Science test Prep 2
An identical genetic copy of an organism
Clone
Asexual reproduction method where a single cell copies its DNA, then divides
Binary Fission
Asexual reproduction method where a small clone forms on an organism and then breaks off when mature
Budding
Asexual reproduction method where an organism is cut in half and it regenerates into two new organisms
Fragmentation
A reproductive cell that will develop into a clone
Spore
Asexual reproduction method where a plant sends out extensions from the stem and forms a new plant.
Vegetative reproduction
Tissue in plants that can become leaves, stems or roots
Meristem
A piece of a plant that will grow roots
Plant Cuttings
Attaching a stem to another stem

Egg
The process of gametes meeting up and combining
fertilization
The cell formed when a sperm fertilizes an egg

Marsupial

Variation
explain how cloning plants using cuttings works. These words should be part of your explanation: meristem, activate, mitosis, roots
Cut the plant to activate meristem into starting mitosis and grow roots
explain how grafting works
Cut a slit in planyt and instert cutting from another plant. They will grow together
Know the story of navel oranges
Mutation occured causing them to be extra sweet and seedless. They must be grafted to grow more
