All plant and animal cells contain me. I direct all of the cell's activities, including reproduction. Who am i

Most of the cell's metabolic activities - that is, the sum of all the biochemical reactions that underlie life - occur in the cell cytoplasm.

The nucleus contains the cell's genetic material and control's the cell's activities.

the roots, the stem, the leaves, and the flower/fruits

protein, DNA, almost every cell in every living organism...so, basically, all of life itself.

It controls all the functions of the cell.

There is life out there.  I am an alien disguised as a human.

Every living thing does cellular respiration, so yeah plants do it too.

Plant and animal cells are alike in that they both have cell(plasma) membranes, nuclei, and vacuoles. Plant cells are different in that they also contain chloroplasts and cell walls. The vacuoles in plant cells tend to be bigger than in animal cells.

D.  The egg is a gamete, which contains half the amount of chromosomes that the body cell normally carries.

The cytoplasm containing the other cell parts.

...to live and reproduce? You need to be more specific... what kind of animal cell? In what organ? Or is it a single-celled organism? Do you mean the structure?

I believe during cytokinesis.

I'm not sure what your asking???  \nIs it the plant cell????

In animals and plants, cells are the smallest units that can be considered alive. Your body, like all human bodies, is a collection of many many cells. Nearly all cells have the same basic parts - a nucleus, which has DNA, and a cell membrane, which acts as sort of a skin for the cell, keeping insides in, and outsides out. \n\nCells are arranged together to form tissues, which in turn arrange together to form organs, which fit together to form systems (like the digestive system), which in turn all keep you as one functioning living being!\n\nMost cells in a large organism like plants and animals have specialized purposes as well - some are nerve cells, transmitting signals to and from the brain to the rest of the body, some are in your blood, carrying oxygen to the rest of the body, some form your skin, keeping you from getting infected from outside. \n\nCells have their own lifespans, and can reproduce and die.\nSometimes, a mutation happens in cells, and they don't follow their genetic instructions and might grow and reproduce abnormally -- this is what cancer is.

You have a very convuluted question.  However I would say all living things are part of the biosphere.   Bio = life.

it means that all the organelles are enclosed by a membrane

Your body makes cells by the process called mitosis.\n\nHere's a website on mitosis:\nhttp://www.cellsalive.com/mitosis.htm
