Small colorless structure that produces and stores starch, the vegetable’s food.

mitochondrion click to hear

Ovoid organelle that produces the energy necessary for cell activity.

Golgi apparatus click to hear

Organelle composed of a series of pockets that receive proteins produced by the ribosomes and either transport them outside the cell or to other organelles.

vacuole click to hear

Spherical cavity containing water, waste and various substances required by the cell.

cell membrane click to hear

Casing that covers the cell’s cytoplasm; it acts as a filter, controlling the passage of certain substances in and out of the cell.

Small spherical body located inside the nucleus, within which the ribosomes, or protein-synthesizing structures, are produced.

nuclear envelope click to hear

A double-layered membrane enveloping the nucleus.

nucleus click to hear

Organelle containing a cell’s genes and controlling its activities.

pore click to hear

Perforations in the nuclear envelope allowing for exchanges between the cytoplasm and the nucleus.

endoplasmic reticulum click to hear

Interconnecting tubes allowing substances to be transported within the cell or between the cell and its exterior environment.

plasmodesma click to hear

Perforations in the membranes allowing two adjacent cells to exchange cytoplasm.

chloroplast click to hear

Small structure, containing a green pigment called chlorophyll, which absorbs solar energy and uses it to produce glucose, the vegetable’s food.

ribosome click to hear

Small structure, occasionally attached to the endoplasmic reticulum; it generates proteins essential to the formation and functioning of living things.

cell wall click to hear

Stiff exterior surface of the cytoplasmic membrane that gives the cell its shape.
