Jaringan parenkim spons atau jaringan bunga karang pada daun tumbuhan monokotil berfungsi untuk...
Correct Answer
B. Tempat terjadinya fotosintesis
Explanation
The correct answer is "tempat terjadinya fotosintesis" because the jaringan parenkim spons atau jaringan bunga karang (spongy parenchyma or coral flower tissue) in the leaves of monocot plants is responsible for carrying out photosynthesis. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen, using chlorophyll present in the parenchyma cells of the leaves. Therefore, this tissue functions as the site for photosynthesis in monocot leaves.

Skelerenkima adalah jaringan yang memberikan dukungan dan kekuatan pada tumbuhan, sedangkan meristematis bertanggung jawab untuk pertumbuhan dan perkembangan tumbuhan.
11.
Manakah yang bukan merupakan fungsi jaringan parenkim
Correct Answer
C. Alat untuk menyokong kekuatan organ tumbuhan
Explanation
The correct answer is "Alat untuk menyokong kekuatan organ tumbuhan". This is because the other options mentioned are all functions of parenchyma tissue. Parenchyma tissue is responsible for photosynthesis as it contains chloroplasts and is the main site of food storage in plants. It also helps in storing excess water. However, supporting the strength of plant organs is not a function of parenchyma tissue.

Penampang melintang akar monokotil berbeda dengan penampang melintang batangnya : Perbedaan itu terletak pada pernyataan berikut, kecuali ...
Correct Answer
B. Bentuk kambium
Explanation
The difference between the transverse section of a monocot root and stem lies in the presence of cambium. The transverse section of a monocot root does not have cambium, while the transverse section of a monocot stem does have cambium. The presence of pericycle, endodermis, and the arrangement of xylem and phloem may vary between the transverse section of a monocot root and stem, but the absence or presence of cambium is the key difference.
