Early Discovery of the cell
First to observe living microorganisms.
Who is Anton Van Leeuwenhoek
Cells that do not enclose their DNA in nuclei.
What are prokaryotes.
The organelle that makes ribosomes
What is the nucleolus
A thin flexible barrier surrounds the cell.
What is the cell membrane.
The movement of molecules across the cell membrane without using cellular energy.
What is passive transport.
Looked at slices of cork under a microscope and saw thousand of tiny empty chambers.
Who is Robert Hooke
Cells that enclose their DNA in nuclei.
What are eukaryotes.
Organelle where proteins are assembled.
What are ribosomes.
All cells, at some point in their lives, contain DNA.
What is a cell membrane.
The passive movement of molecules along the concentration gradient.
What is facilitated diffusion
Light passes through a specimen, resulting in a specimen, and the resulting image is enlarged.
What is light microscope
Membrane proteins are completed.
What is the Rough ER.
Some molecules can diffuse across the lipid bilayer but other cannot.
What is semi-permeable.
Movement of ions or molecules across a cell membrane.
What is active transport.
Cell structures and large protein molecules, images appear flat & 2-dimensional.
What is a transmission electron microscope (TEM).
What is plant cell.
The organelle that gives purposes.
What is the Golgi apparatus.
A fundamental structure of the membrane.
What is the phospholipid bilayer
Movement of water across a semipermeable membrane.
What is osmosis.
3-D images of a specimen´s surface.
What is a scanning electron microscope (SEM).
The cell that does not have a cell wall
What is Animal cell
The organelle that transports proteins.
What is the Vesicle.
Transport and fusion of secretory vesicles with the plasma membrane.
What is exocytosis.
