a group of similar cells that have a similar function
tissue
a living being
organism
a white, tasteless, granular complex
carbohydrate
starch
the female reproductive cell
egg cell
the smallest unit of life that can exist
independently and that makes up all
living things
cell
a type of cellular respiration, not requiring oxygen, in which food is broken down into carbon dioxide and alcohol, with
the release of energy
fermentation
the production of energy through the
conversion of complex molecules into simpler ones (breaking down)
catabolism
the part of the cell that controls all the
cell’s activities
nucleus
the layer of matter that separates the nucleus from the cytoplasm; the nucleus’s skin
nuclear membrane
thin layer of matter of enclosing a cell;
the cell’s skin
cell membrane
a group of atoms that are held together by
covalent or ionic bonds
molecule
a metabolic process in which energy is used to make compounds
and tissues from simple molecules
(building up)
anabolism
the part of a cell’s nucleus that
contains genetic information
chromatin
a complex natural substance that has a globular or fibrous structure, composed
of amino acids
protein
a part of a cell that has a role in
making protein
ribosome
the jellylike substance that surrounds a cell’s nucleus and holds the cell’s other structures
cytoplasm
a structure within a cell that performs a specific function to keep the cell alive
organelle
the process by which a cell nucleus divides
during cell division to form two daughter
nuclei identical to the parent nucleus
mitosis
the chemical process requiring oxygen by which living things
convert food to energy
cellular respiration
the cells produced as a result of cell division, each identical to the
parent cell
daughter cell
the cell undergoing mitosis and cell
division
parent cell
an organic compound of
carbon, oxygen, and hydrogen that is part
of many foods
carbohydrate
the chemical process by which green plants convert water and carbon dioxide
into food and oxygen using energy absorbed from sunlight or other light
photosynthesis
an inherited characteristic
trait
a trait that will appear in an offspring if
one parent contributes it
dominant trait
the study of inherited
characteristics
genetics
a trait that does not appear
when combined with a
dominant trait, and that must
be contributed by both
parents to appear in the
offspring
recessive trait
an organism that, when bred,
always produces the same trait in
its offspring
purebred
an organism that carries both the dominant and
recessive versions of a particular trait
hybrid
an organism that carries both the dominant and recessive versions of a particular trait
a part of the genetic molecule
DNA that determines a
particular trait
gene
