What organelle in the amoeba and paramecium is an adaptation to living in a hypotonic environment?
What shape are onion cells?
Bacteria have vacuoles.
A cell has the following molecules and structures: enzymes, DNA, ribosomes, plasma membrane, and mitochondria. It could be a cell from which of the following?
either a plant or an animal
A cellular diameter of 40 micrometers is equivalent to:
What is the function of vacuoles in plant cells?
Some amoeba can be pathogenic to humans.
What is the method of motility of paramecium?
Amoeba survive in what type of habitat?
The part of the onion you eat (and the part that was used for study in lab):
grows below ground.
Eukaryotic cells are typically larger than prokaryotic cells because:
their internal membrane system allows compartmentalization of functions and extra surface area for nutrient exchanged and placement of enzymes.
What is the stinging organelle of paramecium that assists it in capturing large prey?
Which of the following organelles enables the Euglena to be photoautotrophic?
What is the thick layer that surrounds each onion cell?
the plant circulatory system
How does the composition of bacterial cell walls differ from that of plant cell walls?
Bacteria have an extensive network of crosslinked teichoic acids in their cell walls, while plant cell walls are composed primarily of cellulose.
Bacteria have cell walls composed of peptidoglycan, while plant cell walls are composed primarily of cellulose.
Bacteria have cell walls composed of chitin, while plant cell walls are composed primarily of cellulose.
Both plants and bacteria have cell walls composed of cellulose; the cellulose fibers are more extensively crosslinked in bacteria than in plant cells.
- Question 20 2 out of 2 points
Bacteria have cell walls composed of peptidoglycan, while plant cell walls are composed primarily of cellulose
Paramecium are predators of:
What was the genus and species of amoeba you studied in lab?
What is the genus and species of the potentially deadly amoeba that causes amoebic meningoencephalitis?
In the absence of direct sunlight, the euglena might lose its:
Which organelle, within the paramecium, controls sexual reproduction?
Bacteria have cell walls.
What is the mechanism by which Euglena move?
extension of cytoskeletal structures
amoeboid movement and pseudopods
What part of the onion plant carries out photosynthesis?
all parts above ground
all parts above ground
How many flagella do Euglena have?
more than 2
Paramecium are heterotrophs. How do they obtain nutrients from their surroundings?
through the trichocyst
by releasing enzymes outside the cell to digest any available food sources in the immediate environment.
through their oral grooves.
by use of their contractractile vacuoles
through their oral grooves
By what mechanism do amoeba move?
:They secrete a mucopolysaccharide extracellularly that enable them to slide along moist surfaces.
They form pseudopods, and have cytoplasmic streaming.
They are ciliated organisms.
They are flagellated organisms.
They form pseudopods, and have cytoplasmic streaming
