The fluid inside a cell but outside the cell's nucleus. Most chemical reactions in a cell take place in the _______.
cytoplasm
In biology, the structure in a cell that contains the chromosomes. The _____ has a membrane around it, and is where RNA is made from the DNA in the chromosomes.
nucleus
The _________ is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ______ are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
endoplasmic reticulum (ER)
_______ is the diffusion of solutes through transport proteins in the plasma membrane._________is a type of passive transport. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient
Facilitated diffusion
In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body.
Cell
A ______is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Cell Wall
A _______ is a membrane-bound cell organelle that contains digestive enzymes. ______ are involved with various cell processes. They break down excess or worn-out cell parts.
lysosome
________ have a double membrane structure and use aerobic respiration to generate adenosine triphosphate, which is used throughout the cell as a source of chemical energy.
Mitochondria
________ is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Osmosis
These cells are specialized for communication. on the words A type of cell that receives and sends messages from the body to the brain and back to the body
Nerve Cells
The consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
cell membrane
________ are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process.
Chloroplasts
_______ link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits.
Ribosomes
__________ is the process by which large molecules enter the cell.
Endocytosis
These cells are tightly attached to one another.
Epithelial Cells
A small structure in a cell that is surrounded by a membrane and has a specific function.
Organelle
A ________ is a membrane-bound organelle which is present in plant and fungal cells and some protist, animal, and bacterial cells.
vacuole
A__________ is a membrane that allows only some substances and molecules to pass into or leave the cell. An example of a selectively-permeable membrane is the cell membrane. It allows the passage of only certain types of molecules through diffusion and occasionally by facilitated diffusion
selectively-permeable membrane
_________ the process by which molecules leave the cell.
Exocytosis
These cells are specialized for contraction.
Muscle Cells
Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound vesicles inside the cell before the vesicles are sent to their destination.
Golgi Apparatus
Cells are composed of water, inorganic ions, and carbon-containing (organic) ______.
molecules
_________ is the process by which molecules move from an area of higher concentration to an area of lower concentration.
Diffusion
_____________is defined as movement of a solute from a region of high electrochemical potential on one side of the cell membrane to a region of lower electrochemical potential on the opposite side. At the same time the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy is called what?
Passive transport and Active Transport
Connective tissue is classified into two subtypes: soft and specialized connective tissue. Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body.
