Are chloroplast found in photosynthetic protists?

Are chloroplast found in photosynthetic protists?

Chloroplasts are found only in plants and photosynthetic algae. (Humans and other animals do not have chloroplasts.) The chloroplast’s job is to carry out a process called photosynthesis.

Do photosynthetic cells need mitochondria?

Mitochondria fulfill important functions in photosynthetic cells not only in darkness but also in light. Furthermore, during photosynthesis mitochondrial electron transport is important for regulation of the redox balance in the cell.

Where are mitochondria found in plants?

Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.

Do photosynthetic eukaryotes have mitochondria and chloroplasts?

Some groups of eukaryotes are photosynthetic. Their cells contain, in addition to the “standard” eukaryotic organelles, photosynthetic organelles called chloroplasts. Like mitochondria, chloroplasts appear to have an endosymbiotic origin.

Which came first the mitochondria or chloroplast?

The mitochondria and plastids originated from endosymbiotic events when ancestral cells engulfed an aerobic bacterium (in the case of mitochondria) and a photosynthetic bacterium (in the case of chloroplasts). The evolution of mitochondria likely preceded the evolution of chloroplasts.

What plants have mitochondria?

The short answer is yes. Mitochondria is found in plants. Plant and animal cells both have mitochondria the only difference being plant cells additionally have chloroplasts.

Why do you find mitochondria in photosynthetic tissue?

Why do you find mitochondria in photosynthetic tissue? Mitochondria are not needed but are an evolutionary relic. Mitochondria and chloroplasts work together to use light energy to make sugars. Mitochondria participate in the Calvin cycle/light independent reactions of photosynthesis.

Why do photosynthetic grasses have both chloroplasts and mitochondria in their cells?

Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light (solar) energy into chemical energy during photosynthesis, while mitochondria, the powerhouse of the cell produces ATP- the energy currency of the cell during respiration.

What is inside the mitochondria?

A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The inner mitochondrial membrane, The cristae space (formed by infoldings of the inner membrane), and. The matrix (space within the inner membrane), which is a fluid.

What cells are mitochondria found in?

Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria. A few types of cells, such as red blood cells, lack mitochondria entirely.

Are mitochondria prokaryotic or eukaryotic?

No, prokaryotes do not have mitochondria. Mitochondria are only found in eukaryotic cells. This is also true of other membrane-bound structures like the nucleus and the Golgi apparatus (more on these later).

Do all eukaryotes have mitochondria?

Mitochondria are found in the cells of nearly every eukaryotic organism, including plants and animals. Cells that require a lot of energy, such as muscle cells, can contain hundreds or thousands of mitochondria.

Where do mitochondria and chloroplasts come from?

Mitochondria were derived from aerobic alpha-proteobacteriathat once lived within their cells. Many have chloroplastswith which they carry on photosynthesis. Chloroplasts were derived from photosynthetic cyanobacterialiving within their cells.

What kind of molds do protists live in?

The Euglenozoa The Alveolates Ciliates Sporozoans (Apicomplexa) Dinoflagellates The Stramenopiles Diatoms Golden Algae (Chrysophyta) Brown Algae Water Molds (Oomycetes) Red Algae (Rhodophyta) Slime Molds (Mycetozoa) Cellular Slime Molds Plasmodial Slime Molds (Myxomycetes) Protists without typical mitochondria Choanoflagellates

How many groups of protists are there in eukarya?

The emerging classification scheme groups the entire domain Eukarya into six “supergroups” that contain all of the protists as well as animals, plants, and fungi that evolved from a common ancestor (Figure 1).

Are there any protists that lack phycoerythrins?

Other protists classified as red algae lack phycoerythrins and are parasites. Both the red algae and the glaucophytes store carbohydrates in the cytoplasm rather than in the plastid. Red algae are common in tropical waters where they have been detected at depths of 260 meters. Other red algae exist in terrestrial or freshwater environments.
