Characteristics of Life
Living things are made up of these.
What are cells?
Letter A in the cell diagram is this.
What is the cytoplasm?
A cell's function is determined by this.
What is its structure?
When some things are allowed through but others aren't, we use this term.
What is semi-permeable?
When someone is unfairly for or against someone or something it can affect their judgment. It's called this.
The difference between biotic and abiotic things is this.
What is biotic are living and abiotic are not?
Letter C in the diagram is this.
What is the cell wall?
This is a subsystem of an organ.
What is tissue?
The cell membrane is made of this many layers.
What is 2?
These cells can be altered to do any type of job.
What are stem cells?
Viruses are not able to do this on their own. They need a host cell.
What is replicate/reproduce?
Letter B in the diagram is this.
What is the nucleus?
When one organ system is affected by disease, other organ systems often follow. It's because of this.
What is because they're interrelated or interdependent?
What is a lock and key?
This is a bacteria, virus, or other microorganism that causes disease.
What is a pathogen?
Living things need energy. This organelle converts nutrients into energy for the cell.
What is the mitochondria?
Letter D in the diagram is this.
What is the mitochondria?
This is a subsystem of an organism.
What are organ systems?
This is the function of the cell membrane.
What is to protect the cell and let things in and out?
This protein-coated genetic material is capable of infecting living things. It is not living itself though.
What is a virus?
Living things can maintain homeostasis. Homeostasis is this.
What is maintaining a stable internal environment?
This organelle is the control center for the cell and contains its genetic material.
What is the nucleus?
Cells are different from each other in these ways.
What is their structure, function, and size?
These are embedded into the cell membrane and allow things to pass in and out of the cell.
What are proteins?
When something is so small that we can't see it with the naked eye, we refer to it with this word.
What is microscopic?
