Explain type of pollination is found in cleistogamous flower

Text Solution

AI Generated Solution

The correct Answer is:
### Step-by-Step Solution: 1. **Definition of Cleistogamous Flowers**: Cleistogamous flowers are a type of flower that remains closed and does not open. This characteristic prevents the flower from engaging in cross-pollination with other flowers. 2. **Bisexual Nature**: These flowers are typically bisexual, meaning they contain both male (stamens) and female (pistil) reproductive organs within the same flower. 3. **Pollination Process**: Since cleistogamous flowers do not open, they cannot undergo cross-pollination. Instead, the pollination that occurs is self-pollination. This is facilitated by the anthers maturing and bursting open within the closed flower, releasing pollen grains that land on the stigma of the same flower. 4. **Type of Pollination**: The type of pollination found in cleistogamous flowers is known as autogamy. Autogamy refers to the process of self-pollination where pollen from the anther fertilizes the ovule of the same flower. 5. **Advantages of Autogamy**: One of the main advantages of autogamy is that it does not require external pollinating agents (like wind or insects). This ensures a 100% chance of seed setting as the flower can fertilize itself. 6. **Disadvantages of Autogamy**: However, a significant disadvantage is the potential for inbreeding depression. Since the genetic diversity is limited when self-pollination occurs, it can lead to a decrease in the overall quality of the offspring. ### Summary: In summary, cleistogamous flowers undergo a type of pollination called autogamy, which is self-pollination due to their closed structure. While this ensures seed production, it may also lead to inbreeding depression. ---
