Question

What is a flower?

Answer in Brief

Solution

  1. Any blooming plant's (angiosperms') reproductive unit is referred to as a flower. In angiosperms, sexual reproduction occurs in flowers. A modified stem with a condensed axis is what makes up a typical flower.
  2. A flower is composed of four distinct parts: the calyx, corolla, androecium, and the gynoecium. The male and female reproductive organs of a flower are represented by the androgynecium and gynoecium, respectively.
  3. In contrast to unisexual flowers, which only include either gynoecium or androecium, bisexual flowers have both. Normally separate, the corolla and calyx can occasionally unite to form a perianth.
  4. A complete flower is one that has all four floral parts present.
