Leaf cells contain chloroplasts. Photosynthesis happens in the chloroplasts as they hold vitality from the sun. Chloroplasts contain chlorophyll, which influences leaves to seem green.
The tissues of the leaf in the middle of the epidermal cells, into which gases diffuse from the stomata, are called mesophyll. The mesophyll can be additionally separated into two layers, the palisade layer, and the springy layer, both of which are stuffed with chloroplasts, the production lines of photosynthesis.

In the small intestine, the
pancreas secretes (pancreatic) lipase to digest triglycerides.
The pancreatic lipase causes
lipolysis by acting as ester bond, breaking the bond and releasing the fatty
acid. Lipids (triglycerides) break down into fatty acids, monoglycerides and diglycerides
enabling the duodenum to absorb it.
