cell organelles

• the nucleus is surrounded in a


  double membrane called a nuclear envelope
• what does the nuclear envelope contain


  nuclear pores
• what do all nuclei have


  nucleolus which assembles ribosomes
• the cytoplasm contains..


  vesicles which transport substances around the cell
• what are vesicles


  fluid filled sacs
• ribosomes are made up of..

  RNA and proteins
• the endoplasmic reticulum is made up of a system of..


  folded membranes
• the RER has.. attached to its membrane


  ribosomes
• what do ribosomes do in the RER


  produces proteins and glycoproteins and packages them into vesicles
• the SER..


  secretes lipids and carbohydrates and packages them into vesicles
• the Golgi apparatus is made up of..


  folded membranes
• what do vesicles from the ER do at the Golgi apparatus


  bind to the Golgi which modifies these molecules into vesicles so they arrive at the correct destination
• enzymes in the Golgi apparatus..


  fill vesicles to form lysosomes
• lysosomes contain..


  digestive enzymes
• example of a digestive enzyme


  lysozymes which break down the cell wall of bacteria
• the mitochondria is made up of..


  outer and inner membranes
• the inner membrane of the mitochondria forms


  cristae
• the mitochondria is the site of


  aerobic respiration
• the mitochondria produces..


  ATP which is needed for the movement of vesicles
• the mitochondria contains a


  matrix which contains ribosomes and DNA
• plant cells, algae and fungi have..


  cell walls and a permanent vacoule
• the cell wall makes the cell


  rigid and is needed for turgidity
• the permanent vacuole..


  stores sugars and amino acids
• plant and algae cell walls contain

  cellulose
• fungi cell wall contains


  chitin
• chloroplasts are surrounded in a

  double membrane chloroplast envelope
• chloroplasts are filled with 


  thylakoids which contain chlorophyll and make grana
• chlorophyll is essential for


  photosynthesis
• grana is found in


  the stroma
• the stroma contains


  DNA, starch grains, ribosomes
