Cell Basics
$200The phrase for life's smallest structural and functional level.
$400This instrument uses lenses to make cells appear larger.
$600An organism made of a single cell is described by this term.
$800This principle states that all living things are made of cells and that new cells come from existing cells.
$1000A bacterium belongs to this cell type, which lacks a membrane-bound nucleus.
Boundaries and Transport
$200This thin, flexible boundary controls what enters and leaves a cell.
$400Particles spreading from an area of higher concentration to lower concentration use this process.
$600The diffusion of water across a selectively permeable membrane has this name.
$800Movement across a membrane that does not require cellular energy is grouped under this term.
$1000A membrane protein uses ATP to move particles against their concentration gradient in this type of transport.
Organelle Jobs
$200This organelle stores most of a eukaryotic cell's DNA and directs many cell activities.
$400This tiny structure assembles amino acids into proteins.
$600This organelle converts energy from food into ATP during cellular respiration.
$800Proteins are modified, sorted, and packaged for transport by this stack of flattened membranes.
$1000Digestive enzymes inside this organelle break down worn-out cell parts and large molecules.
Plant or Animal?
$200This rigid outer layer supports plant cells but is absent from animal cells.
$400Light energy is captured for photosynthesis inside this plant-cell organelle.
$600This large fluid-filled compartment helps a plant cell maintain internal pressure.
$800A cell with chloroplasts, a rigid wall, and one large vacuole is this type.
$1000A cell with centrioles and many small lysosomes, but no chloroplasts or rigid wall, is this type.
Levels of Organization
$200A group of similar cells working together forms this level of organization.
$400Several tissue types working together form this structure, such as the heart.
$600The digestive tract and its supporting organs together make up this level.
$800One individual living thing represents this complete level of biological organization.
$1000The process by which unspecialized cells develop distinct structures and jobs has this name.
Apply Cell Science
$200A muscle cell's many mitochondria help supply large amounts of this usable energy molecule.
$400A wilted plant becomes firm after watering because this pressure rises inside its cells.
$600A red blood cell placed in pure water swells as water enters through this membrane process.
$800A poison that blocks ribosomes would most directly stop production of this type of molecule.
$1000A cell image is 40 millimeters wide while the real cell is 0.04 millimeter wide; this is the image's magnification.
