Nucleus
What are the 3 Main parts of the nucleus?
Nuclear envelope, the chromatin and nucleolus
Is a maze of channels that begins at the nuclear envelope and winds through the cytosol (makes lipids and proteins)
Endoplasmic reticulum
Which are the 3 organels without membranes
Ribosomes, cytoskeleton, centrioles
Consist mainly of cellulose fibres arranged in a overlapping fasion to allow carbon dioxide, oxigen and water to flow through it
The cell wall
Does the animal cells contain endoplasmic reticulum?
yes/no
yes
It is a membrane formed by two lipid bilayers whose structure is performed by nuclear pores with proteins attached inside.
Nuclear envelope
Mention the two types of endoplasmic reticulums
Rough endoplasmic reticulum and smooth endoplasmic reticulum
They are responsable for protein synthesis and can be founded attaches to the endoplasmic reticulum
Ribosomes
it is a mixture of supporting proteins and polysaccharides that binds adjacent cells together
Extracellilar matrix
They transport, store, or disintegrate substances in the cell
Vesicles
Allow the passage of small ions and dissolved molecules
Nuclear envelope PROTEINS
Endoplasmic reticulum that it’s mambranes are covered by ribosomes and its function is to synthesize proteins
Rough endoplasmic reticulum
Organnel that support the and shape the cell
Cytoskeleton
Its funcion is to separate the cell´s interior from its environment and act as a selective barrier that allows oxygen, nutrients and waste to pass through
The membrane
They degrade unwanted substances
Lybosomes
They are molecules that can be seen as long strands folded and twisted into compact structures
DNA molecules
Organelle that waste, debris or toxic residues are isolated and disposed of. (They can also store nutrients or ions)
Vacuoles
True or false:
Does the microfilaments (one of the 3 primary fibers) are the thickest and are composed of tubulin
False (microtubules)
Say the two parts of phospholipids
Hydrophilic head
hydrophylic tail
They are the central producer of enegy through aerobic metabolisim
Mitochondria
It is the site of ribosome manufacture and it is composed of ribosomal RNA, chromosome secretion, proteins and ribosomes in various shnthesis stages
Nucleolus
Organelles made of membranes where the outer membrane is smooth and the inner membrane forms series of folds called cristae
Mitochondria
Structures formed by a set of microtubkes arranged in a cylinder
Controiles
Model that considers the cell membrane a double layer of compacted phospholipid molecules with various proteins embedded to form a mosaic
Fluid mosaic model
Modifies new polypeptide chains and sorts and packages proteins and lipids
Golgi complex
