Karyokinesis:
Karyokinesis is the biological process involving the division of a cell’s nucleus during mitosis or meiosis.
It is divided into four stages –prophase, metaphase, anaphase, and telophase.

The cellular components are called the Cell Organelles. These cell organelles are membrane-bound, present within the cells and are distinct in their structures and functions. They coordinate with their functions efficiently for the normal functioning of the cell. Few of them functions providing shape and support, whereas some are involved in the locomotion and reproduction of a cell. There are various organelles present within the cell and are classified into three categories based on the presence or absence of membrane.
Organelles without membrane: The Cell wall, Ribosomes, and Cytoskeleton are membrane-bound cell organelles. They are present both in prokaryotic cell and the eukaryotic cell.
Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell.
Double membrane-bound organelles: Mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

The taxonomic hierarchy is a systematic framework in classification in which taxonomic groups are arranged in definite order, from higher to lower categories. Each category is considered as a taxonomic unit and represents a Taxon.
Classification of Mango
Kingdom - Plantae
Division - Angiospermae
Class -Dicotyledonae
Order - Sapindales
Family - Anacardiaceae
Genus - Mangifera
Species - indica

In biology, a family is a taxonomic rank, or a taxon at that rank. Each family contains one or more genera. The next important rank is that of order. Usually, the name of the family ends with a "idae" for animals, and "aceae" for plants. Family is, in turn, more specific. Some families in the order Carnivora, for example, are Canidae (dogs, wolves, foxes), Felidae (cats), Mephitidae (skunks), and Ursidae (bears). There are 12 total families in the order Carnivora.

The scientific naming of an organism is called nomenclature. The system of scientific naming or nomenclature we use today was introduced by Carolus Linnaeus in the eighteenth century. In Binomial nomenclature, the first name is the generic name beginning with a capital letter whereas the second name is the species name which begins with a small letter. Example – <i>Homo</i> <i>sapiens</i> where <i>Homo</i> is a genus name and <i>sapiens</i> is a species name.
Certain conventions are followed while writing the scientific names:
1. The name of the genus begins with a capital letter.
2. The name of the species begins with a small letter.
3. When printed, the scientific name is given in italics.
4. When written by hand, the genus name and the species name have to be underlined separately.

• Euglenoids (such as <i>Euglena</i>) are unicellular protists commonly found in fresh water.
• Instead of the cell wall, a protein-rich cell membrane known as pellicle is present.
• They bear two flagella on the anterior end of the body.
• A small light sensitive eye spot is present.
• They contain photosynthetic pigments such as chlorophyll and can thus prepare their own food. However, in the absence of light, they behave similarly to heterotrophs by capturing other small aquatic organisms.
• They have both plant and animal-like features, which makes them difficult to classify and hence they are called as connecting link between plants and animals.

The cells usually have the same composition and the are made of similar molecules. All the molecules together in a particular fashion build up different cell organelle with specific functions. The constituents remain the same but the outcome or final product, function and purpose changes. Hence, properties of the cell organelles are not always found in the constituents

Taxonomy is a science that deals with naming, describing and classification of all living organisms including plants. Classification is based on behavioral, genetic and biochemical variations. Characterization, identification, and classification are the processes of taxonomy.Organisms are classified into similar categories namely kingdom, phylum, class, order, family, genus and species.

'Diatomaceous earth' is the accumulation of large deposits of diatoms that forms a siliceous covering extending for several 100 m formed in billions of years. The material obtained from these deposits is used in polishing and filtration of oils and syrups.

Ctenophores are organisms that show biradial symmetry. Biradial symmetry is basically a mixture of bilateral and radial symmetry. In this type of symmetry, the body components are arranged with similar parts on either side of the central axis, and each of the four sides of the body is identical to the opposite side but it is different from the adjacent side.
So, the correct answer is 'Ctenophora'.

Mesosomes are essential infoldings of the cell membrane, a unique characteristic of prokaryotic cells.
Gaurav Seth 4 years, 2 months ago
Mesosome is a convoluted membranous structure formed in a prokaryotic cell by the invagination of the plasma membrane. Its functions are as follows:
(1) These extensions help in the synthesis of the cell wall and replication of DNA. They also help in the equal distribution of chromosomes into the daughter cells.
(2) It also increases the surface area of the plasma membrane to carry out various enzymatic activities.
(3) It helps in secretion processes as well as in bacterial respiration.

- Primary and Secondary Growth: The mitotic divisions in meristematic cells at the root and shoot apex hikes the length of the plant. This is called as Primary Growth while Secondary meristem which results in an increased diameter of the plant known as Secondary Growth.
- Vegetative Growth: The growth in plants before flowering is known as vegetative growth and includes the formation of leaves, branches, and stems.
- Reproductive Growth: In this stage, the plants begin to flower which is a reproductive member of the plant.
