting to kick in this month (January '13).

The stem, roots, petals...These are several parts of a flower plant. However different plants vary in parts.
