When A Plant Part Undergoes Senescence The Nutrients May Be?

  1. When a plant goes through the process of senescence, the nutrients in the senescent sections of the plant may be removed and transported to the growing parts of the plant.
  2. The process of diffusion and active absorption by the cells of growing areas is what causes the mineral ions to be transported to the apical and lateral meristems, the young leaves, the forming fruits, and the seeds and storage organs of the plant.

When a plant component ages, it goes through a process called senescence, during which nutritional resources, such as minerals and carbohydrates, move away from the senescing part or are translocated to other plant parts. At the period of senescence, we notice the loss of chlorophyll, RNA, and protein in leaves, followed by the movement of nutrients and finally abscission.

When a plant undergoes senescence the nutrients may be a Accumulated B withdrawn C translocated D None of the above?

The process of senescence in plants might result in the nutrients being (a) accumulated; (b) bonded to the cell wall; (c) translocated; or (d) none of these. Senescence, sometimes known as the deliberate death of a plant, is the correct answer. During the senescence phase of the plant’s life, the process of translocating nutrients to the various portions of the plant stops.

Which mineral is not readily mobilized from older leaves undergoing senescence?

The right response, therefore, is ″Calcium.″

Which set of minerals are readily mobilized during senescence?

Calcium is a structural component that is not remobilized, whereas phosphorus, sulphur, nitrogen, and potassium are the elements that most quickly become mobilized.

What is nutrient remobilization?

When green plants experience a decrease in photosynthesis, remobilization of nutrients involves the participation of genes; this means that the maturity of plants implies that senescence (and, consequently, the mobilization of resources to new growth regions of plants) has begun (Biswal and Biswal, 1988).

Which of the following element accumulates in older leaves?

Both meristematic and developing tissues have a prerequisite need for calcium. It is more prevalent in leaves that are older.

What is meant by senescent?

(sen-ests) The process of getting older as one becomes older. Senescence is a process that occurs in biology whereby a cell matures and ceases to divide in an irreversible manner, but does not die. It is possible for significant numbers of aged cells, also known as senescent cells, to accumulate in the tissues of the body over time.

Why are nitrogen and phosphorus limiting nutrients?

Summary. The amount of nitrogen (N) and phosphorus that is present in terrestrial environments frequently acts as a limiting factor for plant growth (P) According to Liebig’s rule of the minimum, a plant’s development will be constrained by the nutrient that is in the least available supply in comparison to what the plant needs.

Why is mineral nutrition important in plants?

It is essential for the process of photosynthesis, which takes place during the photolysis of water. The production of chlorophyll requires the mineral in order to be successful. It does so by acting as a catalyst for the metabolism of nitrogen.

What is remobilization in plants?

  1. The ‘apparent remobilization’ method, which is the determination of the amount of total nitrogen present in the various plant organs at different times of development, and the ’15N long-term labelling’ method, which allows for the determination of fluxes, have both been utilized in the investigation of nitrogen remobilization in several different plant species.
  2. Both of these methodologies have been utilized in the investigation of nitrogen remobilization.

What is plant Guttation?

The ″Guh-TAY-shun″ pronunciation of the word ″guttation″ This refers to the process in which water escapes from a plant through the tips or edges of its leaves. The xylem, which is the primary water-transporting tissue of a plant, is where the water comes from. Stomata, which are very small pores found in a plant’s leaves and stem, are often responsible for the evaporation of excess water.

Which elements are Remobilized in plants?

Phosphorus, sulphur, nitrogen, and potassium are examples of elements that are very simple for plants to remobilize.
