This organelle surrounds ALL CELLS.
It controls what enters and leaves a cell.
Cell/plasma membrane
Name two types of organisms that are considered eukaryotes.
Plants
Animals
Protists

Molecules
Sugars and starches; they're the main source of energy for living things
Which macromolecule is described here?
Carbohydrates
A scientist examined a slice of a leaf and a slice of a human organ under a microscope and observed that they were both made of similar structures.
Which characteristic of living things does this best represent?
All living things are made of cells
This organelle provides the cell with energy by performing cellular respiration.
Mitochondrion (Mitochondria)
Name the two organelles that are only found in plant cells (not animal cells).
Chloroplasts and Cell wall
What is the smallest number of cells a living thing can have?
1 cell
Fats, oils, and waxes; They make up the cell membrane
Which macromolecule is described here?
Lipids
What is the term for when organisms constantly work to maintain stable internal conditions?
Homeostasis
This organelle is the "goo" (liquid) that fills up cells and holds the other organelles in place.
Cytoplasm (cytosol)
Identify 3 "membrane-bound organelles" that would only be found in eukaryotic cells
Mitochondrion
Nucleus
Endoplasmic reticulum
Golgi apparatus
Lysosome
Vacuole
Chloroplast
What is the term for organisms with only 1 cell?
What is the term for organisms with more than one cell?
Unicellular (single-celled)
Multicellular
The maximum number of covalent bonds that carbon can form with other atoms
4 covalent bonds
What is the term for the chemical reactions that occur in cells?
Metabolism
This organelle makes proteins.
Ribosome
Describe the difference in the location of DNA in prokaryotic cells vs eukaryotic cells.
Prokaryotic cells: DNA floats in the nucleoid region
Eukaryotic cells: DNA is packaged up in the nucleus
Organize these terms smallest to largest:
Atom --> Molecule --> Macromolecule --> Cell --> Organelle
DNA and RNA; their function is to store genetic information
Which macromolecule is described here?
Nucleic acids
Wolves are carnivores, they must hunt for prey like rabbits in order to stay alive.
Which characteristic of living things does this statement best demonstrate?
Energy and metabolism
This organelle is used for cell storage. It is much larger in plant cells than it is in animal cells.
Vacuole
Identify 2 structural differences between prokaryotic cells and eukaryotic cells
Prokaryotic cells are smaller, Eukaryotic cells are larger
Prokaryotic cells are simple, Eukaryotic cells are complex
Prokaryotic cells are always 1 cell, eukaryotes can have more than one
Prokaryotes do not have membrane-bound organelles, eukaryotes do
Eukaryotic cells store DNA in a nucleus
Groups of similar cells are referred to as _____. These come together to make up organs.
Tissues
What does organic mean in science? (two things)
Comes from a living thing and contains carbon
When we get to hot, we sweat to release heat. When we get to cold, we shiver to generate heat.
Which characteristic of living things does this best represent?
Homeostasis
