Cells and Tissues Vocabulary Review

A membrane that acts selectively to allow some substances, but not others, to pass

The basic structural, functional, and biological unit of any living organism

Tissue that makes up the structures of the nervous system

The energy-requiring movement of substances across a biological membrane against a concentration gradient

Solutions of equal solute concentration

A transmembrane protein that moves ions across a plasma membrane against their concentration gradient

Active transport process by which membrane-bound secretory vesicles fuse with the plasma membrane and release the vesicle contents into the external environment

A solution with a lower total solute concentration relative to another solution (across a membrane)

The mitosis stage where the daughter chromosomes reach the opposite poles of the cell and reform the nuclei

Process by which a less specialized cell becomes more specialized in order to perform a specific function

A structural and functional part of the cell usually bound within its own membrane. An example is the mitochondria

The division of the cytoplasm of a parent eukaryotic cell into two daughter cells during the late stages of mitosis

A solution with a higher total solute concentration relative to another solution (across a membrane)

Tissue responsible for producing both external and internal movement. Types include skeletal, cardiac, and smooth

An organized structure of DNA and protein found in cells

A class of amphipathic lipids having both a polar and non-polar region, they are a major component of all cell membranes as they can form lipid bilayers

A group of organs that work together to perform a specific task

A collection of cells from the same origin, which together carry out a specific function

A stage of mitosis in a eukaryotic cell in which the chromatin condenses into chromosomes and becomes visible

Passive movement of water molecules across a partially permeable membrane down a concentration gradient

Structures comprising two or more tissues with related functions

The passive movement of molecules from high to low concentration

Active transport process by which cells take in molecules from outside the cell by engulfing it with their plasma membrane

The phase of a cell cycle resulting in nuclear division

Tissue that lines internal and external surfaces

Movement of substances across a biological membrane without energy expenditure

The phase of the cell cycle prior to cell division in which all the DNA in the nucleus is copied

Support tissue that binds other structures together and provides support and protection against damage, infection, or heat loss

A stage of mitosis in which condensed chromosomes align in the middle of the cell
