Organelles
A system of fibers found in both prokaryote and eukaryote that provides structure and serves to move substances around the cell.
What is a cytoskeleton?
Bacteria are this type of cell.
What is unicellular?
or
What is prokaryote?
This type of transport across a cel membrane requires no energy.
What is passive transport?
The range of temperatures, salinity, pH, etc that is an organism's best living conditions.
What is the optimal range?
This type of energy across a cell membrane requires the use of energy.
Genetic material in a prokaryote is found here.
What is a nucleoid?
The process by which a cell maintains stable conditions in its external environment.
What is homeostasis?
A type of diffusion that moves water molecules from a place of higher concentration to a place of lower concentration.
What is osmosis?
A cell quickly dies when it finds itself outside of this.
What is the range of tolerance?
Something that has a high solute concentration and a lower water concentration in comparison to the other side of a semipermeable membrane (ie. cell).
What is hypertonic?
NOT a membrane-bound organelle, and is found in both prokaryotes and eukaryotes that serves to "read" RNA and assemble proteins.
What is a ribosome?
These organelles found in plant cells have turgor pressure, that help a cell maintain its shape internally.
What are central vacuoles?
When the inside of a cell and the solution it is in contain equal amounts of solute, it is this kind of solution.
What is isotonic?
This allows some particles in a solution to pass through in both directions.
What is a semi-permeable membrane?
These organelles contain digestive enzymes for breaking down used cell parts and removing waste products. The "garbage collectors" of the cell.
What are lysosomes?
Chloroplasts and leucoplasts are examples of a type of organelle that has pigment or food for the cell.
This organelle receives substances from the endoplasmic reticulum and packages those substances into vesicles.
What is the Golgi Apparatus?
When a solution surrounding a cell has a lower solute concentration and higher water concentration in a solution.
What is hypotonic?
What is a negative feedback loop?
Two extensions of the cytoskeleton that help provide a cell with propulsion.
Genetic material within a nucleus that consists of DNA, RNA, and associated proteins.
What is chromatin?
The two components of cell theory that incorporate ideas such as heredity, metabolism, and chemical composition that all modern cytology is based on.
What is
1. Cells are the structural and functional units of all living things.
Cells can only come from other preexisting cells.
Tis cell transports compounds around the cell and helps the cell maintain shape; it is studded with ribosomes and process the proteins made by the ribosomes.
What is the rough endoplasmic reticulum?
This type of feedback does not have a way of returning something to a baseline.
What is a positive feedback loop?
An often slimy coating that surrounds the cell of a bacterium to prevent it from drying up.
What is a capsule?
