What Periodic Table element do protists (ex: types of algae) produce? It is helpful to most living animals (including humans).

Which of the following is true of the flagellum in eukaryotes?     It is a long, thin extracellular (exterior) structure, with a basal motor embedded in the cell membrane/cell wall.     It is identical to the archaeal flagellum (archaellum) in composition and structure, but very different in composition and structure from bacterial flagella.     It is a long, thin structure containing bundles of microtubules and motor proteins, all within the plasma membrane.     Eukaryotic cells do not possess flagella.

This organism belongs to which Class? What is structure A? This organism is a member of which Order?

What is the difference between primary algae and secondary algae?  Six major groups of algae? How are these groups classified into these groups, and what is unique about each group?   What is the difference between diatoms and coccoliths found in algae.  What is the difference between foraminiferans and radiolarians found in protozoa?  What characteristics differentiate the protozoan groups (foraminiferans and radiolarians) from the algal groups (diatoms and coccoliths) microscopicly? Of what economic and academic value are algae?

which of the following best describes the gram positive (+) cell wall: O the peptidoglycan chain wraps around the cell only 1-2 times O a layer of polysacharrides and proteins ONLY has an outer membrane enclosing a thin layer of peptidoglycan O the peptidoglycan chain wraps around the cell many times O made of phospholipid bilayer only

Algae and protozoans are loosely grouped together as protozoans and are different from plants because they lack certain characteristics of plants. Explain what differentiates algae from plants and two ways they are different from protozoans. Talk about algae being part of our environment and how algae may positively or negatively impact our health or the environment.   (Words to use in your answer: cell wall, cell membrane, chloroplast, plankton, single-cell, multicellular, red tide, toxins, agar, phytoplankton, reproduction, motility, nutrition, feeding strategies)

While looking through your microscope under 100X total magnification you see a irregular shaped cell (a blob) with an obvious nucleus. You can also see the circulating cytoplasm in the cell cause a portion of the plasma membrane to bulge out in one direction allowing the cell to move to a new location on the slide. What kind protozoan would you say this was?

What is the arrangement of microtubules on the intracellular portion of a eukaryotic flagella? O Peritrichous O amphitrichous O 9+2 9+0

What is the brown pigment in brown algae called?
