Hello it is 11:51pm I am tired
it's true
Answer:
The correct answer will be option-
1. Carbon dioxide concentration
2. Light intensity
Explanation:
A limiting factor is a factor which when present in the limited amount limits the metabolic process.
Photosynthesis is a complex process which converts the light energy to the chemical energy converting the carbon dioxide in the presence of sunlight to useful chemical metabolites like glucose.
The photosynthesis process is limited by the concentration of carbon dioxide and light intensity.
The low concentration of carbon dioxide and low light intensity availability decrease the rate of photosynthesis.
Thus, the selected options are correct.
Answer:
"One gene, one enzyme" hypothesis says that one gene encodes for one protein which performs a specific function in the living organisms. This study, published in 1941, was one of the most influential studies of the age and for that, Beadle and Tatus also received Nobel Prize.
However, in recent years, it has been well studied that many enzymes are encoded by more than one gene (or cluster of genes). There are some enzymes that are produced by a single gene; nevertheless, it has been concluded that the hypothesis is not completely true. But it is also important to say that this study set the baseline for the study of many biochemical processes in living organisms.
The apoplast in plant tissues consists of<u> cell walls, extracellular spaces, and vessel elements</u>
Explanation:
In plant cells, apoplasts refer to the extracellular space present outside the plasma membrane. These are formed by continuous cell walls arranged adjacent to each other.
The main function of apoplasts is transportation of water and other solutes between tissues and organs by free diffusion of molecules via the plasma membrane.
This pathway called the apoplastic pathway constituted by its vessel elements, cell walls, and extracellular space aids in passive absorption by roots
