Question

What is the similarity between gymnosperms and angiosperms?
a. The phloem of both have companion cells
b. The endosperm is formed before fertilization in both
c. Origin of ovule and seed is similar in both
d. Both have leaves, stem, and roots

Answer 1

Hint: Both have similar basic parts and structure of the plants, thus making it similar in structure except the flowers because the gymnosperm is found to be more simple as compared to the angiosperm that is more advanced like they produce fruit to protect seed.

Complete answer:
Differences and similarities between the angiosperms and the gymnosperms.

Angiosperm	Gymnosperm
Angiosperms are the flowering plants and are also known as the seed-producing plants	Gymnosperms are the non-flowering plants that produce naked seeds.
The angiosperms have plant parts including the leaves, stems, and roots.	The plant parts of gymnosperms are also the same as the angiosperms which include the leaves, stems, and roots.
Angiosperms produce seeds that are enclosed in a covering	Gymnosperms produce naked seeds with no outer covering.
The term angiosperm comes from a Greek word angein meaning “casing” and Sperma meaning “seed”.	The term gymnosperm is derived from a Greek word gymnos meaning “naked “ and Sperma meaning “seed”.
Angiosperms are distinguished from gymnosperms by characters which include flowers, endosperm present inside the seeds, and the formation of fruits that contain seed.	Gymnosperms seeds are developed on the surface of the scales or leaves. They are modified to form cones.
Angiosperms like all vascular plants have a sporophyte-dominant life cycle.	Gymnosperms also have a sporophyte-dominant life cycle as in other vascular plants.

So, the correct answer is ‘Both have stems, leaves, and roots’.

Note: The term angiosperm was coined by Paul Herman in 1690. The early characteristics of seed plants were evident in the fossil of the late Devonian period around 383 million years ago. The ancestors of flowering plants diverged from the gymnosperms in the Triassic period (245-202 million years ago). They diversified early during the early cretaceous period.
