How do photosynthesis and respiration minimize the production of excretory matter in plants?

Plants utilize the following strategy to eliminate excretory products: I The stomata extract oxygen, which is a byproduct of photosynthesis. (ii) Stomata are also responsible for the removal of carbon dioxide generated during the respiration process. Thus, plants maintain an optimal CO2 concentration in their cells by closing the stomata when atmospheric levels drop and opening them when they rise again.

Photosynthesis and Respiration are two important processes in plant metabolism. These processes use the chemical energy from the bonds between atoms in water and carbon dioxide to produce glucose and other organic compounds. As organisms must consume energy to live, they cannot avoid using up some of the energy stored in their food. The way that plants balance these demands is by regulating their internal environment so that both photosynthesis and respiration are stimulated at the same time.

During photosynthesis, electrons are transferred through the electron transport chain from water to carbon dioxide, resulting in the formation of carbohydrates. This process requires a lot of energy and generates heat as a by-product. To release this heat, plants create transpirationaly active compounds called "exudates", such as elaiosomes, which are proteinaceous casings surrounding certain insects that allow them to conserve water while still getting enough nutrition to reproduce.

In addition, plants need to be careful not to retain too much carbon dioxide during photosynthesis.

What are the modes of excretion in plants?

As a result, the following are some of the techniques utilized by plants to dispose of their waste products:

  • Gaseous waste through stomata and lenticels.
  • Stored solid and liquid waste by shedding leaves, peeling of bark and falling of fruits.
  • By secreting waste in the form of gum and resins.
  • Excrete waste into the soil around them.

How do plants excrete?

Plants expel their waste in the following ways: The primary waste products are CO2, H2O, and O2, with water and gaseous waste products discharged by stomata and lenticels. Many plants use resins and gums to store waste. Plants emit waste chemicals into the earth surrounding them as well. These emissions are called plant toxins.

Some plants absorb minerals from the soil and then discharge these minerals through their roots. For example, alfalfa absorbs potassium and magnesium from soil and emits these when they are needed by the plant. This is called "nutrient-up-cycling." Other plants absorb nutrients at random times during their growth period and retain them for later use. For example, corn stores nitrogen from the soil until it needs it for growth. When corn is grown in a field where nitrogen has been applied previously, it will use this stored nitrogen instead of having to absorb some when it starts growing again.

Still other plants get rid of waste products by expelling them into the air or underground. For example, trees release gas molecules through their leaves and branches into the atmosphere. These gases include CO2, which plants make as part of their normal metabolism; N2, which is the main component of air; and CH4, which animals produce as waste products that plants can use as fuel.

Plant toxins are poisons that plants create to protect themselves against predators.
