The ultrastructure of mesophyll cells of Pinus strobus has been investigated in the spring and winter months. Wall invaginations begin in the early spring and eventually give the cells a lobed appearance. The chloroplasts are of the normal stroma lamella – grana type and completely ring the cells by winter. Lipid globules and electron-dense phenol deposits increase in the winter months.
