Biology
1 answer:
Dovator [93]3 years ago
6 0

Answer:

<em>The correct option is D. It is carbon dioxide released by respiration.</em>

Explanation:

The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.

Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.

What role does transpiration play in the water cycle
Airida [17]

Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. Transpiration is essentially evaporation of water from plant leaves. Transpiration also includes a process called guttation, which is the loss of water in liquid form from the uninjured leaf or stem of the plant, principally through water stomata.

Studies have revealed that about 10 percent of the moisture found in the atmosphere is released by plants through transpiration. The remaining 90 percent is mainly supplied by evaporation from oceans, seas, and other bodies of water (lakes, rivers, streams).

Transpiration and plant leaves

Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions, such as temperature, humidity, sunlight availability and intensity, precipitation, soil type and saturation, wind, land slope, and water use and diversion by people. During dry periods, transpiration can contribute to the loss of moisture in the upper soil zone, which can have an effect on vegetation and food-crop fields.
