Identify the correct statement for spirogyra, leishmania and hydra
Show Hint
Asexual reproduction methods:
- Spirogyra \(\Rightarrow\) Fragmentation
- Leishmania \(\Rightarrow\) Binary fission
- Hydra \(\Rightarrow\) Budding
Updated On: Feb 25, 2026
- they reproduce sexually.
- they are unicellular.
- they are multicellular.
- they reproduce asexually.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understand the organisms.
Step 2: Analyze each option.
- Spirogyra: A filamentous green algae found in freshwater. It is multicellular and reproduces both sexually (conjugation) and asexually (fragmentation).
- Leishmania: A unicellular protozoan parasite that causes leishmaniasis. It reproduces asexually by binary fission.
- Hydra: A multicellular freshwater organism belonging to phylum Cnidaria. It reproduces both sexually (during unfavorable conditions) and asexually (by budding).
Step 2: Analyze each option.
- (A) they reproduce sexually: Incorrect. While Spirogyra and Hydra can reproduce sexually, Leishmania reproduces only asexually.
- (B) they are unicellular: Incorrect. Spirogyra and Hydra are multicellular; only Leishmania is unicellular.
- (C) they are multicellular: Incorrect. Leishmania is unicellular, not multicellular.
- (D) they reproduce asexually: Correct. All three organisms can reproduce asexually: Spirogyra by fragmentation, Leishmania by binary fission, and Hydra by budding.

- Most of metals occur in combined state in form of ores. Carbonate ores are converted into oxides by calcination and sulphide ores by roasting. Oxides are reduced with suitable reducing agent like carbon to get free metal. Highly reactive metals like – Al, Mg are also used as reducing agents to obtain metal from their oxides. Most reactive metals are obtained by electrolytic reduction of their molten ores. Alloying is a very good method of improving the properties of a metal. We can get desired properties by this method. The electrical conductivity and melting point of an alloy is less than that of pure metals.

Lenses can form different types of images depending upon their focal length and position of object. A convex lens can create real, inverted or virtual, erect images, while a concave lens forms only virtual and diminished images. The focal length determines the power of lens. Convex lenses have positive focal length while concave lenses have negative focal length by convention. When lenses are placed together, their combined power is determined by the sum of their individual powers.
