Classification of Cell Organelles

Organelles without membrane: The cell wall, ribosomes, and cytoskeleton are non-membrane-bound cell organelles. They are present both in the prokaryotic cell and the eukaryotic cell.

Single membrane-bound organelles: Vacuole, lysosome, Golgi apparatus, and endoplasmic reticulum are single membrane-bound organelles present only in a eukaryotic cell.

Double membrane-bound organelles: Nucleus, mitochondria, and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

Let us learn more in detail about the different cell organelles in brief.

Unit 10: English Spelling and Phonology

Index:

• English Spelling
• Orthographic Codes in EFL (Rules)
• Sound-Grapheme Relationships: Vowels, Consonants, Silent Letters
• Teaching the Written Code
• Games and Tasks

1. English Spelling

Study of language from two perspectives:

• Diachronic: Study of language over time.
• Synchronic: Study over a specific period in history.

English is the result of the influence of different languages: French, Greek, Latin, Anglo-Saxon (Latin alphabet).

The Great Vowel Shift was a massive change affecting long vowels in the 15th-18th centuries.

Examples: 'enquiry' vs. 'inquiry', American English 'colour' vs. 'color'.

2. Orthographic Codes in EFL (Rules)

Requires good visual memory and the ability to associate forms and meanings.

Rules:

• Consonant

Living vs. Non-Living Things

Both living and non-living things are made up of matter. All living things share certain common characteristics. These characteristics can help us identify a mineral as a non-living thing and a butterfly as a living one.

Composition of Non-Living Things

Non-living things are made up of inorganic matter. The most abundant chemical elements include:

• Oxygen
• Silicon
• Aluminum
• Iron

Composition of Living Things

Living things are made up of chemical elements called bioelements. The most abundant are:

• Oxygen
• Nitrogen
• Phosphorus
• Sulfur

Key Characteristics of Life

Nutrition

Autotrophic Nutrition

Organisms with autotrophic nutrition capture energy from their environment and use it to transform inorganic substances, such as water, carbon dioxide,... Continue reading "Key Differences Between Living and Non-Living Things" »

Genetics Terminology

Basic Concepts

• Trait: An inheritable characteristic of an organism.
• Gene: A DNA segment containing information that controls a specific trait.
• Allele: A variant form of a gene, often arising from mutations, contributing to hereditary variations.
• Locus (pl. Loci): The specific location of a gene on a chromosome.

Zygosity

• Homozygous Organism: Possesses identical alleles for a given gene (e.g., AA or aa).
• Heterozygous Organism: Possesses different alleles for a given gene (e.g., Aa).

Allele Interactions

• Dominant Allele: An allele that expresses its phenotype regardless of the paired allele.
• Recessive Allele: An allele that expresses its phenotype only when paired with an identical allele.

Genetic Inheritance Patterns

• Dominance (Dominant

Nucleic Acid Structure and Function

• Nucleoside: A part of a nucleotide made up of one sugar (ribose or deoxyribose) and one nitrogenous base (pyrimidine or purine) joined together by N-glycosidic bonds.
• Nucleotide: Simple molecules that form large molecules called nucleic acids. It is formed by a nitrogenous base, sugar, and three phosphate groups.
• Chromatin: Bundles of DNA and proteins; the normal state of the genetic material during interphase.
• Chromosome: Structures formed by the condensation of chromatin that appear when the cell is about to divide.
• Centromere: A bond that joins two sister chromatids; it's where the microtubules are attached to the chromosome during the division process.
• Telomere: The end of the arms of a chromosome, which prevents
