Most flowering plants can achieve pollination in several dif

Most flowering plants can achieve pollination in several different ways. Those that produce pollen and carpels on the same plant may be self-pollinated, but they may also be cross-pollinated by insects or other pollinators. The cape gooseberry (Physics Peruvians) is able to produce seed whether it is self or cross pollinated. Is one type of pollination better than the other? Based on the data in the graphs provided, approximately how many ovules are found in each gooseberry carpel?

Solution

Self-pollination: Involves transfer of pollen from the stamen to the stigma of the same flower .
Cross-pollination: Involves transfer of pollen from the stamen of one flower to the stigma of another flower.
Cross pollination is better than self pollination as:
1. It produces healthier offspring.

2. Results in formation of numerous seeds.

3. Seeds are most viable and possess high germinating capacity.

4. Results in formation of numerous seeds.

5.Introduce variations at genetic level due to new recombinations thus helping in evolution of new varieties.

6. Increase crop yield.

A seed is a ripened ovule. From the data it seems the ovules will be 240 or more.
