Auxospores and hormocysts are formed, respectively, by :
- several diatoms and a few cyanobacteria
- several cyanobacteria and several diatoms
- some diatoms and several cyanobacteria
- some cyanobacteria and many diatoms
The Correct Option is A
Solution and Explanation
Auxospores are formed by several diatoms, and hormocysts are formed by several cyanobacteria.
So, the correct option is (C): several diatoms and a few cyanobacteria

Questions Asked in NEET exam
- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. - A wire of resistance \(R\) is cut into 8 equal pieces. From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

Concepts Used:
Algae
An Algae is a term mentioning a group of photosynthetic eukaryotic organisms. It has chlorophyll and nucleus but no root, stem, leaves and many features like normal land plants. Algae is both unicellular (e.g. Euglenophyta) and multicellular (e.g. seaweeds). Algae do photosynthesis and help in oxygen production
Algae can live in various habitats like moist rocks, soils, water bodies (both freshwater and marine) and in some animals (e.g. Sloth). Unicellular Algae belong to the Protista Kingdom and Multicellular algae belong to the Plantae Kingdom, but formerly all algae are categorized under kingdom Plantae for their photosynthetic nature.
