Circulatory System Carries needed materials to the body cells; carries wastes away from body cells; helps fight disease
Digestive System Takes food into the body, breaks food down, and absorbs the digested materials. Endocrine: Controls many body processes –such as intake of sugar by cells –by means of chemicals
Excretory System Removes wastes.
Immune System Fights disease.
Muscular System Enables the body to move; moves food through the digestive system; keeps the heart beating.
Nervous System Detects and interprets information from the environment outside the body and from within the body; controls most body functions
Reproductive System Produces sex cells that can unite with other sex cells to create offspring; controls males and female characteristics.
Respiratory System Takes oxygen into the body and eliminates carbon dioxide.
Skeletal System Supports the body, protects it, and works with muscles to allow movement; makes blood cells and stores some materials
Skin Protects the body, keeps water inside the body, and helps regulate body temperature.
N Nitrogen
C carbon
CO2 Carbon dioxide
H Hydrogen
O Oxygen
H2O Water
P Phosphoruous
Ca Calcium
S Sulfur
Fe iron
NaCl Na is sodium. Cl is chlorine. This is table salt.
Photosynthesis reactants Carbon dioxide and water
Photosynthesis products Glucose and Oxygen
Cellular Respiration reactants Glucose and oxygen
Cellular Respiration products carbon dioxide, water, and ATP (energy)
storage in a plant and animal cell vacuole
produces power or energy for the cell mitochondrion
gives rigid structure to the cell cell wall
directs the activity of the cell nucleus
packages proteins and sends them out golgi apparatus
captures sunlight energy chloroplast
Endoplasmic Reticulum stores ribosomes and transports
allows materials in and out of the cell cell membrane
make proteins ribosomes
Tt heterozygous
tt homozygous recessive
TT homozygous dominant
diffusion of water osmosis
when substances move from an area of high concentration to an area of low concentration diffusion
The cell production process that creates two daughter cells. The process in which a cell is made without input from two different parents mitosis
The cell production process that creates sex cells. sexual reproduction – must have a haploid cell from each parent. Each parent is giving half the genetic information in order to create a full set of genetic code meiosis
living things biotic factor
non-living things such as sun, temperature, climate, water, atmosphere and soil abiotic factor
the organs of this system are heart, blood, blood vessels (arteries, veins and capillaries) Circulatory System
the organs of this system are hormones and glands Endocrine System
the organs of this system are compact bone, bone marrow, spongy bone Skeletal System
the organs of this system are smooth, skeletal and cardiac Muscular System
the organs of this system are brain, nerves, spinal cord, sensory organs Nervous System
the organs of this system are mouth, esophogus, stomach, pancreas, liver, gallbladder, small and large intestines. Digestive System
the organs of this system are lungs, trachea, mouth and nasal cavity Respiratory System
a place within the ecosystem where an organism lives habitat
what a species does in a habitat to survive niche
a close long term relationship between two species that usually involves an exchange of food or energy symbiosis
The process in which carbon in the atmosphere is used by producers to make glucose. Animals eat plants and die then decay. Carbon is returned to the soil. The burning of fossil fuels and cellular respiration return carbon back to the atmosphere. Carbon Cycle
Carbon dioxide and other gases are trapped in Earth's atmosphere. Thermal energy from the Sun keep Earth's temperatures warm. Greenhouse Effect
Plants give off oxygen during photosynthesis. Animals take in oxygen and release carbon dioxide to be used by producers in this cycle. Oxygen Cycle
Precipitation, Condensation, Evaporation, and Transpiration: Water moving through a continuous cycle. Water Cycle
in the water cycle when a liquid water changes into a gas called water vapor Evaporation
in the water cycle when water vapor changes into a liquid; Clouds are made in this process. Condensation
Water falls from clouds to Earth's surface. Precipitation
Water leaves cell and enters the environment and the atmosphere as water vapor. Transpiration
This is when an element is freed in the atmosphere to change into compounds that are fixed by bacteria to be used by plants. Plants are consumed by animals. Animals release waste or die to return the element back to the environment. Nitrogen Cycle
The stage where larva enters a chrysalis or a cocoon to transform into an adult. pupa
The young shed an exoskeleton several times before reaching adulthood nymph
the process in which the body changes completely from an egg to an adult metamorphosis
butterfly, ladybug, and moth are examples of this process complete metamorphosis
tick, grasshoppers, and frogs are examples of this process incomplete metamorphosis
both partners benefit from this symbiotic relationship mutualism
benefits one species but does not hurt or harm the other. Commensalism
benefits one species but harms the other from this symbiotic relationship Parasitism
largest number of individuals in one species that an environment can support Carrying Capacity
anything that restricts the size of a population such as sunlight, food, space, and water limiting factors
