How plants reproduce

Reproduction in flowering plants begins with pollination, the transfer of pollen from anther to stigma on the same flower or to the stigma of another flower on the same plant (self-pollination), or from anther on one plant to the stigma of another plant (cross-pollination). Once the pollen grain lodges on the stigma, a pollen tube grows from the pollen grain to an ovule. Two sperm nuclei then pass through the pollen tube. One of them unites with the egg nucleus and produces a zygote. The other sperm nucleus unites with two polar nuclei to produce an endosperm nucleus. The fertilized ovule develops into a seed.

This is the flower we chose to get for our dissection its is from the broccoli plant outside.

 this is aidan looking at the plant before our dissection.

Here you can see the stigma the male reproductive system and if you look close enough you can see pollen.

This is the female part of the plant that houses the gametes and takes pollen.

This is the ovaries and the green blob next to is the the gamete of the female reproductive system.

How our plant reproduces

This blog will tell you how Brassica plants reproduce. This is a picture of one of our broccoli plants flowers. This flower contains both the female and male genitalia. 

This is a close up of the male reproductive anatomy, otherwise called the stamen. The top of it is the anther which carries the sperm or gamete cells. Holding up the anther is the stalk. 

This is the female reproductive system called the carpel which has the stigma which is sticky so it can catch pollen. 

This is the ovary which contains all the ovules for the plant to make an embryo. the stigma catches the pollen and brings it to the ovary to make a seed.

How Does Your Garden Grow?-Aidan Deremer

Our plant has been growing by using a continuous cycle of processes to add biomass. The first step in the cycle is photosynthesis, which during this process gain glucose and energy that will ten be used in cellular respiration. During this process our plant creates ATP and nadph to give energy for the plant to survive and under go mitosis. Mitosis uses this energy to translate and transcribe information onto new DNA strands called RNA. through this the plant can create new cells for new organs and parts.
The plant would undergo translation and transcription to create new mRNA which are then created into codons which are turned into the enzymes needed to go through photosythesis.

How does your garden grow- Anthony

1. Our pant is growing and adding biomass by taking in the sun's energy and converting it into sugars and other nutrients the plants needs, hence photosynthesis. But after it completes the first part of photosynthesis it goes into cellular respiration which converts biochemical energy from nutrients to ATP then realising waste products.

2. The enzymes PEPC and Rubisco are made by having the DNA compiled and sending that part to the ribosmome with the messenger RNA. Then the translation begins creating RNA and the enzyme used to covert the three pairs of RNA condons to amino acids creating the combination to create the proteins needed to create these enzymes.

Student Blog Post Assignment #5: Seed Stories, Semester 1 Isaiah Pelascinca

Isaiah. He learned a lot more about plants in general. He also learned techniques for planting them. How fast his plants grew amazed him the most. Nothing made Isaiah laugh during his time working on Story of the Seed. Whenever he thought about the tiny cell within the plants that make the whole entire body work. A question he frequently asked himself during tstots is where the seeds themselves derive from.

For this blog I'm interviewing Beatrice, and she learned how plants grow. The cells of a plant are completely different from an animals cell. What made her think a little deeper was how much plants needed care. Her teammates were very helpful and cooperative, she had a very interesting experience in the project overall and enjoyed the fact that she help grow a plant

An Ecological Analysis of the Garden and Your Plants. Aidan Decremer

Some abiotic factors that our plant depends on are is the sunlight, the soil its planted in and the water it gets. The sunlight gives the plant the energy to photosynthesize. The soil gives the plant support for its roots, and it gives the plant nutrients. Then the water helps the plant survives. Some biotic factors that effect the plant is human activity and insects. Humans can accidentally step on plants causing the plant to die. And insects can eat plants.
Our plant is in competition with the plants around it for sunlight.
The plant that is bigger usually wins the competition for sunlight. It is sometimes hard to have a clear cut winner, but eventually you will see which plant better adapted to the conditions it was put in. Its hard to determine the winner because it takes a little while for plants to die and they can always somehow recover.
Our plant is also involved in a food chain. In this case our plant is a trophic level 1 being a producer for bugs and other small animals.
I think that secondary succession is occurring in the garden because there was soil in the boxes before we planted the saplings.
