sequences
(all are correct)
Which of the following is a line of evidence supporting Endosymbiotic Theory?
false
Protists as a single taxonomic unit are considered a monophyletic group.
they're eukaryotic
What do all protists have in common?
Photosynthetic, Unicellular, and Multicellular
Algae are an ecological grouping of protists that are _____.

Protozoa is an ecological group of animal-like protists that are heterotrophic and feed
via "eating" smaller organisms.
supergroups
Which classification system uses phylogenetic relatedness to classify protists?
Excavata
You find a free-living protist that has a noticeable feeding grove that it uses to ingest
smaller organisms via phagocytosis. Which supergroup does it belong to?
Stramenopila, Alveolates, & Rhizarians
Which of the following make up the SAR Clade?
All have membrane vesicle sacs
Which of the following is a synapomorphy in Alveolates?
Alveolates
The protist that causes malaria and African sleeping sickness is found in which
taxonomic group?
All have spikey cytoplasmic extensions
Which of the following is a synapomorphy in Rhizarians?
They are photosynthetic
Which of the following is a synapomorphy in Archaeplastida?
, true
Land plants are included within the supergroup Archaeplastida.
They are within Unikonta and have a pseudopodia for movement
Which of the following is a synapomorphy in Amoebozoa?
They have a single flagella in swimming cells and are heterotrophic
Which of the following is a synapomorphy within Ophisthokonts?
true
Animals and Fungi are Ophisthokonts.
-Some are primary producers (photosynthetizers)
They help with marine carbon cycling
-They are primary consumers (heterotrophs)
-They sequester carbon
How do protists support biodiversity?
-They are major primary producers and key parts of aquatic food chains
-They are found in freshwater and marine habitats
-They have silicone-rich cell walls with a "box and lid" form

(all are correct)
Which of the following is true about Diatoms (clade: Stramenopila)?
Meristem tissue
Which of the following plant tissue types is a specialized region of undifferentiated cells
that experiences rapid cell division as the plant grows?
false
Meristem tissue is only found in the stem of a plant.
ground tissue
Which plant tissue comprises the majority of the plant and is used for a variety of
functions, including photosynthesis, storage, support, and resource transport?
Sclerenchyma
Dead cells. Hollow with a THICK cell wall. Provide strong structural support for the
plant. Also used in water transport.
Collenchyma
Living cells. Flexible support from irregularly thick cell walls. Supports growth of plant.
Parenchyma
Living cells. No cell walls. Used in storage and photosynthesis. Also used in nutrient
transport.
false
Dermal tissue is a THICK layer of cutin that protects leaves and minimizes evaporation
and water loss.
false
Xylem transports water in two directions: root to leaf and leaf to root.
true
Phloem transports water in two directions: root to leaf and leaf to root.
