Protoctista & Fungi

Question 1

Define Protzoa

Answer 1

single celled eukaryotes that commonly show characterstics usually associated with animals, most notably, mobility and heterotrophy

Question 2

What are the 4 types of Protozoans based on locomotion (type of movement)

Answer 2

1. Amoeba: crawl along surface by extending pseudopodia(fake feet, used for movement and feeding). Reproduce via Binary Fission
2. Flagellates: use flasgellates to move. ex, TRY-PAN-SOMES, which causes:
   - African Sleeping: transmittted by the TseTse Fly
   - American Sleeping: transmitted by Bed Bugs
3. The Ciliate: move using Cilia ex, PARA-MECLUM which has two nuclei and a gap to maintain internal balance ‘
4. The Apicomplexa: ex, PLASMODIUM which causes malaria and is transmitted through female Anopheles mosquitos

Question 3

Types of SACRODIA

Answer 3

1. Fora-mini-ferans (used by geoligists to determine the age of rocks and* identify possible sites of drilling*)
2. Radio-larians

Question 4

What are PLANT-LIKE PROTISTS?

Answer 4

Algae: Autrophic protists that carry out a proccesss of photosynthesis

Question 5

What are the 4 divisions of Plant-Like Protists?

Answer 5

1. Diatoms: cell wall made of Silica
2. Eu-glenoids or Euglena: have a light-sensitive reseptro9eye-spot) and a contractive vacuole that maintaisn homeostatis
3. Green Algae: liek SPIRO-GRYA AND volvoz
4. Red Algae: used infood

Question 6

What are FUNGUE-LIKE PROTISTS?

Answer 6

Protists that get their food by absorbing nutrients from dead, decaying creatures, it’s cell wall is composed of cellulose, like slime molds

Question 7

List the charactersitcs of FUNGI

Answer 7

1. Hetrotroph
2. Eukaryotes
3. Living prganism
4. Decomposer
5. Digests its food before ingegestion with the use of enzymes
   6 . Cell wall made of Chitin

Question 8

What are the two types of Fungi?

Answer 8

1. UNICELLULAR: Yeast
2. Multicellular:
   All other types of Mushrooms

Question 9

What are the types of reproduction in Fungi

Answer 9

1. Sexual reproduction
2. Asexual reproduction: by
   - Budding
   - Fragmentation
   - Spore productions

Question 10

What is an example of a fungus-like protists

Answer 10

Slime molds

Question 11

What are the two classes for Protists?

Answer 11

Plant-like and Animal-like

Question 12

Describe the structure of the FUNGI

Answer 12

It’s main structure are called MY-CELIUM which is made up of a strands of HYPHAE where fungi absorb nutrients

They also have a Fruting Body which is used to reproduction

Question 13

What are the three types of FUNGI according to their feeding style?

Answer 13

1. **Sapro-phytic **: feed or dead or decaying organisims
2. **Parasitic **: feed on a host body they invade
3. Mutualistic: they feed on their host body but also norish it

Question 14

What are FOUR phylums of FUNGI

Answer 14

1. Chy-tri-di-mycota (chytrids):
   - unicellular
   - aquatic
   - produces flagellated spores
2. Zy-go-mycota (common mold)
   - reproduces sexually zygo-spores
   - ex, bread mold
3. Asco-mycota (sac family):
   - reproduces sexually by producing asco-spores
   - ex, yeast - aspergillus
4. Basido-mycota (club fungi):
   - reproduce sexually by producing basidio-spores
   - ex, mushrom

Question 15

Uses of FUNGI in Medicine

Answer 15

Penicillium is used to make the Antibiotic PENICILLIN

Question 16

Uses of FUNGI in FOOD

Answer 16

TRUFFLE, MUSHROMS, AND YEAST are used in the making of BREAD AND CHEESE
