Biology Vocabulary

Prep for high school biology vocabulary

TermDefinition
Cell Membrane a 
boundary 
that
 separates 
the
 cell
 from
 the
 outside
 environment.
Cell Wall The
 cell
 walls 
give
 support
 to
 the
 plant
 cell
 and
 provide 
a
 basic
framework.
Chloroplasts Chloroplasts
 are 
organelles 
that 
produce 
chlorophyll
 that
 works
 as
chemical
 photosynthesis
 to 
provide 
power.
Chromosomes A threadlike linear strand of DNA and associated proteins in the nucleus of animal and plant cells that carries the genes and functions in the transmission of hereditary information.
Cytoplasm a
 semi‐ fluid 
substance 
inside
 the 
membrane.
Endoplasmic Reticulum The 
delivery
 system
 of 
the
 cell.
Golgi Bodies They
 serve 
as
 extensions 
of 
the 
endoplasmic
 reticulum
 system,
 packaging, 
and 
moving
 proteins
 around
 in 
the
 cell.
Mitochondria The 
motors 
that 
fuel 
the 
entire
 cell’s
 production.
Nuclear Membrane Its 
purpose
 is
 to
 protect 
the
 nucleus 
from
 harm
 by
 serving
 as 
a
 double
membrane.
Nucleus The 
nucleus
 is
 an 
organelle
 inside
 the
 cell
 that 
guides 
all
 activity.It
is
the 
most 
important
 part
 of
 the
 eukaryotic cell’s
 existence 
because 
the
nucleus
 contains
 deoxyribonucleic
acid
(DNA)
Ribosomes Ribosomes 
produce 
proteins.
Vacuole A small cavity in the cytoplasm of a cell, bound by a single membrane and containing water, food, or metabolic waste.
Prokaryote Prokaryotes 
only
 have
 a
 membrane 
and
 a
 cell
 wall
 that
 enclose 
the
 rest
 of 
their 
insides,
 including
 cytoplasm.

Eukaryote it
 has
 a
 cytoskeleton
 and
 a 
membrane 
enclosed
 by
 sub‐cellular
organelles.
Mitoses a method of cell division, in which the nucleus divides into daughter nuclei, each containing the same number of chromosomes as the parent nucleus.
Meiosis a type of cell division in which a nucleus divides into four daughter nuclei, each containing half the chromosome number of the parent nucleus.
Monomer molecule of low molecular weight capable of reacting with identical or different molecules of low molecular weight to form a polymer.
Polymer a compound of high molecular weight
Carbohydrates Any of a group of organic compounds that includes sugars, starches, celluloses, and gums
Lipids lipids comprise the fats and other esters with analogous properties and constitute, with proteins and carbohydrates, the chief structural components of living cells.
Proteins any of a large group of nitrogenous compounds of high molecular weight that are essential constituents of all living organisms.
