Smallest Unit of Life
CELL
First to use a simple microscope to draw cork cells from dead
plants
ROBERT HOOKE
First person to see and draw
living cells
LEEUWENHOEK
Idea that all living things are made of
cells
CELL THEORY
What new cells come from
EXISTING CELLS
A constant internal environment
maintained by cells
HOMEOSTASIS
This grows faster that the surface area
of a cell
CELL VOLUME
This determines the function of a cell
SHAPE
Surrounds the outside of cells &
controls what enters and leaves
CELL MEMBRANE
The fluid and organelles between the cell membrane
and nuclear membrane
CYTOPLASM
Fluid making up the cytoplasm
CYTOSOL
Control center of the cell where DNA is
located
NUCLEUS
Genetic material of a cell
DNA
The phospholipid heads that attract
water
HYDROPHILIC
Cells lacking a nucleus & no
membrane-bound organelles
PROKARYOTES
Region in bacteria where DNA (single
chromosome)
NUCLEOID
Domain containing ancient bacterial
forms
ARCHAEA
Cell structure that perform a specific job
for a cell
ORGANELLE
Cells that have a nucleus and
membrane-bound organelles
EUKARYOTE
Organisms composed of more
than one cell
MULTICELLULAR
Made of similar cells working
together to do a particular job
TISSUES
Made of organs working together to do a particular job
ORGAN SYSTEM
A double layer of these molecules make up the cell
membrane
PHOSPHOLIPIDS
The tails of phospholipids are
this; means it doesn’t like water
HYDROPHOBIC
The model of phospholipids and embedded proteins
of the cell membrane
FLUID MOSAIC
Proteins embedded in the cell membrane
INTEGRAL PROTEINS
Uncoiled chromosomes in
the nucleus of non-dividing cells
CHROMATIN
Genetic material in the nucleus made
of DNA and protein
CHROMOSOMES
Double layer with pores surrounding
the nucleus
NUCLEAR ENVELOPE
Organelle inside of the nucleus that makes ribosomes
NUCLEOLUS
Openings in the nuclear envelope
NUCLEAR PORES
Made of rRNA and protein and
assembly amino acids into a
polypeptide chain
RIBOSOMES
Long, whip-like structures used by
some cells for movement
FLAGELLA
Site of cellular respiration
MITOCHONDRIA
Unattached ribosomes in the
cytoplasm
FREE RIBOSOMES
Energy molecule used by cells to do
work
ATP
Proteins attached only to one side of the cell membrane
PERIPHERAL PROTEINS
System of membranes and
tubes in the cytoplasm
connecting the nuclear membrane
to the cell membrane
ENDOPLASMIC RETICULUM
ER with ribosomes attached to its
surface
ROUGH ER
System of flattened sacs that modify
and package proteins
GOLGI
Small sacs containing cell
products that can be transported from the cell
VESICLES
Organelle that digests food and worn out cell
parts
LYSOSOMES
Made of microtubules and microfilaments to give support to cells and move
organelles
CYTOSKELETON
Organelle made of microtubules in animal cells that helps form the spindle for cell
division
CENTRIOLES
Short, hair-like structures that help
some cells move
CILIA
Made of cellulose and surrounds the
outside of plant cells
CELL WALL
Organelle that contains pigments
in plant cells
PLASTID
The largest organelle found in plants containing
the cell sap
CENTRAL VACUOLE
ER that makes cholesterol & helps
detoxify poisons
SMOOTH ER
