Study of life Flashcards
All living things are made of ?
Cells
DNA holds what?
Instructions & DNA units of heredity
Genetics =
Study of genes
Mutation=
Genes hold characteristic for gene, when it changes it is called a mutation
Nutrition ) Character of life
take in digest, absorb, eliminate
Autotroph
manufacture their own food
Heterotroph
get food from other sources
Metabolism
lifes vital process
Photosynthesis
plants algae .. covert sunlight with energy making their on food
Photosynthensis Formula
CO2 + H2O—> CHO + O2
Carbon Dioxide, Water Soil, Sun, Carbohydrates, Oxygen
Aerobic Respiration
- cell takes place in presence of oxygen & produces energy
- in eukaryotic cells
Respiration Formula
CHO+O2–> CO2+H2O
Carbon Dioxide + Oxygen turns into Carbohydrates & water
Asexual
Common in plants
genes from one parent
offspring are clones
Sexual
Genes from two parents
Fusion of gametes (sperm/eggs)
Internal Reproduction
Egg Sperm Zygote 46 chromosomes Embryo
Single celled/ Uni-cellular
Microscopic
Include Fungi, bacteria, protists
Multicellular
Plants Animals .. Each cell does a different task
Cell Organization Levels
Cells, Tissues, Organs, Organ Systems, Organism
Prokaryotic Cells
small, less complex (ex:bacteria), no nucleus
Eukoryotic Cells
larger, more complex, contains organelles, (ex:plants animals fungi)
Kingdoms PCOFGS
Phyla, Class, Order, Family, Genera, Species
Taxonomy
a science of identifying, naming, and classifying organism
Scientific Name
two parts- scientific name & second identifies species
