eukaryotic cells

• Cell membrane


  Single layer that is the external layer in animal cells
• Rough endoplasmic reticulum (rER)

  Folded membranes with ribosomes attached on the outside, site of protein synthesis
• Golgi apparatus

  Slightly curved folded membranes, where proteins are processed, packaged and modified
• Cytoplasm

  Jelly-like substance inside the cell
• Lysosomes

  Vesicles/bags containing digestive enzymes, can break down pathogens or dead cells
• Ribosomes

  Small organelles made of proteins and rRNA, site of protein synthesis
• Smooth endoplasmic reticulum (sER)

  Folded membranes without ribosomes, site of lipid and carbohydrate synthesis and storage
• Mitochondria

  Double membrane organelle, site of aerobic respiration and ATP production
• Vacuole

  Fluid-filled sac in plant cells, provides structural support, stores substances
• Chloroplasts

  Double membrane organelle in plant cells, site of photosynthesis
• Cell wall

  Outer layer in plant and fungal cells, provides structural strength
• Plasma membrane

  Phospholipid bilayer that controls what enters and exits the cell
• Nucleus


  Contains DNA, site of transcription and replication
