A cell without little grains is typically referred to as a "clear cell." In histology, clear cells often indicate a lack of certain cytoplasmic components, such as glycogen or lipid, leading to a transparent appearance under a microscope. This term is commonly used in the context of certain types of tumors or in specific tissues where these cells are found.
The male sex cell from a pollen grain is called a sperm cell. It is responsible for fertilizing the female sex cell (ovule) in plants during the process of pollination.
No, a pollen grain is not a spore. A pollen grain is a male gametophyte produced by seed plants for the purpose of reproduction, while a spore is a reproductive cell that can develop into a new organism without the need for fusion with another cell.
A pollen grain is a mature microspore that consists of two cells (generative cell and tube cell) enclosed within a protective wall. A microspore is a haploid cell produced in the sporangia of seed plants that eventually develops into a pollen grain through the process of microsporogenesis.
The pollen grain that sends a tube down the pistil and unites with the ovule is called a sperm cell. This process is known as fertilization and it leads to the formation of a seed. The sperm cell from the pollen grain fertilizes the egg cell within the ovule, initiating seed development.

A cell without a nucleus is called prokaryotic cell.

The joining of the male nucleus from the pollen grain with the egg cell in the ovule is called fertilization. This process results in the formation of a zygote, which eventually develops into an embryo within the seed.
Prokaryotic
It is called a Eukaryotic cell
a cell that does not contain a nucleus is called a prokaryotic cell, so an organism without a nucleus is called a prokaryote
