Depending upon the mode of development, endosperms can be of three types: nuclear, cellular and helobial. The diffferences between nuclear and cellular endosperms are tabulated below.
Nuclear endosperm Cellular endosperm
1. Nuclear divisions are not followed by cell divisions. Each division of nuclei is immediately followed by cell divisions.
2. The nuclear mass is then .pushed to periphery and cell walls are laid. Mostly cell wall formation remains incomplete. Complete cell walls are laid from the very beginning, and a solid cellular mass is obtained.
3. A central vacuole is formed initially which ultimately disappears with a few exceptions. No such vacuole is formed generally
4. Examples include wheat, maize, rice etc. Examples include balsam, datura, petunia etc.
