The structures involved in storage excretion are 

Options

A. malpighian tubules
B. corpora adiposa
C. corpora cardiaca
D. uricose glands

Answer

To solve the question regarding the structures involved in storage excretion, we will analyze each option provided and identify which structure is primarily responsible for this function.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the structures involved in storage excretion. We need to identify which of the given options is responsible for this function.

2. **Analyzing the Options**:
- **Option A: Malpighian Tubules**:
- These are excretory structures found in some insects. They are responsible for the removal of waste products and play a role in osmoregulation. They absorb waste and excess water from the hemolymph (insect blood) and transport it to the digestive tract for excretion. Thus, they are involved in storage excretion.

- **Option B: Corpora Adiposa**:
- This structure is found in cockroaches and serves as a fat body. It is primarily involved in energy storage rather than excretion. Therefore, it does not play a role in storage excretion.

- **Option C: Corpora Cardiaca**:
- These structures produce hormones that are important for insect development. They do not have a role in excretion, making them irrelevant to the question.

- **Option D: Uricose Glands**:
- These glands are associated with the male reproductive system and are responsible for storing and discharging uric acid. However, they do not serve as storage structures for excretion in the broader sense, as they are specific to uric acid and not general waste.

3. **Conclusion**: After analyzing all the options, it is clear that the **Malpighian Tubules (Option A)** are the structures involved in storage excretion, as they are responsible for the excretion of waste products and play a role in osmoregulation in insects.

### Final Answer:
The structures involved in storage excretion are **Malpighian Tubules**.
