3.2 Cell Organelles KEY CONCEPT Eukaryotic cells share many similarities. 3.2 Cell Organelles Cells have an internal structure. Cytoplasm – The clean gelatinous (jelly) fluid inside the cell. - Chemical reactions take place here. 3.2 Cell Organelles Cells have an internal structure. • The cytoskeleton has many functions. – supports and shapes cell – helps position and transport organelles – provides strength – assists in cell division – aids in cell movement 3.2 Cell Organelles Several organelles are involved in making and processing proteins. • The nucleus stores and protects genetic information (DNA). 3.2 Cell Organelles Cells have an internal structure. Chromatin – granular material within nucleus – DNA bound to protein - Condenses to form chromosome at the time of cell division 3.2 Cell Organelles Several organelles are involved in making and processing proteins. • Many processes occur in the endoplasmic reticulum. – The endoplasmic reticulum aids in the production of proteins and lipids. 3.2 Cell Organelles Several organelles are involved in making and processing proteins. • Many processes occur in the endoplasmic reticulum. • There are two types of endoplasmic reticulum. – rough endoplasmic reticulum – smooth endoplasmic reticulum 3.2 Cell Organelles Several organelles are involved in making and processing proteins. (continued) • The Golgi apparatus modifies, packages, and transports proteins. 3.2 Cell Organelles Several organelles are involved in making and processing proteins. (continued) • Ribosomes link amino acids to form proteins. 3.2 Cell Organelles Several organelles are involved in making and processing proteins. (continued) • Vesicles are membrane-bound sacs that hold materials. 3.2 Cell Organelles Other organelles have various functions. • Mitochondria supply energy to the cell by making ATP. 3.2 Cell Organelles Other organelles have various functions. • Vacuoles are fluid-filled sacs that hold materials like nutrients and wastes. 3.2 Cell Organelles Other organelles have various functions. • Lysosomes contain enzymes to digest material. 3.2 Cell Organelles Other organelles have various functions. • Centrioles are tubes found in the centrosomes. – Centrioles help divide DNA. – Centrioles form cilia and flagella. 3.2 Cell Organelles Cells have an internal structure. Cilia/Flagella – Short/long projections of microtublules. - aid in cell movement 3.2 Cell Organelles Plant cells have cell walls and chloroplasts. • A cell wall provides rigid support. 3.2 Cell Organelles Plant cells have cell walls and chloroplasts. • Chloroplasts convert solar energy to chemical energy (glucose) during the process of photosynthesis.
