Metamorphosis: When the young one does not resemble the adult, such a young one is known as a larva or nymph, it is known as indirect development. The change from nymph or larva to adult is called metamorphosis. The transformation of a larva into an adult is characterized by a series of sudden morphological, physiological, and behavioral changes.
Butterflies, flies, bees and beetles have a 4 stage life cycle that includes egg, larva, pupa and imago. There are three kinds of metamorphosis: ametabolism, hemimetabolism and holometabolism. All the three kinds can be seen in insects. Read this article to get an insight on types of metamorphosis.
It is an insect development pattern characterised by morphologically diverse egg, larva, pupal, and adult phases. Incomplete metamorphosis comprised of a nymph resembling a miniature adult. Complete metamorphosis comprised of a very active, ferociously eating larva and an inert pupa. Three phases comprise incomplete metamorphosis: egg, nymph ...
Hemimetabolous. It refers to insects that show incomplete metamorphosis or hemimetabolism. Their life cycle includes egg, nymph, imago or adult. The pupal stage is absent. The nymphs or naiads undergo gradual metamorphism and turn into adults. There are many hemimetabolous insects like grasshoppers, praying mantises, mayflies, damselflies, etc.
Metamorphism in Frogs. Metamorphism is a hormonal effect. Metamorphism in frogs is controlled by the hormones called thyroxine, and it is produced by the gland called the thyroid. For the production of thyroxine, the thyroid gland needs iodine. Frogs need to live in water bodies where sufficient iodine is present for thyroxine production.
Metamorphosis: Metamorphosis in insects can be defined as the change in physical and structural form from the larval stage to the adult stage. The hormone ecdysone is responsible for metamorphosis in insects such as caterpillars. This hormone helps in the molting or shedding of old body parts for the formation of new physical forms.
Complete Metamorphosis. As stated before, fleas go through complete metamorphism, which means it has four stages in its life cycle, namely: Egg stage. Larvae stage. Pupa stage. Adult stage. Typically, fleas go through these stages in 14 to 140 days depending on the weather conditions and other environmental factors.
In oviparous animals, fertilization takes place internally but embryo development takes place externally. The eggs of birds such as hen and duck carry immature embryo in them. The hard shells of eggs protect them from damage. Once the fetus is matured, the egg hatches. The trait of egg-laying animals is known as oviparity.
Metamorphosis is a rapid and complete transformation from an immature larval life to a sexually adult form involving morphology, function, and habitat changes. The life cycle of a butterfly: The butterfly lays its egg on the leaves of the plants. The new born that comes out of the egg is called a larva or caterpillar.
Jul 12, 2022 · Reproduction is a biological process by which an organism reproduces an offspring that is biologically similar to the organism. Reproduction enables and ensures the continuity of species, generation after generation. It is the main feature of life on earth. Let us have a detailed overview of reproduction, its types and the modes of reproduction ...
