What else can I help you with?
Name any two organelles that are self-replicating?
Mitochondria and chloroplasts.
How are chloroplasts and mitochondria similar to bacteria?
Chloroplasts and mitochondria have their own DNA and ribosomes, similar to bacteria. They also reproduce independently within the cell through a process resembling binary fission, just like bacteria. Additionally, both organelles are thought to have originated from endosymbiotic relationships with ancient bacterial cells.
How did mitochondria and chloroplasts most likely arise in eukaryotic cells?
Mitochondria and chloroplasts most likely arose in eukaryotic cells through a process called endosymbiosis, where a host cell engulfed a prokaryotic cell. Over time, the prokaryotic cell evolved to become an organelle within the host cell, forming a symbiotic relationship. This theory is supported by the similarities between mitochondria and chloroplasts and modern-day bacteria.
Which organelles outside the cell nucleus contain genetic material?
chloroplasts and mitochondriaThey have their own DNA and can also reproduce by themselves inside the cell. That is why many scientist believe that the were once individual cells.
Which do animal cells not have a mitochondria chloroplasts a nucleus or a cell membrane?
Animal cells do not have chloroplasts, which are a structure only found in plant cells. Chloroplasts are responsible for photosynthesis, a process where plants convert sunlight into energy.
What is the manufacturers of the cell?
Mitochondria in animal Cells, and within both mitochondria and chloroplasts in plant Cells.
Name any two organelles that are self-replicating?
Mitochondria and chloroplasts.
How do chloroplasts and mitochondria work together in a plant cell?
Chloroplasts are responsible for photosynthesis, converting sunlight into chemical energy. Mitochondria then use this energy to generate ATP through cellular respiration. Together, they maintain the energy balance within the cell, with chloroplasts producing energy and mitochondria utilizing it efficiently.
Why do animal cells not have chloraplast?
Chloroplasts (as well as Mitochondria) are endosymbionts. This means that they are cells, living within another cell. Historically, eukaryotic cells had no mitochondria or chloroplasts (and mitochondria and chloroplasts existed by themselves outside of cells). The current hypothesis is that a cell tried to engulf a mitochondria (by phagocytosis) but failed in digesting it. Over time, some of the mitochondrial DNA (mtDNA) became part of the host cell's genome. This cell is a common ancestor to both plants and animals, which is why both have mitochondria. A cell with mitochondria then did the same thing with chloroplasts, absorbing one, and taking some of its ctDNA etc. Because not all cells that had mitochondria absorbed chloroplasts there were cells with mitochondria only, and cells with mitochondria and chloroplasts. The ones with chloroplasts evolved to become plant cells, and those without evolved to become animal cells.
What parts of a cell do scientists think were once free-living organisms?
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
What do mitochondria and chloroplasts do for a cell?
mitochondria provide power for cells chloroplasts provide food for cells by photosynthesis
What organelle may survive and reproduce independently of a cell?
Mitochondria are organelles that were once free-living bacteria. They can survive and reproduce independently in certain conditions, suggesting they have retained some autonomy from the host cell.
The mitochondria and chloroplasts are examples of this?
Parts of the cell
Mitochondria and chloroplasts are an example of this?
Parts of a cell.

Name 2 cell organelles having DNA?
The two cell organelles that have DNA are the mitochondria and the chloroplasts. Mitochondria are responsible for producing energy in the cell, while chloroplasts are found in plant cells and are responsible for photosynthesis.
