The process by which atmospheric CO₂ is fixed into organic compounds by plants is: MCQ with Answer and Explanation

Explanation:
Late blight of potato is caused by the oomycete Phytophthora infestans (historically considered a fungus). It caused the Irish Potato Famine. Tobacco mosaic is viral, citrus canker is bacterial (Xanthomonas), crown gall is bacterial (Agrobacterium tumefaciens). Fungal plant diseases also include rust, smut, and powdery mildew. Oomycetes are now classified under Chromista but traditionally studied in mycology.

The larynx, also called the voice box, contains vocal cords that vibrate as air passes, producing sound. It is located at the top of the trachea. The trachea (windpipe) conducts air; pharynx is the common passage for food and air; bronchi lead to lungs. The larynx is cartilaginous, and in males, the thyroid cartilage forms the Adam's apple.

Explanation:
Centrioles are cylindrical structures composed of nine evenly spaced peripheral fibrils of tubulin, arranged in a 9+0 pattern. Each fibril is a triplet of microtubules. The central part is non-branched and lacks microtubules. Centrioles are involved in forming the spindle apparatus in animal cells and basal bodies of cilia and flagella.
