Organelles
This organelles surrounds all plant, animal, and prokaryotic cells.
Cell/plasma membrane
Name two of the four types of organisms that are considered eukaryotes.
Plants
Animals
Protists
Fungi
Atoms bond together to form...
Molecules
This type of atom can make long chains and rings due to being able to form 4 covalent bonds with other atoms.
Carbon
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?
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
Water sticks to other water molecules through hydrogen bonds.
What property of water is this?
Cohesion
Fats, oils, and waxes; monomers are glycerol and fatty acids; provide long term energy storage + make up the cell membrane
Which macromolecule is described here?
Lipids
What is the term for the chemical reactions that occur in cells?
Metabolism
This organelle uses the information from DNA to make proteins.
Ribosome
Mitochondrion
Nucleus
Endoplasmic reticulum
Golgi apparatus
Lysosome
Vacuole
Chloroplast
Water molecules have a positive side and a negative side, allowing them to form hydrogen bonds with any other atoms with a charge.
What word describes the charge on a water molecule?
Water is polar
Sugars and starches; monomers are monosaccharides like glucose; main source of energy for living things
Which macromolecule is described here?
Carbohydrates
What is the term for when organisms constantly work to maintain stable internal conditions?
Homeostasis
This organelle is used for cell storage. It is much larger in plant cells than it is in animal cells.
Vacuole
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
The atomic number of an element is equal to the _____ __ _____ in the atom's nucleus
Atomic number = Number of protons
DNA and RNA; their monomers are nucleotides - 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 breaks down unneeded materials in the cell, like a garbage disposal.
Lysosome
Identify 3 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
Adhesion is stronger than cohesion, due to this, water can climb up solid surfaces. Which property of water is this?
Capillary action
These molecules are the workforce of the body; they are made of amino acid monomers
Proteins
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
