THE PLANT CELL QUIZ – High School 8A Professor: Andres Lopez SCIENCE GRADE 8 Date: ____________________ Student Name_____________________ ________________________ MAXIMUM MARKS 28 Marks __________/ 28 I. Choose the correct response for the following statements or questions Marks: 10 1. A folded organelle that makes proteins. A) Golgi apparatus B) endoplasmic reticulum C) vacuole D) cytosol 2. Plant cells have a rigid protective one outside the cell membrane that works to maintain cell shape. A) cell membrane B) nucleus C) nucleolus D) cell wall 3. The cells enclosed by this, but it allows communication between the inside & the exterior via: -Pores that regulate ion flow (e.g. Ca++, Na+, K+ & Cl-) - Receptors that sense such chemicals. A) endoplasmic reticulum B) nucleus C) cell membrane D) cell wall 5. It is the watery “soup” of the cell surrounding the organelles. Much cell metabolism occurs in it including: -Glycolysis -Signal transduction between organelles. A) Golgi apparatus B) cytosol C) vacuole D) cytoplasm 6. It has a double membrane. Communication with the cytosol occurs via pores. The DNA is contained in the chromatin. - DNA is the same in all cells. - Cell characteristics are determined by the active DNA. - Chromatin condenses to visible chromosomes at cell division. A) cell membrane B) nucleus C) nucleolus D) cell wall 7. This part of the plant cell is located within the nucleus. - Ribosomes are made here. -After creation, the ribosomes move to the rough endoplamic reticulum where they participate in protein synthesis. A) cell membrane B) nucleus C) nucleolus D) cell wall 8. This is a system as a continuation of the outer nuclear membrane, is a network of membranebound vesicles & tubules. A) Golgi apparatus B) endoplasmic reticulum C) vacuole D) cytoplasm 9. They are found both free and in the cytosol and associated with the rough endoplamic reticulum. -They are the site for the messenger RNA (mRNA) translation into proteins. A) lysosomes B) vacuoles C) chloroplasts D) ribosomes 10. These sections, which lack ribosomes are called transitional elements where transport vesicles form to carry newly made products to the Golgi apparatus. A) rough endoplasmic reticulum B) smooth endoplasmic reticulum C) chloroplasts D) ribosomes True of false Marks: 2 1. Mitochondria break down food particles and release their stored energy. The cell uses this energy to fuel all of its activities. T F 2. The cell plant and the animal plant have the same organelles. T F II. A. Match the correct answer using the letters on the right. Marks: 8 1. Tiny organelles that help make proteins. There are many of these organelles in the cytoplasm . ___ a. ribosomes 2. A large organelle that is easy to see under magnification. It controls the activities of the cell, such as growth. ___ b. Golgi apparatus 3. Membrane-bound organelles that contain a green substance (pigment) called chlorophyll. In a process called photosynthesis. _____ c. mitochondria 4. Found in plant cells but not in animal cells The rigid structure that surrounds the cell membrane It provides the cell with strength and support. Materials pass in or out of the cell through pores in the cell wall.. ____ d. vacuole e. cytoplasm f. chloroplasts 5 . A folded organelle that combines proteins made by the endoplasmic reticulum and delivers them to the rest of the cell and outside the cell . ___ 6. These organelles break down food particles and release their stored energy. The cell uses this energy to fuel all of its activities. They are surrounded by a membrane.___ g. photosynthesis h. nucleus i. cell wall 7. Chlorophyll uses the Sun's energy to cover carbon dioxide and water into sugar (food) and oxygen. ____ 8. A large, sac-like organelle that stores excess food, waste, and other substances . Each is surrounded by a membrane . ____ Label the following organelles. Use the words in sections I and II to do it correctly.
