| A | B |
|---|
| Which organisms do not have a cell wall? | animals |
| Know the characteristics of the plasma membrane. | folded membranes increase surface area for effiency. ER is made up of folded membranes. Ribosomes are sometimes attached to folded membranes |
| Folded membranes serve as an advantage because why? | cell processes can be more efficient, the membranes provide a large surface are, the membranes for interconnected compartments |
| Who concluded that al plants are made of living cells? | Schleiden |
| Who contributed to the cell theory? | Hooke, Schleiden, Schwann |
| All living things are made of what? | cells |
| Know what light microscopes and electron microscopes use to magnify objects. | light microscope= light, electron microscope=electron beam |
| What are the three parts of the cell theory? | (1)All organisms are composed of one or more cells (2)The cell is the basic unit of structure and organization of organisms (3)All cells come from preexisting cells |
| Who was the first scientist who described living cells as seen through a simple microscope? | van Leeuwenhoek |
| What is the advantage of electron microscopes over light microscopes? | higher magnification |
| What kind of cell contains a nucleus? | eukaryotic |
| Know the parts of the chloroplasts. | stroma, grana, plastids, thylakoid membranes |
| The fluid mosaic model decribes what? | phospholipid bilayer (know the parts and which is polar and non-polar) |
| Know what makes up the plasma membrane. | phospholipid bilayer |
| What does cholesterol do for the plasma membrane and what would happen if it were not present? | keeps the tails from sticking together. if there were none the plasma membrane would collapse on in itself |
| Know which parts of the phospholipid bilayer likes and does not like water. | polar head (likes water) fatty acid tails (do not like water) |
| Which structure maintains homeostasis? | plasma membrane |
| Which structure is responsible for chemical reactions? | rough endoplasmic reticulum |
| Cell structures that contain digestive enzymes are what? | lysosomes |
| These are the sites for protein synthesis. | ribosomes |
| These are the small, membrane-bound structures? | organelles |
| The movement of materials into and out of the cell is controlled by what? | plasma membrane |
| An organism with a cell that lacks a true nucleus. | prokaryote |
| In a cell, the breakdown of molecules in order to release energy occurs where? | mitochondria |
| These are short, hairlike projections used for locomotion. | cilia |
| These are the structures in plants that transform light energy into chemical energy. | chloroplasts |
| The network of tiny rods and filaments that forms a framework for the cell is called what? | cytoskeleton |
| The pigment that gives plants their green color is what? | chlorophyll |
| The folded system of membranes that forms a network that forms a network of interconnected compartments inside the cell is called what? | endoplasmic reticulum |
| In a cell, the tangles of long strands of DNA form what? | chromatin |
| The functions of a eukaryotic cell are managed by what? | nucleus |
| A structure outside the plasma membrane in some cells is the what? | cell wall |
