Document Summary

Lack a nucleus and membrane bound organelles. Coccus type: spherical in shape, may occur singly, in chains or clusters. Bacillus type: rod shaped, may occur singly or in chains. Spirillium: spirally curved rods, may occur singly, chains or clusters. No structures that can be regarded as roots, stems or leaves. Phytoplankton are floating algae of microscopic size. Mitosis: two daughter cells are created, same number of chromosomes as parent. Meiosis: four daughter cells, each have half the number of chromosomes are parent. Same number of ploidy means the same number of chromosome sets. Multicellular organization in the form of un-branched chains of cells called a filament. Parenchymatous thallus: undifferentiated body that is usually flat and prostrate. Contains vegetative cells which possess a single nucleus and net like chloroplasts. Asexual reproduction: any cell can produce a motile zoospore, which will then divide by mitosis.

Suppose that a cell in G1 contains 10 picograms (pg) of DNA. How many picograms would you expect to find in this same cell during G2?

Note that a picogram (pg) is a measured quantity/mass. Think about how the amount of DNA changes as the cell progresses from G1 to G2.

Suppose that a single somatic cell undergoes mitosis and cytokinesis. If you compared the original parent cell in G1 with the daughter cells that are produced, which of the following statements would be true?

_____________________

The daughter cells have the same number of chromosomes and half the amount of DNA.

The daughter cells have half the amount of cytoplasm and half the amount of DNA.

The daughter cells have half the number of chromosomes and half the amount of DNA.

The daughter cells have the same number of chromosomes and the same amount of DNA.

The daughter cells have the same number of chromosomes and twice the amount of DNA.

Which statement about protists is false?

They can be single celled or multicellular

They have organelles and a nucleus

They can be autotrophs or heterotrophs

Some can have both animal-like and plant-likecharacteristics

All of the above are actually true about protists
