Answer with explanation:

i) Calyx and Corolla

Calyx

  • Corolla protects the reproductive organs and helps in pollination by attracting pollinators.

  • Bound by the nuclear envelope
  • It contains chromosomes.
  • It is rich in DNA, the genetic material

Nucleolus

  • Very small in size
  • It has no limiting membrane
  • It has no limiting membraneIt does not hold any chromosomes.
  • It is rich in RNA

iii) Dicot and Monocot Seeds

  • Dicot seeds have two distinct cotyledons.

Monocot Seed

  • Monocot seeds are defined as seeds that consist of a single (mono) embryonic leaf or cotyledon.
  • Monocot seeds have a single cotyledon.

iv) Reticulate Venation and Parallel Venation

Reticulate Venation

  • Present in dicot plants.
  • Two Examples are ; mango and hibiscus

Parallel Venation

  • Present in Monocot plants.
  • Two Examples are; banana and bamboo .

v) Androecium and Gynoecium
