What are the components of the cell nucleus?
nuclear envelope, nuclear lamina, nucleolus, chromosomes,
nucleoplasm are some of these components
What is the function of the nucleus?
The cell nucleus is commonly found in the center of most cells. It is the
control center of the cell and contains most of the cell's genetic material
encoded within DNA molecules. The nucleus controls a cell's activities
by regulating gene expression.
What is cytoplasm?
the jelly-like substance in which the cell organelles and nucleus are
embedded
nuclear envelope
a porous double membrane barrier that separates the nucleus from the
cytoplasm
nucleoplasm
a jelly-like fluid within the nucleus whose main function is the storage
of the DNA
Nucleoli
spherical bodies containing the genetic materials that are the largest and
prominent components of the cell nucleus
,Chromatin
a bead-like structure found within the chromosomes containing the DNA
and protein
cytoplasm
the jelly-like substance in which the cell organelles and nucleus are
embedded
cytosol
the solution or aqueous part within the cytoplasm in which many
organelles are suspended
cytoplasm organelles
the tiny "organs" or structures within the cytoplasm, which perform
specific functions responsible for the growth, maintenance, and
reproduction of an organism
ribosome
cell organelle responsible for protein synthesis
endoplasmic reticulum
a network of membranes that are important for protein and lipid
synthesis
Golgi complex
a stack of small flat sacs of membranes in the cytoplasm, which prepare
protein and fat molecules
lysosomes
, membrane-bound cell organelles containing digestive enzymes that
disintegrate decayed cell parts and may also destroy viruses and bacteria
Mitochondria
the powerhouse of the cell that helps in ATP production and storage
cell membrane
a thin and flexible membrane surrounding the cells that acts as a barrier
between the intracellular and the extracellular fluids
How does the structure of the cell membrane help control what
enters and leaves the cell?
selective permeability: a specific function of the plasma membrane
which allows passage of selected substances into and out of the cell
hydrophilic
"water-loving"
hydrophobic
"water-repelling," or a substance that gets repealed by water
know how to label the cell
active transport
a process in the cell membrane that requires cellular energy to move
polar and charged solutes in the plasma membrane in opposition to their
electrochemical gradient
gradient
the difference in concentration of substances on one side of a membrane
compared with the other
