Mason places a water plant in a test tube of water. He places a stopper in the tube and turns it upside down in a rack by a sunny window. The next day, he sees bubbles in the water as well as in the top of the tube. What produced the bubbles

The water plant

Explanation:

According to this question, Mason performs an experiment where he places a water plant in a test tube of water and turns it upside down in a rack by a sunny window. However, the next day, he observed that there were bubbles in the water as well as in the top of the tube.

These bubbles were actually OXYGEN GAS produced as a result of a metabolic process carried out by the water plant called PHOTOSYNTHESIS. In photosynthesis, which is the process whereby plants synthesize their food in the presence of sunlight, OXYGEN gas is given off as a waste product. The oxygen gas is what was observed by Mason as bubbles. Hence, the bubbles were produced by the WATER PLANT.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
