True or false
True of false, Cytoplasm keeps all the cellular organelles suspended and helps in the movement of the cell through the streaming process.
True
What functions as a micro-machine for making proteins
Ribosomes
What cell functions like a principles office
Nucleus
Any living thing is known as an
Organism
Who was the first person to see cells under the microscope and give them a name?
Robert Hooke
True or false, A vacuole is a cell organelle. It functions as a micro-machine for making proteins. vacuoles are composed of special proteins and nucleic acids
False
What creates the outer boundary of the cell and keeps the cell together and controls entry and exit of material from the cell
Cell membrane
What types of organisms have cells with very large vacuoles?
Plants
A plant grows toward the light. The plant's action is an example of
a response
He discovered that all plants were made of cells, which contributed to the development of the cell theory
Matthias Jakob Schleiden
True or False, smooth ER is a membranous organelle found in most eukaryotic cells. Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts and the storage and metabolism of calcium ions within the cell.
True
controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.

He advanced the cell theory with his conclusion that cells could only come from other cell
Theodor Schwann
True or false, The Golgi body serve to direct the movements of microtubules and other cytoskeletal structures and proteins, ultimately allowing large changes to the shapes of animal cell membranes.
False
What are generally small and help sequester waste products.
Vacuole
Through which cell structure does waste exit the cell?
Cell membrane

Living
used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular level. His work made it more clear that diseases occur at the cellular level. His work led to scientists being able to diagnose diseases more accurately
Rudolf Virchow
True or false, rough ER creates the outer boundary of the cell and keeps the cell together, and it controls entry and exit of material from the cell.
False
What breaks down excess or worn-out cell parts and they may be used to destroy invading viruses and bacteria.
Lysosomes
Which type of cell has the closest thing resembling a human skeletal system, which provides shape and structure?
Plant cell
What is an increase in the amount of living material and/or the formation of new structures ?
Growth
laid the foundations of plant anatomy and became an expert on animal reproduction. He discovered blood cells and microscopic nematodes, and studied the structure of wood and crystals. He also made over 500 microscopes to view specific objects.
