What is the basic unit of life?

The basic unit of life is the cell. Cells are the smallest functional and structural unit of all living organisms, carrying out essential processes that are necessary for life, such as metabolism, growth, and reproduction.

What is the function of the cell membrane?

The cell membrane serves as a protective barrier that encloses the cell and controls the passage of substances in and out of the cell. It regulates the flow of nutrients, ions, and waste products, while also providing structural support and facilitating cell communication. This selectively permeable membrane enables the cell to maintain its internal environment, allowing necessary processes such as cellular respiration and protein synthesis to occur efficiently.

What is the role of the nucleus?

The nucleus is the control center of a cell, responsible for managing all cellular activities. It contains genetic material in the form of DNA, which serves as instructions for the cell's functions and development. The nucleus regulates gene expression, controls protein synthesis, and plays a vital role in cell division and growth. Essentially, the nucleus governs the overall functioning and maintenance of the cell, making it an essential component for cell survival and functioning.

What are mitochondria and what is their function?

Mitochondria are membrane-bound organelles found in the cytoplasm of eukaryotic cells. They are often referred to as the powerhouse of the cell because their main function is to generate adenosine triphosphate (ATP), which is the energy currency of the cell. Mitochondria carry out aerobic respiration, a process that involves breaking down nutrients to produce ATP through the electron transport chain and oxidative phosphorylation.

Describe the structure and function of the endoplasmic reticulum.

The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs found in eukaryotic cells. It has two regions - rough ER, studded with ribosomes for protein synthesis, and smooth ER, involved in lipid synthesis and detoxification. The ER plays a crucial role in protein folding, maturation, and transport, as well as lipid metabolism and calcium storage. It acts as a highway for molecules to move within the cell and helps maintain cellular homeostasis by regulating the synthesis and transport of various molecules.

What are ribosomes and what is their role in protein synthesis?

Ribosomes are cellular organelles responsible for protein synthesis in a cell. They are composed of two subunits and can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information carried by messenger RNA (mRNA) and use this information to assemble amino acids into a specific sequence, thereby forming a protein. This process, known as translation, is essential for the growth, maintenance, and repair of the cell.

Describe the structure and function of the Golgi apparatus.

The Golgi apparatus is a cellular organelle composed of stacks of flattened membranes called cisternae. Its main function is to process and package proteins and lipids that are synthesized by the endoplasmic reticulum. It modifies these molecules by adding sugars and other groups to them, sorts them into vesicles, and then sends them to their final destination within the cell or outside of it. Additionally, the Golgi apparatus plays a role in the synthesis of certain complex molecules and the recycling of cellular components.

What is the purpose of lysosomes in a cell?

Lysosomes are membrane-bound organelles that contain digestive enzymes. Their main purpose in a cell is to digest and break down various molecules, including old organelles, foreign substances, and cellular debris. This process helps maintain cellular homeostasis by recycling nutrients and eliminating waste products. Additionally, lysosomes play a crucial role in cellular renewal, autophagy, and defending against pathogens.

Explain the function of vacuoles in plant cells.

Vacuoles in plant cells serve multiple functions, such as storing nutrients, regulating turgor pressure to maintain cell shape and rigidity, isolating and degrading waste products, and controlling the pH levels of the cell. Additionally, vacuoles can also act as storage for pigments, toxins, and defensive compounds, as well as help in plant growth and development by storing crucial molecules like proteins and carbohydrates. Overall, vacuoles play a critical role in supporting various cellular activities and contributing to the overall health and function of the plant cell.

What are the differences between plant and animal cells?

Plant cells have a rigid cell wall made of cellulose and chloroplasts for photosynthesis, while animal cells do not have a cell wall and lack chloroplasts. Plant cells typically have a large central vacuole for storage and structure, whereas animal cells have multiple smaller vacuoles. Additionally, plant cells have a rectangular or square shape, while animal cells are typically round or irregular in shape. Both types of cells have a nucleus, mitochondria, and other organelles, but the specific structures and functions may vary between plant and animal cells.
