A long DNA molecule with genetic information for the organism
What is a chromosome
The stage where the chromosome lines up on the equator or the middle of the cell
What is Metaphase/stage 2
The stage where crossing over takes place
What is prophase 1/stage 1?
The process by which plants are artificially reproduced from the cells of the parent in a lab
What is tissue culture?
a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding
What is a species?
The feature that links sister chromatids together
What is the centromere?
The stage where the sister chromatids are pulled apart to either ends of the cell
What is anaphase or stage 3?
The set of chromosomes that come from the mother and the father which have the same sequence of genes along each strand
What are homologous pairs?
region of cells capable of division and growth in plants.
What is the meristem?
Process where humans select for desirable traits in agricultural products or animals
What is artificial selection?
A cell or organism with a has paired chromosomes
What is diploid?
The stage where two nuclei of the same genetic information are formed
Telophase/stage 4
The process by which genetic information is exchanged between homologous pairs
What is crossing over?
The process by which part of the shoot of plants are cut, then planted in the soil
What is cutting?
a process by which a population retains those genes which makes it adapted to its habitat
What is natural selection?
each of the two threadlike strands into which a chromosome divides longitudinally during cell division
What is a chromatid?
The sstage where the chromosomes are condensed and visible and the nuclear envelope disappears
What is Prohphase?
Cells produced in the reproductive organs that contain the haploid number of chromosomes
What are gametes?
The process of making an exact copy of an individual
What is cloning?
how species experience heritable changes in their traits over time
What is evolution?
Each of a pair of minute cylindrical organelles near the nucleus in animal cells, involved in the development of spindle fibres in cell division
What is a centriole?
section of DNA that codes for a specific protein, the basic physical and functional unit of heredity
What is a gene?
The process by which cells divide to create gametes
What is meiosis?
The act of placing a portion of one plant into or on a stem, root, or branch of another in such a way that a union will be formed and the partners will continue to grow.
What is grafting?
