Questions and Answers
- 1.
The production of new plants from underground stems is an example of __________ reproduction.
- A.
Sexual
- B.
Zygote
- C.
Two parent
- D.
Asexual
Correct Answer
D. AsexualExplanation
The production of new plants from underground stems is an example of asexual reproduction. In asexual reproduction, new individuals are produced from a single parent without the involvement of gametes or the fusion of genetic material. Underground stems, such as rhizomes or tubers, can give rise to new plants through processes like budding or fragmentation. This type of reproduction allows for rapid multiplication of plants and the production of genetically identical offspring.Rate this question:

Sexual reproduction in plants, as in all organisms, requires__________.
- A.
A male and female.
- B.
Only a male.
- C.
Only a female.
- D.
Only small parts of the plant.
Correct Answer
A. A male and female.Explanation
Sexual reproduction in plants, like in all organisms, requires the presence of both male and female reproductive structures. This is because plants reproduce sexually through the process of pollination, where pollen from the male reproductive structure (stamen) must be transferred to the female reproductive structure (pistil) for fertilization to occur. The male reproductive structure produces pollen containing sperm cells, while the female reproductive structure contains the ovary where the eggs are located. Thus, both male and female structures are necessary for sexual reproduction in plants.Rate this question:

Spores are produced during the __________ stage of a plant's life cycle.
- A.
Gametophyte
- B.
Sporophyte
- C.
Sexual
- D.
None of the above
Correct Answer
B. SporophyteExplanation
During the sporophyte stage of a plant's life cycle, spores are produced. The sporophyte is the diploid phase of the plant's life cycle, where it produces spore-containing structures such as sporangia. Spores are reproductive cells that can develop into new individuals without the need for fertilization. This is in contrast to the gametophyte stage, which is the haploid phase of the life cycle where gametes are produced through sexual reproduction.Rate this question:

What special types of cells are produced during the gametophyte stage of a plant's life cycle?
- A.
Sex cells
- B.
Zygotes
- C.
Spores
- D.
Seed cells
Correct Answer
A. Sex cellsExplanation
During the gametophyte stage of a plant's life cycle, special types of cells called sex cells are produced. These cells, also known as gametes, are responsible for sexual reproduction in plants. They are produced through the process of meiosis, which results in the formation of male and female gametes. These sex cells are essential for fertilization, as they combine to form a zygote, which develops into a new individual. Therefore, sex cells play a crucial role in the reproductive cycle of plants.Rate this question:

- 5.
One difference between sexual reproduction in plants and animals is that in plants, sex cells __________.
- A.
Are called sperm and egg.
- B.
Join in a process called fertilization.
- C.
Unite to form a zygote.
- D.
Are produced in structures made of haploid cells.
Correct Answer
D. Are produced in structures made of haploid cells.Explanation
In plants, sex cells are produced in structures made of haploid cells. This means that the structures where the sex cells are formed, such as the pollen grains in flowers, are made up of cells that only have one set of chromosomes. This is different from animals, where sex cells are typically produced in the gonads, which are made up of diploid cells. This distinction highlights a key difference in the reproductive processes of plants and animals.Rate this question:

- A.
Dull in color with no nectar but a strong scent
- B.
Brightly colored and unscented
- C.
Pale in color and sweetly scented
- D.
Scented like rotting meat
Correct Answer
C. Pale in color and sweetly scentedExplanation
Moths are nocturnal creatures that are active at night. Since they feed on flowers that are open at night, it would make sense for these flowers to be pale in color, as they are more visible in low light conditions. Additionally, the flowers are sweetly scented to attract the moths, as they rely on scent rather than color to locate their food source in the dark. Therefore, the correct answer is that these flowers are pale in color and sweetly scented.Rate this question:

During pollination, pollen grains are transferred from the anther to the __________.
- A.
Pistil
- B.
Ovary
- C.
Stamen
- D.
Sepal
Correct Answer
A. PistilExplanation
During pollination, pollen grains are transferred from the anther to the pistil. The pistil is the female reproductive organ of a flower, consisting of the stigma, style, and ovary. The stigma is the sticky surface at the top of the pistil where pollen grains land and germinate. The pollen grains then travel down the style, a tube-like structure, and reach the ovary. Inside the ovary, fertilization occurs, leading to the development of seeds and fruits. Therefore, the pistil is the correct answer as it is the part of the flower that receives the pollen grains during pollination.Rate this question:

Pollen is produced by the __________.
- A.
Stigma
- B.
Ovary
- C.
Anther
- D.
Style
Correct Answer
C. AntherExplanation
Pollen is produced by the anther, which is the male reproductive part of a flower. The anther contains pollen sacs where pollen grains are formed. These pollen grains are then released from the anther and are transferred to the stigma of the same or another flower for fertilization to occur. The stigma, ovary, and style are parts of the female reproductive system in a flower and are not responsible for producing pollen.Rate this question:

What is the name of the process by which a plant makes its own food?
- A.
Reproduction
- B.
Respiration
- C.
Sunlight
- D.
Photosynthesis
Correct Answer
D. PhotosynthesisExplanation
Photosynthesis is the correct answer because it is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. During this process, plants use chlorophyll, a pigment found in their leaves, to capture sunlight energy and convert it into chemical energy, which is then used to produce glucose. This glucose is the plant's food source, providing energy for growth and development. Therefore, photosynthesis is the name of the process by which a plant makes its own food.Rate this question:
