Legume are valuable crops because they have protein-rich seeds and because_____
- A.
They improve the nitrogen content of the soil
- B.
Their leaves are used are herbs
- C.
Their leaves are fed to livestock
- D.
Their bark is a source of quinine
Correct Answer
A. They improve the nitrogen content of the soilExplanation
Legumes are valuable crops because they have the ability to fix atmospheric nitrogen through a symbiotic relationship with nitrogen-fixing bacteria in their root nodules. This process increases the nitrogen content of the soil, making it more fertile and beneficial for other plants to grow. This is why legumes are often used in crop rotation systems as a natural way to replenish soil nutrients and improve overall soil health.Rate this question:

_____ is the study of the interactions between plants and the environment.
Correct Answer
plant ecologyExplanation
Plant ecology is the study of the interactions between plants and their environment. It focuses on understanding how plants adapt to their surroundings, how they interact with other organisms, and how they influence and are influenced by abiotic factors such as climate, soil, and water availability. Plant ecologists study the distribution and abundance of plant species, as well as the processes that shape plant communities and ecosystems. This field of study helps us understand the dynamics and functioning of plant ecosystems and provides insights into conservation and management practices.Rate this question:

A(n) _____ is an undesirable plant that may crowd out crop plants or native plant species.
Correct Answer
weed
weedsExplanation
A weed is an undesirable plant that can compete with crop plants or native plant species for resources such as sunlight, water, and nutrients. Weeds can grow rapidly and spread quickly, which can result in reduced yields for crops or the displacement of native plants. Managing and controlling weeds is important in agriculture and conservation to ensure the health and productivity of desired plant species.Rate this question:

One of the inorganic nutrients recycled by plants is_____?
- A.
Cellulose
- B.
Gold
- C.
Phosphorus
- D.
Starch
- E.
Sugar
Correct Answer
C. pHospHorusExplanation
Plants recycle phosphorus as one of the inorganic nutrients. Phosphorus is an essential element for plant growth and development. It is a key component of nucleic acids, ATP (adenosine triphosphate), and phospholipids. Plants obtain phosphorus from the soil in the form of phosphate ions. They absorb it through their roots and use it to carry out various metabolic processes. Through the process of nutrient cycling, plants take up phosphorus from the soil, incorporate it into their tissues, and release it back into the environment when they die and decompose. This allows phosphorus to be reused by other organisms in the ecosystem.Rate this question:

Most of the problems associated with hay fever are caused by_____?
- A.
Airborne pollen
- B.
Cotton clothing
- C.
Ingested berries and fruits
- D.
Skin contact with weeds
- E.
A and B are correct answers
Correct Answer
A. Airborne pollenExplanation
Most of the problems associated with hay fever are caused by airborne pollen. Hay fever, also known as allergic rhinitis, is an allergic reaction to pollen from trees, grasses, and weeds. When a person with hay fever inhales pollen, their immune system overreacts and releases histamine, leading to symptoms such as sneezing, itching, and a runny or stuffy nose. Therefore, airborne pollen is the main culprit behind hay fever symptoms.Rate this question:

Which of the following is NOT likely to cause hay fever?
- A.
Cereal Crops
- B.
Deciduous trees
- C.
Large flowers
- D.
Wild grasses
Correct Answer
C. Large flowersExplanation
Large flowers are not likely to cause hay fever because they are typically pollinated by insects, not wind. Hay fever is caused by an allergic reaction to pollen, which is usually produced by plants that are wind-pollinated, such as grasses and trees. Insects-pollinated plants, like large flowers, have heavier and stickier pollen that is less likely to become airborne and cause allergies. Therefore, large flowers are not a common trigger for hay fever.Rate this question:

Plant participate in the cycling of carbon dioxide and oxygen on Earth by cellular respiration.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Plants actually participate in the cycling of carbon dioxide and oxygen on Earth through a process called photosynthesis, not cellular respiration. During photosynthesis, plants take in carbon dioxide from the atmosphere and release oxygen as a byproduct. This process is essential for maintaining the balance of gases in the atmosphere and is a major contributor to the production of oxygen on Earth. Cellular respiration, on the other hand, is the process by which plants (and other organisms) use oxygen to convert stored energy into a usable form.Rate this question:

What caused the near elimination of American Chestnut trees in the early 1900's?
- A.
Agricultural Research
- B.
Chestnut Bacteria
- C.
Chestnut Blight
- D.
Tobacco Virus
Correct Answer
C. Chestnut BlightExplanation
The near elimination of American Chestnut trees in the early 1900s was caused by Chestnut Blight. This fungal disease, caused by the pathogen Cryphonectria parasitica, was accidentally introduced to North America through imported Asian chestnut trees. The blight spread rapidly, leading to the death of millions of American Chestnut trees, which were once abundant in forests across the eastern United States. This devastating disease significantly impacted the ecosystem and the timber industry, as the American Chestnut was an important and valuable tree species.Rate this question:
