What term is described as different types of cells playing different roles?
Cell specialization
Who used a single-lens microscope to observe pond water and other living things?
Anton van Leeuwnhoek
What is the difference between hydrophobic and hydrophilic?
Hydrophobic = Water hating
Hydrophilic = Water loving
What is described as a dotted structure with thousands of nuclear pores, which allow material to move into and out of the nucleus?
Nuclear Envelope
Which organelle is the "powerhouse of the cell"?
Mitochondria
Who first observed cork cells and gave them their name?
Robert Hooke
Which organelle is responsible for packaging and shipping proteins?
Golgi Apparatus
Which statement is NOT part of the cell theory?
A. All living things are made up of cells.
B. Cells are the basic unit of structure and function in living things.
C. New cells can be produced from nonliving matter.
D. All cells come from existing cells.
Which microscope(s) uses beams of electrons instead of light?
Both transmission electron microscope and scanning electron microscope.
Which organelle is responsible for storing materials like water, salts, proteins, and carbohydrates?
Vacuoles
Ancient bacteria and photosynthetic cyanobacteria took up residence inside the earliest eukaryotic cells and evolved into chloroplasts and mitochondria is known as:
Endosymbiotic Theory
Concentration of solutes is the same inside and outside the cell.
Isotonic
What is the model called that is described as the proteins embedded in the lipid bilayer, and their attached carbohydrates, can move around and “float” among the lipids?
Fluid Mosaic Model
The solution has a higher solute concentration than the cell
Hypertonic
Sometimes cells must transport materials against a concentration difference, requiring energy. For small molecules or ions to cross the cell membrane, they are generally carried across by transport protein pumps located in the membrane. This is through a process called:
Active Transport
The solution has a lower concentration than the cell.
Hypotonic
What is one difference between prokaryotic and eukaryotic cells?
Eukaryotes have a nucleus while Prokaryotes do not.
Structure in an animal cell that helps to organize cell division
Centrioles
Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis
Ribosomes
Internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled
Endoplasmic Reticulum
Cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell
Lysosomes
The center of an atom, which contains the protons and neutrons; in cells, structures that contain the cell’s genetic material in the form of DNA
Nucleus
Networks of protein filaments in a eukaryotic cell that give the cell its shape and internal organization and are involved in movement
Cytoskeleton
water channel protein in a cell
Aquaporin
on or in a cell, a specific protein to whose shape fits that of a specific molecular messenger, such as a hormone
Receptor
