Cells

• All living things are made of cells.
• Cells are either prokaryotic or eukaryotic.
• Eukaryotic cells are complex and include all animal and plant cells.
• Prokaryotic cells are smaller and simpler, e.g. bacteria.
• Eukaryotes are organisms that are made up of eukaryotic cells.
• A prokaryote is a prokaryotic cell.
• Animal cells have a nucleus, mitochondria, cytoplasm, cell membrane, and ribosomes.
• Ribosomes are where proteins are made.
• The cell membrane holds the cell together and controls what goes in and out.
• the cytoplasm is a gel-like substance where most of the chemical reactions happen. It contains enzymes that control the chemical reactions.
• Nucleus contains genetic material that controls the activities of the cell.
• Mitochondria is the site of aerobic respiration. Respiration transfers energy that cell needs to work.

  A) cytoplasm

  B) nucleus

  C) cell membrane

  D) mitochondria

  E) ribosome

  
• Plant cells have a rigid cell wall, a permanent vacuole, and chloroplasts.
• A plant cell wall is made of cellulose. It supports the cell and strengthens it.
• A permanent vacuole contains cell sap (a weak solution of sugar and salts)
• Prokaryotes have a cell membrane, cell wall, cytoplasm, plasmid and circular strand of DNA.
