The longest phase; the "regular life of the cell"; at some point during this phase, the cell gets a signal to copy DNA.
What is Interphase?
100
The purpose of mitosis.
What is the creation of new cells by cell division?
100
The union of sex cells.
What is fertilization?
100
Male part of the flower that lifts pollen higher making it more likely for it to be picked up by a pollinator.
What is the filament?
100
The movement of pollen from the anther (male structure) to the stigma (female structure); necessary for sexual plant reproduction.
What is pollination?
200
The cell membrane pinches and everything is put back together. The nuclear membrane forms. Chromosomes loosen back into DNA. The spindle fibers dissolve.
What is Telophase?
200
Results in offspring, but only requires one parent and results in no genetic variation in offspring.
What is asexual reproduction?
200
The sex cells of plants.
What are pollen and ovule?
200
Makes pollen.
What is the anther?
200
Scent, vocal calls, exotic plumage, dancing, and bioluminescence.
What are ways to attract a mate?
300
Spindle fibers pull chromosomes apart to opposite sides of the cell.
What is Anaphase?
300
When an organism grows a new individual from a part that has broken off.
What is regeneration?
300
The sex cells for animals.
What are sperm and egg?
300
Female part of the flower that consists of the stigma, style, and ovary.
What is the Pistil?
300
Mimicry, fruit, and colors.
What are ways plants can attract pollinators?
400
Chromosomes are lined up in the middle, the spindle fibers reach across the whole cell and there is no membrane.
What is Metaphase?
400
Requires the DNA from two parents and results in genetic variation in offspring.
What is sexual reproduction?
400
Species that have few offspring and give lots of parental care.
What is K-selected?
400
Becomes a seed after fertilization.
What is the ovule?
400
This environmental factor may cause plants to grow sideways instead of straight.
What is wind?
500
Spindle fibers pull chromosomes apart to opposite sides of the cell.
What is Prophase?
500
The three parts of Cell Theory.
What is a) all living things are made of cells, b) cells are the building blocks of life, c) all cells arise from other cells.
500
Development occurs in an egg outside of the animal's body.
What is external development?
500
The long tube which pollen travels through to meet ovules in the ovary.
What is the style?
500
This determines gender in turtles and alligators when the organisms are in developing in the egg.
