What else can I help you with?
What are two observations scientists could make about the leafcells and chloroplasts shown?
Scientists could observe that the leaf cells have a large number of chloroplasts, indicating their role in photosynthesis. Additionally, they could note the green color of the chloroplasts due to the presence of chlorophyll, the pigment responsible for capturing light energy.
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.
What would be the impact on the environment if an artificial virus that attacked and destroyed chloroplasts in plant cells was accidentally released by a research company?
If an artificial virus that targeted and destroyed chloroplasts in plant cells was accidentally released into the environment, the impact would be devastating. Chloroplasts are essential for photosynthesis, the process by which plants convert sunlight into energy. Without chloroplasts, plants would not be able to produce food or oxygen, leading to widespread plant death and disruption of the entire ecosystem. This would result in a significant decrease in oxygen levels, loss of biodiversity, and ultimately, a collapse of the food chain.
Which scientist first saw cork cells in 1662?
Robert Hooke was the first scientist to observe cork cells in 1662 using a simple microscope he had built. He coined the term "cell" to describe the box-like structures he saw, reminiscent of small rooms monks lived in, known as cells.
What are the 3 organelles in a plant cell that are not in an animal cell?
Good question. My class acutally finished a lesson like this. I know that in a plant cell, there is a cell wall, and chloroplasts that are not in an animal cell. Although I'm not sure of a third. Hope I could help!

Why is careful obersavation important to being a scientist?
A scientist may create an hypothesis on the basis of their observations. If their observations are carelessly made or recorded then any hypotheses they offer will be inaccurate reflections of nature. A scientist may alternatively collect observations to test an hypothesis. If these observations are carelessly made or recorded then the conclusions that the scientist makes about the hypothesis could very well be incorrect. At the very least the conclusions they draw would not be based on sound evidence (because the observations are unsound).
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.
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.
What structure could you see in the Elodea cells?
In Elodea cells, you could see structures such as the cell wall, cell membrane, chloroplasts (containing chlorophyll for photosynthesis), and a central vacuole. These structures are typical of plant cells and contribute to their function in photosynthesis and support.
How do you know the students in the above study are acting as scientist?
Students could be seen to be acting as scientist if they are following the scientific method - Make observations, postulate a hypothesis, and form and complete experiments or further observations to confirm or refute that hypothesis.
What cell has small green dots?
Cells with small green dots could be chloroplasts in plant cells, or mitochondria in animal cells. Chloroplasts contain chlorophyll and are responsible for photosynthesis, while mitochondria are the powerhouse of the cell involved in producing energy.
Which organelle is present in the cells of a bean plant but not in the cells of a mouse?
Centriole
Why is it important for scientist to record their observations?
i think it is because then they could see their notes again later and see if anything has changed. but i am not sure.
What was the impact of Leeuwenhoek's contribution?
Antony van Leeuwenhoek (1632-1723) was a Dutch scientist. He designed microscopes that could magnify up to 200 times. These enabled him to discover bacteria, protists, sperm cells, blood cells and many more microscopic features of living cells or micro-organisms. His discoveries were important milestones in the field of biology. He did not invent the microscope, but his inquiring mind, astute observations and his keen mind were all the more impressive as he was not educated as a scientist.
Why are scientist tools important?
A scientist needs tools in order to conduct controlled experiments for gathering data. Without the proper materials, a scientist could not make objective observations on their field of research, and so their findings would be meaningless. Also, a scientist needs a large sample size in order to account for all variables that could influence the experiment.
