A cell is the basic unit of life, and all organisms on earth are made up of cells. The animal cell is a member of the Eukaryotes, which are complex multi-cellular organisms(Eukaryote). This type of cell is also enclosed within a membrane. Animal cells can come in different shapes depending on how they are covered…
Nucleus: Contains most of the genetic info in the eukaryotic cell (some genes are located in mitochondria and chloroplasts) Contains 1 or more nucleolus surrounded by nuclear envelope Nuclear envelope: a double membrane that encloses the nucleus separating its contents from the cytoplasm. Nucleolus – appears as a mass of densely stained granules and fibres…
About 100 years ago, scientists came up with a term for the smallest piece of matter: the atom. The word atom comes from the Greek word “atomus” which means “indivisible.” – Since scientists didn’t have very good laboratory equipment over one hundred years ago, they were slightly mistaken about atoms. The atom is the smallest…
DNA: DNA is the genetic information or blueprint of who and what we are, and how we operate. This genetic information is devoted to the synthesis of proteins, which are essential to our body. Proteins are created from templates of information called genes in our DNA. The Code: – DNA molecules are long polymers of…
Below is a table that compares the differences in cell structure between eukaryotic and prokaryotic cells. Criteria Type of Cell Prokaryote Eukaryote Nucleus? No Yes Internal membranes? No (no organelles) Yes (membrane bound organelles) DNA Single chromosome; ring Many; linear Reproduction method Asexual (binary fission) Asexual and sexual Size Small 10 times as large as…
