What is the similarity between gymnosperms and angiosperms? a. The phloem of both have companion cellsb. The endosperm is formed before fertilization in bothc. Origin of ovule and seed is similar in bothd. Both have leaves, stem, and roots (2024)
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.
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.
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
seed plants
A seed plant or spermatophyte ( lit. 'seed plant'; from Ancient Greek σπέρματος (spérmatos) 'seed', and φυτόν (phytón) 'plant'), also known as a phanerogam (taxon Phanerogamae) or a phaenogam (taxon Phaenogamae), is any plant that produces seeds.
Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization. Gymnosperms and angiosperms have a life cycle that involves the alternation of generations, and both have a reduced gametophyte stage.
The sieve plates are present in sieve tube members of the angiosperms but it is absent in the sieve cells of gymnosperms.So the major difference between the phloem of angiosperms and gymnosperms is sieve tube.
What do angiosperms and gymnosperms have in common? 1. PRODUCE SEEDS AND POLLEN. Shared derived traits define groups; therefore, the angiosperms and gymnosperms must have a common ancestor.
As vascular plants, both groups contain xylem and phloem. All but the most ancient angiosperms contain conducting tissues known as vessels, while gymnosperms (with the exception of Gnetum) do not.
