A1. CELL STRUCTURES AND FUNCTIONS Done as Cell Poster Project A2. CELL STRUCTURES AND INTERRELATIONSHIPS Prokaryotic and Eukaryotic Cells Procaryotic: - simple (Prehistoric, Procaryotic) - no nucleus or cell parts are evident (has ribosomes) - cytoplasm is “soup like” - evolved early on - have cell walls and membranes - carry on regular life functions - bacteria, blue-green algae - DNA are usually in a ring formation Eukaryotic: - has a distinct nucleus - has membrane bound organelles (mitochondria, lysosomes etc.) - evolved later on than prokaryotes - animal and plant cells Test Yourself, P. 65 #1 – 15, #16 a – d) Study Questions 1. Connect the functions of the following cell organelles: i) Nucleus, Golgi apparatus, Vesicle, Rough E.R. ii) Food vesicle, Golgi apparatus, Lysosome iii) Chloroplast, Mitochondria iv) Ribosome, Polysome, Nuclear pore, Nucleolus 2. How does the Golgi apparatus work? 3. What are the differences between animal and plant cells? (make a table) 4. What are the roles of microtubules and filaments in the cell cytoskeleton, in centrioles, and in flagella? 5. Explain the role of the E.R. including the terms rough, smooth and ribosomes.
