Cell Me Something I Don't Know
This scientist helped establish that all cells come from existing cells in the 1860s (in addition to his work in making milk safer to drink).
Who is Louis Pasteur?
Known as the "powerhouse of the cell," this organelle releases energy as ATP.
What is the mitochondria?
This is the term for an organism's need to stay stable by regulating its internal conditions.
What is homeostasis?
This type of transport requires no energy and moves substances from high to low concentration.
What is passive transport?
The two main purposes of the cell cycle are growth and this.
What is repair?
This term describes an organism made of only one cell.
What is unicellular?
This organelle processes, sorts, and ships proteins in vesicles.
What is the Golgi apparatus?
In this type of feedback loop, the output intensifies the response — like contractions during childbirth.
What is a positive feedback loop?
In osmosis, a cell placed in this type of solution will shrivel because water moves out.
What is a hypertonic solution?
During this phase of mitosis, chromosomes line up in the middle of the cell.
What is metaphase?
Eukaryotic cells divide by this process, while prokaryotic cells use binary fission.
What is mitosis?
Found only in animal cells, these structures appear during cell division and help pull chromosomes apart.
What are centrioles (or centrosomes)?
This type of feedback loop counteracts change and returns the system to a set point -- like body temperature regulation.
What is a negative feedback loop?
This form of passive transport uses a protein channel to help large or polar molecules like glucose cross the membrane.
What is facilitated diffusion?
These undifferentiated cells can develop into one or more types of specialized cells.
What are stem cells?
These are two things that are found in ALL cells, whether prokaryotic or eukaryotic.
What are:
Genetic Material
Cytoplasm
Cell membrane
Ribosomes
Lysosomes are only found in this type of cell.
What is an animal cell?
This is the term describing a change in the environment that an organism must respond to.
What is a stimulus?
White blood cells use this active transport process to engulf and destroy bacteria.
What is endocytosis?
A tumor is described as malignant when its cells do this -- spreading to other parts of the body.
What is metastisize?
Membrane-bound organelles are only found in this type of cell.
What is a eukaryotic cell?
This organelle, only found in plant cells, has grana and stroma.
What is a chloroplast?
Homeostasis is described as this type of equilibrium because conditions stay within a range, not at a fixed point.
What is dynamic equilibrium?
Nerve cells use this active transport process to release neurotransmitters out of the cell.
What is exocytosis?
What is apoptosis?
