14. Know the anatomy of a leaf and chloroplast and how it relates to plant life functions.

Stroma

-Thick fluid within chloroplasts -Contains enzymes involved in synthesis of carbohydrates during photosynthesis. -analogus to mito matrix

Thylakoid

-Third membrane system; suspended in the stroma -flattened sacs -Segregates the stroma from the thylakoid space inside these sacs. -Stacked in some places = grana

Mesophyll

-Tissue on the interior of a leaf -contains chloroplasts

Roots

-Water is absorbed through these and delivered to leaf veins.

Chlorophyll

-green pigment that gives leaves their color -in the thylakoid membrane of chloroplasts

Chloroplasts

-membrane bound organelle -photosynthesis takes place -has an envelope of two membranes surrounding stroma

Stomata

-microscopic pores -carbon dioxide enters the leaf, and oxygen exits

Veins

-use to export sugar to roots and other nonphotosynthetic parts of the plant

Photosynthesis

conversion of light energy to chemical energy
