A List of Definitions of Plant Parts

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.

They also develop hairy leaves but for different reasons. In the Alpine Ecosystem they are doing it to help them keep the warmth they gained during the day and also to break the wind and provide a fairly warmer temperature around the plant. However in the Desert Ecosystem they do it to reduce water loss.

I learned that each individual section of the plant/flower structure has its own use. The petals of a flower are used to attract insects or smaller animals while the anther produces pollen. The pollen that is produced by the anther is carried by insects or animals to the pistil of another flower where it may fertilize the eggs.

Despite its importance osmosis may also damage cells by causing them to; a) shrink from water loss or b) burst from too much water gain. Plant cells [fig 3] have adapted themselves to ensure that these factors do not affect them, by forming a ridged wall, known as the cell wall, around their cells. The cell wall maintains the shape of the cell, and prevents the cell from bursting in a hypotonic medium by resisting water pressure. Plant cells have also adapted a larger vacuole, which occupies 80% or more of the cells cytoplasm (Davidson, 2004); allowing plants to store more water and nutrients per cell. Vacuoles also play a structural role in plant cells; by swelling when liquids contact them, plant vacuoles are able to control turgor pressure within the cell. This helps maintain the structural integrity of the cell as well as providing the plant with suitable amounts of water and nutrients; however the cell will never burst because the vacuole is contained within the cell wall. If plant cells are deprived of water their vacuole will begin to shrink, yet due to the cell the wall, the plant cell will be able to maintain its shape. [fig.4] Animal cells [fig 5] on the other hand do not have this

4. Why is there a sticky juice? The sticky juice holds the pollen in place for fertilization to occur.

According to The Editors of Encyclopædia Britannica, flowers, regardless of their diversity, all have a sole function; to reproduce (2017). There are two main organs that are involved in reproduction: the stamens and pistils. The stamen has spore cases (microsporangia) in which numerous microspores (potential pollen grains) can be developed. Fertilization can only occur through pollination; when the pollen grains from the anther is transferred to the stigma of a pistil. The two main types of pollination are self pollination and cross pollination. Self pollination also referred to as autogamy, is when a flower can fertilize itself because it has both female and male reproductive system. The most common type of pollination, however, is cross pollination. In cross pollination, a flower is

And to enable the other plants to thrive, that is populated and visited by birds, goldfinches, field sparrows, crows, a pair of king birds, buzzing hummingbirds and more. And some butterflies, monarchs, admirals, yellow and black swallowtails, checkered butterflies, sulfur butterflies, and a number of different kinds of moths,

Why we need the bees; The bees pollinate most the plants to produce fruits, seeds, and nuts. Like other bees, rusty patched bumblebees important crops for us to eat, such as tomatoes, cranberries and peppers.

Sexual Reproduction is the formation of a new organism from two parents usually, and involves the joining of gametes [ e.g. sperm, pollen, egg] to form a single cell called a zygote [ or fertilised egg ]. The offspring are similar, but not identical to the parents. Sexually Reproductive organisms include mammals, most reptiles, and flowering plants. ADVANTAGES

The generation rate and success of new asexual lineages will be influenced by the proximate mechanisms underlying transitions to asexuality. This article also explains how the asexual reproduction in animal and plants can be both a confused mix of term. It is known that in plants, asexual reproduction can occur either through budding and vegetative growth like for example the shoot and the runners. This article explain how the different terms people used in plants and animals refer to the same concept. An example is that in plants and animals, production of offspring via syngamy of meiotic produced gametes. These term are known in both plants and animals as sexual

<br>Water can also be used for support. As plant cells have cell walls as well as cell membranes, when the plant cell becomes full of water (due to osmosis) it will not burst but the cell wall exerts a force equal to the osmotic force (the cell is turgid) and this is important in the support of leaves and also in the stems of herbaceous plants. In animals like the earthworm support is often provided by the pressure of the fluid inside them,

Gymnosperms life and reproduction cycle go hand in hand . They reproduce sexually (Wilkin, Brainard). The gametophyte age happens in the cone. Every male gametophyte is only a couple of cells inside a grain of pollen. Every female gametophyte creates an egg inside the ovule, which eventually turns into a seed coat after fertilization. In gymnosperms, the cone is the female reproductive site and pollen is the male. Pollination has to occur in order for fertilization to happen. After pollination occurs, one sperm unites with the egg, which then forms a zygote. The zygote then transforms into an embryo inside the seed, in which the next generation of sporophytes develop (Plant Reproductive Development and Structure). It takes roughly about two years for a gymnosperm to complete its life cycle.

There are many types of asexual reproduction they are budding, fission, fragmentation, spore formation, parthenogenesis and vegetative reproduction. Budding is the outgrowth on a parent that grows into the offspring. Fission is when a parent divides into two making two individual organisms. Fragmentation is when an organism breaks into smaller parts and those parts regenerate a whole new body, spore formation is an offspring that is a protective coating, parthenogenesis is the development of eggs without being fertilised, and vegetative reproduction is when plant tissue grows into a new plant.

Bryophytes are nonvascular plants that are seedless, and do not form a monophyletic group (a clade). There favorable habitat is in moist soil and or tree bark which allows them to germinate and grow into gametophytes. They generally form into ground hugging carpet, because of the bryophytes lack of vascular tissue which is needed to transport water and nutrients in long distances. The thin structure allows bryophyte organs to
