The smallest unit of life
What is a cell?
Most common type of microscope used by biology students
What is a light microscope?
Name of organelle that controls the cell
What is the nucleus?
Collection of fibrous proteins which give the cell its shape
What is the cytoskeleton?
Proteins destined for export from the cell are made at ribosomes attached to this organelle
What is the RER (rough endoplasmic reticulum)?
First human to look at cells using a crude microscope
Who is Robert Hooke?
Microscope that takes x-ray pictures of cells
What is a transmission electron microscope?
Fancy name for the membrane that surrounds the nucleus
What is the nuclear envelope?
Train tracks for movement of transport vesicles
What are microtubules?
Active transport process which exports materials from the cell
What is exocytosis?
Theory based on work by Schleiden, Schwann, and Virchow
What is the cell theory?
Permits visualization of surface textures and contours
What is scanning electron microscopy?
Place where ribosomes are made
What is the nucleolus?
Fibers that move chromosomes around during cell division
What are microtubules?
Organelle in which proteins get carbohydrates attached
What is the Golgi?
First person to observe "animalcules" in pond water
Who is Anton van Leeuwenhoek?
Total magnification when a 10X objective is paired with a 50X objective
What is 500X?
Holes in the nuclear envelope that allow materials in/out of the nucleus
What are nuclear pores?
The rebar of the cell
What are intermediate filaments?
Complex of folded membranes where lipids are made and attached to proteins
What is the SER (smooth endoplasmic reticulum)?
Origin story theory for mitochondria and chloroplasts
What is the endosymbiotic theory?
What is the wavelength of visible light?
Form of DNA that is usually found in the nucleus; the loose-spaghetti form of DNA
What is chromatin?
Protein fibers found just underneath the cell membrane
What are microfilaments? (actin filaments)
Cellular "uber" which shuttles proteins from the endoplasmic reticulum to the Golgi
What is a transport vesicle?
