2026/2027 TESTING CYCLE
what is the most important nutrient's main purpose for the plant? - CORRECT ANSWERS-
Nitrogen; helps to make the plant green (chlorophyll)
Describe the following propagation methods of air layering, tissue culture, stem cuttings, leaf cuttings,
root cuttings, & seeds. - CORRECT ANSWERS-Air layering is a method of propagating new trees
and shrubs from stems still attached to the parent plant. The stem is wrapped with damp moss to
encourage roots to form.
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs
under sterile conditions on a nutrient culture medium of known composition. It is widely used to
produce clones of a plant in a method known as micropropagation.
Stem cuttings: It involves taking a section of stem from a parent plant and manipulating it to create a
new plant.
leaf cuttings: stem cutting produces new roots, and a root cutting produces new stems
root cuttings: the portion of root is cut from a parent plant (often called a mother plant), placed in a
growing medium, and then left to grow its own system of roots and stems.
seeds: is the method of plant propagation (multiplying, reproducing, or breeding new plants) that is
done through the use of seeds.
What is germination vs propagation - CORRECT ANSWERS-germination- seed sprouts
propagation- growing plants
Describe asexual plant propagation & sexual plant propagation. - CORRECT ANSWERS-asexual:
cuttings, layering, division, buddings, & grafting
sexual:involves the union of the pollen (male) with the egg (female) to produce a seed
Breakdown the spermatophyta category of plants & describe each sub level. - CORRECT
ANSWERS-Gymnosperm- cones, naked seeds
, Angiosperm- Flower parts (monocotyledons- first leaf, parallel veins, non-woody flowers * 3)
(dicotyledons- netted veins, woody, flowers *4 or 5).
describe the vascular system of a monocotyledon & dicotyledon - CORRECT ANSWERS-monocot-
vascular bundles
dicot- organized
What are the 3 vegetative parts of the plant & what are their main function? - CORRECT
ANSWERS-leaf- photosynthesis
stem-support
root- water/ nutrients
what are the two types of roots? - CORRECT ANSWERS-tap & fibrous
list & describe 5 modified stems - CORRECT ANSWERS-Tuber: eyes, food storage, propagation
(growing plants), underground
Rhizome(turf grass, ginger): underground horizontal stem, food storage
bulb: with bulblets, underground, food storage
bulb with leaves: underground, food storage
cladophyl: stem that goes through photosynthesis, above ground
stolon( golf course grass): above ground, horizontal stem, photosynthesis
what is the reproductive part of the plant? - CORRECT ANSWERS-The flower is the reproductive
unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the
female reproductive organs), and stamens (the male reproductive organs).
What is osmosis? - CORRECT ANSWERS-is the passive transport of water across a selectively
permeable membrane in order to reduce a concentration difference of a solute between a concentrate
and permeate solution separated by the membrane
Name the cereal crops - CORRECT ANSWERS-Rice 2. Wheat, bread wheat 3. Durum wheat,
macaroni wheat 4. Corn or maize 5. Job's Tears, salay, adlay, tigbe, pawas 6. Barley 7. Millet 8. Sorghum
