humans and animals. This enzyme is secreted in the mouth ( buccal cavity) and catalyze
the hydrolysis of starch into maltose and dextrin. Immediately the starch

Chloroplasts are cell organelles that are key in the process of photosynthesis.
The chloroplasts have two distinct parts, one of them called the thylakoid containing the chlorophyll, a pigment essential for photosynthesis and the stroma, a liquid part that contains DNA molecules, enzymes, and ribosomes.
<span>Both protexts the organisms' organelles which are inside the cell.
Animal Cell: Cell Membrane
Plant Cell: Cell Wall
Cell
wall is present only in plants, it is not found in all organisms.
Compared to the cell membrane, a cell wall is thick and has a rigid
structure. You can see it in a light microscope, because it is visible.
It serves as the protective cover that surrounds the plasma membrane in a
plant cell. Cell membrane is composed of lipids. Cell walls can be made
up of cellulose or peptidoglycan or chitin.<span> </span></span>
