Classification system and concepts of living things
What is abiotic and biotic?
Abiotic: not alive
Biotic: alive
A cell with no nucleus.
Prokaryotic cell
Contains genetic materials
Nucleous
The basic unit of life.
Cells
How can we battle bacterias?
Antibiotics
What is the broadest level of classification in taxonomy? (Biggest)
Domain
A cell with define nucleus and more complex organelles.
Eukaryotic cell
What does a ribosome do
Is the principle organelle that makes proteins
What is a NEED for organisms to live?
Homeostasis
Food
Shelter
Water
Describe some of the structures that bactearias has
Flagella for movement
Pili for reproduction
Capsule
DNA
Ribosomes
Cell wall and membrane
What is an autotroph?
Organism that can create their own food
Two difference between animal cell and plant cell
1. Plant cell has cell wall
2. Plant cell have chloroplasts
3. Plants cell are rectangular while animal cells are circular
4. Vacuoles in plant cells are bigger.
The organelle responsable of making energy
Mitochondria
What does an unicellular organism means?
Composed of one cell and it does all the functions.
How to bacterias obtain food?
What is heterotroph?
An organism that hunts or looks for their own food
Oldests and most abundants cells of Earth
Prokaryotic cells
What does the golgi apparatus do?
It package and delivers proteins. "Amazon"
What characteristic is responsable that we react to something hot? (Like putting your hand on the stove)
Stimuli and response
Explain what binary fission is.
Asexual reproduction of the bacteria. From one cell it duplicates and creates two identical cells.
What part of taxonomy classification does scientists use to name organisms.
Genus and specie
Name one of the three principles of cell theory
1. All living organisms are made of cells.
2. Cells can only by produced by other cells.
3. Cells are the basic unit of organisms
Describe the diference between Rough Endoplasmic Reticulum (RER) and Smooth Endoplasmic Reticulum (SER)
The RER has ribosomes and makes proteins.
The SER doesnt has ribosomes and makes other chemicals like lipids.
Name atleast 3 of the 7 characteristics.
They are made up of cells
They contain similar chemical
They use energy
Respond to their surroundings
All organisms grow
All organisms develop
All organisms reproduce
What mechanisms does a bacteria do to survive on harsh enviroments?
They create a thick wall around their genetic material and cytoplasm called endospore.
