Name ________________________________________ Period _______ Cell Review Answers Parent Signature (2% extra credit on test) I have gone over this study guide with my student for at least 30 minutes. _____________________________ Cell Organelles 1. What is the function of the following organelles? Fill in the chart below. Organelle Mitochondria Nucleus Ribosomes Cytoplasm Endoplasmic Reticulum Cell Wall Cell Membrane Vacuole Chloroplast Lysosomes Function Organelle where food, water, and oxygen go and are used to produce energy for the cell Main control center of the cell, controls activities, where DNA is found Organelle where proteins are made Gel-like fluid that fills the cell and provides some structure Organelle that helps stuff move around the cell, transportation throughout the cell Found only in plant cells, the stiff outer covering that gives the cell structure and support Found in all cells, the outer covering that controls what goes in and out of the cell, protects Used for storage of food, water, waste, etc. Found only in plant cells, where the plant cell actually makes food Usually found in animal cells, gets rid of waste 2. What are the differences between plant and animal cells? (At least 4) 1. 2. 3. 4. 5. Shape. Plant cells usually have straight sides, animal cells usually don’t have straight sides. Plant cells have a cell wall, animal cells do not. Plant cells have chloroplasts, animal cells do not. Plant cells generally have one large vacuole, animal cells generally have several small vacuoles. Plant cells rarely have lysosomes, animal cells usually have them. 3. Label the organelles shown in the pictures below. Label the cells as plant or animal cells. Plant Cell or Animal Cell? Animal Cell Plant Cell or Animal Cell? Plant Cell For pictures of the cells, please see the “Cell Structures” powerpoint on my website. 4. Does a plant cell have mitochondria? Explain why or why not. Yes, plant cells have mitochondria. Plant cells use energy just like animal cells, therefore they have mitochondria. 5. What is the purpose of the chloroplast? Chloroplasts make food in plant cells. The food is then used in the mitochondria to produce energy. Living and Non Living 1. List the 6 characteristics all living things have in common: Made of cells, cells contain DNA, use energy, grow and develop, respond to environment, and reproduce. 2. Explain in detail why a frog is considered living? A frog is living because it has all of the 6 basic characteristics of living things. 3. Explain in detail why a plastic fork is considered non-living? A fork is non-living because it does not have all of the 6 basic characteristics of living things. It may have some of them, but it does not have all 6 and therefore is non-living. 4. What is the difference between living, non-living, and dead? Be detailed in your answer!! Non-living means it never had all 6 of the characteristics. Living means it has all 6. Dead means it used to have all 6 but no longer has all 6 and will never again have all 6. 5. What are the 5 basic needs or requirements for keeping all living organisms alive? Food, water, oxygen, living space, and keeping their internal conditions stable (homeostasis.) 6. Put the following things into the correct category of living, non-living, and dead: Snake Bar of Soap Rain Grapes Germs Chair Redwood Tree Wind Firewood Fallen Leaves Fossil Music Living Snake Grapes Redwood Tree Germs Non-Living Bar of Soap Wind Music Rain Dead Fallen Leaves Fossil (depends on the fossil) Firewood Chair (if it is made of wood) Cell History 1. Draw a brief timeline of this history of cells. Show the main scientists and their contributions IN ORDER. Also label the major invention that allowed scientists to see cells. Microscope Invented Cells Seen (Cork) Cells Seen All animals are (Living Cells) made of cells All plants are made of cells Cells come from other cells 2. Do we know everything there is to know about the cell? Explain. No! There are always new discoveries being made, new and better microscopes being invented, etc. Science is constantly changing and progressing. Osmosis and Diffusion 1. What is the definition of the following? Fill in the chart below. Method of Movement Definition Movement of molecules from a high Diffusion concentration to a low concentration, requiring no energy. Movement of water molecules from a high Osmosis concentration to a low concentration, requiring no energy. Movement of molecules from a low Active Transport concentration to a high concentration, or moving big molecules, requiring energy. Example Air freshener spreading out in a room. Water moving into or out of vegetable cells. Cells moving food molecules from blood stream into the cell. 2. Explain why your skin feels wrinkly after swimming in a lake but tight after swimming in the ocean. Be detailed in your answer!! If you swim in a fresh water lake, the water concentration in the lake is higher than your skin cells, so water moves into your skin cells. In the ocean the water concentration is lower than you akin cells, so water moves out of your skin cells. Levels of Organization 1. Name the 5 levels of organization (starting at the level where it is considered living) in order from least complex to most complex: Atoms→Molecules→Organelles→Cells→ Tissues→ Organ→ Organ System→ Organism 2. Write a definition for each of the following: Tissue: a group of similar cells working together to do a job Epithelial Tissue: forms all coverings and linings of the body Connective Tissue: connects all of the tissues of the body Muscle Tissue: responsible for movement Nerve Tissue: responsible for coordinating all of the body’s activities Organ: two or more tissue types working together to do a job Organ System: two or more organs working together to do a job Organism: an entire living thing capable of carrying out the tasks of a living thing 3. Fill in the table. Organ System Cardiovascular Sys. Respiratory System Nervous System Break down food to a usable form Pump blood to deliver oxygen and nutrients to cells and waste from cells Get oxygen into the body and carbon dioxide out Control and coordinate all of the body’s activities Main Organs in System Mouth, esophagus, stomach, small and large intestine, liver, gall bladder, pancreas Heart, arteries, veins, capillaries Nose, mouth, trachea, lungs, diaphragm Brain, spinal cord, eyes, nerves Which of the basic needs it meets Food, water, homeostasis (waste removal) Food, water, Oxygen, homeostasis, oxygen homeostasis (waste removal) Purpose of System Digestive System All of them! 4. Which Level of Organization are the following items (see question 1 at the top of the page for levels): A Heart Organ Fat Tissue The Brain Organ Endocrine System Organ System A Bird Organism Red Blood Cell Cell A Frog Organism Muscle Cells Tissue (because it is many cells) *Review the following key terms: Atom, Matter, Compound, Mixture, Element, Density, Earth’s Layers
