Question

Which of the following plants is monoecious?

• A. Carica papaya
• B. Chara
• C. Marchantia polymorpha
• D. Cycas circinalis

Answer 1

The Correct Option is B

To determine which of the given plants is monoecious, we need to understand the concept of monoecious plants.

Definition: A monoecious plant is one that has both male and female reproductive organs on the same individual plant. This allows the plant to self-pollinate or rely on pollinators without needing separate male and female plants.

Now, let's analyze the options:

1. Carica papaya: Papaya is dioecious, meaning it has separate male and female plants. Thus, it is not monoecious.
2. Chara: Chara, a genus of green algae, is known for being monoecious, as it possesses both male and female reproductive structures on the same plant.
3. Marchantia polymorpha: This is a liverwort species that is dioecious, with separate male and female plants.
4. Cycas circinalis: Cycas is also dioecious, meaning that male and female cones are found on separate plants.

After analyzing the options, it's clear that:

The correct answer is Chara because it is monoecious.
