The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
Two kinds of eukaryotes that have cell walls are plant cells and animal cells.

Red Blood Cells (erythrocytes) and White Blood Cells (leucocytes)
Plant cells have a chloroplasts and also have a cell wall while animal cells do not. That is the only difference between the two kinds of cells.
spleen and tonsils
The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.Another answer would be plant cells and animal cells. The plant cell has an organelle called chloroplast and cell walls. Animal cells have neither.
Two basic kinds of lenses are the concave lens and the convex lens.
A basic cell that has the potential to develop into many different kinds of cells is called a stem cell. Stem cells can be found in the umbilical cord blood right after birth.
Lymphocytes are a type of white blood cell. There are two kinds of lymphocytes. These are the T-cells and B-cells.
sperms and egg cells
Red blood cells and white blood cells.
Two kinds of eukaryotes that have cell walls are plant cells and animal cells.
cells that are big cells that are big have a up to 2~3 nucleus
White blood cells and red blood cells.
