Characteristics of Life
All living things are made of these basic units
Cells
These cells have a cell wall and chloroplasts and can perform photosynthesis
Plant cells
This organelle is known as the "powerhouse of the cell" due to its role in energy production
Mitochondria
These cells remember past infections and help the body respond faster the next time
Commonly referred to as a "germ"
Pathogen
This process, fundamental to all living things, allows organisms to produce offspring.
Reproduction
These cells lack a nucleus and membrane-bound organelles.
Prokaryotic cells
This organelle, found only in plant cells, is the reason why plants can appear green
Chloroplast
These cells fight off germs and infections
White blood cells
These microscopic, living organisms are responsible for causing many common infections and diseases
Bacteria
This process involves breaking down food to get energy
Digestion
Humans are an example of this type of organism, made up of many specialized cells
Multicellular organisms
Plant cells contain this structure, absent in animal cells, which provides rigidity and protection
Cell wall
These proteins help to protect the body by attaching to germs
Antibodies
This type of bacteria can cause food poisoning and is often found in undercooked meat
Salmonella
This characteristic means that living things can change over time to better fit their environment
Adaptation
These cells have a nucleus and membrane-bound organelles, and make up plants and animals
Eukaryotic cells
This organelle modifies, sorts, and packages proteins and lipids for storage or transport out of the cell
Golgi Apparatus
This type of immunity develops after you get a disease or a vaccine
Acquired immunity
This outer layer of many bacteria provides protection and shape
Cell wall
A type of room called a Cell
This type of cell can perform all the necessary functions of life within a single cell
Unicellular
This organelle is responsible for protein synthesis and can be found attached to the rough endoplasmic reticulum
Ribosome
This type of immunity involves the body’s natural response to pathogens without medical intervention
Natural immunity
These tiny hair-like structures on the surface of some bacteria help them move and adhere to surfaces
Pilli and flagella
