In an organism, it is the genetic information located in the nucleus that determines everything about the organism. However, the organelles in each cell have basic functions that are important in the survival of just about any organism. Of course, plants and animals vary slightly in cell organelles due to different functions (plants have cell walls, chloroplasts, etc.).

How can scientists know when cells are cancerous?
Because they appear mutated compared to other "normal" cells. Multiple mutations in one cell leads to cancer. Some look similar to normal cells, most don't, google for images of different types of cancer cells
What do the four daughter cells look like compared to the original zygote?
They look similar to the Zygote but not identical.
Why do nerve cells and muscle cells look different?
Different cells have different appearences because they have different functions. A good rule of thumb is the "form follows function" rule.
Why do plant cells have cell walls and animal cells do not?
Well there is no real reason for it, its just how the different organisms evolved.Well there is no real reason for it, its just how the different organisms evolved.
What are some of the characteristics that scientists look at when organizing the different organisms?
pro
Do embryos of many different vertebrates look much more similar than the adult organisms?
yes
Do cells in many-celled organisms all look the same?
no
How telescopes and microscopes different?
Microscopes have 2 convex lens and telescopes too while microscopes are used to look at cells and microscopic organisms.
Are all organisms that look different from different species?
no.
Why do animal cells look different then plant cells?
they are different because they are
Are cells alike?
No, they are not. They have similar features, but some have different jobs which they have features unlike other cells to fulfil their different job
What does 'cells in multi cellular organisms often specialize' mean?
When a body is made out (eg an amoeba) of one or just a few cells (eg a sponge) then these cells tend to look the same and do similar things. However as a body becomes made out of millions of cells (eg a dog), then the cells, although they are come from the one original egg cell, differentiate. Some become bone cells, others skin cells, others nerve cells - the cells specialize in multi-cellular organisms to make the organism more efficient.
Do many-celled orgnisms look alike?
Many-celled organisms do not look a like. Their appearance will vary based on what cells they are made up of. They also often have a different structure than each other.
How are prokaryotic cells and eukaryotic cells similar?
Both are cells. Both contain ribosomes, DNA......
What should you look for when considering whether structures from two kind of organisms are homologous?
The structures should have similar anatomy in the two organisms.
