Microscope
When looking at a specimen on your slide, you should always start with the
low power 4x
viewed dead cork cells and coined and observed tiny compartments he called cells
Robert Hooke
A cell membrane covers all cells: explain all the parts
hydrophobic tails (repel water) inside part
hydrophilic heads (love water) outside parts
Which organelle sits on the Endoplasmic Reticulum and makes proteins?
ribosomes
What are the reactants needed for photosynthesis
carbon dioxide and water
A microscope has a 4x ocular lens and a 10x objective. What is this microscope's total magnification
40
Viewed protists in lakes and observed single-celled animal-like organisms using a hand lens
leeuwenhoek
In the Gummy Bear Lab, _____ in a hypotonic solution?
the bear swells
Which organelle is approximately the size of a prokaryotic cell?
mitochondria
what are the products of cellular respiration
carbon dioxide, water and atp
When looking through your microscope, you move your slide to the right- It appears
to the left
How do prokaryotic cells differ from eukaryotic cells? (check all that apply)
t-chart
In the Onion Tissue Lab, if we add salt to the environment, identify the appearance of the cell membrane:
cell membrane shrinks
Which organelle provides energy for your brain?
mitochondria
What does the 6 indicate about each part of the cellular respiration and photosynthesis equations?
6 molecules
The part of the microscope that controls the amount of light that passes through the specimen is the
Diaphragm
stated that all plants were made of cells
schleiden
In our Gummy Bear Lab
Day 1 (As soon as we put bears in water) Identify the area of low concentration of water.
in the bear
Which structure(s) are only found ONLY in plant cells? (check all)
cell wall
chloroplast
larger vacuole
In the Starburst Lab, how many atoms were on both sides of the equation?
36 atoms
The part of the microscope that moves the stage quickly up and down and is used to focus the image under low power is the
course focus
Which scientist stated "All cells come from existing cells"
Virchow
explain when we witnessed osmosis in gummi bear lab and onion tissure lab
when the bear and onion tissue were exposed to tap water - membrane expanded
when we placed in a slat solution, water left and mebrane got smaller
Explain the whole process of how things get made and transported in the cell
nucleolus- makes ribosomes
rough ER - makes proteins
vescicles send to golgi complex
golgi complex edit proteins and make lipids
vescicles transport out of cell
explain conservation of mass regarding cellular respiration and photosynthesis
mass is neither created nor destroyed
This means that matter simply changes form rather than disappearing or appearing, and the amount of mass remains constant throughout a chemical or physical change
