Eukaryotes are important because the mitochondria in them provides energy to cells by converting ingested sugars into adenosine triphosphate (ATP). ATP is a complex organic chemical that creates and transfers energy from one cell to another.

Eukaryotic cells are very diverse in shape, form and function. Some internal and external features, however, are common to all. These include a plasma (cell) membrane, a nucleus, mitochondria, internal membrane bound organelles and a cytoskeleton.

['They are multicellular organisms which do not possess chlorophyll.', 'They are eukaryotic organisms.', 'Cell wall is absent.', 'Mode of nutrition is heterotrophic i.e. they depend on other organisms for food.', 'They have muscle cells due to which they have the capability to contract and relax the body parts.']

Chlorophyll and accessory pigments allow algae to harvest and use the energy from sunlight. What are the distinguishing features of the major phyla of unicellular algae ("plantlike protists") ? * "Euglenophytes" are "plantlike" protists that have 2 flagella but no cell wall.

Domain Eukarya This domain is most familiar to use because it includes humans and other animals, along with plants, fungi, and a lesser-known group, the protists. Unlike the other domains, Domain Eukarya contains multicellular organisms, in addition to unicellular species.

Root hair cells are specialised (to perform a specific function). Their structure allows the plant to absorb more water. They also allow a plant to take in the minerals it needs to survive.

The Euglena is unique in that it is both heterotrophic (must consume food) and autotrophic (can make its own food). Chloroplasts within the euglena trap sunlight that is used for photosynthesis, and can be seen as several rod like structures throughout the cell.

Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules. Coelenterates (phylum Cnidaria) are radially symmetrical, with two tissue layers (ectoderm and endoderm) surrounding an all-purpose gastrovascular cavity.

For single-celled eukaryotes, cilia and flagella are essential for the locomotion of individual organisms. ... In eukaryotic cells, cilia and flagella contain the motor protein dynein and microtubules, which are composed of linear polymers of globular proteins called tubulin.

Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. All live in water, and move by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants.

Characteristic parts of vascular plants include roots, stems, leaves and vascular tissue (xylem and phloem). These highly specialized parts play a critical role in plant survival. The appearance of these structures in seed plants differs greatly by species and niche.

The paramecium is a unicellular eukaryote. Eukarya is the only domain that consists of multicellular and visible organisms, like people, animals, plants and trees. It's also the domain of many microorganisms, like fungi, algae and micro-animals.

['Division Bryophyta. These include mosses and liverworts.', 'Division Pteridophyta. These include the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.']

The species of the euglena often serves as the best member for the study of the algae as well as the protozoa. Most of the species of the euglena have the chloroplast for the photosynthesis purpose to produce their own food. They often derive their nutrition heterotrophically like other animals.

Why is euglena known as mixotroph? Mixotrophs are those organisms which show more than one mode of nutrition. Eugena is a mixotroph as it shows saprotrophic and autotrophic mode of nutrition. All euglena have chloroplasts and can make their own food by photosynthesis.
