Are diatoms photosynthetic?

Are diatoms photosynthetic?

Diatoms are known for their high photosynthetic efficiency particularly under fluctuating light conditions (Wagner et al., 2006).

What do cyanobacteria use for photosynthesis?

Cyanobacteria use the energy of sunlight to drive photosynthesis, a process where the energy of light is used to split water molecules into oxygen, protons, and electrons.

Which domain has photosynthetic cyanobacteria?

Cyanobacteria

What are diatoms responsible for?

Diatoms in the ocean are responsible for 20 percent of the oxygen we breathe and are an important source of food for small animals that in turn are food for fish. In addition, these small algae also play an important role in the oceans’ carbon and nitrogen cycles.

Do dinoflagellates use photosynthesis?

Dinoflagellates. Dinoflagellates are motile unicellular algae characterized by a pair of flagellae. Many dinoflagellates are photosynthetic, whereas others are mixotrophic. Dinoflagellates have been an important part of the marine phytoplankton since the mid-Mesozoic (Fig.

Is Volvox a photosynthetic?

Volvox carteri is classified as a species of green algae and is, therefore, a photoautotroph, obtaining its energy through photosynthesis. This process is carried out in the chloroplasts of each individual cell, converting sunlight, carbon dioxide, and water into oxygen and glucose.

Which of the following organisms is photosynthetic?

Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis.

Are diatoms producers?

Diatoms are one of the major primary producers in the ocean, responsible annually for ~20% of photosynthetically fixed CO2 on Earth.

Is diatoms photosynthetic or heterotrophic?

Energy source. Diatoms are mainly photosynthetic; however a few are obligate heterotrophs and can live in the absence of light provided an appropriate organic carbon source is available.

What is photosynthetic dinoflagellate?

Dinoflagellates are considered plants because they use sunlight as their main source of energy (photosynthesis). Photosynthesis: Our dinoflagellates, or ‘PyroDinos’ as we call them, use light as their main source of energy. Dinos use sunlight to synthesize foods from carbon dioxide (CO2) and water.

Is dinoflagellates photosynthetic or heterotrophic?

Nutrition among dinoflagellates is autotrophic, heterotrophic, or mixed; some species are parasitic or commensal. About one-half of the species are photosynthetic; even among those, however, many are also predatory.

Why is euglena photosynthetic?

Euglenas create their own food through photosynthesis, the process of absorbing sunlight to synthesize foods from carbon dioxide and water. An eyespot at the front end of the euglena detects light, and its chloroplasts (structures that contain chlorophyll) trap the sunlight, allowing photosynthesis to occur.

Are red algae photosynthetic?

Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments allow red algae to photosynthesize and live at somewhat greater depths than most other “algae”.

What organisms photosynthesize the most?

plants
The ability to photosynthesize is found in both eukaryotic and prokaryotic organisms. The most well-known examples are plants, as all but a very few parasitic or mycoheterotrophic species contain chlorophyll and produce their own food. Algae are the other dominant group of eukaryotic photosynthetic organisms.

What algae use photosynthesis?

The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella. Green algae in the genus Hyalotheca, a group of filamentous desmids (class Charophyceae), use chlorophyll to capture energy from sunlight for photosynthesis.

Which of the following pairs of organisms are photosynthetic?

Euglena and chlamydomonas are photosynthetic because the possess features of plants which enables them to produce their food.

Which of the following is produced by plants through photosynthesis?

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
