Proteins within a cell have many functions, including building cellular structures and serving as enzyme catalysts for cellular chemical reactions that give cells … Plant cell vacuoles are cell structures enclosed by membranes within which there is an aqueous solution made of various substances such as carbohydrates and proteins. In young plant cells, many small vacuoles can be seen; within adult cells, the majority of the internal area of the cell is occupied by a … Ideas about cell structure have changed considerably over the years. A cell is a structural and functional unit of life.Scientist Robert Hook First studied the cell structure in the year 1665 using a self designed microscope. Cells access the information stored in DNA by creating RNA to direct the synthesis of proteins through the process of translation. A cell is the smallest living thing in the human organism, and all living structures in the human body are made of cells. Up Next.
