The brain of the cell
Nucleus
a groups of cells working together
tissue
Main function of circulatory system
transport material and oxygen throughout the body
Biotic or Abiotic - insects, animals, plants
Biotic or Abiotic - amount of sunlight, temperature, amount of water
Abiotic
provides protection, structure, and shape
Cell Wall
a group of tissues working together
organ
main function of digestive system
break down and absorb food
Why is offspring identical in asexual reproduction
Only 1 parent, so only 1 set of genetic information
Why is offspring different in sexual reproduction?
Genetic info comes from 2 different parents
Where photosynthesis happens

organ system
Which systems interact and coordinate all body systems?

natural selection
What pathway do most nutrients take after you take a bite of food?
digestive system -> circulatory system -> body cells
Controls what goes in and out of the cell
Cell Membrane
Organization of life, from simplest to most complex
cells -> tissues -> organs -> organ systems
Which body system includes the lungs, nose, and mouth?
Respiratory
cell wall and chloroplast
Three reasons why animals move
to find food/water
to find shelter
to find a mate
