Question:
Algae have cell wall made up of
Algae have cell wall made up of
Updated On: Jun 23, 2024
- cellulose, galactans and mannans
- hemicellulose, pectins and proteins
- pectins, cellulose and proteins
- cellulose, hemicellulose and pectins.
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
majority of algae (eukaryotes) possess a definite cell wall containing cellulose and other carbohydrates. In algal cell wall, different chemical components are present which vary widely among different groups (e.g., xylan, mannan, galactan, alginic acid, silica, agar, pectin, carrageen in, etc.). Cell wall of blue-green algae is made up of micro-peptides (proteins). This micro-peptide is not found in eukaryotic algae.

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 After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm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

Concepts Used:
Plant Kingdom
The Plant Kingdom comprises all the plants that have some shared characteristics. These are bacteria (prokaryotes), photosynthetic plants, fungi, and several non-photosynthetic plants.

Several features of Kingdom Plantae are as follows:
- They are stationary. They are static and usually remain in one place only.
- They have branches that expanded and green leaves due to the presence of chlorophyll.
- They are an autotrophic mode of nutrition that simply means they prepare their food with the help of water, sunlight and carbon dioxide. It is further known as self-nutrition.
- They indulge in photosynthesis during the day and therefore more carbon dioxide is needed during the day and at night it is released.
- They secure their food in the form of starch-like algae.
- They have an inelastic wall around their cell known as a cell wall comprised of cellulose.
- There is an absence of the nervous system and excretory system.
- Reproduction is entirely dependent on air, insects and water. Asexual and vegetative method of reproduction is noticed or detected.
- The non-photosynthetic plants acquire their food through parasitism, i.e through their host like Indian pipe.
