Can someone please help me to complete these questions?
proportion to find the diameters of the following cell at 40x, 10 reticule units-0.005 mm 2. Looking at the following cell, identify and give functions for all the organelles labeled here function: function function: D= function: Is this cell an autotroph or a heterotroph? What does the word autotroph mean? 3. If you had to tell another student how to tell whether a cell in the microscope is a eukaryotic or a prokaryotic cell, what would you say? What are they looking for?Explanation / Answer
Answer 1:
As we know , 10 reticule = 0.005mm
Or 1 reticule = 0.0005mm or 0.5 micro meter
At 40X, 0.5 micro m/40 =0.0125micro meter
Hence, the diameter of cell is 0.0125micro meter.
Answer 2: A is smooth endoplasmic reticulum ; Function: SER plays an important role in protein transportation and synthesis of lipids. Also involve in metabolism of calcium ions within the cell.
B is Chloroplast ; Function: These are the sites of photosynthesis. They use solar energy to produce sugars that can be used by cells for energy.
C is smooth endoplasmic reticulum ; Function: RER is involved in assembly, processing and export of proteins. These are called rough because of the ribosomes present on the surface of ER membrane.
D is mitochondria ; Function: Play a vital role in generating and transforming the energy and in plants these involve in photorespiration.
This cell is autotroph. Autotroph means the organism that can produce their own food from the inorganic sources using light energy (solar energy).
Answer 3. This is an eukaryotic cell, as we can observe nucleus, membrane bound organelles like mitochondria, chloroplast, golgi bodies and endoplasmic reticulum.
While in prokaryotes genetic information floats freely inside the cell wall and not contain membrane bound organelles.
Answer 10: This is the general structure for amino acid, in this R is the side chain which will be different for each 20 standard amino acids. These are the building block of proteins.
