Question

How the plant ensure that intake oxygen at sufficient level
​

Answer 1

Answer:

A human being uses about 550 liters of pure oxygen (19 cubic feet) per day 9.5 tonnes of air in a year, but oxygen only makes up about 23 percent of that air, by mass, and we only extract a little over a third of the oxygen from each breath. A 100-ft tree, 18" diameter at its base, produces 6,000 pounds of oxygen." "On average, one tree produces nearly 260 pounds of oxygen each year.

Answer 2

Plants take in oxygen through tiny pores on their leaves called stomata, which open and close to regulate the exchange of gases with the atmosphere. To ensure that they take in oxygen at sufficient levels, plants have evolved several mechanisms.

• One of these is the ability to adjust the size and number of stomata based on environmental conditions such as light, temperature, and humidity. This allows plants to optimize their gas exchange rates and conserve water during periods of stress.
• Plants also have specialized tissues such as the root system, which absorb oxygen from the soil and transport it to the rest of the plant. Additionally, many plants have symbiotic relationships with soil microorganisms that help them to absorb and fix atmospheric nitrogen, which is essential for plant growth.
• The intake of oxygen is crucial for plant respiration, which is the process by which energy is released from stored sugars to fuel the plant's growth and metabolism.
• Overall, plants have evolved a range of adaptive mechanisms to ensure that they can take in oxygen at sufficient levels to support their metabolic processes and ensure their survival.
