1st STT - Gen bio : Module 4 Flashcards
What do you call the tiny structures that carry out a specific function within
the cell?
Organelles
What is the rigid layer of nonliving material that surrounds the cells of plants
which also protects the cell and provides structure?
Cell wall
Which cellular organelle acts like a post office for proteins?
Golgi apparatus
What organelle contains chemicals that break down certain materials in the
cell and aids in the removal of wastes from the cell?
Lysosomes
Which of the following statements is NOT true about the importance of
membranous organelles?
a. They increase the surface of membranes.
b. They recycle old, worn out cells within the cell.
c. Membranes are very good at organizing functionally related proteins.
d. Membrane-bound spaces permit the segregation of functions within the
cell and the concentration of specific functions.
They recycle old, worn out cells within the cell.
It is a flattened sac network that is continuous with the outer nuclear
membrane?
Endoplasmic reticulum
This is an acidic membrane-bound organelle that contain numerous hydrolytic
enzymes which catalyze hydrolysis reactions.
Lysosome
What do you call the organelles found only in plant cells that capture energy
from sunlight and use it to produce food for the cell
Chloroplasts
These are the toxins produced in cells have the potential to harm the cells that
is why it plays a crucial role of isolating it from the rest of the cell organelles
Central vacuole
Organelles, or separate compartments within a cell, are advantageous because
___.
They allow different chemical reactions within the cell to operate
simultaneously without interference from the cytoplasm or other reactions
happening in different organelles
It allows the exchange of molecules between two cells.
Vesicles
It is the site of photosynthesis.
Chloroplast
This is for water storage.
Vacuoles
This is the powerhouse of the cell.
Mitochondria
It is the protective envelope of a cell.
Cell Membrane
