Development of Female Gametophytes: Structure of Ovule

Structure of ovule

The ovule is a crucial structure within the ovary of a flower, and it serves as the site of megasporogenesis and subsequent development of seeds following fertilization.

• Integuments: The integuments are protective layers that surround the ovule. They are typically two in number, known as the inner and outer integuments, and they envelop the central mass of cells called the nucellus.
• Micropyle: The micropyle is a small opening in the integumen…

Development of Seed: Types of Seeds Based on Endosperm Persistence, Advantages of Seeds to Angiosperms

• The seed, the final product of sexual reproduction in angiosperms, represents a fertilized ovule and is enclosed within fruits. Seeds play a crucial role in the continuation of plant species as they contain the embryonic plant and necessary resources for its early growth. A typical seed comprises three main parts: the seed coat (s), cotyledon (s), and an embryo axis.
• The cotyledons are simple structures within the embryo, often thick and swollen due to the st…
