The most primitive cells are prokaryotic. They are simple, with no organelles and no nucleus. Animal and plant cells are eukaryotic, but they express some differences such as the cell wall, chloroplasts, or centrioles.

---------------------------------------------

<u>BACTERIA CELLS</u>

  • Bacteria are prokaryotic cells.

  • Prokaryotic cells lack a nucleus, nucleolus, and organelles.

  • They only present plasmids, ribosomes, and genetic material in their cytoplasm.

  • DNA not surrounded by membrane

  • They have a cell wall that protects the cell and a cell membrane that surrounds the cytoplasm. Some of them can also present a capsule.

  • Some of them have flagellum.

  • These organisms are capable of inhabiting places with e<em>xtreme temperature, salinity, acidity, or pH, among others. </em>

<u>ANIMAL </u><u>AND </u><u>PLANT CELLS</u>

  • Both the animal and plant cells are eukaryotic.

  • They carry their genetic material in the nucleus and mitochondria.

  • Organelles are located in the cytosol, and both of them are surrounded by a protector cell membrane.  

However, they have some differences:

⇒Cell wall : <em>A </em><em>rigid structure</em><em> that provides </em><em>support </em><em>and </em><em>protection</em><em>.</em>

• Animal cells do not have a cell wall. They are only surrounded by the cell membrane, which is flexible so they can adopt different shapes.

• Plant cells have a wall, so their shape is usually prismatic and regular. The cell wall is composed mainly of cellulose.

⇒ Chloroplast: these are organelles that accumulate chlorophyll.

• Animal cells do not have chloroplasts because they do not photosynthesize.

• Plant cells have chloroplasts, and they are in charge of the photosynthesis process that allows plants to release oxygen. These organelles use solar light as the source of energy.

⇒ Vacuoles:  

• Animal cells have many and small vacuoles whose function is to store water, ions, and waste intracellular substances.  

• Plant cells have a unique big-sized vacuole that might occupy almost 90% of the cell. Their principal function is to store water and keep the turgidity. When the vacuole gets empty, the plant loses rigidity.

⇒ Other differences are:

  • The animal cell has centrioles, while the vegetable cell does not.  
  • Plasmodium, chromoplasts, and glyoxysomes are present in the vegetable cell but not in the animal cell.

Ecosystems have lots of various dwelling organisms that interact with each differently. The living organisms in an environment may be divided into three categories: producers, consumers, and decomposers. they're all important elements of an atmosphere.

All ecosystems require strength from an outside source – that is usually the sun. An atmosphere ought to comprise manufacturers, customers, decomposers, and useless and inorganic count. All ecosystems require power from an external supply – that is generally the sun.
