Membrane enclosed organelles
Organs are made up of small cells instead of large cells to allow the organs to be not easily harmed. This way if one cell dies or is attacked then the organ will not be damaged. If the cell was larger then the organ might not be able to recover.
Mitochondria or ribosome
They have ribosomes.They contain cytoplasm.
Some things bacteria have in common with cells of other living organisms is they both have chromosomes, they both have organelles and a nucleus, and are alive.
they have a cell membrane
Eukaryotic cells contain organelles that are enclosed in membranes
Passive
Spontaneous generation does not happen.
more volume decreases the surface area of the cell thus making the distance of transporting nutrients in and out of the cell less. so more volume is better
They all Contain DNA
It is very selective about what it allows to pass through.
