Characteristics of life Flashcards
(35 cards)
made of cells
unicellular/multicellular
all cells contain……
DNA
growth, development, and reproduction
growth-increase in size/number of cells
development
increase in efficiency
adapt and evolve-occursthrough process of growth
occursthrough process of growth
adapt and evolve pt2
the ability to thrive in a constantly changing environment, and the ability to learn new information and skills
reproduction
producing offspring that are biologically or genetically similarto the parent organism
asexual reproduction
dividing of cells during mitosis
sexual reproduction
the release of haploid gametes that fuse to produce a zygote with characteristics contributed by both of the parent organisms
mitosis
a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parents
meiosis
special type of cell division of germ cell is sexually-reproducing organisms that produces the gametes, such as sperm
sensitivity
external change that causes a response
response
reaction to a stimulus
homeostasis
ability to maintain internal stability
examples of homeostasis
when body begins to heat we release heat through sweat
when we begin to freeze body begins to vibrate in an attempt to produce heat
Nutrition
all living things obtain retain nutrients
ATP-source of energy for use and storage at cellular level
methods of obtaining energy
autotrophs
photosynthetic
heterotrophs
herbivores
omnivore
carnivore
autotrophs
create their own food
photosynthetic
se sunlight to make food(glucose)
heterotrophs
must consume their food
herbivores
eat plants
omnivore
eat meant/plants
carnivore
eat meat
respiration
ability to exchange gases with the environment (not breathing)
