Characteristics of Life
True of False: To be considered living, an organism needs to show ALL of the characteristics of life
TRUE
Cells
What organelle is the "brain of the cell" that holds genetic information?
The nucleus
What are the TWO major categories of cells that all cells fall into.
Prokaryotes and Eukaryotes
True or false: Bacteria (prokaryotes) have a cell wall
True
What is the difference between UNICELLULAR and MULTICELLULAR? (Define both)
Unicellular - Organism made of 1 cell
Multicellular - Organism made of many cells
What level of organization is a "heart" an example of?
Organ
What organelle uses sunlight to make food energy for the cell?
Chloroplast
Which type of cell uses CHLOROPLASTS to make its own food using sunlight? (Plant cell or Animal cell?)
Plant Cell
Which characteristic of life is "maintaining an internal balance"? For example, maintaining a stable body temperature, pH, or blood sugar levels.
Homeostasis
The process by which one organism makes one or more new organisms.
Reproduction
What level of organization is "a group of cells working together"?
Tissues
What organelle uses food to make energy for the cell?
Mitochondria
What is at least ONE example of a prokaryote?
What is at least ONE example of a eukaryote?
Prokaryote: Bacteria, Archaea
Eukaryote: Plant, Animal, Fungus, Protist, etc.
Name the specialized structures used by the unicellular organisms (amoeba, paramecia, euglena, and volvox) for locomotion or movement.
Amoeba move via pseudopodia ("false feet"), Paramecium use hair-like cilia, and both Euglena and Volvox utilize whip-like flagella to propel themselves through water.
Which characteristic of life is "the sum of all of the chemical reactions in a cell"?
Metabolism
What level of organization is "two are more atoms bonded together"?
Molecule
What is the function/job of the RIBOSOME?
To make proteins.
Which type of cell has NO nucleus? (Prokaryote or Eukaryote)
Prokaryote
Name at least THREE specialized organelles/structure that are present in animal cells but different or not present in plant cells.
1. small or no vacuole
2. can be of any shape; commonly circular
3. lysosome
4. flagella
Give at least THREE key characteristics of life.
organization (cells); metabolism (energy processing); homeostasis; growth and development; reproduction; response to stimuli; evolution and adaptation
Put the following levels of organization in order from SMALLEST to LARGEST: Organism, Cell, Organ System, Tissue, Organs
Cell, Tissue, Organ, Organ System, Organism
What is the function/ job of the GOLGI APPARATUS?
PACKAGE and PROCESS proteins
What THREE organelles do plant cells have that animal cells do NOT have?
Cell Wall, Large Vacuole, Chloroplast
What are 3 structures ALL cells have?
Plasma membrane (or cell membrane)
DNA/RNA
