Two of the above

A

Chlorophyta

19
Q

Which of the following are marine algae?

Phaeophyta
Chrysophyta

Two of the above

A

Two of the above (Phaeophyta & Rhodophyta)

20
Q

Describe Division Cyanobacteria:

A
  • Cyano mean - “blue/purple”
  • OG classed as Kingdom Protista (SK Algae) BUT ARE NOT = are Prok. = Kingdom Monera
    -> FORMERLY known as Blue-Green Algae
  • Simplest photosynthetic organism
  • Major producers of oxygen
21
Q

What are the major procedures of oxygen?

Amoeba
Pseudopodia
Cyanobacteria
Euglenophyta

A

Cyanobacteria

22
Q

Describe Kingdom Fungi

A
  • Domain Eukarya = eukaryotic

Two major groups:

  • Yeast (shiny and tiny)
    -> Unicellular
    -> Found in warmer environments (ex: body temp)
  • Mold (large, fuzzy, multicolored colonies)
    -> Multicellular
    -> Found in colder enviromnemts (ex: room temp)
23
Q

Which of the following is wrong about yeast?

  • It is multicellular
  • It can be found in colder environments
  • It can be found in warmer environments
  • Two of the above*
A

Two of the above (It is multicellular & it can be found in colder environments)

24
Q

Describe Mold (its major functions)

A
  • Decomposes organic waste (ex: dead tree) by secreting extracellular enzymes (to digest waste)
  • Absorb nutrients from decomposed matter through hyphae (extensive network on long, filamentous cells)
    -> mode of aquiring nutrients UNIQUE TO FUNGI
  • Fungi are “saprophytic heterotrophs” or “saprobes”, which are organisms that lives off of dead or decaying organic material (rely on other organism for food)
25
True or False: Fungi are known as photoautotrophs.
False, fungi are “saprophytic heterotrophs” or "saprobes" meaning they rely on other organisms for food; lives off dead or decaying organic material.
26
Define: Hyphae
network of long, branching filamentous structures; used to absorb nutrients from decomposed matter
27
Define: Mycelium
collection/mass of hyphae
28
Define: Sporangium
spore-bearing structures (found at end of hyphae)
29
Define: Spores
released from sporangia through air
30
Describe Mold Spores (production, location, reproduction)
- Mold can produce large numbers of various types of spores - Spores contained in a specialized spore-bearing structures called sporangia/sporangium - Spores are disseminated in nature through the air in large numbers for the purpose of reproduction - Spores become the new hyphae → new mold
31
Describe the description and function of the hyphae
- FXN: absorb nutrients from the environment - Consist of nuclei, cytoplasm and organelles (some have cell wall (septum) between cells) - Two types based on presence/absence of cell wall --> One long cell with multiple nucelli → non-septated hyphae --> Multiple cells with a single nucleus per cell → septated hyphae
32
Which type of hyphae is composed of individual cells, have a septum and have a nucleus per cell?
Septated Hyphae
33
Which type of hyphae is composes of multiple nuclei and have no septum?
Non-septated Hyphae
34
Describe the uses of yeast and how they reproduce.
- Commercial use: in the alcohol and bread-making industries - Most fungi reproduce by budding (asexual reproduction) --> Small portion of parent cell “pinches off” or buds off to become a daughter cell
35
True or False: yeast is an asexual reproduction that consist of even division to make a parent and daughter cell
False, yeast is an asexual reproduction that consists of *uneven* division to create a parent and daughter cell. Binary fission (in bacteria) is about *even* division of parent cell into daughter cells.
36
What is the process that bacteria uses to reproduce?
Bacteria uses a asexual reproduction known as binary fission which is an even division of the bacteria to create two bacteria.
37
Know how to label hyphae, septum, sporangium, spores, and mycelium.
Check slide 6 on week 3 lab
38
Be able to label Amoeba: Pseudopodia, Nucleus, Cell membrane
check slide 7 in week 2 lab
