Khadijah Isaacs7th prd09/24/2013 What are Nuc, Flag, ER, Mito, Chlora, Golgi, Ves and Lys short for? Nuc is short for nucleus; Flag stands for flagella; ER stands for endoplasmic reticulum; Mito is short for mitochondria; Golgi is short for golgi apparatus; Last but not least, Lys is short for lysosomes; What does each of these organelles do in a cell? the nucleus is the control in the cell. the flagella is used to move the cell. the endoplasmic reticulum is used for helping things travel in the cell. the mitochondria is in charge of making energy. Golgi does the moving chemicals around in the cell. the vesicle is used to store things. a lysosome is used to break up food in the cell.

What is the autogenic hypothesis of the origin of the eukaryotic cell? The autogenic hypothesis is that a prokaryotic cell slowly but surely evolved on its own to the eukaryotic cell.

What is the evidence that supports the autogenic hypothesis? When Lito Mito went to search in the library and it talks about how they were created from something that already exist.

What is the endosymbiotic hypothesis? The endosymbiotic hypothesis is that a prokaryotic cell ate smaller organelles which evolved into what they are today.

What is the evidence for the endosymbiotic hypothesis? The evidence that supports this is because mitochondrion and chloroplast both have a brother cell; the cells are extremely alike. The brother cell is a prokaryotic cell.

What are the comparative strengths and weaknesses of the two hypotheses?The comparative strengths and weaknesses of the two hypotheses are that there are ways that we could reenact the cell eating the other little prokaryotic.
