Difference between Perisperm and Pericarp

Are you curious about the inner workings of plants? Then you’ll want to learn about perisperm and pericarp! These two tissues play crucial roles in the growth and development of plants.

The main difference is that perisperm is a seed storage tissue found in some plants while pericarp is the outer layer of a fruit.

Before we move to the differences, let’s understand what are Perisperm and Pericarp:

  • Perisperm: Perisperm is a tissue found inside the seed of some plants that stores nutrients for the developing plant. It is formed from the endosperm, which is the tissue that provides food for the plant embryo.
  • Pericarp: Pericarp, on the other hand, is the outer layer of a fruit that surrounds the seeds. It is made up of three layers: the exocarp (outer layer), mesocarp (middle layer), and endocarp (inner layer).

Now, let’s move to Perisperm vs Pericarp:

Major differences between Perisperm and Pericarp

Perisperm Pericarp
Perisperm is found inside the seed. Pericarp is found on the outside of the fruit.
Perisperm stores nutrients for the plant. Pericarp protects the seeds.
Perisperm is formed from the endosperm. Pericarp is made up of three layers.
Perisperm is not visible to the naked eye. Pericarp can be seen and touched.
Perisperm is only found in some plants. Pericarp is found in all fruits.


That’s it.

Note that sometimes, the question might also be asked as “distinguish between Perisperm and Pericarp”.

Final words

Perisperm and pericarp are two different parts of plants with different functions. Perisperm stores nutrients inside the seed, while pericarp protects the seeds and is the outer layer of a fruit.

Understanding the differences between these two can help us better understand how plants grow and develop.
