Briefly summarize the structure of moss.

Answers

Mosses are ​bryophytes​, primitive plants believed to be among the first to develop the ability to live on land. Moss plants have no vascular tubes to transfer water or nutrients, and no true stems or roots. Environmental water sources and absorption limit moss plant size.

There may be as many as 15,000 species of mosses. Although unique species of moss grow in dramatically different habitats across the planet – from the arctic to the desert – all have basically the same structure.

Basic Moss Spores

The initial moss plant is a spore given off by the sporophyte that forms at the end of the moss plant’s “stem.” Released spores travel long distances on the wind and may remain viable for decades. Moss spores landing in suitable conditions divide and produce hairy filaments called ​protonemas​, which are like thin plant threads that weave across the growing medium. Sprouting from the spore filaments, gametophytes form, held to the surface by rhizoids.

Main Structure of Moss

The main moss structure is the ​gametophyte​, which functions like a moss’s “stem” and “leaves.” A moss "stem" is called the ​axis​, and this part of the moss supports leaf-like structures.

​Phyllids​ are the leaf-like structures that carry out photosynthesis, transforming sunlight into sugars the moss uses for food. Typically arranged in a spiral, moss “leaves” are usually one cell thick with ribs two or more cells thick down their centers. The cells of moss plants contain ​chlorophyll​, the green pigment that is essential for the process of photosynthesis.

Does moss have roots? No, not really. Moss stems end in root-like strands called ​rhizoids​, specialized to hold the moss to its growing surface. Rhizoids anchor moss plants to the surfaces they grow on, but they do not absorb water and nutrients like true plant roots.

Second-Generation Growth

The second moss structure is really a second generation. Moss reproduction occurs sexually, using separate plants produced at different times. The two separate kinds of moss plants are called ​gametophytes​ (which produce gametes) and ​sporophytes​ (which produce spores).

Gametophytes are tipped with either inverted cone-shaped areas (​archegonia​) or male reproductive organs (​antheridia​). Released sperm (​antherizoids​) need water since they swim to the archegonium. This is one of the main differences between bryophytes and vascular land plants – mosses need water for their sexual reproduction process.

Fertilization occurs once an antherizoid swims to an archegonium. Sprouting from the gametophyte tip after fertilization, a sporophyte holds itself in place by anchoring a foot in the archegonium.

Spore-Bearing Parts

The sporophyte stalk, called the ​seta​, bears the ​sporangium​ (spore capsule) on its tip. One sporangium may produce up to one million spores. Maturing spore capsules are guarded by a covering called the ​calyptra​ that shrivels and falls off when the spores are mature. The calyptra can be a distinguishing part of a moss species, and they are often useful in identifying new mosses.

A cap called the ​operculum​ tops the capsule's opening under the calyptra. The capsule opening (​peristome​) can have teeth that help hold it closed. Matured spores are released when the capsule top ruptures and drift off to form new plants. Like the calyptra, the operculum and peristome of some moss species are highly identifiable.

Mosses are small, non-vascular taxonomic plants

Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?

a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.​

Answers

Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.

The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.

In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.

Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.

The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.

Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.

The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.

A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A. ​

Answers

C. Potential energy is stored energy, point D is taller so it has more stored energy

Potential energy is greatest at point D. Therefore, option C is correct.

What is potential energy?

Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.

The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.

Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Find the remainder when p(x) = –2x5 + x4 + 5x3 + 4x + 1 is divided by (x - 2).

Answers

The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.

To solve the question above, we make use of the remainder theorem.

Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).

From the question,

Given:

Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1Divisor ⇒ (x-2)

in view of the above and applying the Remainder theorem, The remainder will be p(2)

p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1p(2) = -64+16+40+8+1p(2) = 1

hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1
