Variety of Organisms & Classification of Living Things
Solution
All living organism
A
Photosynthesize
B
Respire
C
Move
D
Feed
E
Transpire
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
All living organisms, from bacteria to humans, carry out cellular respiration, which is the process of converting glucose into energy (ATP) using oxygen.
The other options are not universal characteristics of all living organisms:
A. Photosynthesize: Only plants, algae, and some bacteria can photosynthesize, converting light energy into chemical energy.
C. Move: Not all living organisms can move, such as plants, fungi, and some microorganisms.
D. Feed: While many organisms feed on other organisms or organic matter, some, like plants and algae, produce their own food through photosynthesis.
E. Transpire: Transpiration is the process of water evaporation through leaves, which is specific to plants and some algae.
Respiration, however, is a fundamental process that occurs in all living cells, making it the correct answer.

Solution
Which of these tissue serves the function of support and water conduction
A
Parenchyma
B
Collenchymas
C
Sclerenchyma
D
Xylem
E
Phloem
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Xylem tissue in plants serves both as a conduit for water and dissolved minerals and provides structural support. It is a specialized vascular tissue that transports water and dissolved minerals from the roots to the rest of the plant, including stems and leaves.
Xylem tissue, particularly the wood, provides mechanical support and strength to the plant, helping it stand upright and resist deformation. Also, it consists of specialized cells, including tracheids and vessel elements, which are responsible for water conduction.

medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
- The Hereditary characters of an organism are determined by genes.
- However, Chromosomes are dark staining structures in a cell's nucleus on which the organism's genes (DNA molecules) are arranged.
- I.e Chromosomes are the carriers of genes.
- And these genes are located on the Loci of the Chromosome.

A
Grows on moist dead organic matter
B
Is a plant
C
Has cellulose cell-wall
D
Reproduce asexually by producing a spore
E
Has no chlorophyll
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
While technically both statements are false, Option C is often the primary intended answer in many academic contexts because it highlights a defining biochemical difference between fungi and plants.
Kingdom Fungi: Mucor and Rhizopus are fungi, not plants. They belong to the Kingdom Fungi, specifically the class Zygomycetes.
Cell Wall Composition: Unlike plants, which have cell walls made of cellulose, the cell walls of Mucor and Rhizopus are primarily composed of chitin.
