Question 6 Diatoms and Brown Algae are both But are grouped

Question 6

Diatoms and Brown Algae are both ______. But are grouped in a common clade because of the similarity of their ______ and this structure’s ____-like projections when present.

Photosynthetic – flagella – hair-

Brown or golden – photosynthetic structures – amoeba-

autotrophic – body forms --  pennate or centric-

Question 7

Amoebozoans include both _________ and __________. The second group was once classified as __________. But are now placed in this clade because among other characteristics they are __________ (mechanism of nutrition) like amoeba.

Red algae and Green algae – plants autotrophic

Zygomycota and Ascomycota – fungi -- heterotrophic

Slime Molds and Oomycetes – fungi -- heterotrophic

Amoebae and Slime Molds (mycetozoans) – fungi and animals – phagotrophic.

Question 8

The clade Euglenozoa includes organisms such as Trypanosoma and ________ a common type of structure for locomotion.

Euglena with a flagellum

Paramecium with cilia

Plankton in fresh water or oceans

The vertebrae hosts of these organisms

Question 9

Table 1 on p. 63 outlines four Supergroups, of which one is the Alveolates. Identify two groups within the Alveolates and their shared common characteristics.

2. Formaniniferas and Radiolarians with a test shell

1.Ciliates and Dinoflagellates with alveoli sacs below the cell membrane

4. Euglena with flagella for locomotion

3. Red and Brown algae with air sacks for flotation

Question 10

The idea of evolutionary convergence among other ideas is demonstrated in this lab (and others) by _________

Characteristics of organisms in one clade are shared with organisms in other groups or clades.

The fact that some protist lineages are ancestors of multicellular organisms such as plants and animals.

Characteristics common to all Protists.

Methods of locomotion and nutritional strategies are unique to protists.

Solution

Question 6
2. Photosynthetic-flagella-hair
Explanation: These are some of the distinguishable characteristics of thallophyta which include re, green and brown algae.

Question 7
4. Amoeba and slime molds (mycetozoans)-fungiand animals-phagotrophic

Question 8
1. Euglena with a flagella

Question 9
2. Ciliates and dinoflagellates with alveolar sac below the cell membrane

Question 10
2. The fact that protist lineages are ancestors of multicellular organisms such as plants and animals
Explanation: Protists vary in body form, nutrition and reproduction, and thus have been classifief into three main categories- animal like , plant like and fungus like.
