उत्तर
| Perisperm | Endosperm | |
| 1. | Perisperm is the remnant of nucellus that persists in the seed after fertilization. | Endosperm is the tissue formed after fertilization that nourishes the developing embryo. |
| 2. | It is maternal in origin, derived from the nucellus of the ovule. | It is triploid (3n) in most angiosperms, formed by the fusion of one male gamete with two polar nuclei (triple fusion). |
| 3. | It is diploid (2n), as it is derived from sporophytic tissue of the parent plant. | It is usually triploid (3n), but may be haploid or diploid in some plants. |
