Why are mitochondria and plastids called semiautonomous membrane?
Mitochondria and plastids are called semiautonomous because they contain their own DNA and ribosomes, allowing them to partially control their own replication and functioning. However, they still rely on the cell for certain essential components and cannot survive independently. The membrane part refers to their double-membrane structure that surrounds the organelles.
Which organelle is used to store chromosomal DNA?
In animal cells, the organelle that has its own DNA is mitochondria. However the main DNA and chromosomes are located in the nucleus of the cell which are responsible for cellular reproduction. In plant cells the plastids as well as mitochondria has DNA but in this case also the nucleus has the main DNA. It should be noted that plastids are prsent only in the plant cells
What are facts about plastid?
Plastids are organelles found in plant cells that are responsible for processes such as photosynthesis, storage of nutrients, and synthesis of pigments. They have their own DNA and are believed to have originated from endosymbiotic cyanobacteria. Plastids can change their function and structure depending on the developmental stage and environmental conditions of the plant cell.
Mitochondria and plastids likely formed in eukaryotes in what way?
Mitochondria likely formed through endosymbiosis with an aerobic bacterium, while plastids likely formed through endosymbiosis with a photosynthetic cyanobacterium. Both organelles have their own DNA and replicate independently within eukaryotic cells.
What Contains DNA in the form of chromosomes?
The nucleus of a cell contains DNA in the form of chromosomes. Chromosomes are structures made up of tightly-coiled DNA and proteins, and they are responsible for carrying an organism's genetic information.
What is the difference between Mitochondria and plastids?
The similarity between the two is that both of them have their own DNA and ribosomes. Therefore, they are able to prepare their own protiens. Plastids and Mitochondria have a similar external structure. Both have two membrane covering instead of just one.

What organelles are associated with endoymbiont theory?
Plastids (include chloroplasts) and mitochondria contain their own DNA are considered to be endosymbionts. Some think that flagella and cilia may also be but that is rather controversial. Those plastids that contain pigments can carry out photosynthesis. Plastids can also store products like starch and can synthesize fatty acids.

What are plastids?
Plastids are organelles found in plant cells that are responsible for processes such as photosynthesis, storage of starch, and synthesis of pigments. They have their own DNA and are classified into different types, including chloroplasts, chromoplasts, and leucoplasts.

How are mitchondria and chloroplasts similar?
Mitochondria and chloroplast are botn thought to be what remains of ancient bacteria. They are both about the size of a bacteria and both of them contain their own DNA. Mitochondria is responsible for cellular respiration using the sugar generated in the chloroplasts.
Mitochondria and plastids likely formed in eukaryotes in what way?
Mitochondria likely formed through endosymbiosis with an aerobic bacterium, while plastids likely formed through endosymbiosis with a photosynthetic cyanobacterium. Both organelles have their own DNA and replicate independently within eukaryotic cells.

Is ctyolasm the same thing as plastid?
No, cytoplasm and plastid are not the same. Cytoplasm is the fluid inside a cell that contains organelles, while plastids are a specific group of organelles found in plant cells (like chloroplasts). Plastids have their own DNA and are responsible for functions like photosynthesis in plants.
What is the nickname for mitchondria?
The nickname for mitchondria is the powerhouses of the cell
What is plastidome?
The plastidome refers to the complete set of plastid genes present in an organism's genome. Plastids are organelles found in plant cells that have their own DNA and are involved in processes like photosynthesis and storage of nutrients. Studying the plastidome can provide insights into the evolutionary history of plants and their adaptations to different environments.
