Chapter 5 Lesson 3 Information Organelles Objectives Identify the nucleus of a cell Describe structures found in the nucleus Explain the structure and functions of ribosomes Discuss how the nucleus directs cell activities Vocabulary Nuclear envelope Pore Nucleolus Ribosome Genome Chromosome Organelles Small structures in the cell Have specific jobs Have bilayer membranes The Nucleus Largest organelle Control center of the cell Surrounded by a membrane called nuclear envelope. The Nuclear Envelope Covers the nucleus Bilayer Has holes called pores Pores allow messages in and out Inside the Nucleus Nucleolus Ball of fibers Makes an information organelle, the ribosome Holds the DNA of the individual DNA Instructions to make proteins and another organism. Complete strand is a genome. A molecule of DNA is a chromosome Gene is a specific sequence of DNA It folds and coils to fit in the nucleus Ribosomes Information organelle Made from RNA and proteins Make proteins Found in the cytoplasm Found on endoplastic reticulum Help control cell activities Putting it Together Create a foldable or a web of the organelles.
