cells

• The cell membrane is a semi-permeable outer covering of cells that controls the entrance and exit of materials in the cell.
• Ribosomes synthesize proteins using instructions from DNA.
• Mitochondria are responsible for producing energy through cellular respiration.
• Osmosis is the diffusion of water molecules across the cell membrane
• The nucleus is the control center of the cell, containing genetic material (DNA) that determines an organism's characteristics.
• Eukaryotic cells have a nucleus, while prokaryotic do not have a nucleus.
• Vacuoles store water, nutrients, or waste products inside the cell.
• Chloroplasts are found only in plant cells and are involved in photosynthesis.
• Endoplasmic reticulum is involved in protein production and transport within the cell.
• Cell walls provide structural support and protect from damage
• Golgi bodies collect and process materials, make and secrete mucus and transport them to the cell membrane
• cytoplasm is the site of chemical reactions and where most of the cell's organelles are found
• cell theory: all living things are made up of cells, cells are the basic unit of life, cells are the building blocks of all living things
