What are 2 examples of endosymbiosis?

Examples include nitrogen rhizobia–legume association, some coral–dinoflagellate symbioses, and the partnership between tubeworms and chemosynthetic bacteria. In these cases, the host must ‘find’ its endosymbiont among the numerous microbes in the environment.

What are Endosymbiotic bacteria?

Endosymbiosis is a symbiosis in which one symbiont dwells within the body of the other. Usually, when talking about endosymbionts, we refer to bacteria or less frequently to fungi living inside the eukaryotic cell or simply inside the body.

What are evidences to support the Endosymbiotic theory?

There is broad evidence to show that mitochondria and plastids arose from bacteria and one of the strongest arguments to support the endosymbiotic theory is that both mitochondria and plastids contain DNA that is different from that of the cell nucleus and that they have their own protein biosynthesis machinery.

What are 3 pieces of evidence for the Endosymbiotic theory?

Numerous lines of evidence exist, including that mitochondria and chloroplasts have their own circular DNA (prokaryotes also have circular DNA), mitochondria and chloroplasts have a double membrane (the inner membrane would have initially been the ingested prokaryote’s single membrane, and the outer membrane initially …

What are the four types of evidence for evolution?

Evidence for evolution

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life.
Biogeography.
Fossils.
Direct observation.

Which of the following is the strongest evidence for Endosymbiotic theory?

Protein import is the strongest evidence we have for the single origin of chloroplasts and mitochondria. It is probably also the strongest evidence we have to sort out the number and nature of secondary endosymbiotic events that have occurred in evolution involving the red plastid lineage.

Do Mitochondria have their own DNA?

Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.

Which of the following is are possible sites of protein synthesis in a typical eukaryotic cell?

The nucleolus within the nucleus is the site for ribosome assembly. Ribosomes are found in the cytoplasm or are attached to the cytoplasmic side of the plasma membrane or endoplasmic reticulum. They perform protein synthesis. Mitochondria perform cellular respiration and produce ATP.

What are the 5 differences between plant and animal cells?

Plant cell	Animal cell
2. Have a cell membrane.	2. Have no chloroplasts.
3. Have cytoplasm.	3. Have only small vacuoles.
4. Have a nucleus.	4. Often irregular in shape.
5. Often have chloroplasts containing chlorophyll.	5. Do not contain plastids.

Are lysosomes in plant cells?

Lysosomes (lysosome: from the Greek: lysis; loosen and soma; body) are found in nearly all animal and plant cells. In plant cells vacuoles can carry out lysosomal functions.
