The epidermal tissue system consists of the epidermis, stomata, and trichomes, which provide protection and regulate gas exchange. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
The generative ll divides (often before or during pollen tube growth) to produce two sperm lls; one of these fuses with the egg ll. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

In algae, asexual reproduction occurs by biflagellate, motile zoospores, which germinate to form new plants. This follows from NCERT principle where relation explains outcome clearly for students.

That points to B: PHOT2. Compared with the other options, PHOT2 is the one that correctly describes the Phototropin+All concept. The wrong ones are A) PHOT1; C) CRY1; D) ZTL. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

That points to D: All of the above. Compared with the other options, All of the above is the one that correctly describes the Phototropin+All concept. The wrong ones are A) Phototropism; B) Chloroplast movement; C) Stomatal opening. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

The right choice is C: Serine residues. In Phototropin+All, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Tyrosine residues; B) Histidine residues; D) Aspartate residues. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

Pick C: PHOT1. Thinking through Phototropin+All step by step rules out the lookalikes and leaves PHOT1. Skip these: A) PHOT2; B) CRY1; D) ZTL. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Pick C: Blue light. Thinking through Phototropin+All step by step rules out the lookalikes and leaves Blue light. Skip these: A) Red light; B) Far-red light; D) UV-B light. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

The right choice is C: High. In cryptochrome, that matches how the process or concept actually works — the other choices mix up related ideas or use the wrong mechanism. Skip these: A) Very low; B) Moderate; D) Absent. A quick check: if an option needs energy, pumps, or the opposite direction of movement, ask whether that really applies.

That points to B: Flavoproteins. Compared with the other options, Flavoproteins is the one that correctly describes the cryptochrome concept. The wrong ones are A) Glycoproteins; C) Lipoproteins; D) Metalloproteins. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Pick B: Chromoprotein. Thinking through PHYTOCHROME step by step rules out the lookalikes and leaves Chromoprotein. Skip these: A) Flavoprotein; C) Lipoprotein; D) Glycoprotein. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.

Pick C: Unsuccessful. Thinking through VERNALIZATION & FLOWERING step by step rules out the lookalikes and leaves Unsuccessful. Skip these: A) Highly successful; B) Partially successful; D) Conclusive. For hormones and genes, match the molecule or gene to its real role, not a neighboring pathway.
