five-kingdom system
a convenient way to classify living organisms
kingdom Monera
contains bacteria, which are microscopic organisms. (only kingdom with prokaryotic cells)
kingdom Protista
has two subkingdoms: algae (one or many eukaryotic cells) and protozoa (one eukaryotic cell)
kingdom Fungi
contains organisms like mushrooms, molds (many eukaryotic cells) and yeast (one eukaryotic cell).
kingdom Animalia
contains animals (many eukaryotic cells)
kingdom Plantae
contains plants (many eukaryotic cells)
prokaryotic cell
a cell that has NO distinct, membrane-bounded organelles (such as a nucleus)
eukaryotic cell
a cell with distinct, membrane-bounded organelles (such as a nucleus)
algae
(1) have NO specialized structures that perform individual tasks. (2) have chloroplasts. (3) can make their own food.
plants
(1) have specialized structures like roots, stems, leaves, that each perform individual tasks. (2) have cell walls, chloroplasts, and have a large central vacuole in each cell. (3) can make their own food.
