What is vegetative propagation?

Biology
1 answer:
guajiro [1.7K]3 years ago
7 0

Answer:

A type of asexual (only 1 organism needed in the process, only 1 parent) reproduction found in plants.

Explanation:

Vegetative propagation consists in the sharing of a stalk/root/other to form a new plant. So basically what happens is that a stalk/root/other from a parent plant is "left apart" so that a new organism can rise from it.

Some plants have parts that are used exclusively during vegetative propagation.

What’s vegetative reproduction (biology)<br><br> give description and example.
Virty [35]

Vegetative reproduction is a mode of asexual reproduction naturally occurring in plants. In this process. only one of the parent is involved and the offspring is genetically identical to the parent and no sharing of DNA takes place.

Examples are:  Onion, rhizome (ginger) and daffodil

Explanation:

There are meristem tissues found in the stem, root and leaves. These are undifferentiated cells and have tendency of dividing. This tissue gives rise to organs of the plant and responsible for its growth.

Natural vegetative propagation happens when an axillary bud grows into a lateral shoot and develops adventitious roots consequently forming a new plant.

Vegetative propagation can be done artificially also.

Which process can increase the rate of greenhouse gas emissions into the atmosphere in response to a decrease in albedo?
Vesnalui [34]

B. Ice-albedo feedback

Explanation:

The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo.

Albedo is the ratio of reflected light to incident light.

A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation.

Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice.

Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c

How does a low albedo relates to increase in greenhouse gas emission?

  • The ice-albedo feedback can substantially contribute to greenhouse gas emission.
  • The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions.
  • When ice melts, they leave land bare and exposed.
  • Melt water collects in pockets.
  • Exposed land leads to a decrease in albedo.
  • Organisms can thrive more in warm terrain.
  • Also, pockets of carbon dioxide gases trapped in ice is released.
  • Organisms release carbon dioxide into the atmosphere during cellular respiration.
  • Soils originally permafrost will become stable and this will encourage more human occupation of the area.
  • All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.

Regulatory and basal transcription factors regulate transcription by binding to the promoter.A) True B) False
Licemer1 [7]

Answer:

False

Explanation:

In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.

There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.  

Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
