circulation
reproduction

The structure at the top of a stalk that supports the flower is called _____.
petals
stamen
pistil
receptacle
nectar
receptacle
The organs of reproduction in plants are all contained in the flower.
To determine the correct answer, we need to understand the function of the organs mentioned in the question and how they relate to plants.
1. Digestion: Digestion is the process of breaking down food into simpler substances that can be absorbed and used by an organism. However, plants do not have a specialized organ for digestion like animals do. They perform photosynthesis to produce their own food.
2. Excretion: Excretion is the process of getting rid of waste products from the body. In plants, cellular waste is primarily eliminated through small openings called stomata on the surface of leaves. However, there is no specialized organ for excretion in plants.
3. Circulation: Circulation refers to the movement of fluids within an organism. While plants have a system called vascular tissue that transports water, nutrients, and other substances, it is not considered a circulatory system like that found in animals.
4. Reproduction: Reproduction is the process by which plants produce offspring. In flowering plants, the reproductive organs are contained within the flower. The male reproductive organ is called the stamen, which consists of the filament and the anther. The female reproductive organ is called the pistil, which consists of the stigma, style, and ovary.
Therefore, the correct answer is reproduction, as the organs responsible for reproduction in plants are all contained within the flower.
