Q

advantages of biodiversity

A

supports food security
sustains livelihood through overall genetic diversity
a large number of plants=variety of crops
greater species diversity ensures natural sustainability
healthy ecosystems can withstand disasters
humans have negative effect on biodiversity

features of organisms

A

nutrition= autotrophic(makes own food), heterotrophic(feeds on living)

cell organisation=unicellular, multicellular

16
Q

how many species are there?

A

9-10 million
most known are insects(1 million)

17
Q

plant kingdom

A

species of vegetation
one of the oldest
immobile, autotrophic, multicell, eukaryotic
sexual or asexual
vascular and non vascular

18
Q

fungi

A

unicellular + multicellular
RECYCLING
chitin in their walls, feed of other living things,
reproduce through spores
some have toxins
beneficial ones= penicilin+antibiotics

19
Q

protista

A

primitive of eukaryotes
eukaryotic organisms that are not deemed to be animals, plants, fungi such as protozoa
ex: euglena, amoeba, paramecium, algea
some have organelles that are found in animal cells(mitochondria), while others have organelles that are found in plant cells(chloroplast)

20
Q

monera kingdom(archra+eubacteria)

A

microscopic+prokaryotes
present in all habitats and is made up of single-cell things with no defined nucleus
most bacteria are aerobic and hetetrophic
archea usually anaerobic and metabolism is chemosynthetic
some bacteria are photosynthetic

21
Q

archabacteria

A

cell wall composition= for extreme conditions

archea of methonogon=found in guts of humans and animals

reproduce by binary fission(asexual)

1 circular chromosome

use flagella to move

22
Q

eubacteria

A

considered true bacteria
in every environment
compose human microbiota
ensures our body to function normally

23
Q

human microbiota

A

healthy growth
protect body
help digestion
regulate moods

24
Q

distruption of microbiata

A

know as dysbiosis

results in obesity, dermotits, neurological imbalance, irritable bowel syndrome

cure= probiotics, prebiotcs

25
Q

how do gut bacterias affect our body?

A

gut-brain= autism, psychiotric disorders, pneumonia, neurodegenerarive disorders

heart diesease= hearth failure, atheroscleros thrombiosis

gut-skin= psoriosis, acne vulgaris, skin cancer

metabolsim=obesity, T2 diabetes, cancer, mitochondrial dysfunction

gut-lung=asthma, lung cancer, obstructive pulmonary disease

26
Q

microorganisms on surface…

A

guard against invasion
healing wounds
immune syustems
produce signaling molecules

27
Q

gut…

A

harbores the highest amount of microorganisms

microbes in gut posses enzymes to digest carbohydrates and extraction of nutrients

28
Q

intestinal microorgnaisms…

A

produce K2 B12
active role in medication we ingest
first to interact with drugs

29
Q

babies???

A

get microorgansisms from their moms during delivery
lactobacilli= in moms vagina= cesarean= colonize baby’s intestines to help in digestion of milk

after birth microorganism are obtained from diet= breast milk= acquire bacteria from mother’s skin that colonize baby’s intestines

30
Q

ecosystems 2 components

A

abiotic(non-living)
biotic(living)

31
Q

it takes up … years to get enough microbes

A

2

32
Q

tardigrades

A

micro animal
live in water moss algae
for over 500 million years
survived artic, space,
turn into tun= release water this is called cryptobiosis
organs protected by sugary gel called trehalose
can survive 1000x more radiation than us

33
Q

can plants communicate using the electricity

A

yes

34
Q

kingdoms are

A

Archaebacteria (ancient bacteria)
Eubacteria (true bacteria)
Protista
Fungi
Plantae
Animalia
