Plant Biology Questions and Answers
- 1.
Choose two of the following that are found only in plant cells.
- A.
Central vacuole
- B.
Nucleus
- C.
Cytoplasm
- D.
Chloroplast
Correct Answer(s)
A. Central vacuole
D. ChloroplastExplanation
In plant cells, certain structures are exclusive and crucial for their function, including the central vacuole and chloroplasts. The central vacuole is a large vacuole that holds water and maintains internal pressure to support the plant’s structure. Chloroplasts are unique to plant cells and are essential for photosynthesis; they contain chlorophyll and convert solar energy into chemical energy, thereby feeding the plant. In contrast, both the nucleus and cytoplasm are common to all eukaryotic cells, not just plant cells. Thus, for a quiz question asking which components are found only in plant cells, the correct answers would be the central vacuole and chloroplasts, highlighting their unique roles in plant physiology and survival.Rate this question:

A ____________is the necessity for the plant cell to have a fixed shape.
Correct Answer(s)
cell wallExplanation
The cell wall is necessary for the plant cell to have a fixed shape. The cell wall is a rigid structure that surrounds the cell membrane and provides support and protection to the cell. It helps to maintain the shape of the cell and prevents it from collapsing or becoming distorted. Without a cell wall, the plant cell would be unable to maintain its shape and would be more susceptible to damage.Rate this question:

A __________ is used to focus the image of the specimen sharply.
- A.
Coarse focus knob
- B.
Fine focus knob
- C.
Arm
- D.
Eyepiece
Correct Answer
B. Fine focus knobExplanation
The fine focus knob is used to focus the image of the specimen sharply. This knob allows for precise adjustments to the focus, allowing the user to bring the specimen into clear view. The coarse focus knob, on the other hand, is used for initial focusing and larger adjustments. The arm is a part of the microscope that supports the body tube and stage, while the eyepiece is the lens through which the user looks to observe the specimen.Rate this question:

Choose those who are multicellular organisms.
- A.
Hydra
- B.
Cat
- C.
Euglena
- D.
Human
- E.
Yeast
Correct Answer(s)
A. Hydra
B. Cat
D. HumanExplanation
The correct answer includes Hydra, Cat, and Human because they are all multicellular organisms. Multicellular organisms are composed of multiple cells that work together to form tissues, organs, and organ systems. Hydra is a simple multicellular organism belonging to the phylum Cnidaria. Cats and humans are both complex multicellular organisms belonging to the animal kingdom. They have specialized cells, tissues, and organ systems that enable them to carry out various functions necessary for survival. Euglena and Yeast, on the other hand, are unicellular organisms and do not fit the criteria of being multicellular.Rate this question:

Minerals absorbed by root move to the leaf through?
- A.
Xylem
- B.
Phloem
- C.
Sieve tubes
- D.
None of the above
Correct Answer
A. XylemExplanation
The xylem is the vascular tissue responsible for transporting water and minerals from the roots to the leaves in plants. It consists of a series of interconnected tubes that form a network throughout the plant. The movement of water and minerals in the xylem is driven by transpiration, which is the process of water loss from the leaves. Therefore, the correct answer is xylem as it is the pathway through which minerals absorbed by the roots are transported to the leaves.Rate this question:

Greatest producers of organic matter are:
- A.
Crop Plants
- B.
Forests
- C.
Plants of the land
- D.
Phytoplankton of oceans.
Correct Answer
D. pHytoplankton of oceans.Explanation
Phytoplankton of oceans are the greatest producers of organic matter because they are microscopic plants that perform photosynthesis in large quantities. They are found in abundance in the oceans and are responsible for producing a significant amount of oxygen and organic compounds through photosynthesis. This makes them a crucial component of the marine food chain and a major contributor to the overall production of organic matter in the world's ecosystems.Rate this question:

Twining of tendrils is due to:
- A.
Thigmotropism
- B.
Seismonasty
- C.
Heliotropism
- D.
Diageotropism
Correct Answer
A. ThigmotropismExplanation
The tropic movement in response to the stimulus of contact is thigmotropism e.g. coiling of tendrils , haustoria in Cuscuta.Rate this question:

Which of the following is used to determine the rate of transpiration in plants?
- A.
Auxanometer
- B.
Poromeer/hygrometer
- C.
Potometers
- D.
Tensiometer/barometer
Correct Answer
C. PotometersExplanation
Potometers are used to determine the rate of transpiration in plants. A potometer is a device that measures the rate of water uptake by a plant. It consists of a glass tube attached to the stem of a plant, with a graduated scale to measure the movement of water. As water is transpired through the leaves, it creates a negative pressure or tension in the plant, which causes water to be pulled up through the stem. By measuring the movement of water in the potometer, the rate of transpiration can be determined.Rate this question:

Maximum solar energy is trapped by:
- A.
 Planting trees
- B.
Cultivating crops
- C.
Growing algae in tanks
- D.
Growing grasses.
Correct Answer
C. Growing algae in tanksExplanation
Growing algae in tanks is the correct answer because algae have a high photosynthetic efficiency, meaning they can convert a large amount of sunlight into energy through photosynthesis. Algae also have a fast growth rate and can be easily cultivated in controlled environments like tanks, allowing for maximum solar energy capture. Additionally, algae can be used to produce biofuels and other valuable products, making them a sustainable and efficient option for trapping solar energy.Rate this question:

Which one of the following elements is almost inessential for plants?
- A.
Ca
- B.
Na
- C.
Mo
- D.
Zn
Correct Answer
B. NaExplanation
Zn is essential for the synthesis of tryptophan amino acid. Ca is the part of middle lamella, it stabilizes the structure of chromosomes. Mo is responsible for nodulation in legumes. It is a part of nitrate reductase enzyme which helps in nitrogen fixation.Rate this question:
