Chapter 1Cells Section Reviews and Chapter Review
1-2 1.) In your own words, write a definition for ribosome, lysosome, and cell wall. • A ribosome is an organelle without a membrane that makes proteins from amino acids. • A lysosome is a special kind of vesicle that contains enzymes to break down worn out organelles. • The cell wall is the outer most layer of plant, algae and fungal cells
1-2 2.) Which of the following are found mainly in animal cells?. • A.) mitochondria • B.) lysosomes • C.) ribosomes • D.) Golgi complex
1-2 3.) What is the definition of a Golgi Complex? What is the function of the endoplasmic reticulum? • The Golgi complex is a system of closed off smooth ER that stores and packages proteins for the cell. • The ER is a system of passageways that moves substances such as lipids and proteins around the cell.
1-2 4.) Making Comparisons: Describe three ways in which a plant cell is different from an animal cell. • A plant cell has a cell wall and chloroplasts while an animal cell does not. • A plant cell usually has a large vacuole instead of the many small lysosomes that would be found an animal cell.
1-2 5.) Applying Concepts: Every cell needs ribosomes. Explain why? • Every cell needs ribosomes because ribosomes make proteins. Most of the organelles of a cell are made of these proteins that are essential for life.
1-2 6.) Predicting consequences: A certain virus attacks the mitochondria of cells. What would happen to a cell if al of its mitochondria were destroyed? • The cell would die due a lack of energy, because the mitochondria are the source of a cells energy.
1-2 7.) Expressing Opinions: Do you think that having chloroplasts gives plant cells an advantage over animal cells? Support your opinion. • Having chloroplasts is definitely an advantage that plants have over animals. Chloroplasts allow plants to produce their own food from water, carbon and sunlight. • Animals need to consume other organisms in order to survive.
1-2 8.) Is this a diagram of a plant cell or animal cell? Explain how you know. • This is an example of an animal cell because there is no cell wall and there are numerous mitochondria.
1-2 9.) What organelle does letter “b” refer to? a • “b” is the… • Golgi complex • “a” is the… • Mitochondria • “c” is the… • nucleus b c
