Features of cells

Features of cells

1. Bacteria

   • plasmid DNA
     • extra circles of DNA. contains additional genes that are not found in chromosomes.
   • flagellum
     • to aid with movement.
   • chromosomal DNA
     • a single loop lies free in the cytoplasm. it carries most of the bacvterial genes.
   • cell wall
     • Used for protection, but made out of different substances to plant cells.
   • cell membrane

2. Plant

   • cell membrane
   • nucleus
   • cytoplasm
   • mitochondria
   • cell wall
     • used to protect the cell
   • central vacuole
     • stores nutrients for the plant cell to survive
   • chloroplasts
     • used in photosynthesis to convert the energy of the sun into sugars that can be used by cells

3. Animal

   • cell membrane
     • controls what enters and leaves the cell
   • nucleus
     • a large structure that contains DNA - instructions for the building and working of the cell
   • cytoplasm
     • jelly-like substance that fills the cell - many reactions take place here.
   • mitochondria
     • tiny structures where respiration takes place, releasing energy for cell processes.
