branches of science/organelles pt 1
What are the three branches of science we break science into?
Life Science
Physical Science
Earth Science
B. Make proteins needed for chemical reactions
Ribosomes
Both plant and animal cells have a nucleus which makes them this type of cell
Eukaryotes
Timmy breathed in air into his lungs .Which organ system is he using right now?
Respiratory system
The earliest era from before life on earth began
Pre-cambrian era
What branch of science would you be studying if you researched the disease, diabetes?
Life Science
C. Outer solid layer that supports and protects the cell
Cell Membrane
This organelle only found in a plant cell is responsible for photosynthesis
chloroplast
If Timmy got sick, what organ system would he use to get rid of the pathogens?
Immunity System
This type of bacteria created oxygen that enables multicellular life to develop
cyanobacteria
Which branch of science would you be studying if you looked at weather patterns of hurricanes?
Earth Science
D. Stores water and waste in the cell
Vacuole
This organelle only found in plant cells helps give the plant structure and protects the cell
Cell Wall
Timmy felt that the pot was too hot to touch. Which system let him know that this was the case
Nervous system
so much oxygen was created by cyanobacteria that it caused this global extinction event by causing the earth to cool off and freeze
Snowball earth
Which of the following would likely be a study for an Earth Scientist?
A.) The study of a human disease that is spreading across the Earth
B.) The study of how plates in the Earth’s crust move because of convection currents in the mantle
C.) The study of how plants grow through photosynthesis
B.) The study of how plates in the Earth’s crust move because of convection currents in the mantle
E. Provides cell with energy so cell can work
Mitochondria
What is the cell organelle that breaks down food and releases energy?
mitochondria
Name three pieces in the nervous system
Brain -> spinal cord -> nerves
life began to form on land during this era
Paleozoic Era
A. Jellylike substance that hold the cell organelles.
Cytoplasm
F. Contains genetic information that controls the whole cell
Nucleus
What is the cell organelle that is the control center of the cell and has most of the DNA in the cell?
Nucleus
Timmy is digesting the food he ate for thanksgiving. Which organs are being used in this system? (Name them in the order that they go to first to last)
Mouth to Stomach to Small intestine to Large Intestine
This era is when he had dinosaurs and is split up into 3 periods: the Triassic, the Jurassic and the Cretaceous period
Mesozoic Era
