What is the cell wall?

The cell wall is a rigid layer surrounding the cell membrane of plant cells, fungi, and some bacteria. It provides structural support and protection for the cell, helps maintain cell shape, and regulates the passage of molecules in and out of the cell. Made primarily of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria, the cell wall plays a crucial role in maintaining the integrity and function of the cell.

What is the cell membrane?

The cell membrane, also known as the plasma membrane, is a semi-permeable barrier that surrounds the cell, separating its internal environment from the external environment. It consists of a double layer of lipids embedded with proteins that regulate the passage of substances in and out of the cell, allowing the cell to maintain its internal environment and communicate with its surroundings.

What is the nucleus?

The nucleus is a membrane-bound organelle found in eukaryotic cells that contains the cell's genetic material, including DNA. It serves as the control center of the cell, regulating gene expression and coordinating cellular activities. The nucleus also plays a crucial role in cell division, as it ensures the accurate distribution of genetic material to daughter cells.

What is the cytoplasm?

The cytoplasm is a gel-like substance found within cells that houses organelles, such as the nucleus, mitochondria, and ribosomes. It is responsible for maintaining the cell's shape, supporting organelles, and facilitating various cellular processes, including metabolism and protein synthesis.

What are chloroplasts?

Chloroplasts are organelles found in plant cells and other photosynthetic organisms that are responsible for the process of photosynthesis. These oval-shaped structures contain chlorophyll, a pigment that captures sunlight and converts it into energy. During photosynthesis, chloroplasts convert carbon dioxide and water into glucose and oxygen using the energy from sunlight.

What is the endoplasmic reticulum?

The endoplasmic reticulum is a network of membranes found in eukaryotic cells that is involved in protein synthesis, lipid metabolism, and detoxification. It consists of two types: rough endoplasmic reticulum, which has ribosomes attached to its surface and is involved in protein synthesis, and smooth endoplasmic reticulum, which lacks ribosomes and is involved in lipid metabolism and detoxification processes.

What are Golgi apparatus?

The Golgi apparatus is an organelle found in eukaryotic cells responsible for packaging, modifying, and transporting proteins and lipids within the cell. It consists of a series of flattened membrane-bound sacs called cisternae, where proteins and lipids synthesized in the endoplasmic reticulum are processed and sorted before being sent to their final destination within or outside the cell.

What are ribosomes?

Ribosomes are cellular organelles responsible for protein synthesis in all living cells. They read the genetic information in mRNA and use it to assemble amino acids into proteins. They can be found floating freely in the cytoplasm or attached to the endoplasmic reticulum in eukaryotic cells, and are composed of two subunits made up of rRNA and proteins.

What is the mitochondria?

The mitochondria are membrane-bound organelles found in the cells of eukaryotic organisms, responsible for generating the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy. Known as the powerhouse of the cell, mitochondria play a crucial role in cellular respiration and metabolism, converting nutrients into energy through a series of biochemical reactions.

What are vacuoles?

Vacuoles are membrane-bound organelles found in the cells of plants, fungi, and some protists. They are responsible for various functions within the cell, such as storing nutrients, maintaining turgor pressure, and aiding in the digestion and removal of waste products. Vacuoles can also help regulate the pH balance and assist in the detoxification of harmful substances within the cell.
