An eyepiece graticule is how we measure the size of objects using an electron microscope
The scale of an eyepiece graticule is etched onto a ❌ placed in the eyepiece of a microscope. The scale is typically ❌ long and divided into ❌ sub-divisions.
What's a good idea to do once you've calibrated the graticule?
Never change the graticule
Mark it down for future use
Keep the same microscope for each calibration
What are the features of a nucleus?
Nuclear envelope
Proteins
Nuclear pores
Nucleoplasm
Chromosomes
Nucleolus
Cell wall
Vacuole
The function of the nucleus is to act as the ❌ of the cell through the production of ❌ hence protein synthesis, retain the ❌ of the cell in the form of DNA and chromosomes and manufacture ❌.
What are the features of mitochondria?
Double membrane
Stroma
Matrix
Ribosomes
Cristae
Mitochondria is the site of anerobic aerobic( anerobic, aerobic ) respiration. They're responsible for the production of the energy-carrier molecule, ATP ADP Carrier-protein Sodium ions Protein channel( ATP, ADP, Carrier-protein, Sodium ions, Protein channel ), from respiratory substances such as glucose.
What are the main features of chloroplasts?
Chloroplast envelope
Grana
Grains
The chloroplast is adapted to their function of harvesting sunlight and carrying out photosynthesis by the granal membranes providing a ❌ for the attachment of chlorophyll, electron carriers and enzymes that carry out the ❌ stage of photosynthesis, the fluid of the stroma possesses all the ❌ needed to make sugars in the second stage of photosynthesis and chloroplasts contain both DNA and ribosomes to quickly and easily manufacture some ❌ needed for photosynthesis.
