Name: Date: July 07, 2022 Class: SECTIO N 4- 4 REVIEW U NIQUE F EATURES OF P LANT C ELLS VOCABULARY REVIEW Define the following terms. 1. cell wall - a hard coating of inorganic matter that encircles some plant and other creature cells 2. plastid - a significant double-membrane cell with pigments needed for photosynthesis that is mostly found in plant and algae cells. 3. thylakoids - compartments inside cyanobacteria and chloroplasts that are membrane-bound. They serve as the location of the photosynthetic reactions that are light-dependent. 4. chlorophyll - the naturally occurring substance that gives green plants their color. As plants go through the process of photosynthesis, it aids in their ability to absorb solar energy. 5. central vacuole - a cell organelle that is present in plant cells. The largest organelle in the cell is frequently this one. It serves as a container for goods and garbage and is surrounded by a membrane. MULTIPLE CHOICE Write the correct letter in the blank. B 1. Which of the following organelles is found in plant cells but not in animal cells? a. nucleus b. chloroplast c. mitochondrion d. Golgi apparatus B 2. The end products of photosynthesis include a. carbon dioxide and water. b. sugars. c. carbon dioxide and oxygen. d. oxygen and water. A 3. A cell that contains a cell wall, chloroplasts, and a central vacuole is a a. plant cell. b. animal cell. c. prokaryotic cell. d. bacterial cell. C 4. A central vacuole forms from a. chloroplasts. b. fusion of amyloplasts. c. the fusion of smaller vacuoles. d. the products of photosynthesis. C 5. Thylakoids are located a. between the two membranes of a chloroplast. Modern Biology Study Guide 25 Name Class SHORT ANSWER Answer the questions in the space provided. b. outside the outer membrane of a chloroplast. c. inside the inner membrane of a chloroplast. d. in chromoplasts. 26 Section 4-26 Date Name: Date: July 07, 2022 Class: SECTIO N 4- 4 REVIEW 1. How are secondary cell walls different from primary cell walls? Although the secondary cell wall is exceedingly strong and can no longer expand, the primary cell wall grows in one direction. 2. What are plant cell walls made of? Cellulose and enzymes. What is the function of cell walls? Support and protect the plant. 3. What is the appearance of a plant cell when water is plentiful? Thicker than usual 4. Critical Thinking Bacteria have a region called a nucleoid, in which their genetic material is located. Why, then, are bacteria classified as prokaryotes? They are categorized as prokaryotes because they lack a nucleus and organelles that are attached to membranes.
