Science Final Flashcards
What are living things?
- have cells
- can reproduce
- can grow
- organized structure
- can be single or multicellular
How are organisms organized?
Into domains
What are the thre domains?
Bacteria, archaea, eukaryote
What are animals?
multicellular eukaryotic organisms
can move around
get nutrients from consuming other organisms
What phylum are animals apart of?
chordata
How do plants stay alive?
sun and soil
making food through photosynthesis
archaea
domain made of prokaryotes
live in extreme environments
Bacteria
domain of prokaryotes
cell wall
reproduce by cell division
Virus
nonliving
infectious particle
composed of nucleic acid and protein coat
can invade and destroy a cell
Fungi
eukaryotic organisms
cannot move
reproduce using spores
gest food by breaking down substances
Protista
kingdom of one-celled eukaryotic organisms
Gymnosperm
woody
vascular seed plant
seeds not enclosed by ovary or fruit
Cellular respiration
process by which cells use oxygen to produce energy from food
endosckeleton
internal skeleton made of bone and cartilage.
hibernation
period of inactivity and lowered body temperature that some animals undergo in winter
What happened during Precambrian time
life began to evolve on Earth
What provides structural evidence for evoluation?
similar bones in legs of human, dog and bat
Four parts of Darwin’s Theory
- overproduction
- Genetic variation
- Selection
- Adaptation
What is true about Protist?
Some can photosynthesize
Fungi that exist mostly in a unicellular state and reproduce by budding
yeast
Do archea have nuclei?
no
What is a task the host cell has during replication of viruses?
to replicate the virus’s genetic material
Where would you expect to see a plant that does not have a vascular system?
low and close to the ground
What is the phyla characterized by an exoskeleton and jointed legs
Arthropoda
What do you call the cycle of activity that an animal has during any 24 hour period
circadian rhythm
Describe an innate animal behavior
monarch butterflies migrating southward
The body system that controls growth, metabolism and regulates reproduction through body hormones
Endocrine system
System that includes the heart, arteries, capillaries, and veins
Circulatory system
This is a membrane-covered structure contains all of the materials necessary for life
cell
In this type of reproduction, a single partner produces offspring that are genetically identical to the parent
asexual repoduction
This is the difference in inherited traits an organism has from others of the same species.
variation
This is made up of fossils that have been discovered around the world
fossil records
What is the most recent classification system?
Domains
Bacteria, Archaea, Eukarya
