the two organelles found only in plants include chloroplasts and cell wall.
Explanation:
cell wall is the outermost boundary in most plant cells while animal cells lack it .but the cell wall of plant cells is different from that of prokaryotic cell wall, both in structure and chemical composition.CELL WALL prevents the osmotic lysis of plants and provides them a definite shape. another organelle found only in plants is the CHLOROPLAST. choloroplasts are the type of plastids which are not found in animal cells .choloroplast contain a green pigment called chlorophyll which halp in PHOTOSYNTHESIS. in adition to these plants also contain GLYOXYSOMES and a large "centeral" vacuole which is present in animal cells but it is of small size and pushed towards periphery due to nucleus.
Parasitism is symbiotic relationship where an organisms lives in or on it's host thereby feeding and causing harm on it host. Examples of such relationship is parasites like roundworm, ticks, fleas that feed on humans and cause harm.
