Big Idea 3

(Big Idea 3 #3) A eukaryote is a cell with an apparent nucleus, so every animal is a eukaryote, like this bird.

(Big Idea 3 #4) Double fertilization  is when two male gametes fertilize one female gamete, which happens most often with pollonating flowers.

(Big Idea 3 #8) Different alleles that code for the same trait usually ends up in incomplete dominance, or, as this rat shows, in codominance, which is the reason for the rat’s fur being white and black, but not a mix of the two.

(Big Idea 3 #8) This is an example of incomplete dominance, since two alleles coded for the same gene, you end up with different looking plants, such as these plants which are all the same type of plant but with different colored leaves.

(Big Idea 3 #8) This is another case of codominance since the petals are not one color or a blend of colors, but they are striped, and each different allele shows up.

(Big Idea 3 #9) Schooling in big groups is a way to be safe and keep away predators, as there are safety in numbers. These fish are all staying extremely close not only due to the close proximity of the tank, but because they want to be safe.

(Big Idea 3 #15) Mitosis is cell division, and is an essential part of life. Mitosis, or the cell cycle, happens within all of us.

(Big Idea 3 #17) A phenotype is the physical appearance of a plant or animal that it gets from its genetic makeup, for example all these flowers are the same but have different phenotypes. 

(Big Idea 3 #18) A pollinator is whatever transports pollen from male flowers to female flowers, in this case, it is this bee.

(Big Idea 3 #20) A plant's seed dispersal method is the method it uses to reproduce, like a cherry, which gets eaten by a bird and then has its seeds scattered by that bird.
