What are the plant part functions?

Answer 1

• The root, which holds the plant in place and allows it to draw nutrition and minerals needed for growth, might vary in its function according to its broader classification. For example, dicotlydon plants tend to develop tap roots that are a main root with a few smaller roots. Carrots are types of tap roots. A tap root is a type of storage root, which is an adaptation that allows a plant to store energy for later growth. The American yam or sweet potato is also a type of storage root and is also a dicot plant. Legumes are special members of the dicots because the roots have nodules in which a special fungus works in cooperation with the plant to help it fix nitrogen as an energy source.

Monocot Roots

• Adventitious roots are bunches of fine roots extending in in a network in all directions from the plant. Monoctlydons tend to develop adventitious roots. Sometimes these roots grow above ground and are called "prop" roots.

Stem

• The stem of the plant allows it to grow upright, and is a transport system for the water and minerals coming from the ground. Cells called xylem are stiff cells within the structure of the plant that also allow for the flow of water from the root to the leaf. Cells called phloem, which also exist in the stem of the plant, allow for the flow of nutrients from one part of the plant to the other. In monocots, these vascular cells are scattered evenly throughout the stem of the plant, whereas in a dicot, these cells are arranged in an orderly circle corresponding to the shape of the stem.

• Secondary Growth

  • Water and nutrient transport cells can also allow the plant to grow bigger year by year. This enlargement is called secondary growth. Woody plants, including trees, which get bigger year after year, tend to be dicots. However, although some plants might be in a different classification altogether, they'll have characteristics or traits that resemble one another even though their genetic makeup is entirely different. This phenomenon is called convergence. Palm trees, although they resemble dicot trees in their height and growth, are a famous monocot exception of plants exhibiting secondary growth.

  Leaves

  • The leaves of the plant create the energy, through photosynthesis, that the plant needs. In monocots, the veins of the leaf tend to be parallel to one another, whereas dicot leaves generally have a network of veins in the leaf. Leaves have holes though which water is drawn up through the plant. Leaf buds form in an area of the stem called the axil. The apex, or tip of the shoot, influences the development of the leaves in the apex, and also controls the shape of the plant through the release of hormones that determine when and where the leaves of the plant start to grow.

  Flower

  • The flower is the site of sexual reproduction for the plant. Monocot flowers tend to have multiples of three petals whereas dicot flowers tend to have multiples of five petals. The female part of the flower is the style, and the stamen is the male part of the flower. Weather and the insects are responsible for transferring pollen from one plant to another during fertilization. This process is called cross pollination. After the flower is fertilized, the ovary of the plant matures, and either becomes what we sometimes think of as a nut, a fruit or a vegetable. Tomatoes, apples, almonds are all ripened ovaries. All of these items contain the seeds that will generate the next plant
