Microbiology: a science that studies microorganisms What is Microbiology - definition Microbiology is a science, a branch of biology, that studies microorganisms, which are very small living beings (viewed only with the aid of microscopes) and popularly known as microbes. Microbial Genetics - Medical Microbiology - Clinical Microbiology - Microbial Physiology - Veterinary Microbiology - Industrial Microbiology - Environmental Microbiology - Food Microbiology - Space Microbiology - Evolutionary Microbiology - Aeromicrobiology (studies of microorganisms carried by air).

Glucose Molecule Lipogenesis When we eat carbohydrates, they are turned into glucose and it enters the bloodstream. When the concentration of glucose deposited in the blood exceeds its maximum limit, its excess is removed by the liver, and the liver stores it inside as glycogen.
Plant Reproduction: Pollination is One of the Main Processes Introduction Every organism needs to reproduce, otherwise many species of organisms would disappear and life on Earth would be seriously compromised. Reproductive Process On our planet there is a great variety of living organisms, these different species of life are dependent on each other not only to ensure their continuity, but also the balance of the ecosystem.
Aquifer parenchyma: function of storing water What it is (definition) Parenchyma is a permanent (adult) plant tissue that originates mainly from meristems (tissue composed of fast growing cells). Main general characteristics of plant parenchyma: - They are found in all plant organs; - They have thin, thin and flexible primary walls; - have vacuoles; - Presence of schizogenic spaces (spaces between plant cells); - They present varied formats; - Parenchymal cells are not specialized.
Large intestine: important functions in the human body. Introduction The large intestine is one of several organs that make up the digestive system, and is located in the final portion of the tract. It performs several functions, and has anatomical differences when compared to the other members of the set.
Sclerenchyma: Supporting Plant Tissue (larger image) What are Collenchyma and Sclerenchyma are plant tissues that are primarily responsible for supporting the plants. Main features of the collenchyma - The collenchyma is composed of living cells. - The cells have a thick cell wall consisting of cellulose, pectin and other types of substances.
Xerophyte plants: adaptation to semiarid and desert climates What they are (definition) Xerophytes are plants adapted to live in regions of semiarid and desert (arid) climates. Cacti are the best known xerophyte plants. However, there are several non-cactus species that belong to the xerophytes.
Adipose Tissue: Cells That Have a Lot of Fat What is Adipose Tissue Also known as fat tissue, adipose tissue is a tissue in the human body whose cells contain oils and fats. This tissue is located mainly below the skin, ie in the subcutaneous region. We can also find adipose tissue involving some organs such as the heart and kidneys.
Bibliographic indication for the study of Plant Biology (Botany) Bibliography (indication of books on Botany): Plant Biology Author: Eichhorn, Susan E. & others Publisher: Gunabara Introduction to Plant Biology Author: Oliveira, EUrico Cabral de Publisher: Edusp Plant Biology - school practice manual Author: Cunha, Gladis F.
Victoria regia: common aquatic plant in the Amazon What they are (definition) Aquatic plants, also known as hydrophilic or hydrophyte plants, are those that have the ability to live in aquatic environments or with a high amount of moisture. Some species live fully submerged in water, while others keep only their roots and stems under water.
Leaves with thorns: protection for the plant Introduction There are several types of leaves in nature's vegetables, each of which plays an important role for the plant. These sheets are classified according to their function. Cotyledons These are embryonic leaves of seeds and play an important role in the process of embryo nutrition.
Microtubule: various cellular functions What they are (definition) Microtubules are structures (filaments) present in the cells of eukaryotes. They are formed by the polymerization process of two globular proteins (alpha and beta tubulin) and a dimer. They are important because they are involved in various processes performed by cells.
Prokaryotic Cell: Simple Cell Organization What They Are - Definition Prokaryotic cells, also known as prokaryotic cells, are those that have a very simple organization. In them, the cell nucleus material is scattered throughout the cytoplasm. Examples We can cite as examples of beings that are formed by prokaryotic cells: bacteria and cyanobacteria.
Cytoskeleton: Structure with Various Functions in the Cell What It Is and Composition The cytoskeleton is a cellular structure, a kind of network, composed of a set of three different types of protein filaments. They are: microtubules, intermediate filaments and microfilaments. Cytoskeleton composition The cytoskeleton is basically made up of two proteins: actin and tubulin.
Alamanda: Toxic Plant Example What they are and care Toxic plants are those that produce toxins that can cause health problems in humans and domestic animals. Depending on the person and the degree of toxicity of the plant, reactions can range from a simple allergy to death. These toxic substances can be present in all parts of the plant or only in parts of it (leaves, fruits, seeds, roots).
Active Transport in a Cell What it is - Definition Active transport is the energy used by cells to transport substances across their plasma membrane. Active transport process and main features. This process involves a carrier protein called a pump, which performs transport by carrying a substance across the cell membrane from a lower concentration area to a higher concentration area.
Mitochondria: responsible for cellular respiration Introduction All cell activity requires energy, and this is obtained through mitochondria. This organelle is responsible for producing energy through a process known as cellular respiration. How It Happens: Summary of Key Characteristics of Cellular Respiration To get energy, the cell must necessarily have glucose.
Exocytosis: An Important Biological Process That Occurs in Cells Introduction (What They Are) Endocytosis and exocytosis are procedures through which elements (molecules, substances, living things) cross the cell membrane. In the case of endocytosis, the element goes from the outside into the cell. Already in exocytosis, it is transferred from the cellular interior to the exterior.
Entamoeba histolytica: Cause of amoebiasis Cause of the disease The cause of amoebiasis is caused by protozoan infection (Entamoeba histolytica), which can benefit from its host without causing benefit or harm, or act invasively. In this case, the disease may manifest inside or outside the intestines.
Hand of a person with arthritis Introduction Arthritis is an inflammatory process that manifests itself in the joints, resulting in some signs and symptoms (joint swelling, stiffness, pain) resulting from joint damage. Knowing Arthritis Causes and Classification (Types) Arthritis has different triggering factors (causes).
