UNIT 5 INTO THE CELLS
Plant cells can communicate with each other using what structure?
plasmodesmata
Chromosomes are made from
condensed chromatin
Eukaryotic cells move their organelles using
the cytoskeleton
What is considered correct when comparing plant and animal cells?
Both plant and animal cells have a plasma membrane, and plant cells also have a cell wall
What organelle would form a membrane-bound package, also known as a vesicle?
Golgi apparatus
Plant cells have plasmodesmata that
connect the cytoplasm of one cell with that of another
What describes the function of a chloroplast?
It converts light energy into chemical energy
A cell being observed under a microscope has a cell wall, plasma membrane, ribosomes, and chromosomal material that is not found in a nucleus. Based on this information, the cell could be a
bacterial cell
Mitochondria are found in
both plant cells and animal cells
Chloroplasts and mitochondria are similar in that they both
contain DNA
All cells have some characteristics in common; both prokaryotic and eukaryotic cells have
cytoplasm, a plasma membrane, and DNA
A stack of thylakoids inside a chloroplast are known as what?
granum
What does the folding of the mitochondrial inner membrane provide?
greater surface area for ATP production
Compared with a eukaryotic cell, a prokaryotic cell
lacks organelles beyond ribosomes
Carrie would like to observe the cilia on the surface of a live paramecium—a single-celled organism. The best device to do this would be a
light microscope
Bacteria hold their DNA in a region inside of their outer membrane. What is this region called?
nucleoid
What feature is found in all cells?
plasma membrane composed of phospholipids
What organelle is not surrounded by a membrane?
ribosomes
What is considered an incorrect match?
smooth endoplasmic reticulum - storage of water
Cell size is limited because ________ is critical to a cell's function.
surface-area-to-volume ratio
