3.1- 3.5 - Cell Organelles Flashcards
What do all eukaryotes cells have?
Nucleus and membrane-bound organelles
What are multiple cells called?
tissues
What are multiple organs called?
Organ system
What are multiple tissues called?
Organs
What is the struture of the nucleus?
Surrounded by a double membrane, with pores that allow molecules to enter and leave
What is the function of the nucleus?
Stores DNA and coordinates cells activities
What is the structure of the nucleolus?
found within the nucleus made of proteins and RNA
What is the function of nucleolus?
Produces ribosomes
What is the function of rough endoplasmic reticulum?
protein synthesis and folding
What is the structure of rough endoplasmic reticulum?
a series of flattened sacs with lots of ribosomes
What is the structure of smooth endoplasmic reticulum?
a series of membrane-bound sacs, without ribosomes on the surface
What is the function of smooth endoplasmic reticulum?
produces and processes lipids
What is the structure of the golgi apparatus?
Flat, curved, fluid-filled sacs surrounded by vescicles
What is the function of the golgi apparatus?
processes and packages proteins and lipids which produces lysosomes
What is the fucntion of mitochondria?
site of respiration and therefore ATP production
What is the structure of centrioles?
hollow cylinders containing microtubules
What is the function of centrioles?
Involved in cell division
What is the function of ribosomes?
site of protein synthesis
What is the structurre of lysosomes?
vesicles filled with digestive enzymes, bound by a memebrane
What is the function of the lysosomes?
breakdown any of the cell’s waste, destroy disease-causing organisms that enter the cell
What is the role of the rER in transporting proteins?
Proteins produced on the riboosomes of rER are folded and processed then transported in vesicles to golgi
What is the role of the golgi apparatus in transporting proteins?
Modified and repackaged to be transported around the cell or leave by exocytosis
What is the fucntion of the cell wall?
Provides strength and support
What is the function of the capsule?
Prevents cell from drying out, helps adhesion to surfaces
