Answer:

Angiosperms form covered seeds.
Gymnosperms form naked seeds.
Pteridophytes don't form seeds.
Answer:
Option 3 Pteridophytes is the correct answer.
Explanation:
Pteridophytes were the first plants to have xylem and phloem. Pteridophytes lack flowers and seeds, instead dispersing spores. Pteridophytes are mostly utilized medicinally.
Most plants of the same species in pteridophytes are homosporous. Heterosporous plants generate two types of spores, small and big.
The development of the newborn embryo occurs in female gametophytes; this process is known as seed habit and is the most crucial phase in evolution.
Phanerogams are plants that produce seeds containing embryos and stored nourishment and have specific reproductive systems. This saved food is used during seed germination. Phanerogams are classified into two groups: gymnosperms and angiosperms.
- Gymnosperms are plants in which the ovules are not contained by an ovary wall and are exposed before and after fertilization. The gymnosperm plants that emerge after fertilization are naked and unprotected. Cycas, Pinus, and other gymnosperms are examples.
- Angiosperms are blooming plants that produce ovules and pollen grains in their blooms. In angiosperms, the seeds are encased in the blooms. Angiosperms are a vast category of plants that live in a variety of settings. Eucalyptus and Wolffia are two examples of angiosperms.
Angiosperms are classified into two groups: -
- Dicotyledon seeds include two cotyledons.
- Monocotyledon seeds contain just one cotyledon.
