The Elysia sea slugs are one of the species that have done this. These gorgeous green animals graze on algae and steal their chloroplasts. They then ingest the stolen plastids to make more energy for moving about and finding food.
Other organisms that have been shown to contain chloroplasts include: red blood cells from mammals; brown algae (seaweeds); diatoms (a type of seaweed); some bacteria; and some fungi.
Even though these other organisms can store oxygen using photosynthesis, they cannot use oxygen as a source of energy like we can. Instead, they use it in the process so they need to get their hands on other organisms' chloroplasts to do so.
There has been one animal species discovered so far that doesn't rely on others for its chloroplasts. This species is called "Isochroma deltoidea". It is a single-celled organism that lives in freshwater. Isochroma deltoidea makes its own proteins with the help of enzymes derived from sunlight. These proteins are used by the cell to build itself new parts - just like plants do with the help of water and sunlight - instead of stealing them from other organisms like most other animals do.
Sea slugs can be found in salt marshes in New England and Canada. The chloroplasts, like plants, employ chlorophyl to turn sunlight into energy, reducing the need to ingest food to obtain energy....
Volvox and Euglena are the two creatures that have chloroplasts and eyespots. Chloroplasts are plant cells' names for their own structure containing chlorophyll, which is responsible for photosynthesis. Eyespots are small, colored spots on Euaglena or Angiosperm plants where they absorb light energy before converting it into chemical energy. These spots can be any color but are usually brown or black.
Volvox are algal species in the genus Volvox that contain many tiny unicellular bodies called zooids. The word "volva" means "shell" in Latin. Each zooid contains a nucleus with genes coding for proteins necessary for survival of the organism as well as other cellular components such as membranes. Additionally, each zooid contains several structures called vacuoles that store food materials and minerals obtained through osmosis-the diffusion of water into the cell-and photosynthetic products released during the process of photophosphorylation. Vacuoles also provide space for division of cells without causing the cell to burst.
Euglena are unicellular organisms in the class Alveolata.
Chloroplasts, which may be seen as many rod-like structures throughout the cell, capture sunlight that is used for photosynthesis. Green chloroplasts should be colored and labeled. Euglena also possesses a light-detecting eyespot at the anterior end. It is seen near the reservoir. This structure is made up of several organelles including mitochondria, which are responsible for generating energy for cells. These must be present for euglena to live.
Euglena has no nucleus or other membrane-bound organelles. Therefore, it depends on its chloroplasts for reproduction. When exposed to light, the eyespot detects this presence and sends out an electrical signal that triggers growth and division of additional plastids. The resulting offspring continue this process in order to survive. Thus, chloroplasts provide essential components for life processes.
Euglena can grow in water that is both fresh and saltwater. However, it will not live in water with temperatures above 45 degrees Celsius (113 degrees Fahrenheit). It is found in lakes, ponds, and slow-moving streams everywhere in the world except Africa and Australia.
The protein content of euglena varies depending on how it is grown and processed. The flour made from whole dried euglena contains about 50 percent protein by weight. The flour made from the germ only contains about 15 percent protein.
A chloroplast is a green organelle found in the cells of various eukaryotes such as plants and algae. It is in charge of photosynthesis, which is the mechanism by which the organism obtains the energy it requires to exist. A chloroplast uses light energy to produce sugar from carbon dioxide (CO2) and water (H2O). The remaining parts of the cell then use this sugar for their own metabolism.
Chloroplasts are very similar to mitochondria: they are both membrane-bound bodies that contain their own genome and perform important functions for the cell. However, while mitochondria are responsible for generating energy for the cell, chloroplasts are involved in photosynthesis, the process by which plants obtain their nutrients from the environment. Photosynthesis occurs when sunlight hits the leaves of the plant and is absorbed by pigments called chlorophylls, which cause the plant to grow and reproduce. The leftover materials from photosynthesis are used by bacteria or other organisms living in the soil to create their own food. Thus, all plants need oxygen, water, nitrogen, phosphorus, and potassium in order to grow and be healthy.
Some animals also have small structures called chloroplasts that are similar to those found in plants but don't contain any photosynthetic machinery. These ancillary chloroplasts play an important role in some animals by producing hormones that control growth and development. For example, mice without functional chloroplasts fail to make any of the three main hormones that regulate their immune systems.
However, you may be surprised to learn that cichlids are known to devour a wide variety of plants that are commonly kept in aquariums. Many cichlid species are herbivores, and while their natural diet consists primarily of algae, they may find the aquarium plants you've purchased to be rather delectable as well. Whether or not they will consume your plants depends on a number of factors, such as food availability and type, but most cichlids are capable of eating some form of vegetation.
In addition to being vegetarian, many cichlids also go through periodic bouts of carnivory. During these periods, the fish may eat other cichlids or even larger animals such as frogs, snails, and worms. The amount of time that a cichlid spends as an herbivore versus carnivore varies depending on how much food is available in its environment. If there is enough food, then the cichlid will remain vegetarians; however, if no meat can be found, then the fish will switch over to a carnivorous lifestyle.
Many people keep cichlids as pets because they believe that these fish should live in an environment where they can swim in a lake or river and eat plants. However, since this isn't their natural habitat, cichlids need to be provided with meat or vegetable foods to supplement their natural diet of algae.
