Transcript parasites fungi and variation traits

With Jordan R. and Daniela L.
Vocabulary/Key Terms:
 Eukaryotic: organisms that are composed of cells with
organelles on the inside.
 Heterotrophs: organisms that obtains its necessary
amounts of carbon from other organisms by consuming
them, whether dead or alive.
Parasites
 Feed off host
 Live in/on body
 Can cause infectious disease
 Specialized anatomically and physiologically
 Example: Tapeworms absorb nutrients through skin in
small intestine.
 Can also cause infectious disease
CHALLENGE: Name this parasite!

Sadly, they aren’t this cute:
Fungi
 Eukaryotic
 Heterotrophs
 Multi-cellular
 Reproduce both sexually and asexually (good when
environment is changing)
 Attack tissues of living plants and animals
 Competitors for food (attack food sources)
 Cause severe allergic reactions through mold spores
(budding)
CHALLENGE:
1- Guess who lived here

Vocabulary/Key Terms:
 Natural Selection:
Process in which species that have adapted will survive
and continue to reproduce (unlike species that couldn’t
adapt).
Vocabulary/Key Terms:
 Characteristic Change: when an organism’s physical
characteristics change over time
(Ex.) If one bird has a short beak and is unable to grab
food but then mates with a bird with a longer beak, their
offspring might have a longer beak.
Vocabulary/Key Terms:
 Phenotypes: an organism’s physical characteristics.
 Phenotypes influence many things, including:
 Find, obtain and use resources
 Ability to reproduce
Variation in Traits
 Variations exist within each organism’s phenotype in
every species.
 Natural selection plays a key part, especially when the
environment is changing.
 If a species has favorable characteristics, they will most
likely live.
 If a species doesn’t it will most likely end up dying out and
going extinct.
 Always certain diversity among a species.
 The more diversity, the better!

Test time!
Instructions:
 Each team will come up with a nickname, but base it off
of your material.
 Each team will receive a white board and will pick their
Recorder to write down their answers.
 There are 20 questions on this test, a bonus question
and 30 seconds to complete each question.
 Good luck!
Question #1
 Where do parasites mainly live?
 Answer: In or on their host
Question #2
 Define phenotypes and describe what they influence.
 Answer: they are an organism’s physical characteristics
and they affect an organism’s ability to reproduce and
find, obtain, and use resources
Question #3
 Are fungi eukaryotic or prokaryotic?
 Answer: Eukaryotic
Question #4
+
 How do tapeworms obtain their essential nutrients?
 Answer: By absorbing them through their skin.
Question #5
 How do fungi cause disease?
 Answer: They attack tissues of living plants and animals.
Question #6
 How does the diversity among a species affect the
repopulation of that species?
 Answer: if there is more diversity among the species,
there will be a greater chance that they repopulate and
continue to do so.
Question #7
 How do fungi repopulate asexually?
 Answer: They repopulate through budding.
Question #8
 Which picture best symbolizes a change in an organism’s
characteristics?
A:
B:
C:
D:
Question #9
 Complete the analogy:
 Climate:_____:: fungi: disease
 Answer: Characteristic change
Question #10
 How do heterotrophs get their necessary amount of
carbon?
 Answer: By consuming them, dead or alive.
BONUS QUESTION!!!
ARE YOU READY! (EXTRA CREDIT WORTH 5 POINTS)
Here it is…
 Compare and contrast how the variation in phenotypes
of parasites and fungi may benefit and harm them if the
environment were to change.
Congratulations!!!
Nice job! Keep up the good work!
