The cells of plants and animals are similar, except for a few different structures. Which structures are only found in plant cel
Leviafan [203]

Answer:

large central vacuole

cell wall

Explanation:

Let me clear some things up for you. There are two types of cells - Prokaryotes and Eukaryotes. The principle difference between these types of cells are the structure of their genome. In case of prokaryotes, the genomic matter do not have a defined structure, it just kind of floats around in the protoplasm. But in the eukaryotes, the genome is more structured, have all kinds of proteins associated with them, and is surrounded by a two layered sack called the nuclear membrane. Both plant and animal cells have these feature of structured nucleus, therefore, they are both eukaryotes.

Now for the difference between plant and animal cells. the features you mentioned are unique about plant cells, but do not rule them out from being eukaryotes, as the 'true' structure of the nucleus is still there. Cell walls are necessary for the plant cells because plants do not posses an endoskeleton like most of the animals do. The cell wall makes the whole plant rigid so they don't fall apart or appear like a blob. Chloroplast is where photosynthesis happens, so it should most definitely be in a plant cell. Animals don't do photosynthesis so they don't have chloroplasts. Vacuoles are also present in animal cells, but they are much smaller, greater in number, and are known as lysosomes. Functionally they are virtually the same.

Is vitamin c prevents sore throat testable by scientific inquiry
sergey [27]
There is not enough evidence to support that <span>vitamin C aid in sore throat. But there is no harm too.

In the medical field, every treatment should be supported by evidence. This practice called evidence-based medicine. There is so much drug claim that actually wasn't supported by research and might be potentially doing more harm than benefit. Theory or argument about why it should work is not enough, you need to do a research to find the truth.</span>

Answer: Ribose is synthesized from glucose and other monosaccharide molecules in living cells by a process known as pentose phosphate pathway. The pentose phosphate pathway is a series of chemical reactions taking place in the cytosol of cells.
