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.
Silicon Lattice. Silicon atoms form covalent bonds and can crystallize into a regular lattice. The illustration below is a simplified sketch; the actual crystal structure of silicon is a diamond lattice. This crystal is called an intrinsic semiconductor and can conduct a small amount of current.olid state electronics arises from the unique properties of silicon and germanium, each of which has four valence electrons and which form crystal lattices in which substituted atoms (dopants) can dramatically change the electrical properties.
