Hint: Plants that have reproductive organs, both female and male, or flowers called monoecious plants. These male and female sections are situated at various plant locations.
Complete Answer:
- Based on the presence and lack of bisexual flowers, plants may be classified as monoecious and dioecious.
- In monoecious species, the flowers are unisex, but both pistillate and staminate flowers are present. Pistillate flowers are female flowers, and the stem flowers are male flowers.
- Marchantia is a genus in the order Marchantiales in the Marchantiaceae family, a group of liverworts. The Marchantia exhibits two-layer separation. An upper photosynthetic layer with a well-defined porous upper epidermis and a lower layer of storage.
- The male cone and female cone are both found in Pinus on the same vine. Pinus belongs to gymnosperms in which all sex organs, but on different branches, are found on the same plant.
- Cycas, like the tropical and subtropical ornamental family Cycadaceae, is a genus of 105 palm species. Their leaves are dark green and circular, with a midrib that differs from those of other family members. Instead of compact cones, the seeds are transported along the edges of adapted leaves arranged in a whorl at the top of the trunk.
- Papaya usually grows from a single stem or trunk, which only branches if it has been damaged or purposefully pruned at low temperatures. At the top part of the stem, the dark green leaves appear, growing in a spiral.
So, the correct answer is Option B, Pinus.
Note: Papayas can be dioecious (on various plants, male and female flowers), monoecious (on the same plant, separate male and female flowers) or have both male and female portions of the flower on the same flower.
