    Introduction/Purpose There are many parts to a seed. First, there is the testa (seed coat). It is the outside layer protecting the inside of the seed. On the side of the seed, there is a tiny hole called the micropyle. Water can be taken through the hole when it is ready to germinate. Inside the seed near the micropyle, there is a root called a radicle. When the seed begins to grow the radicle will come out the micropyle. The seed coat can protect the seed from many factors such as freezing temperatures, heat, radiation, or acidity. Each seed has to go through the process of seed germination before they become a plant. With the right temperature and amount of water, the seed should start germinating within a couple days. The oxygen and water helps to break down the sugars, proteins, and other nutrients in the seed to obtain energy so the seed can sprout. The water also plays a major part in helping the seed sprout. When the dry seeds take up the water the process is called imbibition. While this process is happening, the enzymes are being activated which hydrates the seed and helps the plant grow. Then seeds begin to expand and break out of the seed coat. It is important to know the process of germination before you can begin the experiment, because you need to know what factors can affect how the plant grows. The radish seeds germinate fast only in about three to five days which is why we are going to use it The purpose of our experiment is to see…

    More than 65% of ovules were just enlarged without undergoing callus or shoot phase independent of the sucrose concentration. Rest of the ovules was either with no development or dead after 8 weeks of culture period. The effect of sucrose concentration on ovule response was not pronounced (Table 18). When comparing the suitability of sucrose concentrations (2% or 4%, 4% 0r 6%, 2% or 6%) for ovule culture depending on the genotype, there is no significant difference for both genotypes on whatever…

    Stigma connects to the ovary. Ovary is located below the flower. The ovary also has the ovule within it. The pedunkle is the lower most part of the follower. The pedunkle has the receptacle and the sepal. Right after the sepal is the petals. The petal is actually the flowers. The flowers attract pollinators by their colors like bees and hummingbirds. The flowers are a beautiful red that surround the ovary and the style. The leaf is a dark and has leaf veins form of a net pattern. The leaf is…

    Gymnosperms are the naked bearing seeds (e.g conifers, cyadas etc.) that thrived as the climate dried, differentiating them from bryophytes and non-vascular seedless plants. In the late Mesozoic era, around 140 million years ago, angiosperms began to replace gymnosperms in certain ecosystems. Angiosperms are seeds of flowering and fruit-bearing plants and have a intricate life cycle. Within the diploid megasporangium of each ovule the diploid megasporocyte will meiotically divide into four…

    Flowers, produce by the sporophyte, function in sexual reproduction The four floral organs are sepals, petals, stamens, and carpel. Sepals protect the floral bud. Petals help attract pollinators. Stamens bear anthers in which haploid microspores develop into pollen grains containing male gametophytes. Carpel contains ovules (immature seeds) in their swollen bases. Within the ovules, embryos sacs (female’s gametophytes) develop from megaspore. Pollination which precedes fertilization is the…

    very rare cases there have been monoecious plants found, but they are extremely rare. The male to female ratio in naturally occurring jojoba sites tends to be 1:1 with some variance in different locations. Pollination occurs by mode of wind, as the pollen is aerodynamic and very light, and it occurs from late January to early March in normal conditions. The male flowers are typically smaller than the female flowers, but both are a green-yellow mixture. (Niklas & Buchmann) The female flower…

    menstruation as “a periodic discharge of a sanguineous fluid from the uterus and Fallopian tubes occurring during the time of a woman’s sexual activity, from puberty to menopause.” He goes on to state that on average girls usually begin menstruating around the age of 15. However he believes that not all girls begin menstruating at fifteen because “(a) Race, (b) Mode of Life, (c) Climate, (d) Heredity, (e) Genital Sense” are all factors that can influence a girl’s body. He specifically states…

    water in the cell. The pancake-shaped chloroplasts have an important role, because that is where photosynthesis takes place -- a vital part of any plants life. Speaking of life, Chrysanthemums have been cultivated since the 15th century in Eastern Asia. The strange discovery of this particular species, Chrysanthemum belliam, growing in western Africa is a mystery -- a wonder of life, but it is clear it is being continuously selected and not just surviving, but thriving in this environment. They…

    Plants have four major periods of plant evolution that are marked terrestrial adaption. First is the origin of gametangia, which protects the embryo or sperm of plant. Second is the origin of vascular tissue it conduct water and nutrients. Third is the origin of seed where the embryo is protected from desiccation and other dangers. Fourth the origin of flower bear ovules within protective chambers called ovaries. Animals evolved from cells. One of the first cell was found 3.5 million years…

    has long been know as Brownian motion in his honor” (Britannica 2). Scientists extensively misunderstood Brown’s discovery of the Brownian motion. Scientists had asserted that Brown did not have the correct microscope needed to prove such a theory. “It has become plain that many workers have discussed the problem without consulting Brown’s original words on the subject, and it is abundantly clear that the optical propensities of the original microscope owned by Brown have been widely ignored”…
