what would happen if we didnt have a cytoskeleton?

you would dissolve into a big soggy puddle.

if gravity was absent, teh earth would have moved away from sun...it would be dark, the plants would not grow, we would die out of cold. we maynot even be able to stand in oneplace.....

If its a matter of just some people then nothing may happen.But if everyone start to behave that way,then possibly in a long time the hands may change shape ,and so would legs,,becuase nothing in nature is "just like that".Everything has its own function and meaning.So not just the hands and legs would change positions but also ,thoughts,brains,habits,and almost everything in humanity could change.maybe we humans would call ourselves by a different name then.Earth would be downside up ;).\n(in medical terms this is an anomaly if it happens,and may be due to mutations of some kind,,,only similar and repeated mutations can change the course of life)

your body will naturally refuse anything foreign. wait it will come out on its own.

Doesn't get much simpler than this website, have fun!\n\nhttp://www.biology4kids.com/files/cell_main.html

you have microtubules, microfilaments, intermediate filements and microtrabecular system. these are vastly different from each other. do you have any more specific question?

For a cell without a cell wall, cytokinesis begins with the pinching inward of the cell membrane caused by the action of a ring of special contractile proteins called actin and myosin. The pinching inward forms a deep grove, often called the cleavage furrow. Eventually, the opposite sides of the furrow meet and the cell splits into two new daughter cells. \n\nWhereas cytokinesis in cells lacking a cell wall occurs through a pinching inward, organisms with a cell wall undergo a process through which a so-called cell plate is built from the middle of the cell outward to the membrane. Vesicles from the Golgi bodies flatten and fuse in the center of the cell, forming the cell plate, which elongates toward the cell membrane as more vesicle are added. When the cell plate reaches the cell membrane, the parent cell is effectively separated into two new daughter cells, which then proceed to build a cell wall along the cell plate.

The DNA would be unreadable and the organism would not even have a chance to develop to a 2-cell stage. Unless of course it had evolved that way, along with evolving different enzymes to deal with it and a different way of reading the DNA to make different proteins.

Many ways.\n\nPlants would have organelles specific to a plant and would be a rectangular shape with 2 nuclei during cytokinesis\n\nanimal would have no chroloplasts and would be oval because the nuclei push as far apart as possible and the animal cell is flexible, not rigged like a plant.

There are organisms in the kingdom protista that are unicellular and have no cell wall.  The only other kingdom containing organisms without a  cell wall is the animal kingdom.  I am unaware of any animal whose total body contains only 2 cells.\nIt would have to be any animal.

The first step would be a really big die-off and a collapse of civilization.  Other than slowly acquiring some negative traits, not much will happen in terms of physical evolution in the mean time.\n\nAfter this die-off, we will find ourselves in a world without the megafauna alongside of which we initially evolved.  These animals have since gone extinct.  Our food will have to be smaller and more frequent instead of big and less frequent.  As a result, I would predict a reduction in body size to more efficiently utilize resources from small to medium sized prey.

Yeah, more mitochondria for energy and more ribosomes (rough ER) to produce proteins necessary for contraction (actin + myosin).\n\nRegards,\nRyan

Because, these cells do not have the microtubule apparatus to do so. The erect a cell wall, instead. Plant cells do not have centrioles.

The legs of a fly have a primary role of helping the fly to land and lift off, and also move about a little when its not flying. If the fly would not have wings, it would be able to move futher on its legs, but the mobility would be severly restricted because the legs haven't been used in that sense before. This fact is confirmed from experimentation done in around 2003, where a genetically mutated fly which didn't grow any wings tried to move solely on its legs.

A. plant cells do not have centrioles.

It probably wouldn't feel like anything, seeing as how your body has not more nerves in parts.

if we didnt have Mitosis we wouldnt be alive there are 4 stages to rember them think PMAT
