Cell Discovery
What invention in the late 1500s led to the discovery of cells?
Compound Microscope
What level of organization is the smallest and carries out all the basic functions of life?
the cell
Transports and processes proteins and lipids; may be rough or smooth.
Endoplasmic reticulum
Movement of substances without using energy.
Passive transport
Which compound carries genetic information?
Nucleic acids
Who was the first scientist to observe and name cells?
Robert Hooke
Which organelle is large and central in plant cells, storing water, nutrients, and waste?
Vacuole
Makes proteins for the cell.
ribosomes
The movement of particles against a concentration gradient using energy.
Active transport
Which compound provides quick energy for cells in the form of sugars and starches?
Carbohydrates
First to observe living microorganisms with a microscope
Anton van Leeuwenhoek
What organelle is unique to animal cells
Centrosomes
Lysosomes
Breaks down waste materials.
lysosomes
What is diffusion?
The movement of particles from high to low concentration.
~Everything flows from high to low~
What micropsopes do we have in our classroom?
Compound light microscope
What type of cells was the person who first used the term "cell" looking at when he made his initial observations
List two organelles unique to plant cells not found in animals cells
chloroplast, cell wall, and large central vacuole
Generates energy for the cell by breaking down glucose.
Mitochondria
What does selectively permeable mean?
A membrane allows some materials to pass but not others.
Which type of microscope provides the highest magnification?
Electron microscope
What are the three principles of cell theory
1. All living things are made of cells.
2. Cells are the basic unit of life.
3. Cells only come from other
What is the difference between prokaryotic and eukaryotic cells?
prokaryotic have no membrane bound organelles- DNA in cytoplasm, no nucleus , simple, unicellular
Eukaryotic - have a nucleus which contains DNA, more complex, may be multicellular
Organelle contains DNA
nucleus
the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's membrane.
Osmosis
What is the difference between magnification and resolution?
Magnification is the ability to make an object appear larger, while resolution is the ability to distinguish between two points.
