Straighterline BIO 201L Lab 2 Worksheet Lab 2 Cell Structure and Function 2022 | Complete | 100% Correct Answers

Document Content and Description Below

Pre-Lab Questions: “1. Identify the major similarities and differences between prokaryotic and eukaryotic cells. “ Both cells have cytoplasm, ribosoms and DNA as the major identifiers. They diff... er in the linearity of cell, eukaryotic are linear while prokaryotic are rounded. A nucleus is present in prokaryotic cells but not in the eukaryotic cells “2. Where is the DNA housed in a prokaryotic cell? Where is it housed in a eukaryotic cell? “ In prokaryotic cells the DNA is located in the nuceus. Due to the absence of the necleus in the eukarytic cells, the DNA is contained in the cytoplasm. “3. Name three structures which provide support and protection in a eukaryotic cell. “ support and protection is provided by the cell membrane, cytoskeleton and the cytoplasm Experiment 1: Cell Structure and Function Post-Lab Questions “1. Label each of the arrows in the following slide images: “ A- chromosomes B- nucleusLab 2 Cell Structure and Function BIO201L Onion root tip, 1000x. “2. What is the difference between the rough and smooth endoplasmic reticulum? “ Ribosomes are absent in the smooth endoplasmic reticulum while the rough endoplasmic reticulum surface is covered in ribosomes. “3. Would an animal cell be able to survive without a mitochondria? Why or why not? “ Mitocondria performs conversion of food energy to ATP and cell respiration, thus an animal cell cannot survive without mitochondria. “4. What is the function of a lysosome? “ Lysosomes functions as digesters of excess food particles and organelles. Experiment 2: Exploring Cell Size Record the cell radius and time to center of the cell in Table 2. Then, calculate the surface area, volume, and surface area:volume ratio (equations provided below).
