Cells Flashcards
Parts of cell, Transport, make up of tissue.
Passive Transport
Requires no energy ( ATP ) Automatic. High to Low concentration
Osmosis
Diffusion of water over a semi- permeable membrane.
Diffusion
Movement of small uncharged soluble lipids from areas of high to low concentration. Down / with concentration gradient.
Facilitated Diffusion
Movement of large charged non soluble lipids from areas of high to low concentration via a channel protein. Down/ with concentration gradient
Active Transport
Requires energy ( ATP ). Low to High concentration
Carrier Protein
Moving of materials against the concentration gradient with the use of ( ATP ) energy and a integral protein. Ex) Na/ K pump
Cytosis
Endo/ Exocytosis the movement of material out/ into the cell using vesicles.
What is the most widely accepted model of cell membrane
Fluid Mosaic Model
Bilayer of cell membrane
Phospholipids
Nucleolus
The site of ribsomal DNA and assembly
Nucleus
Contains DNA contains pores to allow materials to pass through
Ribosome
protein builder
Vesicle/ Vacuole
Storage and transport
Rough Endoplasmic Reticulum
Has ribosomes. Factory to build proteins.
Smooth Endoplasmic Reticulum
Without ribosomes. Produces lipids and detox
