Chloroplasts are essential organelles found in plant cells that play a crucial role in plant growth and development. These green structures are responsible for photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, a pigment that captures light energy and uses it to produce glucose, the primary source of energy for […]
Lysosomes are membrane-bound organelles found in animal cells that play a crucial role in cellular waste management and recycling. They were first discovered by Belgian cytologist Christian de Duve in the 1950s, who coined the term “lysosome” to describe these structures. Lysosomes contain a variety of enzymes that are responsible for breaking down and recycling
Mitochondria are often referred to as the “powerhouse of the cell” due to their crucial role in cellular function. These small, double-membraned organelles are found in the cytoplasm of eukaryotic cells and are responsible for producing the majority of the energy needed by the cell. They play a vital role in cellular respiration, which is
The vacuole is a vital organelle found in the cells of both plants and animals. It is a membrane-bound structure that plays a crucial role in cellular biology. The term “vacuole” comes from the Latin word “vacuus,” meaning empty, as early scientists believed that these organelles were simply empty spaces within the cell. However, we
The endoplasmic reticulum (ER) is a complex and dynamic organelle found in eukaryotic cells. It plays a crucial role in various cellular processes, including protein synthesis and folding, lipid metabolism, calcium signaling, cellular stress responses, autophagy, and cell-to-cell communication. The ER is composed of a network of interconnected tubules and flattened sacs called cisternae. It
The prokaryotic flagellum is a whip-like appendage found on the surface of many bacteria. It is responsible for bacterial movement, allowing these microorganisms to navigate their environment and find optimal conditions for growth and survival. The flagellum is a complex structure that consists of several components, including a filament, a hook, and a basal body.
The term organism means anything that is living and all organisms whether they are plant, animal, bacteria are made of microscopic cells, each type with unique cell structure. Common Characteristics of all cells Cytoplasm Plasma Membrane Ribosomes Types of Cells Prokaryotic Cells Bacteria cell Pili Plasmids Nucleoid Bacteria Cell Wall Capsule Prokaryotic Flagellum Eukaryotic
