Theme 1- Properties of Life Flashcards
What are organisms?
Living things (0.1% alive today)
What are the eight properties of life?
- Order
- Reproduction
- Growth & Development
- Need Food & Use Energy
- Homeostasis
- Respond to the Environment
- Adapt to the Environment
- Made up of Cells that Contain DNA
- ORDER
a.) Is order abnormal in nature?
b.) How do you maintain order?
a.) It is abnormal in nature
b.) You must use food to produce energy and maintain order
- REPRODUCTION
a.) What does reproduction mean?
b.) What are the two types of reproduction?
a.) Reproduction means to make offspring
b.) Sexual and Asexual
a.) How does sexual reproduction work?
b.) How many parents are needed?
c.) Are the offspring unique or the similar to one another?
a.) A sperm and an unfertilized egg combine to make a fertilized egg
b.) Two parents are needed
c.) The offspring are unique
a.) What is one unfertilized egg called?
b.) What are many unfertilized eggs called?
c.) What is a fertilized egg called?
a.) Ova
b.) Ovum
c.) Zygote
a.) Does asexual reproduction require fertilization?
b.) Are the offspring unique or similar to one another?
c.) How many parents are required for asexual reproduction
a.) No
b.) The offspring are similar to each other
c.) Only one parent is required
What are the three types of asexual reproduction?
1.Binary Fission
2.Budding
3. Spore Formation
What is the definition of fission?
a unicell organism splits into two unicell organisms
What are two binary fission examples?
- Bacteria Fission- one cell multiplies its DNA and size then splits into two identical cells (Prokaryotic)
- Amoeba Fission- one cell multiplies its DNA and size then splits into two identical cells (Eukaryotic)
What four things do all cells have?
- DNA
- Ribosomes
- Cytoplasm
- Plasma Membrane
a.) What are two examples of budding?
b.) How do they fertilize?
a.) Hydra and Sponge
b.) They use cross fertilization
What is a hermaphrodite?
An organism born with both testes and ovaries that actually work
a.) How does spore formation work?
b.) Does fertilization take place?
c.) What is an example of spore formation?
a.) A unicell organism undergoes mitosis and becomes a multi cell organism
b.) No
c.) A spore turning into a mushroom
- GROWTH & DEVELOPMENT
a.) What does growth mean?
b.) What does development mean?
a.) Growth means to increase in size (Baby=> Adult)
b.) Development means all of the changes that occur during growth
What are the two types of metamorphosis?
- Incomplete
- Complete
a.) What is an incomplete metamorphosis?
b.) What are the stages?
a.) When an organism stays similar through changing (ex. dragonfly)
b.) 1. Egg
2. Nymph (molting)
3. Adult
a.) What is a complete metamorphosis?
b.) What are the stages?
a.) When an organism completely changes from one form to another (ex. butterfly)
b.) 1. Egg
2. Larva (eat as much as possible)
3. Pupa (undergo complete change)
4. Adult
- NEED FOOD & ENERGY
What are the two types of feeders?
Autotrophs and Heterotrophs
a.) What is a Autotroph?
b.) What is a Heterotroph?
a.) They make their own food using photosynthesis- using light to make glucose
b.) The can’t make their own food so they rely on other organism for energy
What is the equation for photosynthesis?
light+C6H12O6=====> C6H12O6+6CO2
What are the two types of heterotrophs?
- Consumers- ingest and digest food
- Decomposers- absorb nutrients
What are the three types of consumers?
- Carnivores- meat eaters
- Herbivores- plant eaters
- Omnivores- plant and meat eaters
a.) What is cellular respiration?
b.) What is the equation for cellular respiration?
a.) Using energy
b.) C6H12O2====>H2O+CO2+ATP
