Q:

How does a plant's organ system work?

A:

Quick Answer

A plant's organ system works with the roots anchoring the plant and absorbing water and nutrients, while the shoots transfer the nutrients to the leaves, which transfer light into energy via photosynthesis. A plant’s roots, leaves and stems, the three basic plant organs, work together to allow the plant to function. The plant’s shoot system, which includes the leaves, stems, and flowers, is divided into two sections: the non-reproductive portion and the reproductive portion. The reproductive portion includes the flowers and fruit. The non-reproductive portion includes the leaves and stems.

A plant’s roots are not only used for water and nutrient absorption but also for food storage. The root’s xylem cells help transfer water and nutrients to the shoot system. The shoot system then transports the water and nutrients to the remainder of the plant, including the leaves and flowers. With nutrients and water, the chloroplasts of the leaves are well hydrated and ready for photosynthesis. During photosynthesis, the plant converts light energy into chemical energy to make sugar for the plant. This process occurs in the chloroplasts of the leaves. Later, any remaining sugar that is not used is transferred back down the shoot system to the roots of the plant. Usually, the bigger the plant, the stronger its root system with roots stemming deep into the ground.

    What are the two main functions of roots?

    A:

    The two main functions of roots are to deliver water and nutrients to the plant or tree and provide an anchor that keeps the plant or tree in the soil. Roots are generally the first part of any plant that emerges during germination.

    What is the role of xylem in a vascular plant?

    A:

    Xylem is a type of vascular tissue that is responsible for moving water through a plant from its roots to its leaves. Columns of xylem tissue begin in the root hairs and rise all the way up through the leaves of a plant.

    What is the process of transpiration?

    A:

    The process of transpiration is when water moves through plants from the roots to the leaves, then changes to vapor as it leaves the plant. Transpiration cools the plant and also provides it with nutrients, carbon dioxide and water.

  • Q:

    Why do leaves change color in the fall?

    A:

    When the abscission layer of a plant grows, it cuts off the circulation of nutrients, sugar and water to the leaves, which causes the chlorophyll that gives the plant its green color to disintegrate and makes carotene shine through. The result is the yellow-colored leaves that are found on maple and other trees, such as birch and aspen, in the fall.
