Question

Monocotyledon and dicotyledons are two groups present in

• A. Angiosperms
• B. Gymnosperms
• C. Pteridophytes
• D. Bryophytes

Answer 1

The correct option is A

Angiosperms

The correct answer is Option A: Angiosperms

Explanation for the correct Option:

1. Angiosperms are a division of plants having 'enclosed seeds,' i.e., plants in which the seeds are enclosed inside fruits.
2. Angiosperms are classified into dicotyledons (dicots) and monocotyledons (monocots).
3. This distinction is mainly based on the number of cotyledons present in the seed's embryo.
4. Dicots have two cotyledons. On the other hand, monocots have only one cotyledon.

Explanation for the incorrect Options:

Option B:

1. The term gymnosperms mean 'naked seeds.' It refers to the production of seeds without fruit.
2. A gymnosperm embryo has two or more seed leaves at maturity, known as cotyledons.
3. Pine and other conifers may have eight cotyledons; some have as many as 18.

Option C:

1. Pteridophytes are the first group of seedless vascular plants with conducting tissue.

Option D:

1. Bryophytes are multicellular plants with eukaryotes' features and are seedless non-vascular plants.
