In botany, the part of the gynecium that receives pollen during pollination is called stigma.
They are regions on the outer side of the surface of the carpels (the female leaves of the flower), separated from the ovary by style. Its surface is generally papillose, where each papilla is a cell, and moist, two features that facilitate the adherence of pollen. Once in the stigma, the pollen germinates, opening and growing from it a pollen tube through which the nucleus or nuclei that carry out the fertilization of the female gametes move. The tube must penetrate through the stigma and style tissue.
If the prefix endo- is Greek for within, and the "plasm" refers to the body of the cell, you can conclude that: The ER actually helps the attached robosomes make proteins. When these new proteins leave the ER (and they do) they move to another/different organelle.
The fluid content of the dentin tubules varies by depth, with superficial dentin containing the lowest fluid content and deeper dentin, ie, dentin closest to the pulp, containing more fluid. The amount of collagen in dentin decreases from superficial to deep dentin.
