Fill in the blank.

  1. Different protists use cilia, _______, or pseudopodia to move.
  2. Green algae are closely related to plants, and _______ is what gives them their green color.
  3. Protists in the genus plasmodium must live in host cells and harm their host cells, providing an example of a _______ relationship.

Respond to the following based on your reading.

  1. Why have scientists recently rejected classifying protists in their own kingdom?
  2. What are the three main ways that protists can move?
  3. The eukaryote that causes red tide is known as what?
  4. The organisms that push carbon to the bottom of the ocean are known as what? Why is this important to the ecosystem?
  5. How is the endosymbiotic theory used to support the emergence of Eukaryota?
 

1 Flagella
2 chlorophyll
3 parasitic
4 its a diverse group and some scientists put protists in their own kingdom but when they try to explain protists as a kingdom there is always an exception to at least one rule on a chain of rules
5Using flagella
Using cilia
Using pseudopods or axopodia
6Karenia brevis
7 phytoplankton. They are primary producers of the ocean
8 It describes the mechanism of how eukaryotic cells developed from prokaryotic cells. It involved mutual cooperative or endosymbiotic relationship
   
  1. flagella
  2. chlorophyll
  3. parasitic
  4. Scientists have recently rejected "Protista" as a kingdom because as evolutionary and molecular knowledge continues to increase, the relationships among organisms are strengthened that weren't previously considered. It continues to be found that many protists don't share common ancestry with other protists that don't exclude other groups, such as plants, animals, and fungi. Protists had been previously classified through what they are not: plants, fungi, or animals. They share no characteristics that aren't also shared by "nonprotists."
  5. The three main ways protists can move are through cilia, flagella, and pseudopods. All of these structures help protists to move in different ways through their environment.
  6. The eukaryote that causes red tide is known as a dinoflagellate.
  7. The eukaryotes that push carbon to the bottom of the ocean are known as diatoms. This is important to the ecosystem because it lowers the overall carbon dioxide levels in the air and buries the carbon deep in the sea.
  8. The endosymbiotic theory posits that eukaryotes emerged when one or more prokaryotic cells ingested another prokaryotic cell, leading to the eventual eukaryotic cell.

Fill in the blank.

  1. Multicellular fungi have a _______ stage and a reproductive stage of their lives.
  2. Many fungi play a critical environmental role as _______, breaking down organic material into nutrients for the soil and other organisms.
  3. Some fungi and insects benefit each other; the fungi protects the insects from predators and the insects spread spores for the fungi. This is an example of a _______ relationship.

Respond to the following based on your reading.

  1. What's the primary way that fungi spread and reproduce on Earth?
  2. What's the role of mycorrhizae in plants? What kind of relationship is this?
  3. What are the three main substances that fungi are able to turn into usable forms for other organisms?
  4. What's one way that fungi help to maintain homeostasis in ecosystems?
  5. Why is it helpful that fungi attack and kill other parasitic organisms?
 

1 vegetative
2  decomposers
3 mutualistic
4 by spores
5 plants that grow in roots--mutually beneficial relationship
6Phosphorus, nitrogen, and carbon
7 By breaking down organic matter and converting it into nutrients
8 because they establish parasitic relationships, they serve as mediators, linking different organisms and ecosystems
   
  1. vegetative
  2. decomposers
  3. mutualistic
  4. The primary way that fungi reproduce and spread their species on Earth is through spores. These spores are carried by the wind or by other organisms.
  5. The role of mycorrhizae in plants is that they live in the roots of plants and turn unusable matter into minerals and water for the plants. The plants also provide energy and a place for the mycorrhiza to live.
  6. The three main substances that fungi convert into usable forms for other organisms are phosphorus, nitrogen, and carbon.
  7. Fungi break down organic matter and convert it into usable nutrients.
  8. It's helpful that fungi attack and kill other organisms that are parasitic because these parasitic organisms can wreak havoc on the ecosystem. The fungi help to protect other species and populations by controlling and curbing the growth of the parasitic organism.
