Diffusion can be defined as the movement of molecules from a region of higher concentration to a region of lower concentration. Diffusion is an important process that occurs in living beings. Diffusion mostly occurs in liquids and gases because the molecules move randomly.
The factor that affects the rate of diffusion include
1. Permeability of the Cell Membrane: The rate of ...

Mitosis and meiosis are processes of cell division and reproduction in cellular organisms. Mitosis is simply the process of division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by a cell division. The daughter cells produced are genetically identical. The diploid cells also have the same number of chromosomes are the same as ...

All living organisms, both plants, and animals breathe through the process known as respiration. In plants, through the process of photosynthesis, carbon dioxide is used along with energy from sunlight, and oxygen is released as a byproduct. However, animals use this oxygen through the process of respiration. The process of respiration is divided into inspiration and expiration in ...

Spores can be defined as a reproductive cell that can develop into a new cell with fusion with another reproductive cell. Spores can be regarded as agents of asexual reproduction. Spores are bacteria, fungi, algae, and plants. They are produced by meiosis in the sporangium of a diploid sporophyte and are usually haploid and unicellular.
Gamete and spores are usually mistakenly for ...

The correct answer is Telophase II Telophase II is a phase in Meiosis II. It is the fourth and last phase of meiosis II. This phase comes after the anaphase II. In this stage, there is a complete separation of the 2 distinct nuclei to opposite sides of the poles of the cell.
Cytokinesis occurs and this leads to the division of the cytoplasm to produce 2 additional cells. Recombination ...

Prokaryotic cells are generally smaller than eukaryotic cells because they have less organelles in them. Prokaryotic cells are characterized by the absence of a nucleus or any other membrane bound organelles such as mitochondria, peroxisomes, Golgi apparatus, vacuoles, lysosomes and endoplasmic reticulum.
Eukaryotic cells contains at least one nucleus and many membrane organelles ...

The correct sequence of cell cycle is ïƒ G1 -> S -> G2 -> M The cell cycle is the process by which a cell increases in size in preparation for cell division. In this process. The cell copies its DNA, synthesizes and prepares for division, and then it divides.
Gap 1 (G1) Stages is when the DNA is copied. The synthesis (S) phase is the phase in which the copied DNA is replicated. It ...
