CELL TYPE CYTOPLASMIC FEATURES CELL WALL FEATURES 3-D GEOMETRY
Parenchyma Nucleus
Vacuolated
Mitochondria

Subcategories based on conspicuous cytoplasmic features:
 
Name Conspicuous Feature
Chlorenchyma Abundant chloroplasts
Mucilagenous Cells Compound Carbohydrates (Mucilage)
Water Storage Cell Typically larger than surrounding cells
Tanniferous Cell Tannins in vacuoles
Starch Cell Abundant amyloplasts
Oil Cell Abundant oil
Fat Cell Abundant fat
Idioblasts Calcium oxalate or Calcium carbonate crystals
Aerenchyma Large intercellular spaces, often in regular patterns
 

 Primary cell wall uniformally thin or uniformally thick with primary pit fields.

In secondary xylem:  Uniformly thick, lignified secondary wall with simple pits.  Two subcategories on basis of 3-D geometry (Ray and Axial)
Transverse Isodiametric; 

Rectangular with longest axis in radial (Ray)  or longitudinal (Axial) plane
Radial Isodiametric;

Rectangular with longest axis in radial plane (Ray) or longitudinal (Axial) plane
Tangential Isodiametric 
(Ray);

Rectangular with longest axis in  longitudinal (Axial) plane
