1.Without using any resources other than your memory, what do you currently know about your chosen cell part? What do you remember about what your cell part does/function?

2. What unanswered questions do you have / what are you curious about your cell part?

(You might have questions such as--- How does it form? How do proteins get to it? What happens to it during cell division? How many membranes surround it? etc. - whatever you are curious about!)

Expert Solution

Mitochondria:

It is present in cytoplasm.

it is a cell organelle present in cytoplasm in the shape and size of Mitochondria depends upon the type of cell.

the number of Mitochondria present in cell also depends on the type of cell.

mitochondria is a double membrane bound cell organelle, only present in eukaryotes.

Two membranes:

1. Outer plasma membrane.

2. Inner plasma membrane.

A particular space is present between outer and inner membrane call as perimitochondrial space.

In the inner membrane a fluid is present called as matrix.

the matrix of Mitochondria have its own double stranded circular DNA. Multiple genes are present for the functioning of Mitochondria.

Eukaryotic mitochondria contains 70s ribosomes.

The inner membrane of Mitochondria have multiple integral proteins in the membrane have important role in energy profuction.

Function:

in the mitochondria energy is produced in the form of ATP by the use of multiple proteins and complexes.

mitochondria is called as powerhouse of cell.

some reactions glucose conversion also occurs in mitochondria.

krebs cycle and electron transport system occurs in mitochondria.

mitochondria have its own DNA so these are able to produce proteins it is necessary for its functioning.

Mitochondria does not depends on nuclear genes for their proteins.

1. The part of the cell cycle where DNA is duplicated inside the nucleus in preparation for cell division? 2. Most of the cell's life cycle spent in which phase? 3. During this part of the cell cycle phase, no nuclear envelope is visible and chromosomes align in the center of the cell and attach the the spindle by their centromeres? 4. Chromosomes are separated and pulled apart during this period of the cell cycle?

An isolated nucleus from a cell is on a microscope slide and is surrounded by growth medium. The nucleus has a refractive index of 1.42, while the surrounding fluid has an index of 1.35. For a wavelength of 500 nm, what will be the relative phase shift between light that is transmitted through the center of the nucleus vs. light that goes through the fluid? Can you use this information to explain why the phase of the unretarded light needs...
