1. The electron microscope has been particularly useful in studying prokaryotes‚ because electrons can penetrate tough prokaryotic cell walls. ~prokaryotes are so small. prokaryotes move so quickly they are hard to photograph. their organelles are small and tightly packed together. 2. Which of the following terms is most closely associated with "resolving power"? ~Clarity Larger size Greater color Lighter image 3. The person who first used the term cell to describe the basic

CHAPTER 1 Cell Structure and Organisation Cells * All living organisms are made up of cells * The simplest living organisms have one cell only * His name is unicellular-e.g. bacteria. * Most other living organisms have many cells- his name is multicellular- e.g. Man‚ plants‚ animals. * Cells can be seen only under microscope Cell structure All cells have the following structure in common: a) Cell membrane- a very thin layer of protein and fat‚ surrounding the cell.

Cell Similes (Part two) Mitochondria: The solar panels in Camp Half-Blood take energy from the sun and transform it into electrical energy that the camp can use to power it’s facilities‚ just as the mitochondria uses the nutrients in the cell from the food we eat and transforms them into ATP‚ the chemical energy used in cells. Ribosomes: The campers do the “work” of the camp by creating the swords in the forge‚ and are often found all around the camp grounds‚ in the forge‚ and fixing the solar

Bottom dwellers refers to any species of animal or some other organism that lives on the sea floor. Biologists often use the term benthos to refer to bottom dwellers. Benthos feed off algae. Examples include many species such as crab rock-fish worms sea slugs sea snails. Sea cucumber Starfish Crayfish coral Some Bottom dwellers clean the ocean floors Bottom dwellers refers to any species of animal or some other organism that lives on the sea floor.
