How are cells discovered?

State the Cell Theory.

They play an important role in synthesizing essential proteins. Ribosomes  Vacuole It stores water and food. It is bigger in plant cells for storage of water.  Mitochondrion It is a double-membrane organelle that is called the powerhouse of the cell.  Golgi apparatus It is the packaging center of the cell. Chloroplast It is the site for photosynthesis.  Cell wall The cell wall is found outside the cell membrane to prevent excessive loss of water.  Plasmodesmat a Enables transport and communication between plant cells.  Centriole Centrioles are cylindrical in shape and they play an important role in organizing the tubules to maintain the shape of the cell.  Lysosome has hydrolytic enzymes used to break down foreign materials such as proteins, nucleic acids, carbohydrates, and lipids Plant Cell vs. Animal Cell
