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.).

What term means organisms that are not closely related but still look similar?
The term that describes organisms that are not closely related but still exhibit similar features is "convergent evolution." This phenomenon occurs when different species independently evolve similar traits or adaptations in response to similar environmental pressures or challenges, despite their distinct evolutionary backgrounds. Examples include the wings of bats and birds, which serve the same function but evolved from different ancestral structures.
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.
What are some of the characteristics that scientists look at when organizing the different organisms?
pro
Why do embryos of different animals look similar?
Embryos of different animals may look similar due to shared evolutionary history. This concept is known as embryonic homology and suggests that animals with a common ancestor will display similarities during early development. Shared genetic and developmental pathways contribute to these similarities, even if the adult forms of the animals look very different.
When classifying organisms what do scientists look at?
Scientists look at various characteristics of organisms such as their physical appearance, genetic makeup, behavior, and evolutionary history to classify them into different taxa. These characteristics help scientists group similar organisms and understand their relationships and differences. The classification system used by scientists is called taxonomy.
Are all organisms that look different from different species?
Not necessarily. Organisms that look different can belong to the same species if they can interbreed and produce fertile offspring. Organisms that look similar can also belong to different species if they are reproductively isolated and cannot interbreed successfully.
Do embryos of many different vertebrates look much more similar than the adult organisms?
yes
How telescopes and microscopes different?
Microscopes have 2 convex lens and telescopes too while microscopes are used to look at cells and microscopic organisms.
Do cells in many-celled organisms all look the same?
no
Why do animal cells look different then plant cells?
they are different because they are
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.
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.
Do french and Italian Renaissance paintings look similar or different?
To a trained eye they look different.
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.
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 is the definition of similar in geometry?
similar to look the same but have a different size or measurement.
