Organism is an independent type of life consisting of a single cell or a complex of cells, where in kinds of organism such as a bacterium, protista, fungus, plant or animal, in which organelles or organs function together to carry out a variety of life processes. Any individual animal, plant, bacterium, etc. with separate parts or systems that work together as a whole to sustain life and its operations. A system that is regarded as similar to a living organism in its structure or functions.
But let us talk about the Plantae.
Considering a kind of organism which is the plantae/plant into this environment. Around us, we can see a variety of plants. We can see that their leaves, stems, and fruits are different. Plantae has all the plants included. They are organisms that are eukaryotic, multicellular and autotrophic. A rigid cell wall is contained in the plant cell. Plants have the pigments of chloroplast and chlorophyll that are required for photosynthesis.
All plants are included in Plantae: mosses, ferns, conifers, flowering plants, and so on, a wonderful variety of different types. With over 250,000 species, they are second only to the Arthropoda in number. For a very long time, they were around. The plants first appeared in the Ordovician, but did not begin to mimic modern plants. There were a wide range of shapes and sizes of plants around them around 360 million years ago, including small creeping plants and tall forest trees.
The green color, the product of a pigment called chlorophyll, is the most striking, and significant, characteristic of plants. In order to absorb light energy, plants use chlorophyll, which fuels the production of food-sugar, starch and other carbohydrates. Without these sources of food, much of the earth's life will be unlikely. Mushrooms and algae would still exist, but there would be no fruits, vegetables, grains, or any animals (which also rely on plants for their food ultimately!)
The plantae have the following feature characteristics that we might consider as niches too:
• Plantae are non-motile. They make their autotrophs, it’s their own food.
• It also reproduces asexually or sexually through vegetative propagation. These are eukaryotes that are multicellular. The outer cell wall and a large central vacuole form the plant cell.
• Plants contain chlorophyll-called photosynthetic pigments found in the plastids. For anchorage, reproduction, support and photosynthesis, they have distinct organelles.
Color brown and red algae, liverworts, mosses, ferns and seedlings with or without flowers are found in Plantae. These comprise plastids with a photosynthetic pigment. Photosynthesis is the primary mode of nourishment. They construct a multicellular embryo from the zygote during development. The shaping of the ecosystem is another significant contribution made by plants. Without plants, think of a spot. The arctic wastelands, truly arid deserts, and the deep ocean are the only such locations on earth. From the tundra to the forest to the desert, everywhere else is covered with plants. Actually, it is the plants that first come to mind when we think of a specific landscape.
Niches and Habitat
Niches can be characterized as the spatial and temporal role of the ranges of water, light, nutrients and temperature, and neighborhood competition. This description can be made available for each resource within the gradients: arid-humid (water), oligotrophic-eutrophic (nutrients), sun-shade (light), cold-hot (temperature). The role an organism has in an ecosystem is an ecological niche. An organism's niche includes what resources it needs, how it will obtain these resources, the habitat in which it lives, and how it fits, such as its predators and prey, into the ecosystem. No two species can have an ecological niche that is the same.
There are 3 ecological niches Mesophytes, Xerophytes and Hydrophytes. Mesophytes is possible to find living in high densities. The various plants that live together are all in competition for light, water and minerals, and this abundance of mesophytes in the same habitat leads to increased resource competition. Next is Xerophytes. They are plants that, usually, live under conditions where water is scarce.
As they are exposed to arid and windy conditions, xerophytes have developed multiple adaptations to help preserve water. The third one is Hydrophytes, they are plants that thrive in aquatic environments where there is a surplus of water, including swamps and wetlands. As a consequence of their environment, hydrophytes have an excessive water supply, so this results in too much water being limited.
Consider what niche I would want to introduce your organism into is Hydrophytes.
Let us focus on Hydrophytes
As I’ve mentioned above, Hydrophytes are plants, like swamps and wetlands, that thrive in aquatic environments where there is a surplus of water. Hydrophytes have an excessive water supply as a consequence of their climate, so this results in too much water being restricted. This suggests that, as opposed to conserving water, the majority of adaptations in hydrophytes are to facilitate the flow of water out of the plant. Hydrophyte examples include: Sea Weeds, Lotus and Water lilies.
Three types of adaptations in hydrophytes are ecological, physiological, and anatomical. It modifies its structures such as leaves, stem, roots and cell physiology for survival in an aquatic habitat to adapt to the various aquatic environments such as freshwater, sea water, lakes, ponds. This relies on conditions such as water temperature, osmotic concentration, toxicity, flow, dissolved oxygen, nutrients, etc. All these factors can affect the growth of plant. Hydrophyte adaptation is a natural phenomenon that is important for all aquatic plants to survive according to their surroundings. Since different plants live in different environments, certain modifications are required in order to adapt to the changing climate. Similarly, in order to survive in various marine environments, hydrophytes also experience few changes in their morphology, physiology and anatomy.
Therefore, we can conclude that all living beings are subject to particular changes, whether aquatic or terrestrial, according to the environmental conditions of the world in which they have to live. Therefore, in their anatomy and physiology, hydrophytic plants often undergo a few changes in order to support life in an aquatic climate.
