1.
Any compund produced by plants:
Correct Answer
B. Plant metabolite
Explanation
Plant metabolites refer to any compound produced by plants. This includes both primary metabolites, which are essential for plant growth and development, and secondary metabolites, which are not directly involved in plant growth but play important roles in defense against herbivores, attraction of pollinators, and other ecological functions. Therefore, the correct answer is "Plant metabolite".
2.
Molecules found in all plant cells and are necessary for the life of the plant.
Correct Answer
B. Primary metabolite
Explanation
Primary metabolites are molecules found in all plant cells and are necessary for the life of the plant. They are involved in essential biological processes such as growth, development, and reproduction. Primary metabolites include carbohydrates, proteins, lipids, and nucleic acids, which are required for basic cellular functions. These metabolites are synthesized through primary metabolic pathways and are essential for the survival and normal functioning of the plant. Secondary metabolites, on the other hand, are not essential for the basic life processes of the plant but often play roles in defense, attraction, or communication.
3.
Molecules that are found only in certain cells and in certain plants.
Correct Answer
C. Secondary metabolite
Explanation
Secondary metabolites are molecules that are found only in certain cells and in certain plants. Unlike primary metabolites, which are essential for the basic functions of growth and development, secondary metabolites are not directly involved in these processes. Instead, they often have specialized functions such as defense against predators, attraction of pollinators, or communication between plants. Secondary metabolites are typically produced in response to specific environmental conditions or stimuli, and their presence in certain cells and plants is a result of their specific biological roles.
4.
They are often synthesized in one part of the plant and then stored in vacuoles in another part of the plant. They are also being discovered almost daily__________
Correct Answer
B. Secondary metabolite
Explanation
Secondary metabolites are often synthesized in one part of the plant and then stored in vacuoles in another part of the plant. These compounds are not essential for the plant's growth and development, but they play important roles in defense against herbivores, attraction of pollinators, and adaptation to the environment. Due to their diverse structures and functions, new secondary metabolites are constantly being discovered in plants.
5.
What are some functions of secondary metabolites?
Correct Answer(s)
A. Used to attract animals to pollinate the plant and to disperse its seeds
B. Protecting the plant from herbivores such as insects
C. Used to derive medicine
Explanation
Secondary metabolites are compounds produced by plants that are not directly involved in their growth and development. They serve various functions, such as attracting animals to pollinate the plant and disperse its seeds. By producing compounds that appeal to animals, plants increase the chances of successful reproduction. Additionally, secondary metabolites can act as a defense mechanism against herbivores, deterring insects from feeding on the plant. These compounds can be toxic or unpalatable to herbivores, protecting the plant from damage. Furthermore, secondary metabolites have medicinal properties and can be used to derive medicines for various purposes. They may possess antimicrobial, anti-inflammatory, or antioxidant properties, making them valuable in traditional and modern medicine.
6.
This major class of secondary metabolites is among the most pharmacologically active compounds (many have dramatic physiological effects on humans) examples are morphine, cocaine, and caffeine.
Correct Answer
A. Alkaloids
Explanation
Alkaloids are a major class of secondary metabolites that are known for their high pharmacological activity. Many alkaloids have strong physiological effects on humans, making them important compounds in medicine. Examples of alkaloids include morphine, cocaine, and caffeine. These compounds are widely studied and used for their therapeutic properties.
7.
Created through the mevalonic acid pathway; they are composed of isoprene units.
Correct Answer
B. Terpenoids
Explanation
Terpenoids are organic compounds that are synthesized through the mevalonic acid pathway and are composed of isoprene units. This means that terpenoids are created by linking together multiple isoprene molecules. Terpenoids are widely found in nature and have various functions, including as pigments, fragrances, and as components of essential oils. Therefore, terpenoids are the correct answer as they fit the given description of being created through the mevalonic acid pathway and composed of isoprene units.
8.
_________ itself is released by some plants during hot weather to form a bluish haze.
Correct Answer
B. Isoprene
Explanation
Isoprene is a compound that is released by some plants during hot weather to form a bluish haze. This compound is a volatile organic compound (VOC) and is emitted by various plant species. Isoprene plays a role in the formation of secondary organic aerosols, which contribute to the bluish haze observed in certain regions.
9.
Created through the shikimic acid pathway; it contains a hydroxyl group attached to an aromatic ring.
Correct Answer
C. pHenolics
Explanation
Phenolics are organic compounds created through the shikimic acid pathway and are characterized by having a hydroxyl group attached to an aromatic ring. Alkaloids are a different class of compounds that typically contain a nitrogen atom and are not created through the shikimic acid pathway. Terpenoids, on the other hand, are derived from isoprene units and do not necessarily have a hydroxyl group attached to an aromatic ring. Therefore, the correct answer is phenolics.
10.
They are modifications of amino acids; they are nitrogenous compounds that are bases.
Correct Answer
A. Alkaloids
Explanation
Alkaloids are organic compounds that contain nitrogen and are derived from amino acids. They are commonly found in plants and have various biological activities. Alkaloids are known for their alkaline properties and are often used for their medicinal properties. They are different from terpenoids and phenolics, which are also secondary metabolites found in plants but do not necessarily contain nitrogen.
11.
There is a sense of urgency because the world's tropical rain forests are being destroyed at an alarming rate. The knowledge of medicinal plants associated with tribal cultures is being lost.
Correct Answer
A. True
Explanation
The statement mentions that the world's tropical rainforests are being destroyed at an alarming rate, and as a result, the knowledge of medicinal plants associated with tribal cultures is being lost. This implies that there is a sense of urgency to address this issue. Therefore, the correct answer is true, indicating that there is indeed a sense of urgency due to the destruction of rainforests and the loss of medicinal plant knowledge.
