Plants are the life forms from the Kingdom Plantae. They reproduce sexually and asexually, they can reproduce with only one parent. The plant lifecycle begins with a seed. It can grow with the right amount of sunlight, water, and the air. Next, the seed sprouts and the seed grows its roots, stem, leaves, flowers and more seeds. The leaves that are formed from the seeds stem are called seedlings. As the seed slowly becomes a plant it sheds seeds and the cycle continues.
The animals are the largest of the multicellular eukaryotic that is in the kingdom Animalia. They reproduce sexually. They need both male and female to reproduce.
Examples:
Mammals:
Female produce egg cells, which fertilizes with the sperm cells of a male. Based on the species
11.2) Asexual reproduction involves a single individual / parent who pass duplicates of all its genes to its offspring without the fusion of gametes. Sexual reproduction involves two parents who give rise to offspring that have unique combination of genes inherited from the two parents.
The article was mainly about how an egg reproduces with a sperm to create new individuals. The article also discussed how at one time the sperm and egg were the same. Over time, the sperm and egg have evolved to be different. The article mentions the challenges with the sperm being able to reach the egg. There is also a discussion about how the protein affects the reproduction and a discussion on reproductive failure.
There are five kingdoms of organization classifications, but the two most known are Kingdom Animalia and Kingdom Plantae. These two kingdoms have similarities and differences in cell biology and nutrient absorption.
This means that all the sperm in males and eggs in females are produced from meiosis. Sperm and egg cells are haploid cells-they contain only one of each type of chromosome. Meiosis actually starts with a diploid cell that undergoes two divisions; the end products are four gametes, all genetically different. Meiosis is known as a reduction division because the daughter cells always contain half the amount of chromosomes as the diploid beginner cell. Chromosomes come in pairs and these pairs are called homologous pairs. Homologous chromosomes mean that both of the chromosomes in the pair have the same gene sequence. Human somatic cells(diploid) contain 46 chromosomes consisting of 23 homologous pairs; therefore, human gametes, which are haploid, have 23 total chromosomes-one from each homologous pair. Just like in mitosis, meiosis undergoes all of the same phases. However, because meiosis involves two divisions, the cell goes through all the phases twice. When referring to the first time the cell undergoes a phase, we say 1, and when referring to the second time, we say 2. For example, when a cell starts prophase the first time in meiosis, we say it is going through prophase 1(P1). Also, there are some differences in the process itself. During P1, homologous chromosomes exchange a section of themselves in what is known as crossing over. This provides a source of genetic variation since part of each chromosome switched places with each other, thus making both chromosomes distinct from the original. Another important difference to know is that in anaphase 1, the doubled chromosomes are not separated into sister chromatids. This doesn’t happen until A2 to ensure that each of the four gametes receives one of each kind of chromosome. There are many key points to understand about meiosis. The first being that cells in meiosis do not go through interphase twice. Interphase is a “one-time” thing; DNA
An animal is a living thing which varies from a range of different sizes, shapes, forms and cells which are specialized to carry out certain functions (Quinn, 2003). There are certain functions mutual to all living things which are movement, respiration, sensitivity, growth, reproduction, excretion and nutrition (MRS GREN). These living processes are essential characteristics which are used to define species as living organisms (Worcester, 2015). Carl Linnaeus developed a system where animals were amongst one of the broad group in kingdoms, which he then divided into classes and were further identified by a Genus or a species name and this was known as the Linnaean classification system. A genus includes species of individual organisms grouped
Arthropods account for 80 percent of all animal species. Because arthropods have so many amazing features, they are very important animals. They have an exoskeleton, and an open circulatory system. Every time you look at an arthropod you will see a segmented body. Arthropods are astounding creatures! Without them our food chain would be all over the place!
Gender is determined by the sex chromosomes, XX produces a female, and XY produces a male. Males are produced by the action of the SRY gene on the Y chromosome, which contains the code necessary to cause the indifferent gonads to develop as testes (1). In turn the testes secrete two kinds of hormones, the anti-Mullerian hormone and testosterone, which instruct the body to develop in a masculine fashion (1). The presence of androgens during the development of the embryo results in a male while their absence results by default in a female. Hence the dictum "Nature's impulse is to create a female" (1). The genetic sex (whether the individual is XX or XY) determines the gonadal sex (whether there are ovaries or testis), which through hormonal secretions determines the phenotypic sex. Sexual differentiation is not drive...
UXL Encyclopedia of Science (2002), stated that seeds are a part of plant. It can be the cause for a new plant. When plants grow they will produce another set of seeds until the plants spread through the given space to them.
A fertilized egg cell, zygote, is produced when two gamete cells, male and female gamete, fuse by sexual reproduction. After sexual reproduction, a single sperm cell can live between 48-72 hours. The sperm cells begin to swim towards the fallopian tubes to fertilize the egg cell waiting in the fallopian tube. Fertilization takes around 24hours; once the sperm cell penetrates the oocyte it leaves the plasma behind and the egg cell changes its surface so that another sperm cell cannot penetrate the egg cell. After the sperm cell entering the egg it finishes it second meiotic division, which forms an ovum and a second polar body. Within 24-48 hours after fertilization early signs of pregnancy can be detected. (Chronolab)

David Michod explores the uses of intertextuality in Animal Kingdom through the use of a wide range of stylistic devices. He uses intertextuality to explore the physical “world” that exist below what is moral and correct based on the moral of the those living in the underworld, he also uses intertextuality to examine the behaviours of those who live within his perceived underworld through the uses of violence and drugs, and he uses intertextuality to question whether fate is set for those who are part of this society which operates just below what we know as moral and correct by having the authorities stopping anything that is not legal in our moral “world”.
...per’s glands mix with sperm to form semen. Each testis made up of small, coiled tubes called the somniferous tubules. From there, the immature sperm pass through the epididymis, which is a storage area on the upper rear part of each testis. The vas deferens is a tube that leads upward from each testis into the lower part of the abdomen. The two vas deferens empty into the urethra. The female reproductive system is somewhat like that of the frogs. In the female reproductive system the ovaries produce the female sex hormones estrogen and progesterone. In the ovaries eggs mature in the follicles. Fertilization may occur when the follicle breaks and the egg is released into the oviduct.
The giant pacific octopus is in the kingdom Animalia because it is multicellular, eukaryotic, and has no cell walls. In addition to this, the giant pacific octopus reproduces sexually and has cells that are used for specific functions. (Kalupa, 2012)
When looking at the biological make up of male and females, there are both similar physical characteristics
You may ask what is a Pangolin? Well a Pangolin has been an endangered species that lives in Africa. I think that the Pangolin is just an amazing animal. My animal is a endangered species that are trying to be relocated into captivity and saved. The Pangolin is an amazing animal that doesn’t need to become extinct so that’s why I did a research paper on it.
