Closed system - energy can enter or leave the system but matter cannot
Open system - both matter and energy are exchanged freely between the system and the surroundings
The answer is <span>B. phagocytosis
</span>
Phagocytosis is a process in which cell ingests large fragments of matter, for example, bacteria. According to the endosymbiotic theory, a host cell ingested symbiotic bacteria (through phagocytosis). Ingested bacteria later specialised into mitochondria or chloroplasts. The evidence for this theory is that mitochondria and chloroplasts similarly to bacteria have their own circular DNA and their own transcriptional and translational machinery.
B.
Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
