2025 With Questions and 100%
DETAILED answers
, Cells - The building blocks of all living things
Tissues - ANSWER: Groups of cells that are similar in structure and function
Nucleus - ANSWER-Control center of cell; contains DNA necessary for cell
reproduction.
Nuclear Envelope - ANSWER-Encloses the jelly-like fluid nucleoplasm in which other
atomic elements are suspended
Nucleoli - ANSWER- One or more may be present in the nucleus, site of ribosome
assembly
Chromatin - ANSWER: When a cell is not dividing, its DNA is combined with protein and
forms a loose network of bumpy threads called _________.
Chromosomes - ANSWER: When a cell is dividing to form two daughter cells, the
chromatin threads coil and condense to form dense, rod-like bodies called
___________.
Plasma Membrane - ANSWER: A fragile, transparent barrier that contains the cell
contents and separates them from the surrounding environment.
Hydrophobic - ANSWER-The __________ makeup of the membrane interior makes the
plasma membrane relatively impermeable to most water-soluble molecules.
Tight Junctions - ANSWER: Impermeable, bind cells together into leak-proof sheets
Desmosomes - ANSWER: Anchoring junctions that prevent cells from being pulled
apart
Gap junctions - ANSWER: Allow communication between cells
Cytoplasm - The cellular material outside the nucleus, inside the plasma membrane.
The "factory area" of the cell.
Cytosol - ANSWER: Semi-transparent fluid that suspends other elements
Inclusions - ANSWER: Chemical substances such as stored nutrients or cell products.
May or may not be present depending on cell type
Organelles - ANSWER: Metabolic machinery of the cell
Mitochondria - The "powerhouse" organelles that convert the chemical energy stored in
food into compounds that are more convenient for the cell to use
