What is the main function associated with smooth endoplasmic reticulum?
Phospholipid production
Which type of endoplasmic reticulum has ribosomes on its surface?
Rough endoplasmic reticulum
What is the shape of the smooth endoplasmic reticulum?
Tubular form
Aside from protein synthesis, what is another important function of the rough endoplasmic reticulum?
Protein folding
Which organelle is responsible for transporting the products of rough endoplasmic reticulum to other cellular organelles like Golgi apparatus?
Smooth endoplasmic reticulum
What is the primary function of the smooth endoplasmic reticulum?
Synthesizing essential lipids and steroid hormones
How do prokaryotic cells differ from eukaryotic cells in terms of DNA organization?
Prokaryotes have DNA enclosed in a nucleus, while eukaryotes have DNA in a central region called nucleoid
Which statement accurately describes prokaryotic cells?
They lack a true nucleus and membrane-bound organelles
What do mitochondria and chloroplasts have in common based on the endosymbiont theory?
They were once free-living cells
Which organelle was NOT mentioned as an example of an endosymbiont in the text?
Nucleus
Why are smooth endoplasmic reticulum (SER) and rough endoplasmic reticulum (RER) important for cell function?
SER synthesizes lipids, while RER synthesizes proteins
What is the main idea behind the Endosymbiotic Theory?
Mitochondria and chloroplasts were once aerobic bacteria ingested by a prokaryotic cell.
What is the role of organelles in cells?
To carry out life functions within the cell.
How do cells become specialized for specific roles?
Through a process called specialization.
Which of the following is NOT one of the main types of tissues found in the human body?
Skeletal tissue
What defines a group of tissues working together in the body?
An organ
From which prokaryotic organisms did mitochondria and chloroplasts in eukaryotic cells evolve?
Aerobic bacteria
Learn about the Endosymbiotic Theory which explains the origins of mitochondria and chloroplasts in eukaryotic cells as once independent prokaryotic organisms. Explore how eukaryotic cells may have evolved from prokaryotic cells through symbiosis.
