Palisade cells are found in the mesophyll of a leaf and their main function is the absorption of light so that photosynthesis can take place. The palisade mesophyll consists of chloroplasts with chlorophyll that absorb the light energy.Continue Reading
The mesophyll layer is made up of the palisade cell and spongy parts. The spongy mesophyll consists of air spaces that aid in the diffusion of gases. The mesophyll region lies directly below the cuticle and the upper epidermis of the leaf.
Some other structures found in a leaf are the lower epidermis, stomata, vascular bundle and guard cells. Each structure plays an important role. For example, guard cells surround stomata and regulate their opening and closing. Stomata are tiny pores that permit gases and other materials to enter into and move out of the leaf. Stomata are found on the leaf's epidermis.Learn more about Molecular Biology & DNA
The function of a leaf on a plant is to store a range of cells that are critical to conducting photosynthesis. Leaves have different layers with different cells, but many of these cells contain structures called chloroplasts, which contain the pigment chlorophyll. Chlorophyll is a pigment that absorbs light from the sun, and most of the chlorophyll in a plant is located in leaves.Full Answer >
Photosynthesis occurs primarily in the mesophyll, which is the middle layer of a leaf. The mesophyll contains cells called chloroplasts, which convert sunlight into a stable chemical energy source the plant can utilize.Full Answer >
The light-independent reactions of photosynthesis take place in the stroma of the chloroplasts. These are the same organelles where the light-dependent reactions of photosynthesis take place, but those happen in a different part of the chloroplast: the thylakoid membrane.Full Answer >
The absorption of proteins, or more precisely amino acids, occurs in the small intestine. Proteins are often huge molecules which must be broken down into amino acids and peptides that are small enough for the small intestine to absorb. After this, the amino acids are sent into the bloodstream.Full Answer >
