There are three main types of ovaries in a flower: superior, inferior, and half-inferior.

1. Superior ovary: In a flower with a superior ovary, the ovary is located above the attachment point of the other floral parts (sepals, petals, and stamens). This means that the sepals, petals, and stamens are attached below the ovary. Examples of flowers with superior ovaries include lilies, roses, and apples.

2. Inferior ovary: In a flower with an inferior ovary, the ovary is located below the attachment point of the other floral parts. This means that the sepals, petals, and stamens are attached above the ovary. Examples of flowers with inferior ovaries include cherries, strawberries, and pears.

3. Half-inferior ovary: In a flower with a half-inferior ovary, the ovary is partially below and partially above the attachment point of the other floral parts. This means that the sepals, petals, and stamens are attached at the same level as the ovary. Examples of flowers with half-inferior ovaries include blueberries and cranberries.

Types of Ovary in a Flower

1. Superior Ovary:
- Positioned above the point of attachment of other floral parts (sepals, petals, stamens).
- Ovary is independent of the other parts.
- Example: Rose, Lily

2. Half-Inferior Ovary:
- Partially embedded within the receptacle.
- Half of the ovary is fused to the floral tube, while the other half remains free.
- Example: Apple, Pear

3. Inferior Ovary:
- Completely embedded within the receptacle.
- Sepals, petals, and stamens are attached to the rim of the receptacle, which surrounds the ovary.
- Example: Tomato, Cucumber, Watermelon

4. Syncarpous Ovary:
- Formed by the fusion of two or more carpels.
- May have multiple locules (chambers) or a single locule.

5. Apocarpous Ovary:
- Formed by one carpel that is not fused to other carpels.
- May have multiple locules or a single locule.

6. unilocular Ovary:
- Contains a single locule or cavity.
- Example: Peas, Beans

7. Bilocular Ovary:
- Contains two locules.
- Example: Tomato

8. Trilocular Ovary:
- Contains three locules.
- Example: Lily

9. Multilocular Ovary:
- Contains multiple locules (more than three).
- Example: Rose

10. Placentation:

Placentation refers to the arrangement of ovules within the ovary. Types include:

- Parietal Placentation: Ovules are attached directly to the ovary wall.
- Axile Placentation: Ovules are attached to a central axis or column within the ovary.
- Marginal Placentation: Ovules are attached to a single, marginal ridge on the ovary wall.
