Difference between active and pasive Transport
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.06-Feb-2021

Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants

In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. ... All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.

The gynoecium (whether composed of a single carpel or multiple "fused" carpels) is typically made up of an o***y, style, and stigma as in the center of the flower.

Difference between Tap AdvantItious and Fiborus roots

Transportation is the process that transports water from roots to other parts of the plant while translocation is the process that conducts sucrose from leaves to other parts of the plant. Translocation is the process that transports synthesized food during photosynthesis from leaves to other plant parts

Difference between Unicellular and multicellular
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.

Nucleus
A nucleus is a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus

Function

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information..

Diference between meiosis and mitoisis

Ribosomes
are the organelles that help in protein synthesis. Protein is required for many cell activities such as damage repair and other chemical processes.

Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It includes ingestion, absorption, assimilation, biosynthesis, catabolism and excretion. The science that studies the physiological process of nutrition is called nutritional science.

Decomposer

An autotroph is a group of organisms capable of producing their own food by utilizing various substances like water, sunlight, air, and other chemicals. A heterotroph is a group of organisms that obtain their food from other organisms and are not capable of producing their own food

There are four types of tissues found in animals:
1epithelial tissue
2connective tissue
3muscle tissue,
4nervous tissue.

Plant tissue types
1dermal,
2vascular,
3 ground tissue

food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.

Mutualisms are defined as interactions between organisms of two different species, in which each organism benefits from the interaction in some way.

Animals
are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.

Ecisystem:
A complex network or interconnected system.
What is Ecosystem??
ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. ... Ecosystems can be very large or very small.

Producers: Photosynthesizing organisms. Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark.

Symbiosis (from Greek συμβίωσις, sumbíōsis, "living together", from σύν, sún, "together", and βίωσις, bíōsis, "living") is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic.

Bacteria' While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own

Bacteria are a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats

virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell, however, a virus can direct the cell machinery to produce more viruses. Most viruses have either RNA or DNA as their genetic material. The nucleic acid may be single- or double-stranded.

biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring. ... The term species can also be defined as the most basic category in the system of taxonomy.

Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivit

What is the difference between light and dark reaction?

The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.

Phagocytosis is the process by which a cell uses its plasma membrane to engulf a large particle, giving rise to an internal compartment called the phagosome. It is one type of endocytosis. A cell that performs phagocytosis is called a phagocyte.

Lysosomes are defined as sphere-shaped vesicles or sacs filled with hydrolytic enzymes that have the ability to break down almost all types of biomolecules. They essentially help clean up and recycle cellular debris and wastes

Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

The mitochondrion is a double membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms lack mitochondria. A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have reduced or transformed their mitochondria into other structures.

The cell wall is present only in plants and the cell membrane is present in every living organism including plants.

Plant cuticle is the outermost layer of plants, which covers leaves, fruits, flowers, and non-woody stems of higher plants. It protects plants against drought, extreme temperatures, UV radiation, chemical attack, mechanical injuries, and pathogen/pest infection.
