<h2 class="wp-block-heading" id="h-question-3-fungi-grouping">Question 3: Fungi Grouping</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>Which of the following is <strong>not correct</strong> about the grouping of fungi?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Options:</strong><br>A. They form asexual spores<br>B. Oomycetes form asexual spores<br>C. Basidiomycetes form sexual spores<br>D. Zygomycetes form asexual spores</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> A</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>A is incorrect because not <strong>all</strong> fungal groups form <strong>only</strong> asexual spores — many also form sexual spores.</p>

<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>Photosynthesis takes place in which part of the leaf?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Options:</strong><br>A. Stomata<br>B. Chloroplast<br>C. Mesophyll<br>D. Vascular bundle</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> B. Chloroplast</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->

<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>What is the byproduct of the light-dependent reaction of photosynthesis?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Options:</strong><br>A. Water (H₂O)<br>B. Carbon dioxide (CO₂)<br>C. Oxygen (O₂)<br>D. ATP</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> C. Oxygen</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Oxygen is released during the light-dependent stage of photosynthesis when water is split.</p>

<h2 class="wp-block-heading" id="h-question-6-internal-change-before-germination">Question 6: Internal Change Before Germination</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p><strong>Question:</strong><br>What is the internal change that a seed undergoes before germination?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Options:</strong><br>A. After-ripening<br>B. Dormancy<br>C. Sprouting<br>D. Fertilization</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p> <strong>Correct Answer:</strong> B. Dormancy</p>
<!-- /wp:paragraph -->

<p><strong>Question:</strong><br>Which of the following is <strong>not</strong> a correct importance of mosses?</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Options:</strong><br>A. They initiate soil erosion<br>B. They reduce soil quality<br>C. They prevent erosion<br>D. They aid soil fertility</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p><strong>Correct Answer:</strong> A</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Mosses do <strong>not initiate erosion</strong>; in fact, they help <strong>prevent erosion</strong> and improve soil structure.</p>
