Some Plant-Like Protist Details • Many plant-like protists are free living aquatic organisms. Together with certain photosynthetic bacteria, they make up the group called phytoplankton. • Phytoplankton are the basis of the aquatic food chain, and are necessary for ecological stability in the ocean. • Some plant-like protists are unicellular and some are multicellular, such as seaweeds.
Plant-like Protists Continued... • Other plant-like protists live in colonies – they exist as unicellular organisms, but always travel together in groups. • Algae are plant-like protists. • Remember that our example from previous classes of plant-like protists were euglena. That is the only plant-like protist you will be expected to remember structurally.
Important Forms of Cells Diploid Cells (2n) • Diploid cells contain a full set of chromosomes. • All the other cells in the human body besides sperm and egg are diploid. Haploid Cells (1n) • Haploid cells contain half the chromosomes of a complete cell. Also called gametes. • Examples include sperm and eggs in humans.
