What are the structures of plants and their functions?
There are various plant parts, each with its unique characteristics and functions to do. Each one of them plays a vital role in maintaining a healthy ecology and environment.
The parts of the plant include
Roots: The most crucial component of a plant is its roots. They are located underground and make up a plant's root system. They are responsible for holding the plant in place with the soil. They serve as an anchor that the plant uses to keep itself steady. By soaking up water, nutrients, and minerals from the soil, they also control the health of the plant. A plant can grow as a result of these. Additionally, they keep food supplies for later use.Stems: It is the second most crucial component. It rises above the ground, starts out green, and eventually turns brown as it gets older. They consist of leaves, fruits, and flowers and sustain the plant's stalk system. They support the framework and structure of the plantLeaves: Chlorophyll, which is responsible for the synthesis of plant food, can be found there. To prepare the food, it makes use of water, carbon dioxide, and sunlight. A leaf is further divided into three main parts: the petiole, leaf base, and lamina.Flowers: There are certain plants that do not have flowers. They have a vibrant, peaceful aesthetic. They are the plant's reproductive system. Petals, sepals, stamens, and pistils are its four main constituent components.Fruits: Fruit production is carried out by flowering plants. After fertilization, the fully developed ovary transforms into a fruit. They develop into a seed first, then a fruit.Learn more about plants here:

21. A soft sedimentary rock, like limestone, can change over time into a hard metamorphic rock
like marble. What processes must have acted on the limestone over the years to change this
sedimentary material into hard metamorphic material?
Answers
Answer:
The heat generated by the magma chamber has changed these sedimentary rocks into the metamorphic rocks marble, quartzite, an hornfels. Regional Metamorphism occurs over a much larger area. This metamorphism produces rocks such as gneiss and schist. ... They are generally as hard and sometimes harder than igneous rocks.
If sedimentary rock, pressed inside the crust and treated with a high pressure and temperature, then it can change over time into a hard metamorphic rock.
What is a sedimentary rock?A sedimentary rock is mad up by the decomposition of minerals and other organic matter near the water surface.
These rocks are soft, such as limestone.
These rocks can turn into hard metamorphic rocks if they came in contact with high pressure and temperature.
Thus, by high pressure and temperature, the sedimentary rock change into hard metamorphic rock.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
Answers
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

Which of the following is not a function of the bacterial cell wall?
A. Provide the cell with shape and rigidity
B. Prevent the cell from lysing
C. Protect the cell
D. Provide the cell with locomotion
Answers
Answer:
D
Explanation:
I believe locomotion would be the job of the flagellum
The correct option that is not a function of the bacterial cell wall is : ( D ) Provide the cell with locomotion
The Bacterial cell wall acts mainly as a protective cover to the cell of the bacterium, protecting the cell from lysing ( preventing the breakdown of the cell via osmotic pressure ). The cell wall also provides the cell with shape a and rigidity.
While The locomotion of the cell is not the responsibility of the cell wall but it is made possible by the flagellum.
Hence the non - function of a bacterial cell wall is providing the cell with locomotion.
