Let's take for example, a simple fruit plant. What do you do when you are thirsty? You go to the kitchen and get a glass of water. Right? What do you do when you are hungry? You grab some food and eat. Well, plants can't move nor they can provide for themselves. So when they need water because it hasn't rain or there is a drought, they have other defense mechanisms to counterarrest these factors. By changing the color of their leaves, or by growing deeper roots, or perhaps they send signals that will make them stop growing. All these factors must be considered when we ask ourselves this questions. I hope that this will help students think more and brainstorm a little of why we only have 46 chomosomes. Perhaps in the future we will have less after we go through some mutation. Remember that mutation is a process of evolution.

∙ 14y agoSome organisms contain 0 chromosomes, for example prokaryotes whose DNA is formed into plasmids instead of chromosomes. Even among animals, chromosome numbers vary widely, for example 8 in the fruit fly and 132 in the kingfisher.

Do chromosomes contain mitochondria that determine which trait an organism will have?
No.In some cells, mitochondria contain small chromosomes. Mitochondria have circular DNA molecules.Not advanced as chromosomes
What do bacteria have in common with the cells of other living organisms?
They have ribosomes.They contain cytoplasm. Some things bacteria have in common with cells of other living organisms is they both have chromosomes, they both have organelles and a nucleus, and are alive. they have a cell membrane
How can you tell if a cell has chlorophyll?
if organisms contain green color they contain chlorophyll. but some organisms like cyanobacteria they contain chlorophyll but also contain blue pigment. So they look like bluish and also some time redish. The organisms who contain chlorophyll they are autrophic and prepare their own food but some time also become parasitic.
Is the number of gametes twice the number of chromosomes found in the body cells?
Gametes are cells, in humans they contain 23 chromosomes. Body Cells (Properly Called: Somatic Cells) in humans contain 46 chromosomes (2 sets of 23). Some differences or problems can cause this number to change in specific humans, gametes, and somatic cells. Muscle cells may have hundreds of chromosomes, red blood cells have none.
How many long chromosomes are present in each new cell?
It all depends on the type of organism on many chromosomes are present in each cell. By regular cell division each new cell will have the same number as the original cell. Some organisms have many more chromosomes than humans do and some have many less chromosomes.
How many chromosomes do they contain?
Bacteria contain one circular chromosome (and several tiny circular plasmids), some slime molds contain hundreds of thousands of linear chromosomes. Other organisms contain various numbers of chromosomes depending on the species.

Why can egg cells from a horse only contain an x chromosomes?
Females only contain X in their sex chromosomes. That s why females have XX and males XY. When females form gametes, they only can form them with a X chromosome. This however have some exceptions, for example, chicken females are XY whereas males are the one with XX.
What does haploide mean?
"Haploid" refers to the number of chromosomes in a gamete.You may talk of a haploid number, haploid nucleus, haploid cell, or even a haploid organism, which is an animal or plant whose body cells contain the haploid number of chromosomes. Examples of haploid organisms are male honey bees and the leafy parts of mosses.The haploid number is often the number of chromosomes in a single set (n); this is true of us humans, for example. Our gametes contain one set of chromosomes (n = 23), and our somatic (body) cells two sets (2n = 46).However, some organisms have more sets; some wheat is tetraploid (4n) and its gametes are therefore 2n. In these cases the number of chromosomes in a single set (n) may be called monoploid.
Does the nucleus of the plant Cell contain chromosomes?
yes nucleus contains cromosomes in special cases known as closed mitosis in which within the nucleus mitosis accours and after the completion of mitosis only nnucleus divides.this pattern of mitosis is also called endo mitosis.it occurs in some lower organisms.
How can you tell if a cell has chlorophyll?
if organisms contain green color they contain chlorophyll. but some organisms like cyanobacteria they contain chlorophyll but also contain blue pigment. So they look like bluish and also some time redish. The organisms who contain chlorophyll they are autrophic and prepare their own food but some time also become parasitic.
How many chromosomes do protists have?
Parameciums are unicellular organisms, hence they only have one cell.
After fertilization how is the cell similar to and diffferent from the original cell?
Do you mean the similarities and differences between the new set of chromosomes and the parents' chromosomes? Or do you mean to ask about the comparison of the egg before/after fertilization?Only egg cells are fertilized.After fertilization, the egg should contain a complete set of chromosomes for the specific animal.If you meant the difference between the new set of chromosomes and the parents' individual chromosomes, the new set will generally contain the dominant genes of each gene type, and a few (generally minor) mutations. These mutations are what keep the organisms from slowly running out of non-relatives to breed with, in which case they would have had some severe genetic problems, as they would be amplified (which is the major problem of in-breeding).
How many chromosomes are in a genome?
23 i think -- There's no such thing as "a DNA. But it works the other way around: DNA doesn't contain chromosomes, but chromosomes contain DNA. A person has 23 chromosome pairs: 46 chromosomes. One (pair) of which decides gender. Some people aren't perfect and have 47 chromosomes. Maybe other 'combinations' exist too.
Is the number of gametes twice the number of chromosomes found in the body cells?
Gametes are cells, in humans they contain 23 chromosomes. Body Cells (Properly Called: Somatic Cells) in humans contain 46 chromosomes (2 sets of 23). Some differences or problems can cause this number to change in specific humans, gametes, and somatic cells. Muscle cells may have hundreds of chromosomes, red blood cells have none.
Do most organisms contain inorganic compounds and organic compounds?
All the organisms mostly contain organic compounds. Organic compounds are made of elements C and H. Some can contain N,P,S too.
