NEET BIOLOGY

Detailed explanation-1: -Technically, gymnosperms are robust and can survive in a variety of habitats. However, angiosperms have two novel features – fruit and flowers. The fruits aid in dispersing seeds, while the flowers provide protection for the ovule. Hence, angiosperms are considered better than gymnosperms.

Detailed explanation-2: -Answer: Angiosperms are considered more advanced than gymnosperm because of the following reasons: 1) Flowering plants develop more seeds and reach maturity more quickly than gymnosperms. 2) Angiosperms also have more complex and specialised woody tissues.

Detailed explanation-3: -Pteridophytes have poorly developed vascular systems with only xylem tracheids and phloem lacking companion cells while gymnosperms have a better developed vascular systems with both having xylem vessels and tracheids and phloem companion cells.

Detailed explanation-4: -Though they both have sporophyte-dominated life cycles, angiosperms and gymnosperms differ in that angiosperms have flowers, fruit-covered seeds, and double fertilization, while gymnosperms do not have flowers, have “naked” seeds, and do not have double fertilization (more on this later).
