Quiz 2: cell design
True
A gene is a subunit Of information within a chromosome
Isotonic
A water solution that has the same salt concentration as the cells is said to be
Cell wall
Cellulose
C6H12O6 O2 CO2 H2O Energy
Question 23
Ribosomes
The - are responsible for linking amino acids together
The basic unit of life is the cell
The cell theory teaches that
Meiosis
The division of the nucleus in reproductive cells is called
Semipermeable
The plasma membrane allows some molecular species to enter and excludes others. This is therefore referred to as - membrane
Proteins
The plasma membrane is made chemically of a molecule that has both polar and nonpolar ends and contains - inside its structure
A double layer of phospholipids
The plasma membrane is made up of
High
The relative concentration of water in a hypotonic solution is
When the molecules are insoluble
When is facilitated diffusion necessary
Active transport
When the cell concentrates potassium within, against the natural tendency of matter, it is performing
Osmosis
When water moves freely from a membrane containing a higher concentration to a lower concentration the diffusion is called
They are nonpolar and soluble
Why do O2 and CO2 pass through the plasma membrane
Mitochondrion
Production of needed energy
Ribosomes
Production of protein
It will gain water and may burst
When an animal cell is placed in a hypotonic solution
Dependent on one another
All the organelles within the cell are interrelated and
Centrioles
Form fibers to separate chromosomes evenly
Cell wall
Gives strength to cell
False
It would appear logical that the first cell could have started to function from one organelle having formed by accident
Mitochondria
Organelles that produce energy for the cell and ultimately the body are called
Plasma membrane
Phospholipid and protein
Lysosome
Contain digestive enzymes
Chromosomes
Contain genes for traits
Adenosine diphosphate
The energy molecule ATP is a product of the reactant
The product of ATP decomposition
The energy required for the mechanism of "active transport" comes from
Endoplasmic Reticulum
Tubes serving as transportation channels
Nucleolus
Production of ribosomes
Golgi bodies
Production of secretions
Facilitated diffusion Passive diffusion Active transport Pinocytosis Phagocytosis
Question 15
Plasma membrane
Selective membrane
Plastids
Store food or pigments
Pryuvic acid
Glycolysis ends in the production of
Nucleoli
Ribosomal RNA is produced by
False
Ribosomal RNA is produced in the cytoplasm
