Key Vocabulary

The pollen-producing tip of a stamen.

One of the threadlike "packages" of genes and other DNA in the nucleus of a cell. In reproduction, offspring receive half of their chromosomes from the male parent and half from the female parent.

In plants, the union of parental chromosomes (found in the pollen and the eggs) to produce a seedling.

The scientific study of DNA, the genes, or the chromosomes - the physical structures that guide development and are the basis of inheritance.

The functional and physical unit of heredity passed from parent to offspring. Genes are pieces of DNA, and most genes contain the information for making a specific protein.

The sprouting of a plant seed.

In flowering plants, the part of the flower which encloses the ovules. When the ovary matures, it becomes the fruit.

In plants, the structure which contains the eggs and gives rise to the seed.

One of the outer appendages of a flower, located between the outer sepals and the stamens. Petals often display bright colors that serve to attract pollinators.

The seed-bearing, "female" part of a flowering plant.

The male sex cells of a flowering plant produced by the anther; pollen usually appears as a fine dust.

The process of transferring the pollen from its place of production to the place where the egg cell is produced. This may be accomplished by the use of wind, water, insects, birds, bats, or other means. Pollination is usually followed by fertilization.

The outermost structure of a flower which serves to enclose and protect the flower bud before it has bloomed.

The "male" part of the flower, the tip of which produces pollen and is called the anther.

Seasonal schedules

MPSC offers seasonal schedules of Science 360 shows to the public. Follow this link to see the current schedule of public shows at MPSC.

Please note that seasonal schedules change four times each year (spring, summer, fall and holiday), and some shows are not offered during every schedule.

School shows

In addition to its public shows, MPSC offers shows during the week especially for school classes and other field trip groups. These school shows do not appear on the seasonal schedule but do appear on MPSC's daily calendar.

If seats are available, the public may purchase tickets to school shows.

However, school groups with reserved seating have first priority on any remaining seats (for example, if extra chaperons attend), so MPSC cannot guarantee that public seats will be available for school shows.
