Answer:

Figure 3 : Plant plasma membrane and cell-wall structure
A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary cell wall, the middle lamella, and the secondary cell wall (not pictured). The cell wall surrounds the plasma membrane and provides the cell tensile strength and protection.

Figure Detail
Besides the presence of chloroplasts, another major difference between plant and animal cells is the presence of a cell wall. The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall. Plant cells have high concentrations of molecules dissolved in their cytoplasm, which causes water to come into the cell under normal conditions and makes the cell's central vacuole swell and press against the cell wall. With a healthy supply of water, turgor pressure keeps a plant from wilting. In drought, a plant may wilt, but its cell walls help maintain the structural integrity of its stems, leaves, and other structures, despite a shrinking, less turgid vacuole.
Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth. Cellulose fibers are long, linear polymers of hundreds of glucose molecules. These fibers aggregate into bundles of about 40, which are called microfibrils. Microfibrils are embedded in a hydrated network of other polysaccharides. The cell wall is assembled in place. Precursor components are synthesized inside the cell and then assembled by enzymes associated with the cell membrane (Figure 3).
What Are Vacuoles?
Plant cells additionally possess large, fluid-filled vesicles called vacuoles within their cytoplasm. Vacuoles typically compose about 30 percent of a cell's volume, but they can fill as much as 90 percent of the intracellular space. Plant cells use vacuoles to adjust their size and turgor pressure. Vacuoles usually account for changes in cell size when the cytoplasmic volume stays constant.
Some vacuoles have specialized functions, and plant cells can have more than one type of vacuole. Vacuoles are related to lysosomes and share some functions with these structures; for instance, both contain degradative enzymes for breaking down macromolecules. Vacuoles can also serve as storage compartments for nutrients and metabolites. For instance, proteins are stored in the vacuoles of seeds, and rubber and opium are metabolites that are stored in plant vacuoles.
Conclusion
Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help reg

The enzyme ______ uses ATP to unwind the DNA template.
helicase
Prior to the replication fork, helicases are enzymes that catalyse the unwinding of parental DNA while also hydrolyzing ATP.
In lysates of E. coli, Arthur Kornberg discovered DNA polymerase for the first time in 1956. This enzyme's isolation was a seminal achievement in molecular biology since it offered a biochemical foundation for the manner of DNA replication that was first hypothesised by Watson and Crick. Ironically, however, E. coli DNA replication is not primarily carried out by DNA polymerase I, the first DNA polymerase to be discovered. Instead, it is now known that various DNA polymerases perform specific roles in DNA replication and repair in both prokaryotic and eukaryotic organisms.

What are the 2 main processes that occur during meiosis?
Meiosis generates diversity through two events: recombination and chromosome segregation.
Recombination is the process by which pieces of DNA are broken down and recombined to create new combinations of alleles. This recombination process creates genetic diversity at the gene level that reflects DNA sequence differences between organisms.
One of the most important processes in cell division is chromosome segregation, the division of genetic material into her two daughter cells. The mitotic spindle, a microtubule-based self-organizing intracellular structure found in all eukaryotes, is involved in chromosome segregation. Haploid gametogenesis requires precise chromosome segregation during meiosis. Improper chromosome segregation results in the formation of unbalanced gametes and aneuploid or polyploid offspring.

The three main parts of a carpel are the stigma, style, and ovary.
Explanation:
A plant can have green (G) or yellow (g) leaves. It can also have a long (K) or
short (k) stem. A scientist is preparing a Punnett square for a dihybrid cross
of a plant with a genotype GGKk. What possible gametes can the plant
produce?
O A. GK, Gk
• B. GK, gk
• C. GK, Gk, gk, gK
• D. GG, Kk
Answer:
The correct answer would be gk and gK.
Gamete refers to the haploid germ cell (male or female) which is able to fuse with another gamete of opposite sex of the same species in order to produce zygote.
According to the law of segregation only one copy of the gene (allele) is distributed to each gamete. In addition, it is a random process.
For example, gene Aa would result in the formation of two types of gametes. One will carry A and the other will carry a.
Now, according to the law of independent assortment, alleles of two or more genes are into the gametes independent of each other.
For example, in AABB alleles of gene AA and alleles of BB will be inherited independent of each other.
Now, gametes produced from gg will of only one type that is, g.
Gametes produced by Kk will be of two types which are K and k.
Lastly, all the alleles will be inherited independent of each other which forms two types of gametes. One bearing gK and one bearing gk.
Answer:
The correct answer is C. GK, Gk, gk, and gK.
Explanation:
During meiosis, the plant will produce gametes that contain one of the two alleles for each trait. The plant has two different alleles for the leaf color trait (G and g) and two different alleles for the stem length trait (K and k). Therefore, the plant can produce four different types of gametes: GK, Gk, gK, and gk. Each gamete will contain one allele for the leaf color trait and one allele for the stem length trait.

During which meiotic phase do cells become haploid?
Answer:
During meiosis, the process by which cells divide to form reproductive cells, cells become haploid in the second meiotic phase, also known as meiosis II. This phase follows the first meiotic phase, or meiosis I, during which the chromosomes in the cell are divided into two sets of homologous chromosomes. Meiosis II then involves the further division of these homologous chromosomes, resulting in the formation of four haploid cells, each with a unique combination of chromosomes.
During meiosis II, the cells undergo two rounds of cell division, known as anaphase I and anaphase II. In anaphase I, the homologous chromosomes that were separated during meiosis I are further divided, with one member of each pair moving to opposite poles of the cell. In anaphase II, the sister chromatids that were formed during meiosis I are separated, resulting in the formation of four haploid cells.
The formation of haploid cells during meiosis is important because it allows for the formation of genetically diverse offspring. By combining different combinations of chromosomes from each parent, the haploid cells produced during meiosis II provide the basis for the unique genetic makeup of each individual
Telophase II meiotic phase cells become haploid, DNA copied during the S phase just before meiosis.
What is the meiotic phase?The parent cell contains 92 chromosomes following the S phase since human cells typically have 46 chromosomes. The sister chromatids split during meiosis II, creating haploid cells with non-duplicate chromosomes.
Even though these cells are haploid and only have one chromosome from each homologous pair, they nonetheless have two sister chromatids.
Cells in the male or female sex organs go through one round of DNA replication before meiosis starts. Meiosis I and meiosis II, the two meiotic divisions, each have a number of stages. Meiosis I is a special kind of cell division that only occurs in germ cells, whereas meiosis II resembles mitosis.
