how does the Smooth Endoplasmic Reticulum function work in a plant cell
4-5 sentences
thank you
Answer:
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
Consider the cell cycle shown below. A cell will stop dividing and go into Go, the resting phase, if it
receives the proper signal at the G₁ checkpoint.

meiosis is a continous process but we can think of it as taking place in two stages meiosis i and meiosis ii. describe the products of each stage. how do the product
A reduction division and an equatorial division make up meiosis. To create gametes, meiosis I and meiosis II are necessary.
Meiosis II resembles a mitotic division, whereas meiosis I is a special cell division that only happens in germ cells. Meiosis, which decreases chromosome counts from diploid to haploid, and conjugation (fertilisation), which restores the diploid state by joining two haploid cells, are the two opposing processes that make up this. Chromosome segregation and recombination are the two processes that meiosis uses to create variety. As in mitosis, sister chromatids (the two halves of a duplicated chromosome) still need to be separated. The homologous chromosomes, which an organism acquires from both of its parents and are similar but not identical, must also be separated.

The locations for three genes have been added to this cartoon. For clarity, the locations have only been noted on one chromatid. The lowest frequency of crossovers would occur between genes ____ and ____.
The lowest frequency of crossovers would occur between genes a and b (the genes closet to one another on a chromosome)
The exchange of genetic material between the non-sister chromatids of two homologous chromosomes during sexual reproduction, or chromosomal crossover, leads to recombinant chromosomes. It is one of the last stages of genetic recombination, which takes place during the synapsis process at the pachytene stage of prophase I of meiosis. Before the synaptonemal complex forms, synapsis starts, and it doesn't stop until close to prophase I's conclusion.
The distance between genes is directly inversely correlated with the probability of gene crossing over between two genes that are located on the same chromosome (linked gene). Unlinked genes are assorted independently during cell division when two genes are not found on the same chromosome. Therefore, crossing over occurs frequently.

The hypothesis is not supported because the mass of the grape increased in grape juice.
What is mass?A physical body's mass is its total amount of matter. Inertia, or the body's resistance to acceleration (change of velocity) when a net force is applied, is also measured by this property. The gravitational pull an object has on other bodies is also influenced by its mass.
The kilogram is the fundamental mass unit in SI. Although mass is frequently determined by measuring an object's weight on a spring scale rather than a balance scale and directly comparing it with known masses, mass and weight are not the same things in physics. Although there is less gravity on the moon than there is on Earth, an object would still have the same mass.

During photosynthesis in a eukaryotic cell, an electrochemical gradient is formed across the ___________.
During photosynthesis in a eukaryotic cell, an electrochemical gradient is formed across the Thylakoid space.
What is Thylakoid space ?
The thylakoid space is the area inside the thylakoid. A thylakoid is a membrane-bound disc found in plant chloroplasts. The thylakoid membrane contains enzymes required for photosynthesis's light-dependent reactions. During photosynthesis, an electrochemical gradient or proton motive force is created by the release (photolysis) or movement of protons from the stroma into the thylakoid lumen. The energy released during this movement is used by ATP synthase, CF o, and CF1 particles to form ATP mole.
Inside chloroplasts and cyanobacteria, thylakoids are membrane-bound compartments. They are the site of photosynthesis's light-dependent reactions. Thylakoids are made up of a thylakoid membrane that surrounds a thylakoid lumen. Chloroplast thylakoids frequently form grana, which are stacks of discs. Grana are linked together by intergranal/stromal thylakoids, which connect granum stacks as a single functional compartment. Chlorophyll pigments are found in packets called quantasomes in thylakoid membranes. Each quantasome has between 230 and 250 chlorophyll molecules.
The thylakoid membrane is the site of photosynthesis's light-dependent reactions, with photosynthetic pigments embedded directly in the membrane. It is an alternating pattern of dark and light bands 1 nanometre in width. The thylakoid lipid bilayer is similar to prokaryotic membranes and the inner chloroplast membrane.

An ion that may flow across a membrane typically exhibits an electrochemical gradient, which is a gradient in electrochemical potential. The gradient is made up of two components: an electrical gradient and a chemical gradient, or a difference in charge across a membrane and solute concentration, respectively. What is the Thylakoid membrane?In chloroplasts and cyanobacteria, the light-dependent photosynthesis processes occur in thylakoids, which are membrane-bound structures that resemble sheets. Chlorophyll, which is present there and used to absorb light and utilize it for biological processes, is where it is found. Thylakoid is short for the pouch and has the -oid ending.Lamellae, another name for thylakoids, can also refer to the part of a thylakoid that joins grana.The water photolysis, electron transport chain, and ATP synthesis processes are all carried out in the thylakoid.The thylakoid membrane is the location of the light-dependent processes in photosynthesis because it contains photosynthetic pigments (such as chlorophyll). With a large surface area to volume ratio due to the stacked coil form of the grana, photosynthesis is made more efficient.To learn more about Thylakoid membrane, refer to:
