Protists 1 Protists 2 Botany 1 Botany 2 Amphibians
a)Most protists are comprised of this #
of___cells(s)?
b)This type of protist is
multicellular.
a-One
b-Kelp
What are the three major types of
protists?
Plant-like
Animal-like
Fungi-like
What is the term that describes
asexual reproduction in
single-celled protists?
Binary Fission
The pigment___is present in all algae; it appears____in color because that is the wavelength of light
that it does not reflect.
-Chlorophyll-Green
What is the term for animal-like protists that are motile (can
move)?
Protozoans Note: this term is used
inconsistently; some biologist do…some don’t.
Why? Well, it’s complicated…look it up if you’re really
interested.
Protists have a nucleus. That means they belong
to which domain?
Eukaryota
Humans and protists both function at the organism
level. Which organizational
levels do humans have that protists lack?
-Tissue-Organ
-Organ System
This organism is responsible for most of the oxygen generated on
Earth.
Phytoplankton!
What does an amoeba (ameba) use its
pseudopodia for?
Locomotion and feeding
How do planarians reproduce asexually?Yeah…I know they’re
not protists.
Regeneration
What characteristics are shared by most plants?
-Cells have cell walls-Autotrophs-Chlorophyll
-Waxy Cuticle
What do plants produce during their sporophyte generation?
Spores…DUH!
What do plants and algae have in common?
-Chlorophyll-Cells have cell walls-Mostly autotrophic-two-stage life cycle
What is phototropism?
Tropisms are movement in response to a stimulus. Phototropism is a
specific type that refers to movement of plants toward a light source.
Gravity is another source of tropism…geotropism.
Two Part Question:1.Which group of plants makes up
the bulk of our agricultural produce?
2. Do gymnosperms and angiosperms both produce seeds?
1.Angiosperms
2. Yup…they shur do
What are two differences between monocots and dicots?
Monocots: -one cotyledon
-vascular tissue randomly arrangedDicots:
-Two cotyledons-Vascular tissues arranged circumferentially (in a circle)
What is the function of a plant’s roots?
-Provide water and minerals-Support
-Store nutrients
What are two types of vascular tissue in plants and what is the
function of each?
How do the cells of nonvascular plants get water and nutrients?
1.Xylem: Water TransportPhloem: Nutrient
Transport
2.Diffusion and osmosis from the environment or
from nearby cells
What are the three parts of a seed?
-Seed Coat-Cotyledon (seed
leaf)-Embryo (young
plant)
Two Part Question:1. What is the male part of the flower
called?2.What is the
female part of the flower called?
1. The Stamen2. The Pistil
Name three types of amphibians.
-Caecilians-Frogs & Toads-Salamanders
What are the stages of frog metamorphosis?
1. Fertilized egg2. Tadpole
3. Metamorph4. Adult Frog
Amphibians are very sensitive to changes in water quality and
climate. What is the term used for these type of organisms?
Environmental
Indicators
How does gas exchange take place in amphibians?
Via skin and lungs.
How do amphibians reproduce?
Sexual Reproduction via External
Fertilization.
