Prokaryotic and Eukaryotic Flashcards
Two Types of Cellular Organisms
- Prokaryote
2. Eukaryote
Absence of a nucleus
Absence of membrane enclosed organelles
Unicellular organisms
Prokaryote
Presence of a nucleus that contains the cell’s genetic materials
Presence of membrane enclosed organelles with specific functions
Mostly multicellular except for unicellular euglena, paramecium and amoeba
Eukaryote
A large class of about 250 bacteria species with no specific structure but are classified into three types based on the substance they create and the environment they live in
Archaebacteria
Produce methane
Methanogens
Want salty environments
Halophiles
Attracted to heat
Thermophiles
Constitute the most number of species and possess rigid cell walls with peptidoglycan that can either be motile or non-motile Disease-causing bacteria belong to this type.
Eubacteria ( true bacteria)
they exhibit both animal-and plant-like traits‒flagella tails for movement and the presence of green chloroplasts for photosynthesis
Euglena
known for its ciliated structure that has become the favorite model organism of scientists for their researches
Paramecium
Have transparent cell walls made of silicon dioxide hydrated by water
Diatoms (“gems of the sea”)
A very big family that consists of yeasts, molds and mushrooms
Fungi
World of plants
Plantae
Characterized by their blade-like pointed leaves that grow very tall and serve as primary sources of carbohydrate foods
Oryza Grass Group
The biggest phylum in the plant kingdom. Flower Bearing.
Angiospermae Group
Also seed-bearing plants
Gymnospermae Group
The largest group composed of millions of species that are characterized by their motility, adaptation/survival mechanisms and predation
Animalia
