They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
Cell
Organelle
is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body.
The movement of water molecules across a semipermeable membrane without the input of energy.
osmosis
Tissue is a group of cells or fluid that work together to perform a specific job in the body like cells in an organ like the kidney or heart or blood cells that carry oxygen to and waste materials from the cells in the body.
Tissue
Organ
a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans.
The movement of molecules from a high concentration to a low concentration without the use of energy.
diffusion
The powerhouse of the cell that makes ATP.
Mitochondria
organ system
a biological system consisting of a group of organs that work together to perform one or more functions.
The use of transport molecules and ATP to move molecules from a low solute concentration to a high solute concentration
active transport
A structure that synthesizes proteins in the cell.
Ribosome
organ system
a biological system consisting of a group of organs that work together to perform one or more functions.
Diffusion of molecules from a high concentration to a low concentration with the use of transport proteins, BUT without the use of energy.
facilitated diffusion
The sodium-potassium ATP pump moves three _____ ions out of the cell for every two _____ ions that move into the cell.
sodium; potassium
organism
an individual living thing that carries on the activities of life by means of organs which have separate functions but are dependent on each other
A mode of vesicular transport in which extracellular molecules bind to receptors on the plasma membrane, the plasma membrane sinks in and forms a clathrin-coated vesicle, and the vesicle is taken-up by the cell.
pinocytosis? What is cell-drinking? What is receptor-mediated endocytosis?
