2. **Formation of Perisperm**:
- After fertilization, the nucellus can develop into perisperm. This tissue is important for the nourishment of the embryo as it develops.

3. **Location of Perisperm**:
- Perisperm is typically found at the micropilar end of the seed. It often appears as a reddish, papery structure.

4. **Examples of Plants with Perisperm**:
- Perisperm is present in some angiosperms (flowering plants). Notably, it can be found in seeds like beet (Beta vulgaris) and black pepper (Piper nigrum).

5. **Analyzing the Options**:
- The question provides options: beet, black pepper, both 1 and 2, or Lange's sperms.
- Since both beet and black pepper are known to contain perisperm, the correct answer is "both 1 and 2".

6. **Conclusion**:
