What are the properties of a • Well define nucleus.
eukaryotic cell • cells are larger and have more extensive
intracellular anatomy and organization than do
prokaryotes.
• cells bind with deoxyribonucleic acid (DNA) and
are involved in the super coiling of DNA.
• cells have several chromosomes, protein
production or synthesis
. it consists of three components: outer membrane
called plasma membrane, a fluid filling called
cytoplasm, and the intra cellular organs or
organelles
,How do cells communicate with Cells communicate by using hundreds of signal
each other and the environment molecules.
outside the cell -they display plasma membrane-bound signaling
molecules (receptor) that affect the cell itself and
other cells in direct physical contact
-they affect receptor proteins inside the target cell
and the signal molecule has to enter the cell to
bind to them
-they form protein channels (gap juctions) that
directly coordinate the activities of adjacent cells.
responsable for cellular respiration mitocondria
and energy production
they provide sites for cellular protein ribosome
synthesis
is the largest membrane bound nucleus
organelle and is usually found in the
cell center, main function is cell
division and control of genetic
information
, is a small dense structure composed nucleolus
largely of RNA and combine it with
proteins
are saclike structures that originate lysosomes
from the golgi complex and contain
digestive enzymes
specializes in the synthesis and endoplasmic reticulum
transport of the protein and lipid
components of most of the cells
organelles
proteins from the endoplasmic Golgi apparatus or complex
reticulum are processed and
packaged into small membrane
membrane organelles that contain peroxisomes
several oxidative enzymes such as
catalase and urate oxidase. those
enzymes use oxygen to remove
hydrogen in an oxidative reaction
that produces hydrogen peroxide.
it is the gelatinous, semiliquid portion cytosol
of the cytoplasm. functions include:
intermediary metabolism involving
enzymatic biochemical reactions;
ribosomal protein synthesis and
storage of carbohydrates, fat and
secretory vesicles
maintains the cell's shape and cytoskeleton
internal organization
