Cell cleavage furrows
Posses a microtubular structure similar in form to a basal body
Centriole
which of the following is capable of converting light energy to chemical energy
Chloroplast
A biologist ground up some plant cells and then centrifuged the mixture. She obtained some organelles from the sediment in the test tube. The organelle took up CO2 and gave off O2. The organelle are most likely
Chloroplasts
Which of the following relationships between cell structure and their respective functions is NOT correct?
Chloroplasts; chief site of cellular respiration
Which of the following would be found in an animal call but NOT in a bacterial cell?
Endoplasmic reticulum
Plasmodesmata in plant cells are MOST similar in function to which of the following structure in animals cells?
Gap junction
Sorts out mixtures of substances and sends them to their proper destination
Golgi apparatus
In animal cells, hydrolytic enzyme are package to prevent general destruction of cellular components. which of the following organelles functions in this compartmentalization
Lysosome
Which of the following cell components is NOT directly involved in synthesis or secretion
Lysosome
Which of the following pairs is mismatched
Lysosome; protein synthesis
Digest damaged organelles
Lysosomes
All of the structure listed below are associated with movement in cells or by cells EXCEPT
Microbodies
Of the following, which cells structure would most likely be visible with a light microscope that had been manufactured to the maximum resolving power possible
Mitochondrion
Assembles ribosomal precursors
Nucleolus
Large numbers of ribosome are present in cells that specialize in producing which of the following molecules
Proteins
Found in both prokaryotic and eukaryotic cells
Ribosome
Makes steroid hormones
Smooth endoplasmic reticulum
Which type of organelle is primarily involved in the synthesis of lipids
Smooth endoplasmic reticulum
Cells can be describe a having a cytoskeleton of internal structures that contribute to the shape, organization, and movement of the cell. All of the following are part of the cytoskeleton EXCEPT
The cell wall
Eukaryotic cells are typically larger than prokaryotic cells because
Their internal membrane system allows compartmentalization of functions and extra surface area for nutrient exchange and placement of enzyme
Which of the following is NOT a known function of the cytoskeleton
To maintain a critical limit on cell size
A primary objective of cell fractionation is
To separate the major organelles so their particular functions can be determined
Cilia and flagella move
When the bending of microtubules is powered by ATP
