Cells
Organisms that can make their own food.
What is an autotroph?
Organisms that cannot make their own food.
What are heterotrophs?
When molecules move from an area of HIGH concentration to an area of LOW concentration
What is Diffusion?
Organisms with cells with a nucleus and membrane bound organelles
What are Eukaryotes?
XX and XY
The basic unit of structure and function in an organism
What is a cell?
Single-celled organisms, composed of only one cell
What is unicellular?
Some substances can pass through cell membrane while others cannot.
What is selectively permeable?
Organisms that lack a nucleus
Passing of traits from parents to offspring
What is Heredity?
The ability to make things look larger
What is Magnification?
The ability to see details and clear images
What is Resolution?
Movement of materials through the cell membrane USING energy
What is Active Transport
Movement of materials through the cell membrane WITHOUT using energy.
What is Passive Transport?
Physical appearance, visible traits versus genetic makeup
Phenotype versus Genotype
The organelles (two) that are the "brain/control center" of the cell and the storage area of the cell.
What are the nucleus and the vacuole?
The organelles (two) that are the "powerhouse" that produces most energy for the cell and the "mailroom" of the cell
Oxygen + Glucose ----> Carbon Dioxide + Water + Energy
What is the Respiration equation?
Carbon dioxide + water ----> Oxygen + Glucose
What is the photosynthesis equation?
A chart that shows all possible combinations of alleles that can result from a genetic cross
What is a Punnet square?
Organelles (2) that are the passageways to move materials and break down large food molecules or old cells
What are Endoplasmic reticulum and Lysosomes?
Organelles (2) that produce proteins and capture sunlight
What are ribosomes and cholorplasts?
Frist three phases of the cell cycle
Interphase- cell matures and makes copies of DNA
Prophase- condense from of chromosomes, spindle fibers forming
Metaphase- chromosomes line up across the center attached to a spindle fiber
The second three phases of the cell cycle.
Anaphase- chromosomes split apart into chromatids towards opposite ends
Telophase- new nuclei begin to form around the 2 sets of chromatids
Cytokinesis- final stages of mitosis, the cell membrane pinches in the middle
An abnormal condition that a person inherits through genes or chromosomes
What is a genetic disorder?
