Perbedaan sel prokariotik dan sel eukariotik terutama terletak pada ….
Correct Answer
A. Membran inti sel
Explanation
The correct answer is "membran inti sel." The main difference between prokaryotic and eukaryotic cells is the presence of a nucleus. Prokaryotic cells do not have a membrane-bound nucleus, while eukaryotic cells do. The nucleus in eukaryotic cells contains the cell's DNA and is responsible for controlling all cellular activities. Therefore, the presence or absence of a membrane-bound nucleus is the key difference between prokaryotic and eukaryotic cells.
2.
Materi genetik sebuah sel eukariotik tersimpan di ….
Correct Answer
B. Nukleus
Explanation
The genetic material in a eukaryotic cell is stored in the nucleus. The nucleus contains the cell's DNA, which carries the instructions for the cell's functions and characteristics. This genetic material is organized into chromosomes and is protected within the nucleus. The other organelles listed, such as the Golgi apparatus, chloroplasts, ribosomes, and mitochondria, have different functions within the cell but do not store the genetic material.

Bagian berikut dimiliki oleh sel prokariot dan eukariot adalah …
Correct Answer(s)
A. Ribosom
D. Membran sel
Explanation
Both prokaryotic and eukaryotic cells have ribosomes, which are responsible for protein synthesis. Additionally, both types of cells have a cell membrane, which regulates the movement of substances in and out of the cell. Therefore, ribosomes and cell membranes are common features shared by prokaryotic and eukaryotic cells.

Amoeba mendapatkan mangsa dengan cara pinositosis
Correct Answer
A. True
Explanation
Amoeba mendapatkan mangsa dengan cara pinositosis. Pinositosis adalah proses di mana amoeba menelan mangsa dengan membentuk vesikel yang mengandung mangsa tersebut. Dalam proses ini, amoeba mengeluarkan pseudopodia (proyeksi bergerak) yang mengelilingi mangsa dan membentuk vesikel yang kemudian masuk ke dalam sel amoeba. Proses pinositosis ini memungkinkan amoeba untuk mendapatkan nutrisi dari mangsa yang ditelan.

Organel yang memilih, memodifikasi, dan membungkus protein yang baru disintesis adalah nukleus
Correct Answer
B. False
Explanation
The organelle that selects, modifies, and packages newly synthesized proteins is the Golgi apparatus, not the nucleus. The nucleus is responsible for housing the cell's genetic material and controlling cellular activities through gene expression. The Golgi apparatus, on the other hand, receives proteins from the endoplasmic reticulum, modifies them, and packages them into vesicles for transport to their final destinations within the cell or for secretion outside the cell. Therefore, the correct answer is false.

Di bawah ini yang merupakan ciri dari sel tumbuhan adalah....
Correct Answer(s)
B. Memiliki dinding sel
D. Memilki plastida
E. Tidak memiliki sentriol
Explanation
The correct answer is "Memiliki dinding sel, Memiliki plastida, Tidak memiliki sentriol". This is because plant cells are characterized by having a cell wall, which provides structural support and protection. They also have plastids, such as chloroplasts, which are responsible for photosynthesis. Unlike animal cells, plant cells do not have centrioles, which are involved in cell division.

Saluran yang berlipat-lipat dan tertutup membran dengan ribosom pada permukaan membrannya disebut ….
Correct Answer
C. RE kasar
Explanation
The correct answer is "RE kasar" (rough endoplasmic reticulum). The rough endoplasmic reticulum is a network of folded and membrane-bound channels that are studded with ribosomes on its surface. These ribosomes are responsible for protein synthesis. The rough endoplasmic reticulum plays a crucial role in the production, folding, and transport of proteins within the cell.
