Describe the characteristics of an ovary which would give rise to the multiple fruit and give an example of the fruit type
An ovary that gives rise to a multiple fruit is one that contains several individual flowers that are all clustered together, with their ovaries fused into a single structure. This results in a fruit that is made up of multiple, separate, but closely grouped "fruitlets". The fruit type resulting from this is known as an aggregate fruit. Each fruitlet may contain its own seed or seeds.
An example of an aggregate fruit is the raspberry. Each raspberry is made up of many small fruitlets that are all attached at the base of the fruit. Each fruitlet contains a tiny seed, and they all combine to create the characteristic juicy berry that we enjoy. Another example would be the blackberry, which is similar in structure to the raspberry.
The characteristics of an ovary that give rise to multiple fruits include:
1. Compound ovary structure: The ovary is made up of multiple carpels, which are the female reproductive parts of a flower. Each carpel contains one or more ovules.
2. Fusion of carpels: The carpels may be fused together, forming a single ovary with multiple chambers or compartments. Each chamber contains one or more ovules.
3. Formation of multiple seeds: Each ovule within the ovary develops into a seed, resulting in multiple seeds within the fruit.
An example of a fruit type formed by a multiple ovary is the pineapple. The pineapple fruit is derived from an ovary with multiple carpels fused together. Each "eye" on the pineapple corresponds to a separate carpel and contains a separate ovule, which develops into a seed. However, most commercial pineapples are seedless due to cultivation techniques.
