Due to the information that they are short-day plants, I would expect chrysanthemums to flower during the times of the year when <u>days are shorter and nights are longer. </u>
Plants require sunlight to grow and flower or produce fruit. While some plants require more light than others, almost all plants require some form of light to survive, much less flower. Pants are often classified according to the amount of light that they require, these classifications are:
- Day-neutral plants
- Long-day plants
- Short-day plants
Day-neutral plants are those that can flower regardless of the amount of light that they receive. These are very resistant species of plants that can thrive even through periods of prolonged darkness. Though they do well with even a small amount of light, they will still require it to survive. One example of this kind of plant is the <em>tomato</em>.
Long-day plants are, as the name may suggest, plants who thrive when the days are longer. These plants will not survive or bloom without many hours of sunlight every day. The <u>optimal conditions for this kind of plant are meet during the summer,</u> when the Earth is tilted towards the sun, causing longer days.
Finally, short-day plants are those who require little sunlight to flower. These are different from day-neutral plants in that during days with many hours of sunlight, they will not flower. These plants, such as the chrysanthemums, will only flower if daylight hours are low, meaning that <em>spring</em> and <em>fall</em> are <u>optimal conditions for these plants to prosper. </u>

Answer:
The membrane is made from polar phospholipids allowing water to move freely in and out of the cell
Explanation:
The cell membrane is the organelle of the cell that allows for substances to be transported into and out of the cell. It is able to do this due to its semi-permeability. The membrane contains a phospholipid component, which contains a polar region that allows for polar substances such as WATER to enter and leave the cell.
The polarity of the phospholipid component of the cell membrane explains why water is insoluble in the middle of the semipermeable membrane.
During transcription process in the nucleus, the information for synthesis of a particular protein is copied on to mRNA.
mRNA then leaves the nucleus with this information in code, and enters the cytoplasm and attaches to a ribosome. Ribosome are the "work benches" of the cell and it is here that proteins are made.
In the ribosome, transfer RNA or tRNA recognizes a triplet of bases e.g. GCA on the attached mRNA and decodes it. This is called the translation process. Once tRNA has determined which amino acid corresponds to that triplet, it fetches that amino acid from the pool of free amino acids in the cytoplasm and into the ribosome where it is linked with other amino acids into a chain to form the protein.
Monocotyledons:<span>Embryos have a single seed leaf, referred to as a cotyledon - hence the name mono (one) cotyledonLeaves have parallel venation and are generally strap-like in appearanceFlowers have petals and floral parts in multiples of threeIn the stem, vascular bundles are scattered and absence of vascular cambium explains absence of secondary growthA pollen grain with one openingRoot system is generally fibrous, shallow and adventitiousStomata can be found on both epidermal layers of monocot leaves. This condition is called amphistomaticExamples of monocot plants are: (grasses) most ornamental turf lawns, (bamboo's) ornamental and wild bamboo's inlcuding sugar cane, (grain plants) rye, rice, wheat, maize (bulbous plants) such as lilies, agapanthus, clivia, orchid varieties, most palm tree varieties</span>
<span>It should be noted that Monocotyledonous plants make up one huge slice of the worlds cereal/ edible crops, the staple diet of literally Billions of people and animals! </span>
Dicotyledons:<span>Embryos have two seed leaves, referred to as cotyledons - hence the name di (two) cotyledon - although dicots now known as eudicots, most people still use the term "dicot"Leaves have branched venationFlowers have petals and floral parts in multiples of four or fiveIn the stem, the vascular tissue is arranged circularly and presence of vascular cambium explains ability to effect secondary growthA pollen grain with three openingsRoot system is generally branched, but taproot basedStomata can only be found in the lower epidermis. So, we describe it as hypostomatic conditionExamples of dicot plants include: (veg) tomatos, peppers, cabbage, beans, peas, (flowers) sunflowers, roses, daisies, violets, petunia, pansy (fruit) apples, pears, cherries, avocardo</span>
