Photoreceptor and eye point
The front end of the feeding port is Euglena cells solid food particles and dissent. But it is certain that too much water can be discharged from the body through the cytoplasm of the cell. There is a large expansion bubble next to the savings bubble, and its main function is to adjust the water balance. Collect too much water in the cytoplasm. Drained into the savings bubble and expelled from the mouth.

It may have a certain effect on the quality of water when it is propagated in large quantities.

Reproduction of Protista
The reproductive method is generally two longitudinal splitting of euglena,. First, the nucleus is mitotic, and the nuclear membrane does not disappear when the mitosis is split. The basal body replicate to two. After that, the worm begins to split from the front end, and the flagellum is stripped off. Meanwhile, the new flagellum is regenerated from the basal body, or the old flagellum is preserved, and the other produces new flagellum. The cell mouth is also split to two, and then continues to split from the front and back and disconnects into 2 individuals. When the environment is suitable, the body breaks out and divides once or several times before the bursa is out. On the formation of cysts through adverse Euglena environment is a good adaptation.

Mobility of Protista
There is a cell in the front end of the body. A swollen savings bubble is extended back, and a flagellum is extended from the mouth of the cell. Flagellum is the protruding of the surface of an active cell. The swing movement by flagellate euglena.

The ecological role of Protista
Protists can grow as fast as, or faster than their phytoplankton prey. Recent estimates of microzooplankton herbivory in various parts of the sea suggest that protists routinely consume from 25 to 100% of daily phytoplankton production, even in diatom-dominated upwelling blooms. Phagotrophic protists should be viewed as a dominant biotic control of both bacteria and of phytoplankton in the sea.

The method of obtaining nutrients of Protista
The cells of protists need to perform all of the functions that other cells do, such as grow and reproduce, maintain homeostasis, and obtain energy. They also need to obtain "food" to provide the energy to perform these functions.

The type of cell of protista
Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues. They could be viewed as those eukaryotes that cannot be classified as one of the other cell types. They include the one-celled animal-like protozoa, one-celled algae, slime molds and water molds.

Fungi in our daily life
In our daily life, we always see fungi around us. For example, we usually have mushroom for meals. In forest where is moist, we can find fungi on trees, ground. Fungi can be very beautiful and have magic color. But some of them is poisonous.

Motility of fungi
Spores and/or gametes can be motile or not. However, in the strict sense as fungi are currently defined, only those organisms that produce nonmotile spores and gametes are classified as fungi. Nevertheless, we will be going over organisms that have motile spores, called zoospores, and motile gametes.

Diseases or impacts of fungi on humans
Fungi also cause a number of plant and animal diseases: in humans, ringworm, athlete's foot, and several more serious diseases are caused by fungi. Because fungi are more chemically and genetically similar to animals than other organisms, this makes fungal diseases very difficult to treat. Plant diseases caused by fungi include rusts, smuts, and leaf, root, and stem rots, and may cause severe damage to crops.

The ecological role of fungi
Fungi is important both in terms of their ecological and economic roles. By breaking down dead organic material, they continue the cycle of nutrients through ecosystems. In addition, most vascular plants could not grow without the symbiotic fungi, or mycorrhizae, that inhabit their roots and supply essential nutrients.

The method of how fungi obtaining nutrients
They decompose dead wood and other tough plant material. Fungal hyphae are adapted to efficient absorption of nutrients from their environments, because hyphae have high surface area-to-volume ratios. ... Some fungi digest nutrients by releasing enzymes into the environment.

The environment fungi Like
Most fungi prefer moist locations, but again there are exceptions, such as the fungi that grow on dried grains. Mushrooms like the dark, but rusts and mildews can grow in sunlight. The environmental requirements are fungus-specific.

Type of fungi cells
Each hypha consists of one or more cells surrounded by a tubular cell wall. A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa

The reproduction of fungi
Asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. Somatic cells in yeast form buds.
