What is periderm and protoderm and where do they originate from in a new plant ?

Biology
1 answer:
Sati [7]3 years ago

Periderm is the corky outer layer of a plant stem which the plant creates as a result of an injury or infection so as to protect itself further. Protoderm is the thin layer which covers embryos, as well as the root and stems, and later produces epidermis, which is the outer layer of tissue of plants (anywhere where periderm doesn't cover them).

Korvikt [17]

Answer:

Temporal partitioning or niche differentiation

Explanation:

Temporal partitioning refers to the variability in the competitive abilities of different species competing for the same resources based on varying conditions of the environment.

The environmental factors could be light, temperature, moisture, etc. Each species specializes in feeding within varied condition of one or more of the factors.

<em>In this case, both species are in competition but while the first species feeds during the day, the second species feeds during the night. Here, light and temperature probably plays a huge factor.</em>

Temporal partitioning is also known as niche differentiation, segregation, separation or niche partitioning.

What is the difference between natural selection and artificial selection?
sweet [91]

Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.

Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.

Some examples of natural selection include the selection of long-necked giraffes and the changes in the size and shape of beaks of birds according to their feeding habits.

Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.

A person is told to take 1.25 mg of vitamin d daily. how many 0.125-mg tablets should this person take?
vovikov84 [41]
This is a simple calculation involving drug doses.

The solution is as follows:

(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets

So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.

1.) Compare the roles of oxygen and carbon dioxide in autotrophs and heterotrophs. Which organism is an oxygen consumer and carb
wariber [46]

Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

I hope I helped!
