Budding
Definition of Budding
Budding is an asexual reproduction method in which a new organism develops from a bud of an existing organism
Definition of Vegetative Propagation
Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants
Definition of Binary Fission
Binary fission, asexual reproduction by a separation of the organism into two new daughter cells. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA
Definition of Spores
Spores are reproductive units or cells that germinate or develop into new individuals without fusion with other reproductive cells. They are single-celled enclosed by a cell wall. Spores do not have to fuse with another reproductive cell to produce a new individual, contrary to gametes
Definition of Regeneration
Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts. Regeneration occurs via mitosis. Lizards can regenerate their tails, star fish can regenerate their arms while humans have the ability to regenerate their liver to a certain extent
Budding often occurs when there are:
A: A small amount of nutrients available
B: No nutrients available
C: Large quantities of nutrients available
D: When the plant wants another plant
C: Large quantities of nutrients available
Where in the plant does Vegetative Propagation occur?
It can occur in the roots, stem and leaves
In which type of cells does binary fission most commonly take place in?
Prokaryotic
What is one kind of asexual spore?
Ex. conidiospores and Sporangiospores
What are three different organisms that can regenerate limbs?
Ex. humans, some lizards, starfish, salamander, crayfish.
Is Budding always asexual
Yes
Name two of the three types of Vegetative Propagation.
grafting, air-layering and the use of cuttings
What happens during the process of binary fission?
One parent cell splits into two brand new daughter cells carrying the identical genetic material that was in the parent cell.
Where do spores often grow in and around?
Tree stumps and around a trees base
In what cellular process does regeneration occur?
Mitosis
After a bud detaches from the parent cell what happens?
It will continue to grow until it is the same size as the original parent cell.
How long does the process of Vegetative Propagation take?
For new roots/stem to grow it takes about 14 days.
What are the four types of Binary Fission?
Irregular, transverse, longitudinal, and oblique.
True or False, spores can survive and grow in cold temperatures
False, warmer temperatures are more ideal for spore growth
Does regeneration work better with simple or complex organisms, why?
Regeneration works better in simple organisms or cells, this is because when there is more to copy in a cell the more likely it is to fail. That is why in simple organisms or cells it works better because there is less to copy and therefore less things to make mistakes on.
How many nuclei does the parent cell nucleus separate into when creating the new bud?
It separates into two nuclei for the new bud.
What is Artificial Vegetative Propagation?
Artificial Vegetative Propagation is: The intentional creation of new plants by humans using parts from existing or old plants.
What are the 4 steps to binary fission? (Basic explanation)
1. Replication of DNA
2. Growth of the cell
3. Segregation of DNA and cell elongates
4. Splitting of the cell into two new daughter cells
What are key differences between reproduction and regeneration?
Reproduction is more focussed on creating an offspring whether it be through asexual reproduction or sexual reproduction. However regeneration is a process in which an organism repairs it regrows a damaged or missing part.
