CELL: THE UNIT OF LIFE

The Golgi Apparatus – The Golgi cisternae are Concentrically arranged near the nucleus . Explain ? The Golgi apparatus, also known as the Golgi complex, is an essential organelle in eukaryotic cells involved in the processing, sorting, and packaging of proteins and lipids. It consists of a series of flattened, membrane-bound sacs called cisternae. These […]

Gram staining is a method used to classify bacteria into two groups based on the characteristics of their cell walls. Here’s a breakdown of the Gram staining process, which is best visualized with a flowchart: Fixation: Bacteria are fixed to a slide by heat. Primary Stain: Crystal violet stain is applied. Mordant: Iodine solution is

Mitochondria Line 1: Mitochondria (sing.: mitochondrion), unless specifically stained, are not easily visible under the microscope. Explanation: This line introduces mitochondria and highlights that they are challenging to see under a microscope without special staining techniques due to their small size and colorless nature. Line 2: The number of mitochondria per cell is variable depending

Ribosome Line 1: Ribosomes are the granular structures first observed under the electron microscope as dense particles by George Palade (1953). Explanation: This line introduces ribosomes and their key characteristics: They are granular structures (small, grain-like). They were first observed using an electron microscope, a powerful tool for viewing tiny structures within cells. They appeared

Golgi, Lysosome and Vacuole Line 1: Camillo Golgi (1898) first observed densely stained reticular structures near the nucleus. Explanation: This line introduces the historical context by mentioning Camillo Golgi, who first observed these structures in 1898. These structures were later named Golgi bodies or Golgi apparatus after him. Enrichment: Early microscopes did not have the

The Pistil, Megasporangium (Ovule) and Embryo Sac Line 1: As you may recall, a non-living rigid structure called the cell wall forms an outer covering for the plasma membrane of fungi and plants. Explanation: This line reminds you that plant and fungal cells have a cell wall external to the plasma membrane (cell membrane). This

Cell Organelle Classroom Handouts Eukaryotic Kingdoms Eukaryotes include all the protists, plants, animals and fungi. Eukaryotes encompass a vast and diverse group of organisms, familiar kingdoms like plants and animals, along with protists and fungi. A defining characteristic of eukaryotic cells is the presence of a true nucleus, containing the genetic material (DNA), enclosed by
