Quick Answer: What Do Mitochondria And Chloroplasts Do?

What do Cristae do in mitochondria?

Mitochondrial cristae are the folds within the inner mitochondrial membrane.

These folds allow for increased surface area in which chemical reactions, such as the redox reactions, can take place..

What organelle does the mitochondria work with?

The contact points between the mitochondria and the ER are relatively stable. When the ER and mitochondria move along the cytoskeleton, the two organelles maintain contact with each other.

Why does the mitochondria have two membranes?

As previously mentioned, mitochondria contain two major membranes. The outer mitochondrial membrane fully surrounds the inner membrane, with a small intermembrane space in between. The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein.

Do animal cells have mitochondria and chloroplasts?

Both animal and plant cells have mitochondria, but only plant cells have chloroplasts. Plants don’t get their sugar from eating food, so they need to make sugar from sunlight. This process (photosynthesis) takes place in the chloroplast.

Can mitochondria and chloroplasts live independently?

Despite their many similarities, mitochondria (and chloroplasts) aren’t free-living bacteria anymore. The first eukaryotic cell evolved more than a billion years ago. Since then, these organelles have become completely dependent on their host cells.

Why do mitochondria and chloroplasts replicate independently?

Mitochondria and chloroplasts have their own DNA carried in plasmid-like structures. … These organelles make their own DNA and synthesize their own proteins independent of the rest of the cell.

How does the mitochondria and chloroplast work together?

How do the chloroplast and mitochondria work together to keep plant cells alive? Chloroplasts convert sunlight into food during photosynthesis, then mitochondria makes energy out of the food in the form of ATP. where critical chemical reactions occur in the cell that allow for the release of energy from food.

How does oxygen get into or out of chloroplasts and mitochondria?

oxygen is important in the reactions of both photosynthesis and cellular respiration. How does oxygen get into or out of the chloroplasts and mitochondria? … The inner membrane of the mitochondria is folded; these folds are called cristae.

What are the similarities and differences between chloroplast and mitochondria?

Mitochondria and chloroplast are organelles found in a plant cell. However, chloroplast is absent in an animal but mitochondria is found in both. Mitochondria generates energy for the cell in the form of ATP using oxygen and nutrients. Chloroplast is the site for photosynthesis in a plant cell.

Can mitochondria live independently?

However, mitochondria cannot survive outside the cell. … Mitochondria divide independently by a process that resembles binary fission in prokaryotes. Specifically, mitochondria are not formed de novo by the eukaryotic cell; they reproduce within the cell and are distributed between two cells when cells divide.

What products do the mitochondria make that the chloroplasts use?

1 Answer. Chloroplasts produce glucose during photosynthesis, which is broken down into ATP by the mitochondria during cellular respiration.

What is the function of the mitochondria?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Why Plants need both chloroplasts and mitochondria?

Cells need both chloroplasts and mitochondria to undergo both photosynthesis AND cell respiration. After photosynthesis, which chloroplasts are needed for, which yields oxygen and glucose, plants need to break down the glucose and they use cell respiration to do this, which happens in the mitochondria.

How do mitochondria generate energy?

Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. … NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP).

How are chloroplast and mitochondria the same?

Chloroplasts are very similar to mitochondria, but are found only in the cells of plants and some algae. Like mitochondria, chloroplasts produce food for their cells. … Like the mitochondria, the chloroplast has an inner and outer membrane.
