Small colorless structure that produces and stores starch, the vegetable’s food.
mitochondrion
Ovoid organelle that produces the energy necessary for cell activity.
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
Spherical cavity containing water, waste and various substances required by the cell.
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
Concentric layers of starch produced by the cell and stored for food.
lipid droplet
Small sac filled with essential fatty acids that are produced by the cell and stored for food.
cytoplasm
Clear gelatinous substance surrounding the various cellular structures.
nucleolus
Small spherical body located inside the nucleus, within which the ribosomes, or protein-synthesizing structures, are produced.
nuclear envelope
A double-layered membrane enveloping the nucleus.
nucleus
Organelle containing a cell’s genes and controlling its activities.
pore
Perforations in the nuclear envelope allowing for exchanges between the cytoplasm and the nucleus.
endoplasmic reticulum
Interconnecting tubes allowing substances to be transported within the cell or between the cell and its exterior environment.
plasmodesma
Perforations in the membranes allowing two adjacent cells to exchange cytoplasm.
chloroplast
Small structure, containing a green pigment called chlorophyll, which absorbs solar energy and uses it to produce glucose, the vegetable’s food.
ribosome
Small structure, occasionally attached to the endoplasmic reticulum; it generates proteins essential to the formation and functioning of living things.
cell wall
Stiff exterior surface of the cytoplasmic membrane that gives the cell its shape.
