Currently only stem cells for diseases of the blood are available. Others are in testing mode.
Isn't it obvious? Cells are places in prisons where they keep prisoners, or people that have done something wrong, and tissues are a substance of material that you blow your nose in when you have a cold.I would have thought that obvious to everyone!Cells are a jelly-like substance inside us humans. They are the CORE of us humans. When we are a nucleas inside our mothers womb, we are made up of only stem cells. Now, stem cells are extremly special, as they can change into any other cell in your body. So, what happens is, when you start developing, some of these cells change into brains cells, some into blood cells, or maybe skin cells, and if you're a boy, sperm cells also. We have millions of cells inside us.As for tissues, it's easy to understand as long as you understand the cells. Tissues are a group of the same cells. Once again, we have millions of TISSUES inside us. These are extremly important, as without these, our whole body wouldn't work.I know you didn't ask for more than that, but I'll give you more...Onto Organs: Organs can't work alone, can they? Your heart wouldn't work without the blood cells, (blood), as the heart would have nothing to pump around. But Organs also can't work without other Organs. Taking the heart for another example, the heart wouldn't work without the lungs, because lungs help us breathe, helping the heart pump. The brain is also an Organ, and without it, NONE of us would work, as when the brain shuts down, so does our WHOLE body.So, to make our body work, we have to have Organ Systems. Like the digestive system. That is a group of Organs working together to digest our food.I hope I helped you. And remember, I'm only eleven! I would like to thank Mr Shufflebotham for teaching me this, and I want to say HI to Molly F, Jack G, George S, Jack D, Oscar B, and of course, ME! Hehe!
Actively dividing cells of the epidermis stain darkly with hematoxylin because it binds to the nucleic acids (DNA and RNA) found in the nucleus, which are abundant in dividing cells. This allows for easy visualization of these cells under a microscope.
err... maybe because the structure of the organs of a frog is most likely the structure & position of organs in a human's body... and frogs are easy to get or buy... and many species are not endangered! :) hopin' this can help!
Adjacent cells are cells that are next to each other in a spreadsheet, typically arranged in rows and columns. These cells are connected and can interact with each other, making it easy to perform calculations and data analysis.
Robert Hooke chose cork for examining cells because it is a plant tissue that is composed of dead cells with distinctive cell walls that are easy to see under a microscope. By examining cork cells, Hooke was able to observe their structure and accurately describe them as "cells".

Stem cells
For multicellular organisms (like us) cell division allows an organism to grow and develop from a single cell to trillions of cells, to repair and replace cells worn out and used up by everyday life, and in some cases, to make specialized cells for reproduction. or, to make it more easy to understand, in multicellular living things, cell division is required for tissue repair and growth. :)
