Cell Exam Study Guide

Today's assignment is a study review. Each review question is directly based off of your exam tomorrow. Match the organelle with the description. mitochondria When a cell needs energy, I take in nutrients, break them down, and supply energy to the cell. I can also convert stored energy in the cell to food. vacuole I am a large storage unit in the cell. I am very large in plant cells, and I store water, food and wastes. I help support the plant. When I start to drink due to a lack of water, the plant may wilt. chloroplast I am a food producer for plant cells. I absorb light energy from the sun and use it to convert carbon dioxide and water to sugar and oxygen. I am not found in animal cells. lysosome I act like a digestive system in an animal cell. I contain enzymes that break down wastes and other materials. ribosomes We build proteins in the cell. We can be found in several places in the cell, including on the endoplasmic reticulum (ER). What is found?Put Y if found and N if not found in each type of cell. Make sure the Y or N you type is capitalized. Prokaryote Eukaryote: Animal Cell Eukaryote: Plant Cell ribosome Y Y Y nucleus N Y Y cell membrane Y Y Y golgi apparatus N Y Y endoplasmic reticulum (ER) N Y Y cell wall Y N Y mitochondria N Y Y chloroplast N N Y vacuole N Y Y lysosomes N Y Y An analogy is a comparison of two things that are not related. Match the analogy to the correct organelle. Is like a solar panel because it converts sunlight into energy chloroplast Is like a battery because it creates power (ATP) for the cell mitochondria Is like Mrs. Reigel, because it controls the classroom activities nucleus Is like the classroom door because it controls what can enter and exit the cell cell membrane Is like a trash can because it recycles waste lysosome Is like a locker because it stores things for students vacuole Cyanobacteria are organisms commonly found in streams and ponds as chains of cells. A portion of a chain of cyanobacteria cells is shown in the diagram below. The major parts of a cyanobacteria cell are labeled. Is cyanobacteria a prokaryotic or eukaryotic cell? How can you tell by looking at the diagram? (select 3 true statements) prokaryotic because there is no nucleus Prokaryotic because the DNA is free floating. Prokaryotic because there is no nucleus nor any membrane-bound organelles. eukaryotic because ribosomes are present. Eukaryotic because it has DNA. Eukaryotic because it has a cell membrane. Look at the picture of the plant cell. Identify all structures that are not labeled in the plant cell. Chloroplast- perform photosynthesis and convert sunlight into energy Central vacuole- stores water Ribosomes- make proteins Cell wall-protects the cell and supports the cell structure ER- transport protein Golgi-receives modifies, and ships packages (proteins) The vacuole, which stores water and the cell wall, which protects the cell.
