A major distinction between prokaryotes and eukaryotes is the presence of membranebound organelles in eukaryotes. a. DESCRIBE the STRUCTURE and FUNCTION of FOUR of the following eukaryotic membranebound organelles. Include whether the organelles you have chosen are found in either animal cells or plants cells or both. 1. Nucleus
4. Golgi apparatus
7. Endoplasmic Reticulum (RER and SER)
b. Prokaryotic and eukaryotic cells have some nonmembranebound components in common. DESCRIBE the FUNCTION of TWO of the following and DISCUSS how each differs in prokaryotes and eukaryotes. ●
There are many eukaryotic membranebound organelles. The mitochondria is composed of an outer membrane, intermembrane and a matrix. The mitochondria is where aerobic respiration occurs and ATP is made. It does this by metabolising chemical components of the food that we eat into simpler molecules such as carbohydrates, fats, and protein. Mitochondria are found in both plant and animal cells. The vacuole is a large sac like organelle that is used for storage. in plants the vacuole is surrounded by a membrane known as the tonoplast. When vacuoles are filled with water in plants, they help contribute to the turgor of the cell and rigidity of a plant. Vacuoles tend to be quite large in plant cells but they are not so big in animal cells. Chloroplasts are specialized organelles found in all plant cells. These organelles contain the plant cell’s chlorophyll responsible for the plant’s green color and the ability to absorb energy from sunlight. this energy is used to convert water and atmospheric carbon dioxide into sugars which can be metabolized by the biochemical process ...
