leucoplast click to hear : leucoplast

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

mitochondrion click to hear : mitochondrion

Ovoid organelle that produces the energy necessary for cell activity.

Golgi apparatus click to hear : Golgi apparatus

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 : vacuole

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

cell membrane click to hear : cell membrane

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

starch granule click to hear : starch granule

Concentric layers of starch produced by the cell and stored for food.

lipid droplet click to hear : lipid droplet

Small sac filled with essential fatty acids that are produced by the cell and stored for food.

cytoplasm click to hear : cytoplasm

Clear gelatinous substance surrounding the various cellular structures.

nucleolus click to hear : nucleolus

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

nuclear envelope click to hear : nuclear envelope

A double-layered membrane enveloping the nucleus.

nucleus click to hear : nucleus

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

pore click to hear : pore

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

endoplasmic reticulum click to hear : endoplasmic reticulum

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

plasmodesma click to hear : plasmodesma

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

chloroplast click to hear : chloroplast

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 : ribosome

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 : cell wall

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