Cell Theory Timeline
Who made the microscope and said that "Everything is made up of smaller structures named cells."
Robbert Hook, 1669.
A thin, dynamic, and semipermeable barrier that surrounds all living cells, separating the interior cytoplasm from the outside environment.
A cell membrane.
When a cell grows, is it a function or a structure?
A function.
Cells that are plant have two different kinds of defense systems. What are they?
A cell membrane or cell wall (plants also have a cell membrane).
A rigid, non-living, and permeable outer layer that surrounds the plasma membrane of plant, bacterial, fungal, and some protist cells.
In 1694, what did Anthony Van Leeuenhoek.
Contributed to making better microscopes and saw living cells from pond water.
What is a vacuole?
A vacuole is a membrane-bound organelle found in the cytoplasm of plant, animal, and protist cells, primarily acting as a storage sac for water, nutrients, pigments, or waste products.
When a cell develops something, is it a function or structure?
Structure.
What makes cells eukaryotic?
A nucleus.
What is a central vacuole?
A vacuole is a membrane-bound organelle found in the cytoplasm of plant, animal, and protist cells, primarily acting as a storage sac for water, nutrients, pigments, or waste products, but place in the center of the cell, which got its name "central vacuole."
Discovered that plants are made out of cells. Who made this discovery?
Matthis Shnider.
What do centrosomes do?
Makes the cellular division process.
Is cellular division a function or structure?
A function.
Both.
What are chloroplasts?
Chloroplasts are specialized organelles found in plant cells and eukaryotic algae that conduct photosynthesis, converting light energy into chemical energy (glucose) to fuel the organism.
What did Robert Brown discover in a cell?
A nucleolus.
What are lysosomes?
Vesicles filled with digestive enzymes that break down waste and debris.
What is classified as a structure?
An organelle.
Can ribosomes be free, or attached to a cell?
Yes, since they need to synthesis proteins.
What is chlrophyll?
Chlorophyll is the green pigment found in the chloroplasts of plants, algae, and cyanobacteria that absorbs sunlight to drive photosynthesis, converting light energy into chemical energy (glucose).
Theodor Shawn, discovered and concluded what?
That animals have cells, which was proven as technology advanced.
What breaks down cellular animal waste?
lysosomes.
What is classified as a fucntion?
How a cell works.
Do eukaryotes have membrane-bounded organelles?
Yes.
Can plants do photosynthesis or eat like regular animals?
Both, depending on the organism (Venus fly trap).
