1
a small, membrane-bound sac that functions in cellular storage and transport; its membrane is capable of fusing
with the plasma membrane and the membranes of the endoplasmic reticulum and Golgi apparatus
3
the entire region between the plasma membrane and the nuclear envelope, consisting of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals
4
Nuclear ______- the double-membrane structure that constitutes the outermost portion of the nucleus
5
a cellular structure that carries out protein synthesis
7
a process of passing material out of a cell
8
______ transport- the method of transporting material that requires energy
9
a linkage between adjacent epithelial cells that forms when cadherins in the plasma membrane attach to
intermediate filaments
10
________ cell- a unicellular organism that lacks a nucleus or any other membrane-bound organelle
13
________ transport- a process by which material moves down a concentration gradient (from high to low concentration) using integral membrane proteins
14
a plant cell organelle that carries out photosynthesis
15
the cellular organelles responsible for carrying out cellular respiration, resulting
in the production of ATP, the cell’s main energy-carrying molecule
17
Smooth endoplasmic reticulum initials- the region of the endoplasmic reticulum that has few or no ribosomes on its cytoplasmic surface and synthesizes carbohydrates, lipids, and steroid hormones; detoxifies chemicals like pesticides, preservatives, medications, and environmental pollutants, and stores calcium ions
21
Cell ____- a rigid cell covering made of cellulose in plants, peptidoglycan in bacteria, non-peptidoglycan compounds in
Archaea, and chitin in fungi that protects the cell, provides structural support, and gives shape to the cell
24
The cell organelle that houses the cell’s DNA and directs the synthesis of ribosomes and proteins
26
_______ apparatus- a eukaryotic organelle made up of a series of stacked membranes that sorts, tags, and packages lipids and proteins for distribution
27
______ transport- a method of transporting material that does not require energy
28
Endoplasmic Reticulum initials- a series of interconnected membranous structures within eukaryotic cells that collectively modify proteins and synthesize lipids
