The Parts of A Cell Standard 7.1a Students know cells function similarly in all living organisms.
Cell Membrane • Every cell has a flexible covering that surrounds it called the cell membrane. • The membrane is semi-permeable. This means some substances are allowed into the cell and some substances CANNOT leave or enter the cell.
Cell Wall • Some cells, like plants and fungi have a rigid cell wall. • Cell walls provide shape, support,and protection for the cell. • Animal cells DO NOT have cell walls.
Cytoplasm • Inside every cell is a thick fluid made mostly of water, called the cytoplasm.
What are Organelles? • Inside cells there are structures with specific jobs called organelles. • Some single celled organisms, like bacteria, DO NOT have organelles
Control center- stores DNA Nucleus Inside Nucleus- makes amino acids Nucleolus Ribosomes Proteins made here Endoplasmic Reticulum (ER) Protein & Lipid production Powerhouse of cell- make energy Mitochondrion PLANTS ONLY- Use light to make energy Chloroplast Golgi Apparatus Processing Factory- makes sorts and ships molecules Made in the Golgi- “bubbles” for transport Vesicles Vacuoles “bubbles” for storage
