Observe the diagram and answer the questions: Label the parts 1 – 4.

1. Ovule: Ovule contains female reproductive cells egg. In the ovary, there can be one too many ovules. Ovules become seed after fertilization. This is the place where the fusion of male and female gametes occurs. 2. Septum: It divides the ovary into two locules. 3. Ovary: Present at the bottom of the pistil. It contains ovules. 4. Receptacle: Also called the thalamus. It is the green color part from which sepal grows.

Observe the diagram and answer the question. State the role of each part.

Ovule: Ovules are the structure located inside the ovary that forms the seeds of flowering plants. Style: A structure found within the flower. It is a long, slender stalk that connects the stigma and the ovary. Ovary: It is the part of the female reproductive organ of the flower. Thalamus: This part found neat the stalk of the flower. It is a modified stem that supplies nutrients to the flower.
