The chloroplast found within a photosynthetic protist is c) Two are from the originally engulfed photosynthetic bacterium; one is a protist
surrounded by four membranes. How can we account for membrane; the other is from the food vacuole produced by the protist originally
this? containing the bacterium
a) One is from the bacterium, one is from the protest, one
is from the bacterial nuclear membrane, and one is from a
food vacuole
b) Four membranes evolved from the protist's cell
membrane
c) Two are from the originally engulfed photosynthetic
bacterium; one is a protist membrane; the other is from
the food vacuole produced by the protist originally
containing the bacterium
d) All four are bacterial membranes
e) All four are protist membranes.

b) reproduction is asexual in protists
c) protist reproduction never includes the formation and
development of an embryo
d) the life cycles of protists are very similar; those of
plants and animals vary greatly
What is one negative impact protists have on humans? c) Many human diseases are caused by protists
a) Photosynthetic protists in Earth's oceans produce
oxygen that replenishes the atmosphere.
b) Protists are slowly replacing bacteria in our ecosystem
c) Many human diseases are caused by protists

1) Photosynthetic protists are collectively known as 1) algae
___________ 2) protozoa
2) Nonphotosynthetic protists are collectively known as
__________
are single-celled photosynthetic protists that live in the phytoplankton
upper layers of Earth's lakes and oceans.
are alveolates with a round shape and two whip-like dinoflagellates
flagella that propel them through the water.
The flexible cell membranes of some single-celled pseudopods
protists can form extensions called_________ that reach
out and engulf prey.
are euglenozoans with distinctly structured mitochondria. kinetoplastids
are excavates that live inside animals in a mutualistic parabasalids
relationship with their host.
hollow and very absorbent (have several different silica
shapes, especially circles and differentiating triangles---
like a fidget spinner)
