Microscope Pioneers & Tech
This term refers to how clear an image is under a microscope, allowing you to see finer details inside a cell.
What is Resolution?
According to the Cell Theory, all new cells are produced from these.
What are pre-existing/existing cells?
This organelle is known as the powerhouse of the cell because it converts energy stored in food into usable cellular energy (ATP).
What is the Mitochondrion (or Mitochondria)?
In living organisms, this level of organization is defined as a group of similar cells working together to perform a specific job.
What is a Tissue?
Drops of food coloring spreading evenly throughout a beaker of water without stirring occurs due to this passive transport process.
What is Diffusion?
These two early scientists used early microscopes to view dead plant cells and tiny microscopic organisms swimming in water.
Who are Leeuwenhoek and Hooke?
These two scientists concluded after many observations that all plants and animals are made of cells.
Who are Schleiden and Schwann?
This flexible outer structure controls what enters and exits the cell, such as water, salt, and nutrients.
What is the Cell Membrane?
These two cell structures are found in plant cells, but are completely absent in animal cells.
What are the Cell Wall and Chloroplasts?
The movement of water across a semipermeable membrane from an area of higher water concentration to lower water concentration is called this.
What is Osmosis?
This advanced type of microscope allows scientists to view cells and cellular structure in extremely great detail.
What is an electron microscope?
Regardless of its specialized job, all living cells must perform these three essential functions to survive.
What are obtaining energy, bringing in nutrients/water, and getting rid of wastes?
A plant leaf infected with the mosaic virus develops light green patches that cannot capture sunlight because this specific organelle is damaged.
What is the Chloroplast?
Nerve cells, red blood cells, and muscle cells in the same animal look completely different under a microscope for this main reason.
What is cell specialization (they are specialized to perform different functions)?
An amoeba catches prey by extending its cell membrane outward to wrap around a food particle and pull it inside using this active process.
What is Endocytosis?
Switching a compound light microscope from a 4x objective lens to a 40x objective lens causes these two image properties to increase.
What are magnification and resolution?
If you look inside a cell with a super-powerful electron microscope, you will not find smaller cells inside because of this core Cell Theory principle.
What is "the cell is the basic unit of structure and function in living things" (or basic unit of life)?
Patients suffering from Cystic Fibrosis have difficulty regulating the movement of salt and water into and out of their cells because this organelle is affected.
What is the Cell Membrane?
When several different types of tissues work together in a multicellular organism to perform a major body job, they form this level of organization.
What is an Organ?
Cholera bacteria release toxic proteins outside their cells by packaging them into vesicles that fuse with the membrane in this process.
What is Exocytosis?
Before microscopes and improved technology were invented, this is how much scientists understood about the internal structure of living things.
What is very little/almost nothing?
This statement correctly identifies which types of living organisms are composed of cells.
What is all living organisms (plants, animals, and bacteria)?
Joe constantly feels exhausted and short of breath because his body cannot convert food into usable energy. This specific organelle is failing to perform its job.
What are the Mitochondria?
An oak tree is able to grow tall and sturdy on steep hillsides without collapsing because its cells have this rigid outer boundary.
What is the Cell Wall?
Pumping chloride ions outside a cell membrane where a high concentration already exists requires the cell to spend cellular energy, making it this type of transport.
What is Active Transport?
