Lesson 10: Unicellular Organisms

 

Unicellular Organisms Defined:

Unicellular organisms are composed of a single cell, unlike multicellular organisms which are made of many cells. This means they each live and carry out all of their life processes as one single cell. Most unicellular organisms are microscopic;

• Also called microorganisms or microbes since they are only visible under a microscope.
• The single cell is responsible for feeding, digestion, excretion and reproduction.
• Some microorganisms make us sick, but without the others we could not survive.
• The following are examples of unicellular organisms:

• • Bacteria
  • Protists
  • Some Fungi

Multicellular Organisms Defined: 

A tissue, organ or organism that is made up of many cells is said to be multicellular. Animals, plants, and fungi are multicellular organisms and often, there is specialization of different cells for various functions. In contrast, unicellular, or single-celled organisms are much smaller in size and less complex as they are composed of just one cell that senses its environment, gathers nutrients and reproduces asexually. The following are examples of multicellular organisms: human beings, organs and tissues,  plants, animals, birds and insects. 

~Generally speaking, we can say that unicellular and multicellular organisms are alike in that they exhibit all the functions of life, such as metabolism and reproduction, they contain DNA and RNA, they can exhibit a wide range of lifestyles, and they are essential to almost every ecosystem that we currently know of.

The paramecium are the larger protists, the amoeba are the blob-like protists, and the euglena are the smaller unicellular organisms.

• • Atoms are made of extremely tiny particles called protons, neutrons, and electrons.
  • Protons and neutrons are in the center of the atom, making up the nucleus.
  • Electrons surround the nucleus.
  • Protons have a positive charge.
  • Electrons have a negative charge.
  • The charge on the proton and electron are exactly the same size but opposite.
  • Neutrons have no charge.
  • Since opposite charges attract, protons and electrons attract each other.
