CELLS
The main scientists involved in the development of the cell theory and what each of them contributed
- Botanist Matthias Schleiden determined all plants were made of cells - Biologist Theodore Schwann determined all animals were made of cells
What are the 3 fundamental ideas that make up the cell theory?
1. The cell is the basic unit of all living things 2. Cells perform all the functions of living things 3.Cells come from the reproduction of existing cells
Golgi apparatus
A cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell
Cytoskeleton
A network of fibers that holds the cell together, helps the cell to keep its shape
Lysosomes
An organelle containing digestive enzymes and they are found in eukaryotic cells
Who studied pond water and was the first to see living organisms under the microscope?
Anton Wan Lee
The word cylo means
Cell
This structure serves the outer boundary of the eukaryotic cell
Cell membrane
Vacuole
Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Eukaryotic cells
Contain a nucleus and other organelles that are bound by membranes.
The wheel under the stage that adjust the amount of light is called the
Diaphragm
What part of the cell serves to process package and export proteins?
Golgi apparatus
Endolasmic Reticulum (Smooth)
Involved in making lipids and has no ribosomes on it
Tiny structures that carry out cell functions are collectively called
Organelles
Mitochondria
Powerhouse of the cell, organelle that is the site of ATP (energy) production
Cell Membrane
Protects, transports, and communicates for the cell, it surrounds the whole cell and lets nothing bad go inside -it is made up of phospholipid Bilayer
Who was the first person to see cells under the microscope and give them a name?
Robert Hooke
To focus a spectrum, it is best to start with which objective
Scanning
prokaryotic cell
Singular cell organism that does not have a nucleus or other membrane-bound organelles. -circular DNA that is loose in the cell
When, using the high power objective, you should not adjust the
coarse focus
The jelly like interior of the cell is called the
cytoplasm
What part of the cell serves as the intracellular highway?
endoplasmic reticulum
Where are ribosomes usually located in animal and plant cells?
endoplasmic reticulum
What part of the cell is responsible for breaking down and digesting things?
lysosomes
Endoplasmic Reticulum (Rough)
makes proteins and has ribosomes
Unlike eukaryotes, prokaryotes do not have
membrane bound nucleus
Which technology was essential for the development of the cell theory?
microscopes
Where is DNA found?
nucleus
Chloroplasts
organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis solar———— chemical
What part of the cell makes proteins?
ribosomes
