Organelles Flashcards
What is the function of the mitochondria?
The mitochondria are known as the powerhouse of the cell, responsible for producing ATP through cellular respiration.
What is the primary role of ribosomes in a cell?
Ribosomes are responsible for synthesizing proteins by translating messenger RNA.
Multiple Choice: Which organelle is known for its role in photosynthesis? A) Mitochondria B) Chloroplast C) Nucleus D) Ribosome
B) Chloroplast
What structure surrounds and protects the cell, regulating what enters and exits?
Cell membrane
True or False: The nucleus contains the cell’s genetic material.
True
What is the function of the cytoskeleton?
The cytoskeleton provides structural support and facilitates cell movement and transport within the cell.
where can organelles be situated
in the cytoplasm and on the surface of the cell
do all organelles have membranes
no
what is the cytoskeleton
protein filaments that run through cell
function cytoskeleton
- transport stuff
-movement of cell
-cell division
-shape
what is in the nucleus
-nuclear envelope
-nucleolus
-chromatin
what is nuclear envelope
sélective isolate the content of the nucleus from cytoplasm
what is nuleolus
location where the ribosomes are built
what is chromatin
storage of dna. contains info needed to operate cell
What is the rough endoplasmic reticulum (RER)?
The rough endoplasmic reticulum is a type of endoplasmic reticulum that is studded with ribosomes on its cytoplasmic surface, giving it a ‘rough’ appearance.
True or False: The rough endoplasmic reticulum is involved in the synthesis of proteins.
True
Fill in the blank: The rough endoplasmic reticulum is primarily responsible for the synthesis of __________ proteins.
secretory and membrane-bound
What role do ribosomes play in the function of the rough endoplasmic reticulum?
Ribosomes on the rough endoplasmic reticulum translate mRNA into polypeptide chains, which are then processed and folded within the RER.
what does the mitochondia do for the cell
uses oxygen th produce the big part of the cell energy
what is this called :uses oxygen th produce the big part of the cell energy
aerobic cellular respiration
