GMM BIG ideas!

What is a cell?

• The basic unit making up all matter.

• The building block of all life.

• A gel like fluid.

• Two or more atoms bonded together.

There are two basic types of cells: prokaryotic and eukaryotic. What is the main difference between the two types of cells?

• Prokaryotic cells have a membrane around their genetic material, but eukaryotic cells do not.

• In general, eukaryotic cells are larger than prokaryotic cells.

• Eukaryotic cells have a membrane around their genetic material, but prokaryotic cells do not.

• There is no difference between these two types of cells.

Which of the following is an example of asexual reproduction?

• Pollen flowers producing seeds

• A cat having kittens.

• Zebrafish releasing sperm and eggs into a shallow pond.

• A starfish is cut in half and regenerates.

How does the number of chromosomes in a daughter cell from mitosis compare to the number of chromosomes in a parent cell?

• The daughter cell has one-half the number of chromosomes

• The daughter cell has twice the number of chromosomes

• The daughter cell has the exact same number of chromosomes

• The daughter cell has one-quarter the number of chromosomes

How does the number of chromosomes in the cells created by meiosis compare to the number of chromosomes in a parent cell?

• The gamete has one-half the number of chromosomes

• The gamete has twice the number of chromosomes

• The gamete has the exact same number of chromosomes

• The gamete has one-quarter the number of chromosomes

What part of the pistil will the pollen land on?

• Stigma

• Style

• Ovary

• Anther

Where does meiosis occur in a flower?

• Anther

• Filament

• Petal

• Sepal

Reproductive mode by which offspring arise from two parents and inherit genes from both is called:

• Asexual reproduction.

• Sexual reproduction.

• Regeneration.

• Vegetative reproduction.

The greatest degree of genetic variation would be found in offspring that result from:

• vegetative propagation.

• regeneration.

• cross pollination.

• binary fission.

Many factors affect the survival of a given species. Meiosis and fertilization are important for the survival of many species because the two processes result in:

• large numbers of gametes.

• cloning of superior offspring.

• genetic variability of offspring.

• increasingly complex multicellular organisms.
