Monoecious plant of Chara shows occurrence of

  1. upper antheridium and lower oogonium on the same plant
  2. upper oogonium and lower antheridium on the same plant
  3. antheridiophore and archegoniophore on the same plant
  4. stamen and carpel on the same plant.

Answer

(2) upper oogonium and lower antheridium on the same plant

Solution

In monoecious Chara, the sex organs develop at the nodes of the same plant: the oogonium (female sex organ, nucule) lies above and the antheridium (male sex organ, globule) lies below it (see the figure of Chara in NCERT, Plant Kingdom).

∵ Antheridiophores and archegoniophores occur in Marchantia and stamens and carpels in flowering plants, options (3) and (4) do not apply to an alga.

∴ Chara shows upper oogonium and lower antheridium on the same plant.
