Cells are the basic structural and functional units of all living organisms.
What is the cell theory?
The cell theory states that all living organisms are composed of cells, cells are the basic units of structure and function in living organisms, and new cells arise from pre-existing cells.
What are the two main types of cells?
The two main types of cells are prokaryotic cells and eukaryotic cells.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.
What are the components of a cell?
Cells are composed of a cell membrane, cytoplasm, and genetic material (DNA or RNA).
What is the function of the cell membrane?
The cell membrane regulates the movement of substances in and out of the cell and provides protection and support for the cell.
What are organelles?
Organelles are specialized structures within a cell that perform specific functions.
Give examples of organelles in a eukaryotic cell.
Examples of organelles in a eukaryotic cell include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.
What is the role of the nucleus?
The nucleus contains the cell's genetic material and controls the cell's activities.
What is the function of mitochondria?
Mitochondria are the powerhouses of the cell and are responsible for producing energy through cellular respiration.
What is the function of the endoplasmic reticulum?
The endoplasmic reticulum is involved in the synthesis, folding, modification, and transport of proteins in the cell.
What is the Golgi apparatus responsible for?
The Golgi apparatus processes, modifies, and packages proteins and lipids for transport within or outside the cell.
What is the function of lysosomes?
Lysosomes contain enzymes that break down waste materials and cellular debris.
Describe the process of cell division.
Cell division involves the replication of genetic material and the division of the cell into two daughter cells. The two main types of cell division are mitosis and meiosis.
What is the significance of stem cells?
Stem cells have the potential to develop into different cell types and are important for growth, development, and tissue regeneration.
Explain the concept of cell specialization.
Cell specialization refers to the process where cells differentiate and develop specific structures and functions to perform specialized roles within an organism.
