The male sperm cells are contained in pollen grains. The female egg cells are contained in the ovary. Sex among the flowering plants involves two separate but related activities: pollination and fertilization. Pollination is the transfer of pollen from the male organ of a flower to the female organ of a flower. The male organ known as an anther generates the pollen grains containing male genetic material. In most flowers, anthers are located at the tip of a stalk known as a stamen.
Also called Bravais lattice, crystal lattice, space lattice. Crystallography. an arrangement in space of isolated points (lattice points) in a regular pattern, showing the positions of atoms, molecules, or ions in the structure of a crystal. 5. Mathematics.
The structure of the crystal lattice and the strength of it is related to the ions it is composed of. Generally, ions with larger charges will form stronger crystal lattices and so will ions of smaller size.
