100
Partly decayed organic portion of the soil.
What is humus?
100
The surface layer of Earth's crust, consisting primarily of fragmented and weathered grains of rocks.
What is soil?
100
This promotes root growth.
What is Auxin?
100
The devision of the cell nucleus resulting in two daughter nuclei, each with the same number of chromosomes as the parent nucleus.
What is mitosis?
100
Creates four daughter cells that are haploid.
What is meiosis?
200
The 2n, spore-producing stage in the life cycle of a plant.
What is sporophyte?
200
They ingest soil and obtain energy raw materials by digesting humus.
What are worms?
200
Plant hormone involved in cell division and delay of senescence (aging).
What is Cytokinin?
200
Interphase, prophase, metaphase, anaphase, and telophase.
What are the five phases of mitosis?
200
The stage where sister chromatids separate.
What is anaphase II?
300
Members of a chromosome pair that are similar in size, shape, and genetic constitution.
What are homologous chromosomes?
300
Composed of litter, animal dung, the remains of dead plants, animals, and mircroorganisms.
What is organic matter?
300
A gaseous hormone involved in growth and development, including leaf abscission and fruit ripening.
What is Ethylene?
300
G1(First gap phase), S (Synthesis phase), G2 (Second gap phase), and M phase(Mitosis and cytokinesis).
What are the phases of interphase?
300
This causes genetic recombination.
What is crossing over?
400
Organic compounds that act as chemical signals between cells.
What are hormones?
400
40% sand 40% silt 20% clay
What is ideal agricultural soil?
400
This is involved in growth and development, including dormancy and responses to stress.
What is Abscisic Acid?
400
Stage where sister chromatids separate.
What is anaphase?
400
Stage during which spindle mircotubles are formed and chromosomes line up.
What is metaphase I and II?
500
The structure that forms during cytokinesis in plants, separating two daughter cells produced by mitosis.
What is cell plate?
500
It is 4 to 8 pH.
What is the pH of most soils?
500
This helps Auxin with apical dominance.
What is Gibberellin?
500
stage where chromatin condenses into chromosomes, each consisting of two chromatids attached to centromeres.
What is prophase?
500
The physical association of homologous chromosomes during prophase I of meiosis.
What is synapsis?
