uses cells to make more of itself

cell without a nucleus

cell that contains a nucleus

Regulates what enters and exits the cell

rigid outer boundary used for extra support in all organisms except animals

storage of the cell ("closet") - very large in a plant cell

site of cellular respiration

coils of DNA found in the nuclei of cells

makes proteins

site of photosynthesis

made in the ribosomes

waxes, oils, fats

instructions that are passed onto offspring

sugars and starches

made of a 5-carbon sugar, a phosphate group and a nitrogen base

sections of DNA that code for a protein

asexual cell division

chromosomes line up in the middle of the cell

chromosomes are pulled (apart) to opposite poles

cytoplasm is splitting in two, following telophase

cells dividing out of control; disruption of the cell cycle

takes place prior to mitosis

type of solution that will shrink a cell

type of solution that will make a cell swell

a balance; equilibrium

movement of molecules from higher concentration to lower concentration

diffusion of water

energy is not required in diffusion, osmosis, and facilitative diffusion

pairs with cytosine

pairs with adenine (DNA)

makes up the backbone of DNA/RNA

change in DNA

one nitrogen base replaces another

two different alleles (Tt)

the allele that always shows up in a pair

physical appearance of the trait

the allele that is hidden

alternate form of a gene (T or t)

when both alleles are the same (TT or tt)

cross between red and white flowers creates pink flowers

chromosomes arranged in homologous pairs

multicellular; no cell wall

does not have a nucleus

can photosynthesize; multicellular

some are like plants; some are like animals

mold and mushrooms

larger than order, smaller than phylum

larger than family; smaller than class

larger than genus; smaller than order

most specific

most general; largest category

smaller than family; larger than species

those most fit for the environment will have a better chance of survival

evolves (changes)

allows for natural selection

increases chance of survival; encoded in DNA

takes place in the chloroplasts of plant cells

takes place in the mitochondria

product of respiration, in addition to water

product of photosynthesis, in addition to oxygen

reactant of respiration, in addition to glucose

reactant of photosynthesis, in addition to carbon dioxide

made up of brain and spinal cord

glands release hormones

site of nutrient absorption

transports materials around the body

allows you to move

framework for your body

gas exchange

regulates body temperature

defends your body from pathogens

removes waste from body

organ in plant that does the majority of photosynthesizing

absorbs water for the plant

plant grows toward light

reproductive structure of the plant

moves water up the plant

roots grow down; stem grown up

tranports food from the leaves down to the roots where it is stored

kills and eats other organisms

first organisms to inhabit an ecosystem

required by all organisms

both organisms benefit in this relationship

can make their own food

amount of energy transferred to each trophic level

the organisms being harmed in a parasitic relationship

the development of an ecosystem over time

a relationship in which one organism benefits and the other is unaffected

tapeworm, flea, tick, etc.
