Microscopes and Cell Theory
This would be the total power of a microscope with a 5x ocular lens and a 50x objective lens.
What is 250x?
This organelle is responsible for transporting materials into and out of the cell. They are commonly produced by the Golgi apparatus.
Water (a solvent) enters and exits cells via a type of passive transport called this.
What is osmosis?
2 word answer: DNA is in this form during interphase, and coils up into this form during prophase.
What is CHROMATIN and CHROMOSOMES?
This basic type of animal tissue is responsible for sending electrical signals along a long structure called an axon.
What is Nervous tissue (Neurons acceptable)?
A cell is measured to be 52 micrometers and is centred on a microscope with a field diameter of 400 micrometers. About this many cells can fit across the field of view.
What is 7 or 8 cells?
This organelle is Mr. D'Angelo's FAVOURITE and is responsible for producing energy by performing cellular respiration across its many membranes.
What is the Mitochondria?
This molecule on the cell membrane is responsible for recognizing signals and invasive molecules before they can enter the cell.
What are carbohydrates?
In this phase of the cell cycle, a cell plate forms along the midline of a plant cell.
What is cytokinesis?
In the respiratory system, this structure is responsible for contracting to allow the chest cavity to get bigger, so air can rush into the lungs.
What is the diaphragm?
In 1858, this scientists discovered that all cells must come from pre-existing cells.
Who is Virchow?
This organelle is responsible for building proteins by grabbing Amino Acids and linking them together in the correct sequence.
What are ribosomes?
A cell is placed in a hypotonic solution. Water will move in this direction.
What is into the cell?
Humans have this many chromosomes in each cell.
What is 46 (or 23 pairs)?
Chemical digestion first takes place in this location.
What is the mouth?
Fungi and protists are unicellular and are classified as this type of cell.
What are EUKARYOTES?
This organelle is responsible for regulating the amount of water inside a cell, particularly a plant cell.
What is the vacuole?
This process allows cells to move larger particles, like neurotransmitters, out past the cell membrane.
What is exocytosis?
In this phase of the cell cycle, the nucleus reforms.
What is telophase?
In the Circulatory system, blood travels through the left ventricle and then passes directly into this structure.
What is aorta?
The Liver is responsible for producing this fat-digesting substance, but the Gall Bladder stores it.
What is bile?
