Prokaryotic and Eukaryotic Cells Worksheet
What is the main component of cell membranes?
The main component of cell membranes is phospholipids. These molecules have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves to form a lipid bilayer that surrounds and protects the cell.
What is the function of the mitochondria in a cell?
The mitochondria in a cell are responsible for producing energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. This energy is essential for the cell to carry out various functions, such as metabolism, growth, and maintenance. Additionally, mitochondria also play a role in regulating cell signaling, cell growth, and cell death.
How do plant cells differ from animal cells?
Plant cells differ from animal cells in several key ways. Plant cells have a rigid cell wall made of cellulose, which provides structural support and protection. They also have chloroplasts, specialized organelles that perform photosynthesis to produce energy from sunlight. Animal cells lack a cell wall and chloroplasts but have lysosomes for digestion and centrioles for cell division, which are typically absent in plant cells. Additionally, plant cells often have larger central vacuoles for storage and maintaining turgor pressure, while animal cells have smaller, more numerous vacuoles for various functions.
What is the purpose of the Golgi apparatus in a cell?
The Golgi apparatus in a cell acts as a cellular "post office" by receiving, modifying, sorting, and shipping proteins and lipids that are synthesized in the endoplasmic reticulum to their correct destinations within or outside the cell. It plays a vital role in protein processing, packaging, and distribution, ensuring that the cell's various functions are carried out effectively.
What is the role of ribosomes in protein synthesis?
Ribosomes play a crucial role in protein synthesis by functioning as the cellular machinery responsible for translating mRNA into proteins. They read the genetic code carried by mRNA and use transfer RNA (tRNA) molecules to assemble amino acids in the correct order, forming a polypeptide chain that ultimately folds into a functional protein. Ribosomes consist of two subunits that work together in a coordinated fashion to synthesize proteins based on the instructions encoded in the mRNA.
What is the function of the nucleus in a cell?
The nucleus in a cell serves as the control center, containing the cell's genetic material (DNA) and regulating gene expression. It plays a crucial role in cell division, growth, and reproduction by directing the synthesis of proteins and coordinating various cellular activities. The nucleus also helps maintain the integrity and stability of the genetic information within the cell.
How do endoplasmic reticulum and Golgi apparatus work together in protein transportation?
The endoplasmic reticulum (ER) synthesizes and folds proteins, then sends them to the Golgi apparatus for further processing and distribution. The Golgi apparatus modifies these proteins by adding sugars and other molecules to them, and then packages them into vesicles for transportation to their final destinations within or outside the cell. In this way, the ER and Golgi apparatus work together in a coordinated manner to ensure the proper processing and transportation of proteins within the cell.
What is the function of lysosomes in a cell?
Lysosomes are membrane-bound organelles that function as the cell's recycling centers by breaking down macromolecules such as proteins, lipids, and carbohydrates into smaller molecules that can be reused by the cell. Additionally, lysosomes are involved in the degradation of damaged organelles, pathogens, and cellular waste, playing a crucial role in maintaining cellular homeostasis and overall cell function.
How do cells maintain homeostasis?
Cells maintain homeostasis through various mechanisms such as regulating their internal environment, balancing nutrient intake and waste removal, controlling water and ion balance, and responding to external stimuli. They achieve this through processes like active transport to move substances across the cell membrane, communicating with neighboring cells through signaling pathways, and adjusting metabolic activities to adapt to changing conditions. Overall, these intricate regulatory mechanisms work together to keep the internal environment of the cell stable despite fluctuations in the external environment.
What is the difference between prokaryotic and eukaryotic cells?
The main difference between prokaryotic and eukaryotic cells is the presence of a nucleus and other membrane-bound organelles. Prokaryotic cells, found in bacteria and archaea, lack a defined nucleus and their DNA is found in the nucleoid region. They are generally smaller and simpler in structure compared to eukaryotic cells, which have a distinct nucleus containing genetic material enclosed within a membrane, along with various organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus. Eukaryotic cells are more complex and are found in plants, animals, fungi, and protists.
