Cell Membrane (Plasma Membrane) of Prokaryotes - Composed of phospholipid Envelope (prokaryotes) Cell Wall + Cell Membrane in prokaryotes How does one determine whether a cell wall is gram positive or gram negative? - Stain with crystal violet stain followed by counterstain w/ safranin- If envelop...
How is the plasma membrane of the prokaryotic cell folded and why? -Inward -creates folds for metabolic processes take place.. why are prokaryotic cells folded inwards? they lack organelles with membranes What is the average size of prokaryotic cells?
1. Is embedded in the phoslipid bilayer2. Is amphipathic (Has a hydrophilic and a hydrophobic portion)3. Helps maintain the integrity of the cell membrane Cytoplasm The cellular region between the nuclear and plasma membrane: composed of cytosol (fluid) and organelles Organelles 1. Endoplasmic re...
membrane Plasma contains antibodies that react against what foreign antigens leukocytes white blood cells what is the function of leukocytes protect against pathogens - crucial in body's defense against disease leukocytes have complete cells with what ...
- solid rods of actin - involved in cell movement and support ex: muscle contraction is based on interaction of actin with myosin in muscle cells - move materials across the plasma membrane in amoeboid movement Intermediate filaments - collection of fibers involved in maintenace of cytoskeletal inte...
plasma membrane A selectively-permeable phospholipid bilayer forming the boundary of the cells Ribosomes Makes proteins organelles A tiny cell structure that carries out a specific function within the cell Rough Endoplasmic Reticulum System of internal membranes within the cytoplasm. Membranes are rough du...
Cytoplasma in the soma is called the axoplasma plasma membrane of the Axon is called the axolemma Action potential Electrical impulses sent down the axon Terminal Arborization here the axon ends and branches out. Enlarged spots are called synaptic bulbs, knows, buttons, each is filled with neur...
transport leaked plasma proteins and fluids to the cardiovascular system The saclike initial portion of the thoracic duct is the cisterna chyli Entry of lymph into the lymphatic capillaries is promoted by which of the following? a. one-way minivalves formed by overlapping endothelial cells ...
these "bad" cholesterols deliver cholesterol to cells for membrane production. they're stick and stay in arteries high density lipoprotein these "good" cholesterols scavenge excess cholesterol to return to the liver where it is broken down and used as a building block; can be obtain from eating...
most commonly only has primary wall, maintain meristematic ability, involved in photosynthesis, storage, secretion. Ex: transfer cells: ___ cells with cell wall ingrowths that increase surface area of plasma membrane, facilitates movement of solutes over short distances. Found in solute transfer loc...
