2.1 Eukaryotic Cells Flashcards
(27 cards)
Nucleolus
Production of ribosomes + control of growth + division
Rough ER
Covered in 80S ribosomes
Involved in production + transport of proteins
Smooth ER
No ribosomes
Involved in synthesis + transport of steroids + lipids
Golgi Apparatus
Modifies proteins + packages them into vesicles for transport
Lysosomes
Contains digestive enzymes
Cell Wall
Permeable wall around plant cells
Mainly made of cellulose
Chloroplast
Carries out photosynthesis
Tonoplast
Surrounds the vacuole
Vacuole
Fluid filled cavity surround by a membrane
80S ribosomes
Made up of rRNA + proteins
Site of protein synthesis
Centrioles
Hollow cylinders containing a ring of microtubules
Involved in Cell division
What makes up the nucleus
nucleolus
nuclear envelope
chromatin
nucleolus
Pure DNA + proteins found here
Production of ribosomes + control of growth + division
Chromatin
Mixture of DNA + proteins that form chromosomes
Nuclear Envelope
Double Membrane
Has pores which allow molecules to leave the nucleus
What makes up the mitochondria
Outer Membrane
Inner Membrane
Matrix
Ribosomes
Cristae
Outer Membrane
Allows the movement of ions in + out of the mitochondria
Inner Membrane
Contains the ETC
Matrix
Contains enzymes for cellular respiration
Ribosomes
Where protein synthesis takes place
Cristae
Provides a larger SA for aerobic respiration
What organelles are used in protein transport
Rough ER
Golgi Apparatus
Vesicles
Protein Transport in Rough ER
Ribosomes synthesise proteins
Vesicles transport the proteins + fuse with flattened discs of Golgi
Protein Transport in Golgi
Cisternae in Golgi modifies the proteins
