Safety in Life SciencesSafety is one of the most important aspects of working in the life sciences. Whether you're conducting an experiment in the lab, studying plants and animals outdoors, or handling biological materials, following safety rules helps protect you, your classmates, and the environment. Adhering to these rules allows us to conduct science safely without accidents, contamination, or health risks.Science and Engineering Practices (SEP - Planning and Carrying Out...

Fields in the Life SciencesLife sciences focus on studying living organisms and their interactions with the environment. Scientists in this field explore everything from microscopic cells to vast ecosystems to understand how life functions, adapts, and evolves.Botany- The study of plants, including their growth, structure, and environmental interactions. Scientists in this field explore how plants produce food, respond to environmental changes, and support other living organisms.Zoology- The...

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

Overview

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...
