Identify the correct sequential stages of embryo development (embryogeny) starting from the zygote in a dicotyledonous plant:

  1. Zygote → Globular embryo → Proembryo → Heart-shaped embryo → Mature embryo
  2. Zygote → Proembryo → Heart-shaped embryo → Globular embryo → Mature embryo
  3. Zygote → Proembryo → Globular embryo → Heart-shaped embryo → Mature embryo
  4. Zygote → Heart-shaped embryo → Globular embryo → Proembryo → Mature embryo

Correct answer · Option 3

Zygote → Proembryo → Globular embryo → Heart-shaped embryo → Mature embryo

Explanation

The zygote gives rise to the proembryo and subsequently to the globular, heart-shaped, and mature embryo.

Statement II: In non-albuminous seeds such as castor and maize, the endosperm is completely consumed during embryo development. In the light of the above statements, choose the correct answer:→Read the following statements about pollination by water: Statement I: Pollination by water is quite common in flowering plants and occurs in over 200 genera of both dicots and monocots. Statement II: The distribution of some bryophytes and pteridophytes is limited because of the requirement of water for transport of male gametes and fertilisation. Choose the correct option:→In the given three-dimensional cut section of an anther, which structure is responsible for the release of pollen grains upon maturity?→In angiosperms, what is the primary biological significance of the delay in zygote division until a certain amount of endosperm has developed?→
