What is the primary function of the cell membrane in human cells?
✔✔ To regulate the movement of substances in and out of the cell, maintaining homeostasis.
How do mitochondria contribute to cellular function?
✔✔ They produce adenosine triphosphate (ATP), which provides energy for cellular processes.
What is the role of ribosomes in protein synthesis?
✔✔ Ribosomes facilitate the translation of messenger RNA (mRNA) into polypeptides, forming
proteins.
What is the function of the endoplasmic reticulum in the cell?
1
,✔✔ The endoplasmic reticulum is involved in the synthesis of lipids and proteins, and the
processing and transport of cellular materials.
How does the Golgi apparatus modify proteins?
✔✔ It modifies, sorts, and packages proteins and lipids received from the endoplasmic reticulum
for secretion or delivery to other organelles.
What is the purpose of lysosomes in cellular processes?
✔✔ Lysosomes contain enzymes that break down waste materials and cellular debris.
How does the cytoskeleton contribute to cell structure?
✔✔ The cytoskeleton provides structural support, helps maintain cell shape, and facilitates cell
movement and division.
What is the primary role of the nucleus in eukaryotic cells?
2
, ✔✔ The nucleus houses the cell’s genetic material (DNA) and is responsible for regulating gene
expression and cell replication.
How do cellular junctions contribute to tissue function?
✔✔ Cellular junctions provide structural connections between cells, allowing them to function as
a cohesive unit and facilitating communication.
What is the role of the plasma membrane's phospholipid bilayer?
✔✔ The phospholipid bilayer forms the basic structural component of the plasma membrane,
creating a semi-permeable barrier that controls substance movement.
Midline ✔✔An imaginary line drawn down the center of the body, dividing it into right and left
halves
Medial ✔✔Toward the midline of the body
Lateral ✔✔To the side, away form the midline of the body
