Organs that work together form this larger system.
What is an organ system?
This is an example of a single-celled organism.
What is a bacterium, protozoa, algae, or yeast?
In this type of solution, a cell loses water and shrinks.
What is a Hypertonic solution?
This type of feedback increases the rate of a process.
What is positive feedback?
The stable internal balance within an organism
What is homeostasis?
In multicellular organisms, similar cells that work together form this.
What is a tissue?
An organism whose cells have a true nucleus is called this.
What is a eukaryote?
When molecules move freely through the membrane from high to low concentration, this process occurs.
What is diffusion?
This process allows a cell to take in large particles by engulfing them.
What is Endocytosis?
Diffusion of water through a semipermeable membrane.
What is osmosis?
A group of tissues working together to perform a function forms this.
What is an organ?
These are the two main differences between prokaryotic and eukaryotic cells.
What is the presence of a true nucleus and membrane-bound organelles?
This is why a goldfish would die in the ocean.
What is it can’t maintain homeostasis in a hypertonic environment?
This process releases materials from a vesicle outside the cell.
What is Exocytosis?
This kind of transport requires energy from the cell.
What is active transport?
This term describes a group of unicellular organisms living together but able to function independently.
What is a colony?
This type of organism is made of only one cell?
What is Unicellular organism?
This is what modern cell theory states about the origin of cells.
What is all cells come from preexisting cells?
These are the four factors that affect whether a particle can passively cross a membrane.
What are the particle size, shape, polarity, and membrane composition?
Movement of molecules from high to low concentration without energy is called this.
What is passive transport?
This is the last in this series, cell → tissue → organ → organ system → ____________?
What is organism?
The cell membrane is made up mainly of this molecule type.
What are phospholipids?
This scientist’s work helped establish that cells come from other preexisting cells.
Who is Rudolf Virchow?
The stable internal balance within a living organism is called this.
What is homeostasis?
This type of diffusion differs from simple diffusion because it uses protein channels in the membrane.
What is facilitated diffusion?
