Organelles
Produces ATP within the cell.
What is the Mitochondria?
The third principle of cell theory states that all cells come from this.
What are pre-existing cells?
Transport that requires no energy from the cell.
What is passive transport?
The maintenance of stable internal conditions
DNA is copied during this phase of interphase.
What is S phase?
These small structures in the cell build proteins.
What are ribosomes?
This type of cell has no nucleus and no membrane-bound organelles.
What is a prokaryotic cell?
The diffusion of water across a membrane.
What is osmosis?
This type of feedback loop reverses a change, like sweating to cool the body.
What is negative feedback?
The four phases of mitosis, in order.
What are Prophase, Metaphase, Anaphase, and Telophase
This organelle modifies, packages, and ships proteins in vesicles.
What is the Golgi apparatus?
Name two structures found in plant cells but not animal cells.
What are the cell wall, chloroplasts, and a large central vacuole?
A cell placed in a solution with a higher solute concentration than that inside the cell. It will shrink in this type of solution.
What is hypertonic?
Childbirth contractions and blood clotting are examples of this type of feedback.
What is positive feedback?
Chromosomes line up along the middle of the cell during this phase.
This organelle holds digestive enzymes that break down waste and worn-out organelles.
What is the lysosome?
A cell has a nucleus, centrioles, and no cell wall.
What is an animal cell (eukaryotic)?
The cell engulfs a large particle by wrapping the membrane around it into a vesicle.
What is endocytosis?
An organism constantly adjusting around a set point is in this type of equilibrium
What is dynamic equilibrium?
In plant cells, cytokinesis forms this structure instead of pinching in.
What is a cell plate?
The nucleus, rough ER, ribosomes, and Golgi all support the production of this macromolecule.
What are proteins?
The cell membrane is made of a double layer of these molecules, with hydrophilic heads facing outward and hydrophobic tails facing inward.
What is the phospholipid bilayer?
A large molecule moves down its gradient through a channel protein with no energy used.
What is facilitated diffusion
The membrane helps maintain homeostasis because it is this, controlling what enters and leaves.
What is selectively permeable?
Each chromosome is copied during S phase, so a cell entering mitosis has chromosomes made of two sister chromatids joined at this region.
What is the centromere?
