A cell membrane is ??? which means that some substances can pass through it while others cannot.
SELECTIVELY PERMEABLE
The process by which molecules tend to move from an area of higher concentration to an area of lower concentration.
DIFFUSION
The diffusion of water molecules through a selectively permeable membrane is called ...
OSMOSIS
The movement of materials through a cell membrane without using energy.
PASSIVE TRANSPORT
The movement of materials through a cell membrane using energy.
ACTIVE TRANSPORT
The process when a cell captures the energy in sunlight and uses it to make food. During the process, plants and some other organisms use energy from the sun to convert carbon dioxide and water into oxygen and sugars including glucose.
PHOTOSYNTHESIS
Chloroplasts in plant cells give plants their green color. This color comes from pigments, colored chemical compounds that absorb light.
PIGMENT
The main pigment found in the chlorplasts of plants.
CHLOROPHYLL
Carbon dioxide enters plants through these small openings on the underside of leaves.
STOMATA
During respiration, cells break down simple food molecules such as glucose and release the energy they contain.
CELLULAR RESPIRATION
Cellular respiration occurs here.
MITOCHONDRIA
The regular sequence of growth and division that cells undergo.
CELL CYCLE
The stage of the cell cycle during which the cell's nucleus divides into two new nuclei with identical chromosomes.
MITOSIS
A rod-shaped cellular structure made of condensed chromatin. It contains DNA.
CHROMOSOME
The part that carries the genetic information which controls inherited characteristics such as eye color and blood type.
DNA
One of the identical rods of a chromosome.
CHROMATID
This "stuff" holds the two strands of chromatids, the identical rods of a chromosome, together.
CENTROMERE
The final stage of the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the two new cells.
CYTOKINESIS
A characteristic that an organism can pass on to its offspring through the genes.
TRAIT
The passing of traits from parents to offspring.
HEREDITY
A cell membrane is ??? which means that some substances can pass through it while others cannot.
SELECTIVELY PERMEABLE
The process by which molecules tend to move from an area of higher concentration to an area of lower concentration.
DIFFUSION
The diffusion of water molecules through a selectively permeable membrane is called ...
OSMOSIS
The movement of materials through a cell membrane without using energy.
PASSIVE TRANSPORT
The movement of materials through a cell membrane using energy.
ACTIVE TRANSPORT
An allele that is masked when a dominant allele is present.
RECESSIVE ALLELE
An organism that has two different alleles for a trait.
HYBRID
The likelihood that a particular event will happen.
PROBABILITY
A chart that shows all the possible combinations of alleles that can result from a genetic cross.
PUNNETT SQUARE
An organism's physical appearance.
PHENOTYPE
An organism's physical appearance.
PHENOTYPE
An organism's genetic makeup, or allele combinations.
GENOTYPE
The process that occurs in sex cells (sperm and egg) by which the number of chromosomes is reduced by half.
MEIOSIS
