Each lattice point represents the position where one constituent particle of the solid which may be a atom, ion or molecule may exist
It may not be only ion or molecule always
A lattice is a synonym for "frame work" for a crystalline structure
A simple cubic lattice has one atom at each lattice point, so the number of atoms in a simple cubic lattice is equal to the number of lattice points. Each lattice point is associated with one atom, so the number of atoms in a simple cubic lattice is equal to the number of lattice points in the lattice.
Simple reason - It violates the cubic symmetry. To see it from another perspective - Base centered cubic lattice is equivalent to a simple tetragonal lattice. Draw two unit cells adjacent to each other. Then connect the base center points to the corener points which are shared by these two unit cells. Then connect the two base centered point in each unit cell. Now you have a simple tetragonal lattice. Simple tetragonal lattice has one lattice point per unit cell compared to two lattice point per unit cell of base centered lattice. Always the lower lattice point lattice is considered for a given symmetry. Because of symmetry breaking, the symmetry of base centered cubic lattice is same as tetragonal lattice.
A framework or lattice is the structure of crystalline materials. For example, a diamond is a lattice covalent bonded and highly organized carbon atoms lending to its super strength. Similarly salt has lattice pattern, but in this case it is from ionic attraction. Nevertheless the lattice in salt gives it the strength to have an intensely high melting point.
In materials science, a lattice is a regular arrangement of atoms within a crystalline structure. A sub-lattice refers to a smaller, repeating unit within the larger lattice structure, often with its own unique properties or characteristics. Sub-lattices can contribute to the overall properties of the material.
The body-centered cubic system has a lattice point at each of the eight corner points of the unit cell plus one lattice point in the centre. Thus it has a net total of 2 lattice points per unit cell ( 1⁄8 × 8 + 1).The face-centered cubic system has lattice points on the faces of the cube, that each gives exactly one half contribution, in addition to the corner lattice points, giving a total of 4 lattice points per unit cell ( 1⁄8 × 8 from the corners plus  1⁄2 × 6 from the faces).
A lattice point represents a constituent particle in a crystal lattice and when lattice points are joined by straight lines, they bring out the geometry of lattice.
A simple cubic lattice has one atom at each lattice point, so the number of atoms in a simple cubic lattice is equal to the number of lattice points. Each lattice point is associated with one atom, so the number of atoms in a simple cubic lattice is equal to the number of lattice points in the lattice.
A primitive translational vector is the smallest vector that can translate a point in a crystal lattice to a similar point. It defines the repeating unit cells in a crystal lattice and is used to describe the periodicity of the lattice structure.
Lattice points are imaginary points in space about which an atom is located. They denote positions of atoms.Space lattice is an infinite three dimensional array of points in which each any every point has its own identical environment. The totality of all such points is space lattice.Space lattice:it is the regular arrangement of the constituent particles(atoms,ions or molecules) of a crystalline solid in three dimensional space.Lattice points or Lattice sites:They are the positions occupied by the atoms,ions or molecules in crystal lattice.

Primitive unit cells use every lattice point as a unit cell vertex.Non-primitive unit cells, however, contain extra lattice points not at the corners.
A Wigner-Seitz cell is a geometric shape that represents the arrangement of atoms in a crystal lattice. It is a polyhedron that surrounds a lattice point and contains all points that are closer to that point than to any other lattice point. The significance of the Wigner-Seitz cell is that it helps to understand the symmetry and packing of atoms in a crystal structure.
I think it would be a point defect because a vacancy in the lattice structure would allow another atom to take the place of the vacancy.
True.
