What are two observations a scientist could make about the leaf cells and chloroplasts?
Leaf cells contain chloroplasts. Photosynthesis occurs in the chloroplasts as they retain energy from the sun. Chloroplasts contain chlorophyll, which make leaves appear green.
Can Chloroplasts can be found in both plant and animal cells?
Chloroplasts are generally only found in plant cells, although there may be some circumstances in which they could be found in animal cells, I doubt it.
Which structures could most likely be observed in cells in the low power field of a compound light microscope?
Cell walls and chloroplasts
A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the organelles Organelles in one of the heavier fractions could produce ATP in the light while organelles?
Chloroplasts and mitochondria. *on masteringbio, be sure to choose the above, and not "mitochondria and chloroplasts"
Sense not to be used for laboratory observations?
All senses can be used for laboratory observations, except taste. If you are to smell, you should wave your hand over the solution to redirect the smell towards your nose and not SNIFF it in. Using taste for a laboratory observation is very dangerous, and could be fatal.

Why is observations important to scientists?
Observation helps scientists gather an collect data, which without, their experiment(s) could not exist
Why do scientists use tools when they make observations?
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
How is a theory and a observation related?
Scientists make observations about the natural world through experiments and try to explain the phenomena that they observe. Scientists then attempt to explain the occurence of all of these observations in an overarching theory. For example, an observation would be seeing an apple fall to the ground and making measurements. The next step would be taking all of these observations which could include things such as the movement of planets and other cosmic bodies to form the theory of gravity which attempts to explain these observations.
What are qualative observations?
Qualitative observations could also be called qualitative data, and would be data not related to exact numbers. Such observations could be warmth, flavor, gender, or yes-no answers to questions.
What food item could you use for a chloroplasts?
Peas
If you could add chloroplasts to animal cells how would it change their behavior?
They would be able to photosynthesise, which they are currently unable to do because they do not possess chloroplasts.
Why have scientists revised the a atomic model many times?
they could discover a new atom and it would change
What could be a possible function of a plant cell that has a lot of chloroplasts?
Chloroplasts are used for photosynthesis. Thus, these cells could be involved heavily is carbon fixation (making glucose from c02 + h2o, Calvin cycle). Probably leaf cells.
How would you decide if a cell was animal plant prokaryotic?
If a cell does not have a nucleus, then it is a prokaryote. If a eukaryotic cell has chloroplasts, then it is a plant or algal cell. If a cell has a nucleus but no chloroplasts, then it could be an animal cell.
