The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Cross section of a leaf, showing the anatomical features important to the study of photosynthesis: stoma, guard cell, mesophyll cells, and vein.

Within the plant cells (usually leaf cells), the cytoplasm contains organelles called chloroplasts where photosynthesis takes place. Each chloroplast contains stacks of struct â¦ ures called thylakoids, which contain the chlorophyll.+ 4 others found this useful.
