Human Cell Structure

Partially permeable membrane that controls entry and exit of the cell

Contains DNA and is the site of of DNA replication (and transcription)

Double plasma membrane that surrounds the nucleus & contains pores for mRNA movement

Spherical structure in the Nucleus where RNA and ribosomes are synthesised

A stack of membrane sacs where proteins, carbohydrates & lipids are modified and transported

Site of aerobic respiration (& production of ATP)

Double membrane sacs that extend to the nucleus envelope to allow ribosomes to attach for protein synthesis

Double membrane sacs extending to the nucleus envelope to the site of lipid & carbohydrate storage and transport

Site of protein synthesis, made up of proteins and RNA

A network of proteins which provide structural support & allow molecules/organelle to move in and out of the cell

Contains hydrolytic enzymes (produced by golgi apparatus), membrane bound

Water based jelly like substance found in the cell where most chemical reactions occur

The downhill movement of molecules or ions down a concentration gradient across a membrane

The downhill movement of larger ions/molecules down a concentration gradient across a membrane through the use of protein carriersor channel proteins

The uphill movement of ions/molecules across a membrane against the concentration gradient using energy (from the hydrolysis of ATP)

The downhill movement of water molecules across a semi-permeable membrane down the concentration membrane

When the cell membrane engulfs material, to bring it into the cell inside a vesicle

When a vesicle is fused to the plasma membrane to allow molecules to be released from the cell
