Match List-I with List-II.
{List-I} & {List-II}
A. Fusion of protoplasms between gametes & I. Meiosis
B. Fusion of two nuclei & II. Plasmogamy
C. Generation of haploid spores & III. Karyogamy
Choose the correct answer from the options given below :
View Solution
Step 1: Understanding the Question:
The question requires matching key stages of the sexual cycle in fungi (and general eukaryotic sexual reproduction) with their scientific terms.
Step 2: Detailed Explanation:
The sexual cycle in fungi typically involves three sequential steps:
A. Plasmogamy: The first step is the fusion of the cytoplasm (protoplasms) of two motile or non-motile gametes or mating types. (\(A \rightarrow II\))
B. Karyogamy: Following plasmogamy, the two haploid nuclei within the fused cell combine to form a single diploid nucleus (zygote). "Karyo" means nucleus. (\(B \rightarrow III\))
C. Meiosis: The diploid zygote undergoes reductional division (meiosis) to generate haploid sexual spores, resetting the chromosomal count. (\(C \rightarrow I\))
Matching results: A-II, B-III, C-I.
Step 3: Final Answer:
The correct matching is A-II, B-III, C-I.
Quick Tip: The prefixes are a dead giveaway: Plasmo- = plasma/cytoplasm; Karyo- = nucleus. Knowing just one root word can often solve the entire matching question!

B. Cisternae & II. Infoldings in mitochondria
C. Thylakoids & III. Cell membrane
D. Phospholipid & IV. Disc shaped sacs in the Golgi apparatus
Choose the correct answer from the options given below :
View Solution
Step 1: Understanding the Question:
We need to correctly match cellular structures to their definitions or locations.
Step 2: Detailed Explanation:
Let's pair each biological term with its correct description:
A. Cristae: These are the deep, finger-like infoldings of the inner membrane of mitochondria that increase surface area for ATP production. (\(A \rightarrow II\))
B. Cisternae: These are the stacked, flat, disc-shaped membranous sacs that constitute the Golgi apparatus and Endoplasmic Reticulum. (\(B \rightarrow IV\))
C. Thylakoids: These are the flattened, coin-like membrane sacs located in the stroma of the chloroplast, which contain chlorophyll for light reactions. (\(C \rightarrow I\))
D. Phospholipid: The fundamental structural lipid molecule that forms the lipid bilayer of the cell membrane. (\(D \rightarrow III\))
Matching results: A-II, B-IV, C-I, D-III.
Step 3: Final Answer:
The correct matching is A-II, B-IV, C-I, D-III.
Quick Tip: Do not confuse {Cristae} (inner folds of Mitochondria) with {Cisternae} (stacked sacs of the Golgi). This is one of the most frequently tested vocabulary mix-ups in cytology!

D. Glut-4 & IV. Lectin
Choose the correct answer from the options given below :
View Solution
Step 1: Understanding the Question:
We need to correctly match biological molecules/proteins from a standard biomolecules table with their primary physiological functions.
Step 2: Detailed Explanation:
Let's pair each molecule with its function:
A. Starch: A complex carbohydrate (polysaccharide) serving as the primary energy storage molecule in plants. (\(A \rightarrow II\))
B. Antibody: Specialized proteins (immunoglobulins) produced by the immune system to identify and neutralize foreign objects. They help fight infection. (\(B \rightarrow I\))
C. Concanavalin A: A carbohydrate-binding protein. Such proteins are classified as lectins. (\(C \rightarrow IV\))
D. GLUT-4: An insulin-regulated protein that facilitates glucose transport into cells, particularly in fat and muscle tissue. (\(D \rightarrow III\))
Matching results: A-II, B-I, C-IV, D-III.
Step 3: Final Answer:
The correct option is (3) A-II, B-I, C-IV, D-III.
Quick Tip: GLUT-4 stands for {GLU}cose {T}ransporter type 4. Even if you forget the others, knowing this abbreviation immediately solves part D.

Match the common morphological shapes of bacteria (List I) with their scientific taxonomic terminology (List II).
Step 2: Detailed Explanation:
Bacteria are grouped into four major categories based on their shape:
A. Spherical: Bacteria that are round or spherical are called Coccus (plural: Cocci). (\(A \rightarrow II\))
B. Rod: Bacteria that are rod-shaped are called Bacillus (plural: Bacilli). (\(B \rightarrow IV\))
C. Comma: Bacteria shaped like a comma are called Vibrio. (\(C \rightarrow I\))

View Solution
Step 1: Understanding the Question:
The question requires matching various taxonomic categories with their specific nomenclature based on the biological classification of the mango plant ({Mangifera indica).
Step 2: Detailed Explanation:
Let us classify the mango plant step-by-step:
A. Family: Mango belongs to the family Anacardiaceae. (\(A \rightarrow III\))
B. Genus: The genus name of mango is Mangifera. (\(B \rightarrow V\))
C. Class: Mango is a dicotyledonous plant, so its class is Dicotyledonae. (\(C \rightarrow II\))
D. Phylum / Division: As a flowering plant, its division is Angiospermae. (\(D \rightarrow IV\))
E. Order: Mango belongs to the order Sapindales. (\(E \rightarrow I\))
Combining these, the correct match sequence is A-III, B-V, C-II, D-IV, E-I.
Step 3: Final Answer:
The correct matching is option (A).
Quick Tip: Always memorize the complete classification table of common organisms given in the NCERT text (Mango, Wheat, Housefly, Human) as direct matching questions are frequently derived from it.

A. Marginal placentation & I. Argemone
B. Axile placentation & II. Tomato
C. Parietal placentation & III. Primrose
D. Free central placentation & IV. Pea
Choose the correct answer from the options given below :
View Solution
Step 1: Understanding the Question:
The question asks to match different types of placentation (the arrangement of ovules within the ovary) with the plant examples that exhibit them.
Step 2: Detailed Explanation:
Let's match each placentation type with its classic example:
A. Marginal placentation: The placenta forms a ridge along the ventral suture of the ovary, and ovules are borne on this ridge forming two rows. Example: Pea. (\(A \rightarrow IV\))
B. Axile placentation: The placenta is axial, and the ovules are attached to it in a multilocular ovary. Examples: China rose, Tomato, and lemon. (\(B \rightarrow II\))
C. Parietal placentation: Ovules develop on the inner wall of the ovary or on the peripheral part. Examples: Mustard and Argemone. (\(C \rightarrow I\))
D. Free central placentation: Ovules are borne on a central axis, and septa are absent. Examples: Dianthus and Primrose. (\(D \rightarrow III\))
Matching results: A-IV, B-II, C-I, D-III.
Step 3: Final Answer:
The correct matching is option (A).
Quick Tip: Placentation examples are high-yield questions. Memorize the key pairs: Marginal = Pea; Axile = Tomato, Lemon, China rose; Parietal = Mustard, Argemone; Free central = Dianthus, Primrose; Basal = Sunflower, Marigold.

Which of the following is not a prokaryote ?
Arrange the following elements in descending order of their contribution to percentage weight of the human body.
(a) Oxygen \hspace{1cm} (b) Carbon
(c) Hydrogen \hspace{0.7cm} (d) Nitrogen
Choose the correct answer from the options given below :
View Solution
Step 1: Understanding the Question:
We need to arrange four major chemical elements in the decreasing order of their percentage weight contribution to the human body.
Step 2: Detailed Explanation:
Based on the standard elemental analysis of the human body, the percentage weight of these elements is roughly:
1. Oxygen (O): ~65%
2. Carbon (C): ~18.5%
3. Hydrogen (H): ~9.5%
4. Nitrogen (N): ~3.3%
Descending order (highest to lowest) is Oxygen > Carbon > Hydrogen > Nitrogen.
This corresponds to the sequence (a), (b), (c), (d).
Step 3: Final Answer:
The correct descending sequence is (a), (b), (c), (d).
Quick Tip: Water makes up about 60-70% of the human body by weight, and since oxygen is much heavier than hydrogen (16:2 mass ratio in \(H_2O\)), Oxygen is overwhelmingly the most abundant element by mass in the body!
