What is a weed?
A plant that is growing where it is not wanted
____ is a process which does NOT involve meiosis, fertilization or syngamy.
Asexual
What is an organelle?
A specialized part of a cell with a particular function
Sister chromatids are pulled apart by the spindle fibers and move towards opposite poles of the cell. What phase is this?
Metaphase
Who explored plant breeding with pea plants?

What two types of pollination could occur on a sexual reproducing plant?
Cross-Pollination or Self-Pollination
Process genetic instructions to create proteins. Floats freely in the cytoplasm
Ribosomes
What is crossing over?
When Genetic material is randomly swapped while chromatids are paired
Inheritance of one trait does not influence the inheritance of another traits is the...
Law of Independent assortment
Carrot germinates in the first year, survives the winter in a vegetative state, then flowers, produces seeds in the second year, and dies. What lifecycle is this
Biennial
This structure is an underground horizontal stem. It is used in asexual reproduction
Rhizome
This organelle packages molecules to be transported out of the cell
Golgi Apparatus
What does S phase stand for and what happens during this phase?
Synthesis - DNA is replicated so each chromosome consists of two identical sister chromatids.
An individual has two different copies of an allele for a gene. It is a ______________ genotype
What percentage of all plants are vascular plants?
80%
Reproduction which creates new plants from tissue or organs of the parent plant. Done by cuttings, layerings and grafting.
Induced Propagation
What is the photosynthesis equation?
6CO2 + 6H2O + Sunlight --> C6H12O2 + 6 O2
Prophase - Chromosomes condense and become visible, the nuclear membrane breaks down, and spindle fibers begin to form.
Anaphase - Chromosomes line up at the equator of the cell.
Metaphase - Sister chromatids separate and move to opposite poles.
Telophase - Chromosomes decondense and nuclear membranes reform.
Cytokinesis - The cytoplasm divides, forming two identical daughter cells.
The principle that alleles controlling traits are separated into reproductive cells during meiosis is called the Law of ______________.
Law of Segregation
