write down the steps of double fertilization
Steps of Double Fertilization.
It was discovered by S.G. Nawaschin (1897) Lilium are Fertillaria sps.1. Germination of pollen on stigma :
(i) By absorbing secretion of stigma pollen swells up and outer layer exine ruptures whereas inner lintine comes out in the form of pollen tube.
(ii) Branched polen tube is formed in amentiferae group.
(iii) In families malvaceae, cucurbitaceae, etc. polysiphonous condition (many pollen tubes from a single pollen) is found.
2. Path taken up by pollen tube :
(i) Pollen tube pierces through stigmatic papilla into the tissue of style.
(ii) Filiform apparatus of synergids secrete some chemotropically active substances, which promotes porogamy.
(iii) Obturator (special structure) act as a bridge for growth of pollen tube.
(iv) Cations are naturally occurring chemotropic agents in the pistil.
3. Entry of pollen tube into embryo sac :
(i) It enters into the ovule by either of the two methods; porogamy, chalazogamy or mesogamy.
(ii) Irrespective of the mode of entry of pollen tube into the ovule, the pollen tube always enters into embryo sac at micropylar end (Porogany).
(iii) If enters through chalaza (base) it is termed chalazogany.
(iv) If pierces through integuments, it is called mesogamy.
(v) Tip of pollen tube penetrates embryo sac and reaches egg apparatus.
4. Syngamy (Generative fertilization)
(i) Pollen tube burst as tube nucleus disorganises.
(ii) One of male gametes fuses with egg cell or oosphere.
(iii) Deploid oospore or zygote is formed.
5. Triple fusion (Vegetative fertilization) :
The other gamete fuses with secondary nucleus forming triploid primary endosperm (PEN) which later give rise to endosperm.
Answer:
Double fertilization is a process unique to flowering plants (angiosperms) in which two sperm cells fertilize two different structures within the female reproductive system. The steps of double fertilization are:
Pollination: transfer of pollen grains from the male to the female flowerGermination: the pollen grain forms a pollen tube and grows down the style towards the ovuleSyngamy: the first sperm cell fuses with the egg cell to form a diploid zygote (2n)Endosperm formation: the second sperm cell fuses with two polar nuclei to form a triploid cell (3n) which undergoes cell division to form the endospermEmbryo formation: the zygote undergoes several rounds of cell division and differentiation to form the embryoDouble fertilization leads to the formation of both the embryo and endosperm within the ovule, which ultimately results in the development of a seed.

Explanation:
A cell goes through cellular respiration and produces ATP which it then uses to move a molecule across the cell membrane. How does the energy in the original glucose molecule change during this process?
-The stored energy in the glucose is used to produce ATP that can be converted to mechanical energy when the molecule moves across the cell membrane.
-The energy in the glucose is stored as kinetic energy in the ATP and released as potential energy when the molecule moves across the cell membrane.
The energy in the glucose is stored as mechanical energy in the ATP and released as potential energy when the molecule moves across the cell membrane.
The kinetic energy in the glucose is stored as potential energy in the ATP and released as kinetic energy when the molecule moves across the cell membrane.
During cellular respiration, a cell generates ATP, which is subsequently utilized to facilitate the movement of a molecule across the cell membrane. The stored energy in the glucose is used to produce ATP that can be converted to mechanical energy when the molecule moves across the cell membrane. Thus, the correct answer is Option 1.
During cellular respiration, a cell breaks down glucose into ATP, which acts as the energy currency in the cell. This ATP is then used to power cellular activities, including the active transport of molecules across the cell.
When glucose enters cellular respiration, its stored energy is slowly released and taken up as ATP. This energy conversion is mediated by a series of chemical reactions that occur during the stages of cellular respiration, such as glycolysis, the citric acid cycle, the electron transport chain and the breakdown of glucose and ultimately produce ATP molecules.
Once ATP is produced, it can be used by specific proteins called transporters or pumps built into the cell. These transporters harness the energy stored in ATP and use it to move molecules aggressively through the cell, against their increased concentration This movement requires an energy input and is essential for cellular internalization in various processes such as nutrient uptake, waste removal and signal transduction.
Therefore, the correct answer is Option 1.

brainly.com/question/32872970
The correct answer is Option a. The stored energy in the glucose is used to produce ATP that can be converted to mechanical energy when the molecule moves across the cell membrane.
During cellular respiration, glucose is broken down in a series of enzymatic reactions in the presence of oxygen. This process occurs in multiple stages: glycolysis, the Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle), and the electron transport chain.
In glycolysis, glucose is converted into pyruvate, generating a small amount of ATP and NADH. Pyruvate then enters the mitochondria, where it is further metabolized in the Krebs cycle, resulting in the production of more ATP and electron carriers (NADH and FADH2). These electron carriers donate their electrons to the electron transport chain, located in the inner mitochondrial membrane.
The electron transport chain uses the energy from the electrons to pump protons across the membrane, creating an electrochemical gradient. This gradient is used by ATP synthase to produce ATP from ADP and inorganic phosphate through a process called oxidative phosphorylation.
Once ATP is generated, it can be utilized by the cell to perform various energy-requiring processes, such as active transport of molecules across the cell membrane. In this case, ATP can be hydrolyzed by an ATP-powered pump, such as a sodium-potassium pump, providing the necessary energy to move molecules against their concentration gradient.
Therefore, the energy in the original glucose molecule is ultimately converted into ATP, which can be utilized as a source of energy for the cell. When ATP is hydrolyzed, the stored energy is released and can be converted into mechanical energy to drive processes like molecule transport across the cell membrane. Therefore the correct option is A

A cell membrane is very specific about what it allows across. How does t help the cell?
Answer:
Explanation:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

Temperature in degrees Fahrenheit can be converted to Celsius by first subtracting 32, then dividing by 1.8. What is the Celsius temperature outside on a warm day 100.
What is temperature?
Temperature is a unit used to describe hotness or coldness. It can be stated in terms of any number of arbitrary scales and shows the direction in which heat energy will naturally flow, i.e., from a hotter body to a colder body (one at a lower temperature).
Temperature is not the same as the energy of a thermodynamic system; for instance, an iceberg has a significantly larger total heat energy than a match, despite the fact that a match is burning at a much higher temperature.
As opposed to extensive characteristics, like mass or volume, temperature is referred to as an intense property—one that is independent of the quantity of matter being considered—along with pressure, density, and other comparable properties.
