Living Things
What are the four needs of living things
Food, water, space and homeostasis.
What living things are eukaryotic? What are prokaryotic?
Prokaryotic - bacteria
Eukaryotic - protists, fungi, plants, animals
What are autotrophs?
Organisms that make their own food such as plants
Name three invertebrates.
Sponge, jellyfish, bugs, spiders, starfish, snails, worms
What is classification?
The process of grouping things based on their similarities.
What is homeostasis?
The condition in which an organism's internal environment is kept stable is spite of changes in the external environment
What are parasites?
organisms that benefit from living with, on, or in a host
What are stomata?
Small openings that plants use to take in or release carbon dioxide, oxygen and water.
What are the five groups of vertebrates?
Fish, amphibians, reptiles, birds, mammals.
What is the broadest level of classification?
What is Domain.
What are the characteristics of living things?
Made of cells
Contain similar chemicals
Use energy
Respond to surroundings
Grow and develop
Reproduce
What are hyphae? How do fungi reproduce?
Thread-like structures that allow fungi to absorb nutrients.
Spores
What are vascular plants?
plants with vascular tissue
grow tall
have large root systems
have a cuticle
What is the difference between ectotherms and endotherms?
Ectotherms are cold blooded. Endotherms are warm blooded
What is natural selection?
The idea that some organisms are better adapted to their environment than others.
The better adapted animals are more likely to survive and reproduce, passing down these better adapted traits to their offspring.
What are tissues?
A groups of similar cells that perform a specific function
What makes viruses living or nonliving?
Viruses are not cells
They cannot reproduce on their own
They do not use food or energy to grow
They do not respond to their surroundings
They do not produce waste
They do contain DNA
What are nonvascular plants?
Low growing plants that lack vascular tissue for transporting materials
No roots
No cell wall
Cannot grow tall
Name the three types of turtles.
Sea turtle, land turtle, and tortoise
What is common ancestry?
Certain organisms are similar because they share a common ancestor.
What are organs? What are organ systems?
body structures composed of different kinds of tissues that work together.
A group of different organs that work together to perform a task
How do virus kill other cells?
It then enters the host cell, or injects its DNA into the host cell.
The virus DNA takes over and forces the cell to make more copies of the virus
The cell then burst open releasing many new healthy viruses
What cell parts of plants are not found in animal cells?
large vacuole
chloroplasts
cell wall
Finish the sentence.
Animals are best adapted for...
The environment in which they live.
What is convergent evolution?
Unrelated organisms evolve similar characteristics
