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. Practice: Identifying cell structures. 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. Plasma membranes contain phospholipids, cholesterol, proteins and carbohydrates that are arrayed in regular, repeating rows to form a highly plastic surface for the cell. Read on to know more. Eukaryotic cells are found in organisms from the domain Eukaryota which includes animals, plants, fungi and protists. The cell structure is defined by the cell membrane, the cytoplasm, and the nucleus.A cell is the smallest unit of life and its structure helps it to work as the basic building block of biology.
