Botany: Bryophyte, Fern, Gymnosperm And Angiosperm Quiz
This quiz accompanies the webquest for my botany students on angiosperms, gymnosperms, moss and ferns.
- 1.
According to evolutionary theory, which plant division evolved first?
- A.
Angiosperm
- B.
Gymnosperm
- C.
Fern
- D.
Moss (Bryophyte)
Correct Answer
D. Moss (BryopHyte)Explanation
The correct answer is Moss (Bryophyte). According to evolutionary theory, mosses (bryophytes) evolved first among the given plant divisions. Bryophytes are non-vascular plants that lack specialized tissues for conducting water and nutrients. They are believed to have evolved around 500 million years ago and were the first plants to colonize land. Angiosperms, gymnosperms, and ferns evolved later in the plant evolutionary timeline.Rate this question:

What characteristic do all angiosperms have in common?
- A.
They contain naked seeds.
- B.
They contain a protected seed within a flower.
- C.
They need water for the sperm to swim to the egg.
- D.
They do not have a vascular system.
Correct Answer
B. They contain a protected seed within a flower.Explanation
All angiosperms have a protected seed within a flower. This is a defining characteristic of angiosperms, which are flowering plants. The flower contains the reproductive structures of the plant, including the ovary where the seeds develop and are protected. This is in contrast to gymnosperms, which have naked seeds that are not enclosed within a protective structure like a flower. The presence of a protected seed within a flower is one of the key features that distinguishes angiosperms from other plant groups.Rate this question:

If the seed has two distinct cotyledons, is this considered a monocot or a dicot?
- A.
Dicot
- B.
Monocot
Correct Answer
A. DicotExplanation
If the seed has two distinct cotyledons, it is considered a dicot. Monocots typically have only one cotyledon, while dicots have two. Therefore, the presence of two cotyledons indicates that the seed belongs to the dicot category.Rate this question:

Which gymnosperm division has the most economically useful species?
- A.
Gnetophytes
- B.
Conifers
- C.
Cycads
- D.
Ginko
Correct Answer
B. ConifersExplanation
Conifers are the gymnosperm division that has the most economically useful species. Conifers include trees such as pine, spruce, fir, and cedar, which are widely used for timber, paper production, and as a source of resin and turpentine. They also provide important products like wood pulp for the paper industry, essential oils, and medicinal compounds. Additionally, conifers are commonly used in landscaping and horticulture due to their aesthetic appeal and ability to adapt to various climates. Therefore, conifers have significant economic value and are widely utilized in various industries.Rate this question:

Pine trees fall into which gymnosperm division?
- A.
Ginko
- B.
Cycads
- C.
Conifers
- D.
Gnetophytes
Correct Answer
C. ConifersExplanation
Conifers is the correct answer because pine trees belong to the division of gymnosperms known as conifers. Conifers are characterized by their needle-like leaves and the production of cones for reproduction. They include a wide range of tree species, such as pines, spruces, firs, and cedars. Ginko, cycads, and gnetophytes are also gymnosperms, but they do not include pine trees.Rate this question:

How does a moss differ from a fern.
- A.
Moss roots grow vertically as well as horizontally. Fern roots only grow horizontally.
- B.
Moss has vascular tissue (xylem and phloem) whereas ferns do not.
- C.
Ferns have vascular tissue (xylem and phloem) whereas moss does not.
- D.
There is no difference between the two- they are actually synonyms.
Correct Answer
C. Ferns have vascular tissue (xylem and pHloem) whereas moss does not.Explanation
The correct answer explains that ferns have vascular tissue, including xylem and phloem, while moss does not have this type of tissue. This difference in vascular tissue is a key distinction between ferns and moss.Rate this question:

Angiosperms are broken down further into two groups: monocots and ______________.
- A.
Diatoms
- B.
Diamonds
- C.
Diagonals
- D.
Dicots
Correct Answer
D. DicotsExplanation
Angiosperms, or flowering plants, are divided into two main groups: monocots and dicots. Monocots have one cotyledon (seed leaf) while dicots have two cotyledons. This division is based on differences in their seed structure, leaf venation, flower parts, and root systems. Dicots include many familiar plants such as roses, sunflowers, and oak trees. Therefore, the correct answer is "Dicots".Rate this question:

Which is older (in terms of evolutionary discent)? Gymnosperms or angiosperms? (choose one)
- A.
Gymnosperms
- B.
Angiosperms
Correct Answer
A. GymnospermsExplanation
Gymnosperms are older in terms of evolutionary descent compared to angiosperms. Gymnosperms are a group of plants that have naked seeds, meaning their seeds are not enclosed in a protective fruit. They are considered to be more primitive and have been around for a longer period of time. Angiosperms, on the other hand, are flowering plants that have seeds enclosed in a fruit. They evolved later in the evolutionary timeline and are considered to be more advanced.Rate this question:

Which division of plants causes horrible symptoms for allergy sufferers?
- A.
Cycads
- B.
Ginkos
- C.
Gnetophytes
- D.
Pinophytes (Conifers)
Correct Answer
D. PinopHytes (Conifers)Explanation
Pinophytes, also known as conifers, are the division of plants that cause horrible symptoms for allergy sufferers. Conifers are known for producing large amounts of pollen, which is a common allergen for many people. When individuals with allergies come into contact with conifer pollen, they may experience symptoms such as sneezing, itching, watery eyes, and nasal congestion. Therefore, conifers are often responsible for triggering allergic reactions in susceptible individuals.Rate this question:
