If endosymbiosis generated mitochondria and chloroplasts from an ancestral proteobacteria and cyanobacteria, respectively, speculate as to why an endosymbiotic event never generated an organelle specifically tasked for cellulose degradation in eukaryotic cells. Strictly no plagiarism.

Please answer fast

In secondary endosymbiosis, the plastid organelle is derived from engulfing Prokaryotic algal cell. an True False

The most interesting bacterial group according to Dr. Bragg would be: The Deltaproteobacteria The Firmicutes O The Gammaproteobacteria O The Cyanobacteria All of the following are true statements about events that occur in the apicomplexan life cycle EXCEPT: All of these statements are true. O the sporozoite is the motile infective stage often two completely different organisms host different stages of the life cycle the life cycles include both sexual and asexual stages

Cilia and flagella have several functions. These include (choose all that apply) they have many functions, but they are found only on eukaryote organisms O membrane transport proteins embedded in the cell membranes of prokaryote organisms a means of creating a current in the mucous layer surrounding lung cells V a means of locomotion

Do question 5

Illustrate and explain the evidence supporting the predominant Theory on the origin of energetic organelles in Eukaryotes.

Please help to answer and also provide a step-by-step explanation: Movement is a type of response to stimuli. Many unicellular organisms can move in response to chemical changes outside the cell – amoeba exhibits locomotion, paramecium use cilia to get around. Protists such as the Amoeba and the Paramecium are important to our discussion of evolution because of their ability to respond to changes in the environment. These single-celled eukaryotes have this ability because a) their DNA responds to stimuli from the environment, b) they have the same germ cell layers that the Cnidaria have, c) new proteins, located in the cell membrane, have shapes and charge patterns that react to a stimulus by generating an electrical impulse. d) they have a Golgi Apparatus that measures the stimulus from the environment, e) none of these are possible.
