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.
This basic type of animal tissue is responsible for sending electrical signals along a long structure called an axon.
What is nervous tissue?
2 word answer: DNA is in this form during interphase, and coils up into this form during prophase.
What is CHROMATIN and CHROMOSOMES?
This structure can be considered part of both the respiratory and digestive systems, as it connects the nose to the mouth.
What is the pharynx?
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 type of stem cell is a starting point for all other cells in the body, specifically before birth.
What are Embryonic Stem Cells?
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?
Prokaryotic Cells lack this key organelle
What is a nucleus?
This organelle is responsible for building proteins by grabbing Amino Acids and linking them together in the correct sequence.
What are ribosomes?
Bones are considered to be in this main tissue type in the human body.
What is connective tissue?
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?
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 type of muscle, like in the esophagus, contracts without voluntary input from the brain.
What is smooth muscle?
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?
