Cell Division Flashcards
what is the characteristics of gram positive bacteria
Has no extra membrane absorb gram stain and turns it into purple
What is the function of a cell wall
Maintain shape, strength and stability of the plant
name three types of cytoskeleton
microfilaments, microtubules, intermediate filaments
what is function of microfilaments
Muscle contraction and provide support,
what is th functiom of microtubules
Main shape, provide support, seperate the chromes
what is the function of intermediate filaments.
To prevent excessive starch, maintain shape, fixes organelles
whats a nuclear envelope
doble membrane perforated with nucrear pores , impeamable to most substances.
Name two is a function of a nucleus
Sit efor synthesizing of ribosomes and mRNA, regulate metabolism
Whats a cistenae
Network of membranous tubules and flattened sacs
What is the function of RER
Synthesize protein, modify, package, and transport of secretory proteins
Substance get stud on the cisternae, gets in the lumen.
What is the function of SER
Name also two examples of processes involving it
It functions in diverse metabolic activities anchored by enzymes embedded on it
Testis and ovary produce sex hormone
gut epithelium synthesize lipid fro
What is the function of golgi body
receive,stores, modifies, packages and sorts proteins before distribution
What happens to the product of RER in the Golgi
They are modified from cis to trans pole by enzymes.
They are then marked and distributed to other parts of the body
What are ribosomes and its function
Small sperical granules, made of two (ribosomal)RNA strands
It synthesizes protien based on genetic info from mRNA using free amino acids.
What is the function of lysosomes
Has hydrolitoc enzymes to digest macromolecules
Autophagy=Old to new organelles
Autolysis=Digest ded organelles
