Biology, Cells, Q2
characteristics of plant cells:
- cell plate and no centrioles in cell division - presence of cell wall plus plasma membrane - large hypertonic vacuole - chloroplasts and plastids
QUOTE five transport mechanisms of the cell:
- facilitated diffusion - passive diffusion - active transport - pinocytosis - phagocytosis
characteristics of an animal cell:
- no cell well, only plasma membrane - no large vacuole, only small ones - no chlorophyll or chloroplasts - cleavage furrow plus centrioles in cell division
all the organelles within a cell are
interrelated and dependent on one another
the plasma membrane allows some molecular species to enter and excludes others.
it is a semipermeable membrane
when an animal cell is placed in a hypotonic solution
it will gain water and may burst
Ribosomal RNA is produced by
nucleoli
mitochondria
organelles that produce energy for the cell and ultimately the body
when water moves freely from a membrane containing a higher concentration to a lower concentration, the diffusion is called
osmosis
phospholipid and protein, selective membrane
plasma membrane
Ribosomal RNA
produced in the cell's nucleus
mitochondrion
production of needed energy
ribosome
production of protein
nucleolus
production of ribosomes
Golgi bodies
production of secretions
the plasma membrane is made chemically of a molecule that has both polar and nonpolar ends and contains
proteins inside its structure
ribosomes
responsible for linking amino acids together
plastics
store foods or pigments
the cell theory teaches that
the basic unit of life is the cell
meiosis
the division of the nucleus in reproductive cells
Adenosine Diphosphate (ADP)
the energy molecule "ATP" is a product of the reactant
the energy required for the mechanism of "active transport" comes from:
the product of ATP decomposition
Why do O2 and CO2 pass through the plasma membrane?
they are nonpolar and soluble
endoplasmic reticulum
tubes serving as transportation channels
active transport
when the cell concentrates potassium within, against the natural tendency of matter, it is performing
when is facilitated diffusion necessary
when the molecules are insoluble
a gene is a subunit of information
within a chromosome
the relative concentration of water in a hypotonic solution is
high
chemical reaction within the mitochondrion
C₆H₁₂O₆ + O₂ -> CO₂ + H₂O+energy
cells are clear evidence of
a Creator with wisdom and foresight
the plasma membrane is made up of
a double layer of phospholipids
isotonic
a water solution that has the same salt concentration as the cells
cellulose and gives strength to the wall
cell wall
lysosomes
contain digestive enzymes
chromosomes
contain genes for traits
glycolysis
ends in the production of pyruvic acid
centrioles
form fibers to separate chromosomes evenly
