Life and Living Things
What is one thing all living things must do to stay alive?
Reproduce, use energy, grow, respond to environment, eat, or maintain homeostasis
Which type of cell does NOT have a nucleus: prokaryotic or eukaryotic?
Prokaryotic
Pro - NO
Euk - Nukes
What organelle is considered the "brain" of the cell
Nucleus
Which word is NOT one of the four main biomolecules?
Protein, Carbohydrate, Substrate, Lipid, Nucleic Acid
Substrate
Speed Up
Name two basic needs that most living things require to live (give two).
Examples: food (energy), water, air, shelter;
Name one living thing made of prokaryotic cells and one made of eukaryotic cells.
Pro: Bacteria
Euk: Humans, Animals, Plants
What organelle is considered the "Powerhouse" of the cell?
Mitochondria
What biomolecules helps build and repair body parts? (Found in muscles, skin, hair, nails)
Protein
Enzymes work on specific molecules called what?
Substrates
Cells are considered which of the following:
A. Only something you see in prison
B. The device you use to call/text people
C. Make up all living things, One or more in every living thing
List two organelles that eukaryotic cells have that prokaryotic cells usually do not.
Examples: nucleus, membrane-bound organelles (mitochondria, chloroplasts, endoplasmic reticulum).
Which organelle makes protein for the cell?
A. Ribosome
B. Cell Wall
C. Mitochondria
D. DNA
Which word is NOT a Monomer?
Fatty Acid - Amino Acid - Monosaccharide - Nucleotide - Enzyme
Enzyme
How can temperature effect Enzymes?
Heat can "denature" or destroy the enzyme
Give one example of how organisms respond to their environment
Example: a plant bending toward light (phototropism); animals moving away from danger.
Explain in why eukaryotic cells are considered more complex than prokaryotic cells.
Because eukaryotes have membrane-bound organelles and a nucleus, allowing specialized functions in different parts of the cell.
The cell membrane and cell wall is like which human body part?
A. Brain
B. Skin
C. Heart
D. Stomach
List the four Polymers and the four Monomers
Monomers: Fatty Acid Amino Acid Monosaccharide Nucleotide
_____ are the chemicals found at the beginning of the reaction (Product or Reactant)
_______ are the chemicals found at the end of the reaction (Product or Reactant)
Reactant - Product
What does MRS GREN stand for? (list what each letter stands for)
Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion, Nutrition
Where is DNA located in a prokaryotic cell and where is DNA located in a Eukaryotic cell
Pro: floating around in the cell
Euk: inside the nucleus
What two organelles are found in plant cells, but not animal cells?
A. Cell Wall, Mitochondria
B. Cell Membrane Nucleus
C. Cell Wall Chloroplast
D. Ribosome, Chloroplast
Give an example of food for each type of Biomolecule:
Protein
Carbohydrate
Lipid
Protien: meat
Carbohydrate: pasta, fruit (almost anything)
Lipid: oil, butter
Coach Sneed used the example to describe enzymes as a lock and key. Using the following words to describe each part of the lock and key.
Substrate Enzyme Activation site Product
Enzyme - Lock
Substrate - Key
Activation site - key hole
Product - unlocked lock
