Questions and Answers

1.

The major source of energy of plants is _________
- A.
  
  Chloroplast
- B.
  
  Chlorophyll
- C.
  
  Sunlight
- D.
  
  Starch
Correct Answer
C. Sunlight

Explanation
Plants obtain energy through the process of photosynthesis, in which they convert sunlight into chemical energy. Sunlight is essential for plants as it provides the energy needed to carry out photosynthesis. Chloroplasts, which contain chlorophyll, are the organelles responsible for capturing sunlight and converting it into chemical energy. While chlorophyll is important for photosynthesis, it is not the major source of energy for plants. Starch is a storage form of energy in plants, but it is derived from the energy produced during photosynthesis. Therefore, the correct answer is sunlight.

2.

Which of the following type of reproduction do plant exhibit?
- A.
  
  Alternation of generations
- B.
  
  Asexual Reproduction
- C.
  
  Sexual Reproduction
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Plants exhibit all of the mentioned types of reproduction. Alternation of generations is a type of reproduction where plants alternate between a haploid gametophyte stage and a diploid sporophyte stage. Asexual reproduction in plants involves the production of offspring without the involvement of gametes, such as through vegetative propagation or fragmentation. Sexual reproduction in plants involves the fusion of male and female gametes to produce offspring with genetic variation. Therefore, plants can reproduce through all of these methods.

3.

Which the following is/are the uses of plants?
- A.
  
  Purifying the atmosphere,
- B.
  
  Medicine
- C.
  
  Food
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Plants have multiple uses, including purifying the atmosphere, providing medicine, and serving as a source of food. They play a crucial role in maintaining the balance of gases in the atmosphere by absorbing carbon dioxide and releasing oxygen through photosynthesis. Many plants also possess medicinal properties and are used in the production of various drugs and treatments. Additionally, plants are a primary source of food for humans and animals, providing essential nutrients and sustenance. Therefore, all of the options mentioned - purifying the atmosphere, medicine, and food - are correct uses of plants.

___________________ is the study of plants
- A.
  
  Botany
- B.
  
  Histopathology
- C.
  
  Hematology
- D.
  
  Biochemistry
Correct Answer
A. Botany

Explanation
Botany is the study of plants, including their structure, growth, reproduction, metabolism, and classification. It involves the exploration and understanding of various aspects of plant life, such as their physiological processes, ecological relationships, and evolutionary history. Botanists study different plant species, their habitats, and interactions with the environment. They also contribute to areas like agriculture, conservation, and medicine by researching plant-based resources and their potential applications.

One of these is a way of looking at the relationships in different groups of plants
- A.
  
  Cladogram
- B.
  
  Aritogram
- C.
  
  Botany
- D.
  
  Anatomy
Correct Answer
A. Cladogram

Explanation
A cladogram is a way of looking at the relationships in different groups of plants. It is a diagram that shows the evolutionary relationships between different species or groups of species. It is used in the field of botany to understand the evolutionary history and relatedness of different plant species. A cladogram represents a branching pattern, with each branch representing a common ancestor and the splitting of lineages over time. It helps scientists classify and organize plants based on their shared characteristics and evolutionary relationships.

6.

The following are classifications of plant except
- A.
  
  Bryophytes
- B.
  
  Xylem
- C.
  
  Thallophytes
- D.
  
  Pteridophytes
Correct Answer
B. Xylem

Explanation
Xylem is not a classification of plants, but rather a type of tissue found in vascular plants. It is responsible for transporting water and nutrients from the roots to the rest of the plant. The other options listed are all classifications of plants. Bryophytes are non-vascular plants, thallophytes are a group of primitive plants including algae and fungi, and pteridophytes are vascular plants that reproduce via spores.

7.

Plants fossils includes the following except
- A.
  
  Roots
- B.
  
  Seeds
- C.
  
  Fruit
- D.
  
  None of the above
Correct Answer
D. None of the above

Explanation
The correct answer is "None of the above" because the question asks for an exception among the listed options, which are roots, seeds, and fruit. Since "None of the above" is not included in the list, it is the correct answer as it does not fall under the category of plant fossils.

8.

Most of the solid material in plant is taken from _____________
- A.
  
  Land
- B.
  
  Lithosphere
- C.
  
  Atmosphere
- D.
  
  Biosphere
Correct Answer
C. AtmospHere

Explanation
Plants primarily obtain their solid material from the atmosphere through the process of photosynthesis. During photosynthesis, plants take in carbon dioxide from the air and convert it into glucose, which is used to build the plant's structure. Therefore, the correct answer is "Atmosphere".

Chlorophyll is a ____________ containing pigment
- A.
  
  Boron
- B.
  
  Potassium
- C.
  
  Magnessium
- D.
  
  Carbon
Correct Answer
C. Magnessium

Explanation
Chlorophyll is a pigment responsible for the green color in plants and algae. It plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy. Magnesium is an essential component of chlorophyll, as it is located at the center of the molecule and helps capture light energy. Without magnesium, chlorophyll cannot function properly, leading to a disruption in photosynthesis and a loss of the green pigment. Therefore, the correct answer is magnesium.

.Plant rely on __________ primarily for support
- A.
  
  Soil
- B.
  
  Chlorophyll
- C.
  
  Pyrenoid
- D.
  
  Flagella
Correct Answer
A. Soil

Explanation
Plants rely on soil primarily for support because the roots of the plants anchor themselves in the soil, providing stability and preventing them from falling over. The soil also provides essential nutrients and water to the plants, which are necessary for their growth and survival. Additionally, the soil acts as a medium for the roots to absorb oxygen, which is crucial for respiration. Therefore, soil is essential for plants to obtain support, nutrients, water, and oxygen, making it the correct answer.
