Hypernyms ("organelle" is a kind of...):

organ (a fully differentiated structural and functional unit in an animal that is specialized for some particular function)

Hyponyms (each of the following is a kind of "organelle"):

cilium (a hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organisms)

lysosome (an organelle found in the cytoplasm of most cells (especially in leukocytes and liver and kidney cells))

cell nucleus; karyon; nucleus (a part of the cell containing DNA and RNA and responsible for growth and reproduction)

nucleole; nucleolus (a small round body of protein in a cell nucleus; such organelles contain RNA and are involved in protein synthesis)

chondriosome; mitochondrion (an organelle containing enzymes responsible for producing energy)

centriole (one of a pair of small cylindrical cell organelles near the nucleus in animal cells; composed of nine triplet microtubules and form the asters during mitosis)

ribosome (an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell)

Holonyms ("organelle" is a part of...):
