DNA in loops
no membrane bound organells
stem cells clone themselves into specialist cells the body requires
nerve cells have lots of mitochondria schwarn cells dendrites attach them selves to other cells . They have chemical transmitters
sperm cells have Exposed tip. half DNA so new cell gets whole. Mitochondria provides energy to swim. Tail is used to swim
phloem cells' walls break down to allow water to move freely. The companion cells provide energy to dissolve food.
muscle Cells store glycogen . They have special protein which slides over to contract mitochondria to transfer energy for chemical reactions.
if you cut yourself your stem cells will create skin cells
actual size x magnification size = image size
electron microscopes fire electrons so you can get a 3D image. it is used so you can see Small cells and membrane bound organelles
membrane bound organells
DNA inside nucleas
chlrophlasts (inside some)
