Lab 10 – Cell Structure and Function

September 16, 2020

Pre-Lab Questions: 1.) Similarities – both eukaryotic and prokaryotic cells contain ribosomes, cytoplasm’s, and cell membranes Differences – eukaryotic cells contain more organelles and functions, prokaryotic cells don’t contain a nucleus, prokaryotic cells have a different arrangement of genes on the chromosome 2.) DNA in a prokaryotic cell – exists in the cytoplasm because it doesn’t contain a nucleus DNA in a eukaryotic cell – exists in the nucleus 3.) Cell membrane, cell wall, and cytoskeleton Experiment 1: Identifying Cell Structures Post-Lab Questions: 1a.) Chromosomes b.) Nucleus c.) Cytoplasm d.) Cell Wall 2.) Difference – rough endoplasmic reticulum is known for storing only proteins and is found near the cell membrane while smooth endoplasmic reticulum is known for storing proteins and lipids and is found near the cytoplasm 3.) An animal cell would not be able to survive without the mitochondria because the cell would not be able to convert food into energy 4.) A specimen with a cell wall and no nucleus or mitochondria would be considered a prokaryotic cell 5.) Leaves are green because they generate sunlight into energy because they have chlorophyll. Roots are not green because they are underground and do not have to generate sunlight into energy, therefore they do not need chlorophyll Experiment 2: Create A Cell Post-Lab Questions: 1.) Chloroplast and a cell wall 2.) Yes; a plant cell contains a cell wall and chloroplast whereas an animal cell does not 3.) Cilia and cytoplasm 4.) They have certain functions to support the way a cell lives 5.) Cell wall surrounds the cell - supports/protects the cell Nucleus is in the center of the cell – provides “power” to the rest of the cell Chloroplast is located near the edge of the cell – collects sunlight to convert to energy
