Question

Give an organism representing each of the following groups or conditions: 1) Excavates 2) Rhizarians 3) Nonphotosyntheticstramenopiles 4) Ciliated protist 5) Flagellated protist 6) Amoeboid protist 7) Protist whose plastid likely arose by secondary endosymbiosis 8) Protist with no functional mitochondria 9) A protist that forms a calcium carbonate shell

Answer 1

1. Euglena.

2. Radiolarian.

3. Oomycetes.

4. Paramecium.

,5. Euglena.

6. Amoeba.

7. Green algae.

8. Parabasalids.

9. Coraline algae.

Step-by-step explanation:

Excavates are group of unicellular animal that are eukaryotes. These group of animals are flagellates i.e they have flagella for locomotion. They lack classical Mitochondria.

E.g Euglena.

Rhizarians are group of unicellular eukaryotes organisms,most are non photosynthetic. Many of them produce shells or skeleton. They are amoebiod like with pseudopods. E.g Radiolarian.

Non photosyntheticstramenopiles are group of heterotroph stramenopiles or heterokonts that are unicellular eukaryotes. They have hairy flagella and don't produce their food. E.g oomycetes.

Ciliated protists are free living organisms that move by using cilia, a structure that propel to aid movement. E.g paramecium.

Flagellates protists are organisms that have flagella which is use for propulsion and moving food into the body . E.g Euglena.

Amoebiod protists are group of unicellular organisms that live in fresh and marine water. The have pseudopods for movement and feeding. The engulf with the aid of pseudopods. E.g Amoeba.

Protists that their plasids arose from secondary endosymbiosis i.e eukaryotes engulf another eukaryotes. E.g green Algae.

Protists with no functional mitochondrial include parabasalids but they have hydrogenosome.

Protists that form calcium carbonate cells include Coraline algae.

Answer 2

Organism and their group or conditions

Step-by-step explanation:

1. Excavates:Excavates are the super groups of protists having an appearance which is asymmetrical and also having a feeding groove which is excavated from one side,organism representing this group is Euglena
2. Rhizarians:It is also a subgroup of protists, amoeboid in nature characterised by having pseudopodia (thin and needle like) which helps in engulfing food,organisms representing this group are Paulinella
3. Non photosynthetic stramenophiles-These are also a group of protists which are non photosynthetic in nature,have fine hair like projections on their flagella,organisms representing this group are water molds
4. Ciliated protist-These are a group of protists which are characterized by the presence of cilia(hair like organelles),found in rivers,lakes,oceans and soils;example of this group is Paramecia
5. Flagellated protist-These protists have a tail like projection called flagellum which hepls in circular motion,found mainly in moist environments;example of this group includes Trypanosoma
6. Amoeboid protist-These are a large of unicellular organisms having false structure called pseudopodia(helps in movement and feeding);an organism representing such group is Paramecium
7. Protist whose plastid likely arose by secondary endosymbiosis-Secondary endosymbiosis occurs when a living cell engulfs another eukaryote cell which has already undergone primary endosymbiosis(endosymbiosis means one symbiotic organism lives inside another);oragnisms which underwent such condition is diatoms
8. Protist with no functional mitochondria- Parabasalids are anaerobes protists which lack functional mitochondria
9. A protist that forms a calcium carbonate-Forams are protist which live in oceans and forms calcium carbonate in the form of a shell
