Multicellular Organisms: Artificial Vegetative Propagation Flashcards
Artificial vegetative propagation is?
Artificial vegetative propagation is the process of creating copies of plants through human intervention.
Examples of artificial propagation
Cutting and grafting
Artificial propagation advantages
- Quicker than waiting for seed production
- All new plants are identical to the parent
What is a node
A node is a point of a stem from which one or more leaves or side branches grow. A node is a 🔥growth point🔥
What is Wounding
When a plant is wounded the cells at the site of thee would start to 🔥 divide and grow🔥
Example for wounding
If a plant is wounded by 🔥cutting🔥 below a node, the stem will begin to produce 🔥roots🔥
How to use Rooting power
The cut end can be coating with 🔥rooting🔥🔥power🔥before planting. The powder contains 🔥chemicals🔥 which encourage the cells at the cut surface to divide and develops unit roots
Water loss can be reduced by
- 🔥Removing🔥 some of 🔥lower leaves🔥
- Placing the cutting in a 🔥propagator🔥
Propagator is and use
A 🔥propagator🔥 provides a 🔥humid atmosphere🔥 to encourage root growth. The propagator can be a 🔥plastic bag🔥 or it can be a peice of 🔥electrical equipment with a heating and lighting system🔥
Taking a cutting - practical
- Full a pot with 🔥compost🔥
- Make a 🔥diagonal🔥 cut 🔥below🔥 the 🔥node🔥
- 🔥Remove🔥 the 🔥lower leaves🔥 to reduce water loss
- Dip the cut end into 🔥rooting powder🔥
- Make a 🔥hole🔥 in the compost. Place your cutting in the pot and 🔥firm down🔥 the compost
6.🔥Water🔥 the cutting - Place cutting a 🔥propagator🔥
What did grafting and how?
Grafting involves taking a cutting from a plant and attaching it on the stem of another plant
The cut surfaces of the two plants grow together
A plant variety that grows poorly but produces desirable products such as edible fruit can he grafted onto the stem it a plant grows well and has characteristics such as diseases resistance
