Bacteria don't eat but they produce their food by the use of light through photosynthesis or the use of chemical substances for energy, chemosynthesis.
They do not eat blood cells! Where did you get that idea? They reproduce by entering blood cells and then entering one after another.
White blood cells engulfing and destroying disease-causing bacteria is an example of immunity.
White Blood Cells (WBC) ;D
I think all animals have at least some cells with nuclei. But for sure, red blood cells do not have a nucleus. That's why when people test for DNA from blood they have isolate the red and white blood cells.
A blood clot forms over a cut to stop bleeding and to keep bacteria from entering the wound. Bacteria-fighting cells then come to the area to kill bacteria.
White Blood Cells
You Must mean White blood cells. White blood cells kill bacteria by first engulfing them, this process i believe is called phagocytocis. They literally eat the bacteria and digest it.
they eat them
by engulfing the bacteria
For the most part, they "repel infection", but eat bacteria in doing so.
lyse=to break lysosome is an enzyme present in white blood cells or in leucocytes which break the cell wall of bacteria
because white blood cells are cells that keep your body healthy they eat up all the bacteria in your body so they get bigger and form more to help eat all the bacteria because there is more bacteria in your body when you are sick
they "engulf" the bacteria
antibody
Bacteria can attack and kill cells. White blood cells can kill bacteria.
White blood cells eat bacteria because without white blood cells bacteria would be in our body all the time and we would always be poorly. Also the scientific term for eating when on the subject of white blood cells is engulf, therefore when you mention this word in your work or in a assessment you may get extra marks. Back to the origional question why do white blood cells eat bacteria, i believe that i was god who made us an programmed our boy to do intresting functions to prevent us from becomiong ill.
your white and red blood cells work to keep you healthy. for example you got a cut then your red and white blood cells would swarm to that area and try their hardest to get rid of bacteria and other harmful things. So yes, white blood cells do eat invaders although I'm not sure that eat is the technical term.
No. They just "eat" them just as you would if you ate a sandwich.
