Chara is a genus of green algae commonly known as stoneworts. These algae are important indicators of freshwater quality and are often used as bioindicators. Chara is a monoecious plant, which means that it has both male and female reproductive organs on the same plant.
Occurrence of Upper Oogonium and Lower Antheridium on the Same Plant
The correct answer to the given question is option C, which states that Chara shows the occurrence of upper oogonium and lower antheridium on the same plant. This means that the female reproductive organ (oogonium) is located above the male reproductive organ (antheridium) on the same plant.
Structure of Chara Plant
Chara plants have a complex structure that consists of a main axis, branches, and whorls of branchlets. The main axis is the central stem of the plant, and it gives rise to lateral branches. The branches, in turn, give rise to whorls of branchlets that are arranged in a spiral pattern around the stem.
Reproductive Organs of Chara Plant
The reproductive organs of Chara are located on the branchlets. The male reproductive organs (antheridia) are small, spherical structures that produce sperm cells. The female reproductive organs (oogonia) are larger, oval-shaped structures that produce eggs.
Occurrence of Monoecious Plant
Chara is a monoecious plant, which means that it has both male and female reproductive organs on the same plant. This is different from dioecious plants, which have male and female reproductive organs on separate plants.
Conclusion
In conclusion, the correct answer to the given question is option C, which states that Chara shows the occurrence of upper oogonium and lower antheridium on the same plant. Chara is a monoecious plant, which means that it has both male and female reproductive organs on the same plant.
