waste removal will come to a stop. His blood flow aids in removing waste products with needed products to maintain homeostasis. Carbon dioxide is a waster product that needs to be excreted. C. Which intracellular organelles have membranes as part of their structure? All intracellular organelles have membranes as part of their structure except ribosomes. How would the breakdown of the membranes of these structures affect the function of Joseph’s heart cells? The breakdown of the membranes of these structures

70S (small) ribosomes The nucleoid is naked DNA No mitochondria Cell parts The cell parts float in the cytoplasm Under 10 micrometers in diameter 80S (large) ribosomes True nucleus contains DNA Mitocondria Organelles in discrete membranes Internal membranes enclose organelles 10-15µm in diameter 2. What is the literal meaning of the term eukaryote? The term ‘eukaryote’ means “true nucleus” because it has a nucleus not a nucleoid like the prokaryotes. 3. What was Robert Brown’s role

size. Resolution is a measure of the clarity of the image; it is the minimum distance two points can be separated and still be distinguished as two points. 2. The development of electron microscopes has further opened our window on the cell and its organelles. What is considered a major disadvantage of electron microscopes? The methods used to prepare the specimen kill the cells. 3. Study the electron micrographs in your text. Describe the different types of images obtained from: scanning electron microscopy

outer surface‚ separating the cell’s internal environment (inside the cell) from its external environment (outside the cell) cytoplasm- consists of all the cellular contents between the plasma membrane and the nucleus. nucleus- is the largest organelle of a cell. The nucleus acts as the control center for a cell because it contains the genes‚ which control cellular structure and most cellular activities The cell is the basic‚ living‚ structural and functional unit of the body. 1.

Chloroplasts are organelles present in plant cells and some eukaryotic organisms. Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids. The chloroplasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into

Short answer questions – generally complex by their nature and require knowledge and integration of several different concepts 1. Explain what are the end goals of reproductive cloning and therapeutic cloning. Outline the steps both procedures share and the step(s) specific for each procedure. • Reproductive Cloning- Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell
