Diversity of cells Eukarya – Plants, animals, fungi, and protists Bacteria – Single-celled microorganisms Archaea – Single-celled microorganisms The four eukaryotic kingdoms are fungi, protists, Animalia, and Plantae. Kingdom Plantae includes plants that manufacture their own food. Kingdom Animalia is for animals that ingest and digest food from external sources rather than making their own. … Read more
Cells and Viruses In 1676, van Leeuwenhoek used his microscopes to look into a drop of lake water and discovered small tiny creatures living in it. He laid the foundations of cell biology and microbiology A Cell is defined as the membrane-bound structure that forms the basic unit of life. The cytoplasm of the cell … Read more
Viruses: Are microscopic molecules containing proteins and nucleic acids Attack cells and replicate within them They are not classified as cells but as particles They cannot reproduce on their own nor live on their own For the virus to recognize host cells, it uses the capsid which has a specific structure to unlock a receptor … Read more
Atoms that makeup living things Organisms are made of cells. Cells are made of molecules. Molecules are made of atoms. Atoms are made of subatomic particles The six elements that make up 99% of all living matter are carbon, hydrogen, nitrogen, phosphorous, oxygen, and sulfur. A tissue is a group of similar cells that perform … Read more
Structure of Carbohydrates Carbohydrates are molecules made up of hydrogen, oxygen, and carbon There are two main types of carbohydrates: Monosaccharides– known as simple sugars eg glucose Polysaccharides- they are complex carbohydrates Monosaccharides This is single sugars They have a generic formula; CH2O They are colorless and crystalline solids which are water-soluble and insoluble in … Read more
Q1 Genotype is the observable features of an organism True/False Answer False Remember in our lesson on genotype and phenotype, we discovered that the genotype is what we have within our DNA, and is not observable or physical. Rather, the physical features we see like skin and hair color are what we describe as phenotype. … Read more
Introduction Most cellular jobs are performed by proteins Proteins interact with other molecules in specific ways to perform cellular functions Levels of protein structure Proteins are amino acid polymers The amino acid polymer is called a polypeptide Once polypeptides are functional after being folded, the polypeptides are called proteins Some proteins are generated by folding … Read more

How cells communicate Cells live in environments with numerous signals. Cels take up materials from the environments across plasma membranes. Transport across membranes Two factors determine whether materials can cross the plasma membrane. Size: Small molecules can cross the plasma membrane faster than larger molecules. Attraction to water: hydrophobic molecules can easily cross the plasma … Read more
