ICA EXAM #2
Which of the following structures are important for providing energy for cytoplasmic
functions in a plant? - ✔️✔️mitochondrion
Both mitochondria and chloroplast are maternally inherited. Some plants develop
resistance to atrazine herbicide through a mutation of a gene located in chloroplast. If
male plants without any such herbicide resistance are crossed with an atrazine resistant
female plant, what will be the resistance level of offspring plants? - ✔️✔️All offspring
will be resistant.
Damage in mitochondrial DNA will have the most effect on - ✔️✔️respiration and ATP
synthesis
How do you think the double membrane structure of mitochondrion is able to help in its
function to make ATP? - ✔️✔️Maintaining conditions within and between the two
membranes to allow ATP synthesis
Which of the following action, a plant cell will not be able to do? - ✔️✔️Cleavage furrow
formation during cell division
Which of the following cytoskeleton elements or associated proteins/structures are not
involved in the cellular movement or molecular transport? - ✔️✔️Intermediate filaments
All of the following are part of or cell junctions of animal cells except -
✔️✔️plasmodesmata.
If you were to genetically engineer a papaya plant that will resist a fungal rot disease,
you would like to express high levels of the enzyme _____________ that will degrade
the fungal cell wall. - ✔️✔️chitinase.
Which of the following is the correct sequence of plant cell structural layers, beginning
with the cytoplasmic side and progressing outward? - ✔️✔️Plasma membrane,
secondary wall, primary wall, middle lamella
The digestive tract lining contains epithelial (outer lining) cells that do not allow food
particles to randomly go inside the body except through specific proteins on their cell
membrane. Which of the following structure blocks random diffusion of food particles
between epithelial cells? - ✔️✔️) Tight junctions
