Exposed to sunlight ---> Increased use of CO2 ---> ?
You are studying plants and your teacher has made a flowchart for a leaf. What phrase, if placed in box X, would correctly complete the flowchart above?
A. Increased amount of food production in the leaf because more carbon dioxide will increase the amount of photosynthesis occuring in the leaf.
B. Decreased amount of food production in the leaf because more carbon dioxide will increase the amount of photosynthesis occuring in the leaf.
C. Increased amount of food production in the leaf because more carbon dioxide will decrease the amount of photosynthesis occuring in the leaf
D. Decreased amount of food production in the leaf because more carbon dioxide will decrease the amount of photosynthesis occuring in the leaf.
When the plant is placed under the sunlight and the carbon dioxide, then an increased amount of food production occurs in the leaf because more carbon dioxide will increase the amount of photosynthesis occurring in the leaf, as is present in option A.
What is the role of photosynthesis?Photosynthesis is a process in which the plant needs carbon dioxide, sunlight, and water. When the plant is in normal condition and getting sufficient sunlight and carbon dioxide, the rate of photosynthesis increases, and the glucose synthesis increases too.
Hence, when the plant is placed under the sunlight and the carbon dioxide, an increased amount of food production occurs in the leaf because more carbon dioxide will increase the amount of photosynthesis occurring in the leaf, as is present in option A.

While playing basketball, a student scrapes their knee. Which explanation best describes what organelles work together for the skin to heal after being cut?
A. The cell membrane controls the amount of energy released so that the lysosomes can give the command for cellular reproduction.
B. The mitochondria provides the energy for the cell membrane to control the process of cellular reproduction.
C. The chloroplasts provide nutrients for the nucleus to give instructions to the other organelles so that cellular reproduction can occur.
D. The nucleus gives instructions to begin cellular reproduction and duplicates the DNA, and the mitochondria makes the energy necessary for the process.
The explanation best describes organelles work together for the skin to heal after being cut is the nucleus gives instructions to begin cellular reproduction and duplicates the DNA, and the mitochondria makes the energy necessary for the process. Thus, option D is correct.
What is RNA and DNA?Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded.
An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.
Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G). Friedrich miescher discovered DNA in the year of 1860.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure.
Therefore, the explanation best describes organelles work together for the skin to heal after being cut is the nucleus gives instructions to begin cellular reproduction and duplicates the DNA, and the mitochondria makes the energy necessary for the process. Thus, option D is correct.

How did the development of the cell theory lay the foundation for the current advancements in stem cell research?
All organisms depend on stem cells for their survival. As an outcome, stem cells may be a requirement for the evolution of specific characteristics in organisms that include regeneration, multicellularity and coloniality.
What is stem cell theory?The stem cell theory of ageing proposes that the ageing process is the result of the inability of different types of stem cells to continue to replenish the tissues of an organism with functional differentiated cells capable of maintaining that tissue's original function.
Thus, stem cells may be a prerequisite for the evolution of specific characteristics in organisms that include regeneration, multicellularity and coloniality.
