To determine which structure is not present in chloroplasts among the given options (Granum, Stroma, Cristae, Thylakoid), let's analyze each component:

1. **Granum**: This is a stack of thylakoids and is indeed present in chloroplasts. Granum plays a crucial role in the light-dependent reactions of photosynthesis.

2. **Stroma**: This is the fluid-filled space surrounding the thylakoids in chloroplasts, and it is where the Calvin cycle takes place. Thus, stroma is also present in chloroplasts.

3. **Cristae**: These are the inner membrane folds of mitochondria, not chloroplasts. Cristae increase the surface area for chemical reactions, particularly those involved in cellular respiration.

4. **Thylakoid**: These are membrane-bound structures within chloroplasts that contain chlorophyll and where the light-dependent reactions of photosynthesis occur.

### Final Answer
The structure that is not present in chloroplasts is **Cristae**.
