Cell Theory and Basic
This tenet of the Cell Theory states that all cells come from these
What are other cells?
This organelle is known as the "powerhouse" because it breaks down food to release energy as ATP.
What is the mitochondria?
This category of transport requires no extra energy as molecules move from high to low concentration.
What is passive transport?
his is the need for an organism to stay stable by regulating its internal conditions.
What is homeostasis?
This is the longest phase of the cell cycle, consisting of G1, S, and G2 stages.
What is Interphase?
This term describes an organism composed of many cells that may organize into tissues and organs.
What is multicellular?
This organelle contains the genetic material and protects the DNA that controls cell activities.
What is the nucleus?
This term means the cell membrane is "picky" about what molecules can pass through easily.
What is selectively permeable?
This is a change in an organism's environment, such as a change in temperature or pH.
What is a stimulus?
During this stage of mitosis, chromosomes line up in the middle of the cell.
What is metaphase?
These four structures are found in ALL cells, regardless of whether they are prokaryotic or eukaryotic.
What are genetic material (DNA/RNA), cytoplasm, cell membrane, and ribosomes?
These organelles are responsible for making proteins and can be found on the Rough ER or floating in the cytoplasm.
What are ribosomes?
This specific type of passive transport is the simple diffusion of water across the cell membrane.
What is osmosis?
In this type of feedback loop, the output of a system causes a counter-response to return to a set point.
What is negative feedback?
This term refers to uncontrolled cell division that occurs when regulation of the cell cycle fails.
What is cancer?
Unlike eukaryotes, these cells lack a nucleus and membrane-bound organelles.
What are prokaryotic cells?
This organelle processes, sorts, and ships proteins where they are needed, often using vesicles.
What is the Golgi apparatus?
This type of active transport uses energy to move ions like Sodium (Na+) and Potassium (K+) against the concentration gradient.
What are molecular pumps? (or protein pump)
When a cell is placed in this type of solution, water moves into the cell, causing it to swell.
What is a hypotonic solution?
These undifferentiated cells can become one or more types of specialized cells.
What are stem cells?
This part is found in both prokaryotes and animal cells that whips around.
What is a flagella?
These threadlike fibers made of proteins give the cell its shape and can move organelles around.
What is the cytoskeleton?
This process uses vesicles to export large materials, such as neurotransmitters, out of the cell.
What is exocytosis?
This describes a state where internal conditions are not always the same but stay within a stable range.
What is dynamic equilibrium?
This is a process of programmed cell death used to eliminate webbed fingers during human development.
What is apoptosis?
