Sexual Reproduction in Plants

A flower that has both androecium (male part) and gynoecium (female part) in the same flower is called a bisexual flower.
Example: Hibiscus

A flower that has only one reproductive whorl (either androecium or gynoecium) is called a unisexual flower.

• If it has only androecium: male flower
• If it has only gynoecium: female flower
  Example: Papaya

A flower that has a stalk called pedicel for support is called a pedicellate flower.

• Sexual reproduction involves the fusion of male and female gametes from two parents to form a diploid zygote.
• A flower is the reproductive structure in plants that produces gametes and enables fertilisation.
• A flower has four whorls: calyx, corolla, androecium (male), and gynoecium (female).
• It includes meiosis for gamete formation and fertilisation, producing genetically different offspring.
• Sexual reproduction occurs in three stages: pre-fertilisation, fertilisation, and post-fertilisation.
