| The leaflike structure of a seaweed that provides most of the surface area for photosynthesis is called the _____. | blade (Since seaweeds don't have a vascular system to transport nutrients, just about all parts of a seaweed conduct photosynthesis, not just the blade. For terrestrial plants with leaves, the flattened portion of a typical leaf is also called the blade.),  |
| The stemlike structure of a seaweed is called the _____. | stipe, |
| A(n) _____ is a unicellular photosynthetic alga with a unique, glassy, cell wall containing silica. | diatom, |
| _____ are short cellular appendages specialized for locomotion, formed from a core of nine outer doublet microtubules and two inner single microtubules ensheathed in an extension of the plasma membrane. | Cilia, |
| Under the old five kingdom system, the ____ kingdom included all eukaryotic organisms that couldn't be classified as plants, animals, or fungi. Under the new three domain system, advances in molecular biology have made scientists realize that _____ should actually be broken down into several kingdoms with some possibly being placed back into the plant, animal or fungal kingdoms. Therefore, _____ is an informal term used to describe mostly unicellular organisms that are not plants, animals, or fungi. | protist (the answer for all of the blanks) |
| A type of protozoan that moves by means of cilia is called a(n) _____. | ciliate (The paramecium in the picture below is a classic example of a ciliate. If you look closely, you can make out the small hairlike cilia.), |
| The protozoan pictured below is a(n) ______., | paramecium, |
| Protists that are animal-like in that they capture and consume food are called _______. | protozoans |
| The mutualistic collective formed by the symbiotic association between a fungus and a photosynthetic alga is called a(n) _____. | lichen (The picture below shows different species of lichens encrusted on a rock. Other types of lichens are found on the bark of trees. Instead of using a photosynthetic alga, some lichens use cyanobacteria for their photosynthetic part.), |
| A(n) ______ is a unicellular photosynthetic alga with two flagella situated in perpendicular grooves in cellulose plates covering the cell. | dinoflagellate (The alga that causes red tide is a dinoflagellate. Some dinoflagellates are bioluminscent which means that they can glow in the dark.), |
| A protist characterized by an anterior pocket, or chamber, from which one or two flagella emerge is called a(n) _____. | euglenid (The euglena pictured below is a classic example. Most euglenids are photosynthetic but can switch to a heterotrophic mode of food acquisition when light is unavailable.), |
| The protist pictured below is called a(n) _____., | euglena (a common freshwater alga), |
| Photosynthetic protists are commonly called _____ and can be either unicellular or multicellular. | algae |
| Algae and photosynthetic bacteria that drift passively in the pelagic zone of an aquatic environment are called ____. | phytoplankton |
| A type of protozoan characterized by great flexibility and the presence of pseudopodia is called a(n) _____. | Amoeba, |
| _______ are cellular extensions of amoeboid type cells used in moving and feeding. | Pseudopodia, |
| The term _____ refers to mostly microscopic organisms that drift passively or swim weakly near the surface of oceans, ponds, and lakes. | plankton (Some larger organisms such as multicellular floating seaweed, most jellyfish, and the Mola Mola fish are classified as plankton also. The fish is classified as plankton because it is not a strong enough swimmer to swim against ocean currents.) |
| The type of protists that are believed to have given rise to true plants are called _______. | green algae |
| * The ____ is the term that refers to the hardened shell of some protists, including forams and radiolarians, or the rigid endoskeleton of a sea urchin or sand dollar. | test, |
| The rootlike structure that anchors seaweed is called the ______. | holdfast, |
| The _______ shown below is an example of a colonial organism, meaning that it is a colony of individual cells that work together., | Volvox, |
| The protist pictured below is a(n) _____., | amoeba, |
