UPDATE
anabolism - ANSWER-Process of building up complex materials (proteins) from
simple materials. Anabolism produces proteins such as hormones and enzymes
that are important to growth of cells. Anabolism occurs in the endoplasmic
reticulum of a cell.
catabolism - ANSWER-Process of breaking down complex materials (foods) to
form simpler substances and release energy
cell membrane - ANSWER-structure surrounding and protecting the cell. It
determines what enters and leaves the cell.
chromosomes - ANSWER-Rod-shaped structures in the nucleus that contain
regions of DNA called genes. There are 46 chromosomes (23 pairs) in every cell
except for the egg and sperm cells, which contain only 23 individual, unpaired
chromosomes.
cytoplasm - ANSWER-All the material that is outside the nucleus and yet
contained within the cell membrane.
DNA - ANSWER-Chemical found within each chromosome. Arranged like a
sequence of recipes in code, it directs the activities of the cell.
, endoplasmic reticulum - ANSWER-Structure (canals) within the cytoplasm. Site
in which large proteins are made from smaller protein pieces. Anabolism takes
place on the ribosomes of the endoplasmic reticulum.
genes - ANSWER-regions of DNA within each chromosome
karyotype - ANSWER-Picture of chromosomes in the nucleus of a cell. The
chromosomes are arranged in numerical order to determine their number and
structure.
metabolism - ANSWER-The total of the chemical process in a cell. It includes
catabolism and anabolism.
mitochondria - ANSWER-Structures in the cytoplasm in which foods are burned
to release energy. Catabolism takes place in mitochondria.
nucleus - ANSWER-Control center of the cell. It contains chromosomes and
directs the activities of the cell.
adipose tissue - ANSWER-Collection of fat cells.
cartilage - ANSWER-flexible connective tissue attached to bones at joints. For
example, it surrounds the trachea and forms part of the external ear and nose.
epithelial cells - ANSWER-skin cells that cover the external body surface and line
the internal surfaces of organs.
