Growth (shoot and root)

As the plant continues to grow, there are spots where the plant seems to be growing more rapidly that other parts. The meristem is when a section of the plant grows rapidly at a different pace than the rest of the plant, giving it uneven growth. The plant has two types of growth, primary and secondary. Primary growth is growing up for shoots, and down for roots. Primary happens both in monocots and dicots. Secondary growth is when the plant on grows from the girth and makes itself wider. This type of growth only occurs in dicots. Secondary growth fits in with vascular cambium because it is a secondary meristem that produces xylem and phloem. This is comparable to cork cambium because it is the same thing, expect for it produces cork which will then replace the epidermis. To be a strong plant, it needs important hormones such as auxin. Auxin is responsible for the growth and development of the plant such as the rate of cell differentiation. Other hormornes may include ABA which also helps with the growth and development which is responsible for bud dormancy. There many some problems with the growth of the plant due to the environment. Tropism is when there is a change of growth due to environmental factors such as a tree growing upside down due to gravity. Gravity will have effects of the baby plants as well. Although they won’t be growing upside down, they will have to grow stems strong enough to support itself.
