Levels of Organization
What is the smallest unit of life?
Cell
The process by which living things make more of their own kind.
Reproduction
The genetic material found in all living organisms is called:
DNA
Rigid outer layer in plant cells that provide support and protection
Cell wall
Human cells have a cell wall to protection (T/F)
False
A group of similar cells working together is called this.
Tissue
The increase in size and complexity of an organism over time.
Growth and development
A plant begins as a seed and adds new cells.. this is called:
growth and development
Layer that allows nutrients to enter and waste to exit the cell
Cell membrane
Plants have both mitochondria and chloroplasts
True
Different tissues working together is called:
An organ
The ability to detect and respond to changes in the environment.
Responding to stimuli
The process by which species change over time to better suit their environment.
Adaptation or Evolution
Jelly-like substance that fills the cells and holds organelles in place
Cytoplasm
Ribosomes are the storage organelles
False
Multiple organs working together:
System
The maintenance of a stable internal environment in an organism.
Homeostasis
A dog smells food and begins to produce extra saliva that will help it digest the food. This is called:
Respond to stimuli
Organelle that produces food through photosynthesis
Chloroplast
Prokaryotes
Multiple organ systems working together form an:
Bacteria developing new species that can resist antibiotics is called:
Evolution (Adapt to their environment and evolve over time)
You sweat when it is hot so that you can maintain a safe body temperature. This is called:
Homeostasis
Storage organelles, larger in plants
Vacuole
Prokaryotes cannot reproduce (T/F) and why/how
They can reproduce by cloning: Duplicating the genetic material then splitting the cell
