Living Things
These 7 traits define all living organisms (move, respire, etc.).
What are the 7 characteristics of living things?
Jelly-like fluid inside the cell holding organelles.
What is cytoplasm?
Controls what enters/leaves all cells.
What is cell membrane?
Water diffusion across membrane.
What is osmosis?
Similar cells working together.
What is tissue?
Single-celled organism like an amoeba.
What is a unicellular organism?
"Powerhouse" organelle that makes energy from food.
What are mitochondria?
Photosynthesis in plants only.
What are chloroplasts?
Lets some things through.
What is selectively permeable?
Heart's 4 pumping/receiving rooms.
What are chambers?
Organism visible without a microscope, like a frog.
What is a macroscopic organism?
Theory stating all living things are made of cells from pre-existing cells.
What is cell theory?
Rigid plant support layer.
What is cell wall?
More solute outside, cell shrinks.
What is hypertonic?
4 types: muscle, epithelial, connective, nervous.
What are tissue types?
Moves using pseudopods, example of microscopic unicellular protist.
What is an amoeba?
Controls cell activities, holds DNA; in center of eukaryotic cells.
What is the nucleus?
Big storage sac, larger in plants.
What is vacuole?
Less solute outside, cell swells.
What is hypotonic?
Cells rely on each other.
What is cell interdependence?
Chemical process releasing energy from food (glucose + oxygen → ATP + CO2 + water); happens in all living cells/mitochondria.
What is respiration?
Wet-mount slide prep uses this tool to view tiny cells/organs.
What is a microscope?
No wall/chloroplasts; flexible, smaller vacuoles.
What is animal cell?
Particles always moving, spread high to low (explains diffusion).
What is particle theory?
Heart/lungs/vessels transport blood/O2 in loop.
What is circulatory system?
