Seed William Dimichele Analysis

In a plant’s life cycle, there are a few key details such as germination, growth, egg or sperm production, pollination, seed production and dispersal, and finally death. In the germination phase the seed sprouts after a certain exposure to light, temperature, and moisture (Pima Community College). In the growth stage the sprout turns into a mature plant, this is followed by the production of an egg or sperm and then pollinated by other pollen transferred by the wind or an animal. Next is the seed production when the embryo and endosperm get a seed coat to form a new seed, the dispersal of the seed occurs it is transferred from the parent by interaction with an animal. Finally death, it’s pretty obvious, death is when the plant dies.

Happy Tuesday! Seedlings 2 began their day outside on the playground. We explored so many environmental objects and we moved in response to music and rhythm as we played with musical instruments with Ms. Clara. When we returned to our classroom, we explored floating green objects in our Sensory tub. Later we exercised our gross motor skills as we practice walking with our walker. I do hope you enjoy another fabulous day with Seedlings

Germination of a seed is the process Germination is the process when a plant grows from a seed. The seed stores the embryo until the conditions for germination are met. When the seed is placed in sustainable environmental conditions its embryo will grow and burst through its coating. The seed coat protects the seed before germination begins. This is important when the seed is in dormancy- the state of the seed being prevented from starting the germination process due to environmental conditions that may affect the chances of the seed growing. Germination takes

In fact, there are at least 250,000 known species of angiosperms leaving them the most diverse plant group (Evolution). Angiosperms have three features that set them apart from gymnosperms: flowers, double fertilization, and embryos with an ovarian wall (Evolution). Angiosperms’ flowers are what carries the male and female reproductive systems (Evolution). Double fertilization is when “two male gametes (sperm nuclei) are released from the pollen tube into the ovule. One of these sperm nuclei fuses with an egg cell in a similar way to gymnosperms. The second nucleus (which degenerates in most gymnosperms) fertilizes other cells in the ovule called polar nuclei. Most commonly, two polar nuclei fuse with the sperm nucleus to form a triploid endosperm nucleus. The tissue that forms from this fusion is called endosperm, which in most angiosperms provides nutrients for the developing embryo” (Evolution). Finally, after embryo fertilization has occurred, the ovarian wall that protects the embryo will become fruit

Each picture indicates how the germination progress of Zinnia’s seeds flows through my entire experiment. In step one, the Zinnia seeds were placed on paper towels that were numbered one through four. In step two, enough water was applied on the paper towel to cover all seeds and to make sure that the paper towel was moist. In step three, the moist paper towel was placed in the correct label plastic zip top sandwich bags. In step four, I observed the growth of the germinated seeds and placed them into the plastic planting pots that was numbered one through four. In the last step, step five, all the germinated seeds had sprouted and planting pot number four sprouted the most.

When people tell you that you can't do something, that doesn't mean they're right. If you want to do something, do it. Don't let someone tell you what you can or can't do. In Teresa Sendra Aganosts short story "The Seed" from Chicken Soup for the Kids Soul 2 a girl named Teresa wants to grow an orange tree, but, she lives in New York. Everyone says she can't but that doesn't mean she won't try. This short story teaches readers that you can do anything if you belive in yourself.

One effect of taking Black Seed is a process of detoxification (detox), namely the process of spending toxins or substances that are toxic from the body. Cleansing and detox enhance the natural process of spending toxins from our body.

After the process of pollination and the development of the embryo stops, a seed is formed. The seed will remain dormant until it comes in contact with water which causes gibberellins (a type of plant hormone) to be released which will trigger the layer covering the embryo to produce enzymes needed to break down the endosperm and release the nutrients that are stored there. Those nutrients will be used by the embryo for growth. Hormones are chemical substances that help and regulate plant growth and aid in seed germination (Gutzler and Brewer 2013). There are seven different types of plant hormones and they all trigger specific reactions.

Some plants secrete chemicals that inhibit the germination & growth of nearby individuals that could compete for resources

The reproduction system for plants consists of the anther, stigma and ovule. The image by Hans Lambers (2016) shows that pollen is created through the stamen (anther (which is held up by a filament). The pollen is then moved through wind, water or animal to the stigma of the plant “part of the pistil where the pollen germinates” (The Parts of a Flower, n.d.). Which is then moved down the pollen tube (inside the style) where it reaches the ovary and fertilizes the ovule and reproduce.

In order for a seed to germinate, many conditions must be met. Firstly a seed must be viable. If a seed is viable it require a suitable environment with proper levels of moisture, suitable temperatures, oxygen, fertile soil, and proper pH levels to name a few. However, as many of us have experienced, some viable (living) seeds will NOT germinate, even when given the perfect conditions. In the field of botany, this phenomenon is known as “physiological seed dormancy” (will be referred to as PSD from here on out). In plain language, PSD is like a “hibernation” stage that occurs after seed maturation but before germination.

Of course seeds consist of several components, but the three main and most significant parts are the seed coat, the endosperm and the embryo.

Vegetative propagation is a process in which new plants are obtained without the production of seeds or spores. It involves the propagation of plants through certain vegetative parts such as the rhizome, sucker, tuber, bulb, etc. It does not involve the fusion of the male and the female gamete and requires only one parent. Hence, vegetative reproduction is considered as a type of asexual reproduction.

The seed biology is known to be the most important stream of plant science. Various experiments for seed germination are carried out under controlled environment. Researchers have experienced a need to maintain and monitor the relative humidity,
