Questions and Answers
- 1.
The leaf of a fern is called a
- A.
Frond
- B.
Rhizehome
- C.
Fiddlehead
- D.
Biennial
Correct Answer
A. FrondExplanation
The leaf of a fern is called a frond. A frond is a large, compound leaf that is typically divided into smaller leaflets. Ferns are known for their distinctive fronds, which are often feathery or lacy in appearance. The fronds of ferns play a crucial role in photosynthesis, as they are responsible for capturing sunlight and converting it into energy.Rate this question:

Ferns produce spores during
- A.
Germination
- B.
Fertilization
- C.
Sexual reproduction
- D.
Asexual reproduction
Correct Answer
D. Asexual reproductionExplanation
Ferns produce spores during asexual reproduction. Asexual reproduction in ferns occurs through the production of spores, which are tiny cells that can grow into new individuals without the need for fertilization or the involvement of gametes. Spores are produced in specialized structures called sporangia, which are found on the underside of fern fronds. When the spores are released and land in a suitable environment, they can germinate and develop into new fern plants that are genetically identical to the parent plant. This method of reproduction allows ferns to rapidly colonize new areas and is an adaptation to their environment.Rate this question:

Plant tissue that carries food substances down from the plants leaves is called
- A.
Stoma
- B.
Cambium
- C.
Phloem
- D.
Xylem
Correct Answer
C. pHloemExplanation
Phloem is the plant tissue responsible for transporting food substances, such as sugars and other organic compounds, from the leaves to other parts of the plant. This tissue is composed of specialized cells called sieve tube elements and companion cells, which work together to facilitate the movement of nutrients through the plant. Unlike xylem, which transports water and minerals upwards from the roots, phloem transports food substances in a bidirectional manner, allowing for the distribution of nutrients to various parts of the plant. Therefore, phloem is the correct answer in this case.Rate this question:

Which of these structures is not a stem?
- A.
Bulb
- B.
Rhizome
- C.
Frond
- D.
Tuber
Correct Answer
C. FrondExplanation
A frond is not a stem. It is a large, divided leaf that is typically found in ferns and palm trees. Stems are the main structural parts of plants that support leaves, flowers, and fruits. Bulbs, rhizomes, and tubers are all types of stems. Bulbs are underground stems that store food and energy, rhizomes are horizontal stems that grow underground and produce new shoots, and tubers are enlarged, fleshy stems that store nutrients.Rate this question:

Angiosperms produce
- A.
Cones
- B.
Uncovered seeds
- C.
Covered seeds
- D.
Spores
Correct Answer
C. Covered seedsExplanation
Angiosperms are flowering plants that produce covered seeds. The seeds are enclosed within a protective structure called a fruit, which helps in dispersal and protection. This adaptation allows angiosperms to reproduce successfully in a variety of environments. Cones are produced by gymnosperms, not angiosperms. Uncovered seeds are produced by gymnosperms as well, while spores are produced by non-vascular plants like mosses and ferns. Therefore, the correct answer is covered seeds.Rate this question:

The union of the sperm and the egg is called
- A.
Germination
- B.
Transpiration
- C.
Pollination
- D.
Fertilization
Correct Answer
D. FertilizationExplanation
Fertilization is the correct answer because it refers to the process of the union of the sperm and the egg. During fertilization, the sperm penetrates the egg, resulting in the formation of a zygote, which is the first step in the development of a new individual. Germination refers to the process by which a seed grows into a new plant, transpiration is the loss of water vapor from plant tissues, and pollination is the transfer of pollen from the male reproductive organ to the female reproductive organ of a plant.Rate this question:

How many cotyledons does a dicot contain?
- A.
One
- B.
Two
- C.
Three
- D.
Four
Correct Answer
B. TwoExplanation
Dicots, also known as dicotyledons, are a group of flowering plants that have two cotyledons or seed leaves. These cotyledons are the first leaves to emerge from the seed upon germination. They provide nutrients to the developing plant until it can produce its own food through photosynthesis. Therefore, the correct answer is two.Rate this question:

During photosynthesis, carbon dioxide enters the leaf through the
- A.
Stomata
- B.
Rhizoids
- C.
Guard cells
- D.
Rhizomes
Correct Answer
A. StomataExplanation
During photosynthesis, carbon dioxide enters the leaf through the stomata. Stomata are small openings on the surface of leaves that allow for the exchange of gases, including the intake of carbon dioxide and the release of oxygen. These openings are surrounded by specialized cells called guard cells, which regulate the opening and closing of the stomata to control the flow of gases. Rhizoids are root-like structures found in non-vascular plants, while rhizomes are underground stems found in some plants. Therefore, neither rhizoids nor rhizomes are involved in the entry of carbon dioxide during photosynthesis.Rate this question:

Auxins are
- A.
Enzymes
- B.
Sugars
- C.
Hormones
- D.
Fruits
Correct Answer
C. HormonesExplanation
Auxins are a type of plant hormones. They play a crucial role in various plant growth and development processes such as cell elongation, root formation, and fruit development. They are primarily synthesized in the apical meristems of the plant and then transported to other parts, where they regulate various physiological responses. Therefore, the correct answer is hormones.Rate this question:
