parts of the cell Flashcards
Nucleus
contains genetic information and control center
Nuclear membrane
protects the Nucleus and lets chemicals that the nucleus want out, out.
Vacuole
Stores glucose/sugar
Mitochondria
Breaks out energy
cytoplasm
is a jello that gives cells form
lysosome
breaks down worm/old parts and makes enzymes
Ribosomes
takes protein to structure and function
Endoplasmic redicuscam/ ER
Transportation
cell membrane
Protects the cell and transports it.
Golgi apparatus
1 brings in items
2 packages them
3 ships them out
cell wall
protects the cell however it doesn’t allow for movement
Plant Vacuole
Much bigger and stores glucose/sugar
chloroplastic
absorbs sunlight
how to handle a microscope
Hold it by the base and grab it by the neck (one hand one neck the other hand under the base).
Know how to focus a microscope
Power–Focus on low power with coarse adjustment then fine tune with fine adjustment
Power– Focus on medium power w/fine adjustment
Power– focus on high power w/ fine adjustment
What cell organelle (part) allows substances to pass in and out?
The cell membrane– water is allowed in and out freely with no energy used.
Cells do not look like the average cell, they specialize-can change shape and structure
Depends on what type of cell it is (muscle, bone, nerve, etc…)
Cell membranes found in animals, plants, protists, fungi and bacteria
Cell walls are found in plant cells, some protist, some bacteria
Nucleus of cell found in animals, plants, protists, and fungi
Bacteria– no nucleus (no time to make one splits every 20-30 minutes) Genetic material– scattered all around the bacteria.
Nucleus contains DNA (genetic material)
DNA is the blueprint of your cell which its your blueprint
When using high power on a microscope, what is the tradeoff?
Good part you see the specimen larger
Trade-off It is blurry only see part of the specimen
