Characteristics of living things
The modern cell theory states that:
1. All living things are made up of cells
2. All cells come from other pre-existing cells
3.....?
The cell is the smallest living unit in any organism
Another term for living thing
Organism
Prokaryote lack...
Membrane-bound organelles
These key structures are only found in eukaryotic cells
Membrane-bound organelles
Rigid structure that surrounds the cell membrane and provide structures to prokaryotic cells like bacteria and eukaryotic cells like plant cells.
The cell wall
As baby penguin reaches adulthood, it increases in size and loses its brown fur to gain black and white fur.
Growth and Development
Any organism containing only one cell
Unicellular organism
All prokaryotes are...
Unicellular
This organelle, which contains DNA is the first organelle to evolve in Eukaryotic cells
The nucleus
This organelle is the second organelle to ever evolve in Eukaryotes. It is the power center of the cell and one of only 3 other organelles to carry a set of DNA
The mitochondria
All living things must obtain and process energy, this is called metabolism. These two terms refer to:
A: an organism that obtain energy from sunlight and inorganic compounds.
B: An organism that eat other organisms to obtain energy
A: Autotroph
B: Heterotroph
Any organism made up of more than one cell
A multicellular organism
This kingdom of organisms is considered the most ancient form of life on earth
Archae
The levels of organization in Eukaryotes
Cells make up tissues, tissues make up organs, organs make up organ systems and, organ systems make up organisms.
This organelle plays a role in cell division and is only found in animal cells
Centrosomes
The sum of all the self-regulating processes occurring within an organism to maintain its internal equilibrium.
Homeostasis
Eukaryotes not only contains unicellular organisms but also, unicellular organisms. Which kingdoms of organisms contain both unicellular and multicellular organisms?
Fungi & Protists
This jelly-like fluid is fills the space inside all cells and hold its structures including DNA in prokaryotic cells.
The cytoplasm
The 4 out of 6 kingdoms of life that are eukaryotes
Animals, plants, fungi and protists.
This protist is the only other organism aside from plants to have a cell or cells to contain a chloroplast.
Green Algae
What are the 8 characteristics of living things?
1) All living things are made up of cells. 2) All cells in a living contains DNA. 3) All living obtain and process energy. 4) All living things must maintain homeostasis. 5) All living things respond to internal/external stimuli. 6) All things things grow & develop. 7) All living things reproduce. 8) All living things evolve
all the cells in heredity, cellular organization, growth and development, response to stimuli, adaptation through evolution, homeostasis, and metabolism.
There are 2 groups of organisms divided into 6 kingdoms, what are they?
Bacteria, Archaea, Fungi, Protists, Animals & Plants
The 2 prokaryotic kingdoms out of the 6 kingdoms of life are...
Archaea and bacteria
These non membrane-bound organelles make proteins and are the only organelles found in both eukaryotes and prokaryotes.
Ribosomes
Why do the root cells of plants not have chloroplasts?
Their job is to collect water and nutrients. They do NOT carry out photosynthesis, which happens in the chloroplast
