Science fair project, plant biology?

Question

He guys i have a science fair in December i need some project ideas i love plants( flowers, fruit plants, etc.) So i` d like to plant biology. Thanks so much ( =

Answer 1

Arabidopsis is a fun plant to get into because its often used in research laboratories to study signal transduction and genetics. One cool thing that was actually discovered in these plants is the "A, B, C" model of flower development. Basically 3 genes, expressed in different combinations result in the proper or mutant development of sepals, petals, stamens, and carpels (all parts of the flower).

one thing you could do is purchase wildtype Arabidopsis and mutant(s) (ie. one "lacking" petals or stamens). Knowing the two genotypes, you could start crossing the two plants and calculating the probabilities of various genotypes or phenotypes of the offspring. Generations are really quick with these plants and you could cross lots of 'em really quickly.

an interesting title might be "validating Mendelian assumptions using the ABC model of floral development"

if you want to really sophisticated you could start mutating specific regions of DNA (or purchasing various mutants- the entire sequence is known) in regions of the promoter, enhancer, or other gene products for those 3 genes, begin crossing again, and see what pieces of DNA are most vital for maintaining wildtype phenotype. Not all nucleotides of each gene are necessarily necessary.

Answer 2

DiscoveryEducation.com has lots of ideas for Science fair projects.

Answer 3

the simplest of all is onion bulb. Put the roots in distilled water and let the roots grow. Take the tip of one root and smash carefully between 2 slides, add a drop of water and cover with a cover slip. Observe under high power microscope and u'll see cell division...MITOSIS process... in action.

Answer 4

my cousin is a total tree hugger and she likes grass so she did her science fair project on grass changeing colors

she put color die in the water she watered the grss with to see if it changes colors. it worked but for best results don't use blue, green, or yellow. use interesting colors like red

Answer 5

Steam powered toy car.
