Persistent nucellus is called as______________and is found in ________...
Explanation:
The persistent nucellus refers to the nucellus that remains persistent and does not degenerate even after fertilization. It is found in certain plant species and serves various functions during seed development.
Function of Persistent Nucellus:
The persistent nucellus performs several important functions during seed development, including:
1. Provision of nutrients: The persistent nucellus acts as a source of nutrients for the developing seed. It provides nourishment to the developing embryo and endosperm.
2. Protection: The persistent nucellus offers protection to the developing embryo by forming a protective layer around it.
3. Perisperm formation: In certain plant species, the persistent nucellus undergoes cellular proliferation and forms a specialized tissue called perisperm. Perisperm is a starchy tissue that surrounds the endosperm and provides nourishment to the developing embryo.
Example:
The persistent nucellus is called perisperm, and it is found in black pepper (Piper nigrum). Black pepper is a flowering vine belonging to the Piperaceae family. The perisperm of black pepper is rich in starch and provides nutrients to the developing embryo. It acts as a storage tissue, similar to endosperm in other plant species.
Conclusion:
In conclusion, the persistent nucellus is referred to as perisperm and is found in black pepper (Piper nigrum). The perisperm serves as a source of nutrients and protection for the developing seed.
