Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy into chemical energy stored in sugar molecules. This process is fundamental to life on Earth as it provides the primary source of energy for nearly all organisms. The energy is captured from sunlight by a pigment in the plants called chlorophyll, which gives plants their green color.
During photosynthesis, carbon dioxide from the air and water from the soil react in the presence of light to form sugars and oxygen. The oxygen is released into the atmosphere, which is crucial for the survival of most life forms on Earth. The sugars produced are used by the plant for energy and growth, storing excess energy as starch.
The process occurs in two main stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy in the form of ATP and NADPH. The Calvin cycle uses the ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.
Photosynthesis not only sustains plant life but also maintains the atmospheric oxygen levels and is a key factor in the carbon cycle, helping to regulate Earth's climate.
Why is photosynthesis important for life on Earth?
- A. It helps plants grow faster
- B. It maintains atmospheric oxygen levels
- C. It increases water availability in the soil
- D. It decreases carbon dioxide levels
Correct Answer: B
Rationale: Photosynthesis is crucial for life on Earth because it maintains atmospheric oxygen levels. During photosynthesis, plants, algae, and certain bacteria convert light energy into chemical energy stored in sugars, releasing oxygen into the atmosphere. This oxygen is essential for the survival of most life forms on Earth. While photosynthesis does support plant growth and energy storage, its primary significance lies in its role in oxygen production, which is vital for sustaining life on our planet.

Searching for medical information can be confusing, especially for first-timers. However, if you are patient and stick to it, you can find a wealth of information. Your community library is a good place to start your search for medical information. Before going to the library, you may find it helpful to make a list of topics you want information about and questions you have. Your list of topics and questions will make it easier for the librarian to direct you to the best resources. Many community libraries have a collection of basic medical references. These references may include medical dictionaries or encyclopedias, drug information handbooks, basic medical and nursing textbooks, and directories of physicians and medical specialists (listings of doctors). You may also find magazine articles on a certain topic. Look in the Reader’s Guide to Periodical Literature for articles on health and medicine from consumer magazines. Infotrac, a CD-ROM computer database available at libraries or on the Web, indexes hundreds of popular magazines and newspapers, as well as medical journals such as the Journal of the American Medical Association and New England Journal of Medicine. Your library may also carry searchable computer databases of medical journal articles, including MEDLINE/PubMed or the Cumulative Index to Nursing and Allied Health Literature. Many of the databases or indexes have abstracts that provide a summary of each journal article. Although most community libraries don’t have a large collection of medical and nursing journals, your librarian may be able to get copies of the articles you want. Interlibrary loans allow your librarian to request a copy of an article from a library that carries that particular medical journal. Your library may charge a fee for this service. Articles published in medical journals can be technical, but they may be the most current source of information on medical topics.

What would likely happen if chlorophyll were absent in plants?
- A. The rate of photosynthesis would increase
- B. Plants would not be able to capture light energy effectively
- C. Plants would produce more oxygen
- D. The Calvin cycle would be more efficient
Correct Answer: B
Rationale: If chlorophyll were absent in plants, they would not be able to capture light energy effectively. Chlorophyll is the pigment responsible for absorbing light energy during photosynthesis. Without chlorophyll, plants would lack the key component needed to convert light energy into chemical energy, resulting in a significant impairment of the photosynthesis process. This would lead to a decrease in the plant's ability to produce sugars and oxygen, ultimately impacting their growth and survival. Therefore, option B is the correct answer as the absence of chlorophyll would hinder the plant's ability to capture light energy efficiently.
ALL THE JAZZ
Jazz has been called "the art of expression set to music", and "America's great contribution to music". It has functioned as popular art and enjoyed periods of widespread public response, in the "jazz age" of the 1920s, in the "swing era" of the late 1930s and in the peak popularity of modern jazz in the late 1950s. The standard legend about Jazz is that it originated around the end of the 19th century in New Orleans and moved up the Mississippi River to Memphis, St. Louis, and finally to Chicago. It welded together the elements of Ragtime, marching band music, and the Blues. However, the influences of what led to those early sounds goes back to tribal African drum beats and European musical structures. Buddy Bolden, a New Orleans barber and cornet player, is generally considered to have been the first real Jazz musician, around 1891. What made Jazz significantly different from the other earlier forms of music was the use of improvisation. Jazz displayed a break from traditional music where a composer wrote an entire piece of music on paper, leaving the musicians to break their backs playing exactly what was written on the score. In a Jazz piece, however, the song is simply a starting point, or sort of skeletal guide for the Jazz musicians to improvise around. Many of the early Jazz musicians were bad sight readers and some couldn't even read music at all. These early musicians couldn't make money very much and were stuck working menial jobs to make a living. The second wave of New Orleans Jazz musicians included such memorable players as Joe Oliver, Kid Ory, and Jelly Roll Morton. These men formed small bands and took the music of earlier musicians, improved its complexity, and gained greater success. This music is known as "hot Jazz" due to the enormously fast speeds and rhythmic drive.

A young cornet player by the name of Louis Armstrong was discovered by Joe Oliver in New Orleans. He soon grew up to become one of the greatest and most successful musicians of all time, and later one of the biggest stars in the world. The impact of Armstrong and other talented early Jazz musicians changed the way we look at music
