Question

Gymnosperm and Angiosperm show similarity in
A. Leaves , rhizomes and spore
B. Leaves stems roots and seeds
C. Flat leaves , trunks and naked seeds
D. Lack of vascular tissue and small leaflets
E. Needle like leaves, stems , roots and fleshy fruits

Answer 1

Hint: The two main classes of vascular seed plants are angiosperms and gymnosperms. The largest and most numerous group within the kingdom of Plantae is the Angiosperms, which are flowering plants. Gymnosperms are a smaller, more ancient group consisting of "naked seeds" (seeds not covered by a fruit) growing plants.

Complete Answer:
1. Angiosperm and gymnosperms are diploid sporophytes, the primary plant body.
2. The sporophyte is divided into stems, roots and leaves in both circumstances.
Bundles of 3.Vascular are conjoint, collateral and open.
4. Both gymnosperms and angiosperms present secondary growth.
5.Some angiosperm plants are wind pollinated, Similar to gymnosperms.
6. In both classes, the development of gametophytes is significantly reduced.
7. In both classes, pollination occurs.
8. In both classes, the generation of gametophytes is based on sporophytic generation.
9. In some angiosperms and gymnosperms, anomalous secondary thickening occurs.
In certain gymnosperms, 10.Vessels and companion cells occur.
11.Fertilization in both classes is siphonogamatic (using pollen grains).
12. Megaspore production into female gametophyte occurs in both groups within megasporangium(ovule).
13. Embryo development in both groups has been well established.
14. In both classes, the suspensor is formed during embryo development.
15. In gymnosperms and in many angiosperms, polyembryony is common.
16. Ovules grow into seeds in both groups.
17. The germination of the seed is hypogeal or epigeal.

The correct Answer is option (B)Leaves, roots, stem and seeds.

Note: Their variety is the biggest distinction between angiosperms and gymnosperms. Angiosperm diversity is greater than gymnosperm diversity. Angiosperms adapted to a wide variety of terrestrial habitats have shown to be more diverse. Flowers and fruit production are another aspect of angiosperm.
