Cells & Organisms
These types of cells have a nucleus and membrane-bound organelles
What are eukaryotic cells?
An organelle that is involved in synthesizing lipids
What is the smooth ER
An area within the cell where ribosomes are synthesized
What is the nucleolus
Hair-like things that protrude from some eukaryotic cells
What are cilia?
A term used to describe that the cell membrane allows some but not all substances to pass through
What is semi-permeable?
This cell type tends to have chloroplasts and a large central vacuole
What is a plant cell?
An organelle that sends out vesicles containing proteins to their final destination
What is the Golgi?
The process within plant cells that produces glucose and oxygen
What is photosynthesis?
Tail-like things that protrude from some eukaryotic and prokaryotic cells
What are flagella?
Membrane proteins that receive signals from outside the cell and trigger a cellular response
What are receptor proteins?
According to cell theory, this is where all cells arise from
What are other cells?
Organelles that make ATP
What are mitochondria?
The process within cells that requires oxygen and breaks down glucose
What is cellular respiration?
The theory about the cell membrane that describes the movement of proteins and lipids within the membrane
What is the fluid mosaic model?
The term used to describe what the cell membrane is made of
What is a phospholipid bilayer?
These organisms are always unicellular and their cells do not contain a nucleus
What are prokaryotes?
Organelles that convert light energy into chemical energy
What are chloroplasts?
The organic compounds found within lysosomes
What are digestive enzymes?
Membrane proteins that help other cells (and scientists) identify the cell
What are cell surface markers?
Membrane proteins that help move substances in and out of the cell
What are transport proteins?
This feature enables efficient transport in and out of cells and occurs when cells are very small
What is high surface-to-volume ratio?
Organelles that are not membrane-bound and synthesize a specific type of organic compound by putting together amino acids
What are ribosomes?
The form of DNA when the cell is preparing to divide
What are chromosomes?
Strings of proteins within the cell that help support cell shape and movement
What is the cytoskeleton?
Folds in the cell membrane that increase surface area to improve absorption efficiency
What are microvilli?
