1.
Which cell organelle is represented by arrow #1?
Correct Answer
B. Nucleus
Explanation
The cell organelle represented by arrow #1 is the nucleus. The nucleus is a membrane-bound organelle that contains the cell's genetic material, DNA. It is often referred to as the control center of the cell as it regulates gene expression and controls the cell's activities. The nucleus is usually located near the center of the cell and is surrounded by a double membrane called the nuclear envelope.
2.
Which organelle is represented by arrow #2?
Correct Answer
D. Mitochondrion
Explanation
The mitochondrion is a specialized organelle found in animal cells that serves as the "powerhouse" of the cell. Its primary function is to generate energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration. Mitochondria are often referred to as the cell's "energy factories."
3.
Which organelle is represented by arrow #3?
Correct Answer
A. Golgi Apparatus
Explanation
Arrow #3 represents the Golgi Apparatus. The Golgi Apparatus is responsible for modifying, sorting, and packaging proteins and lipids for transport to their final destinations. It consists of a series of flattened sacs called cisternae. The Golgi Apparatus is involved in the secretion of substances such as enzymes and hormones, as well as the formation of lysosomes.
4.
Which organelle is represented by arrow #4?
Correct Answer
B. Endoplasmic Reticulum
Explanation
The correct answer is Endoplasmic Reticulum because arrow #4 is pointing towards a network of membranes that is responsible for protein synthesis, lipid metabolism, and detoxification. This organelle is commonly found in eukaryotic cells and can be further classified into rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER) based on the presence or absence of ribosomes on its surface.
5.
Which organelle is represented by arrow #5?
Correct Answer
D. Cytoplasm
Explanation
Answer D is correct.
6.
What is represented by arrow #6?
Correct Answer
A. Plasma Membrane
Explanation
The plasma membrane of an animal cell is a dynamic structure that controls the flow of substances, protects the cell, facilitates communication, and is crucial for the cell's overall function and survival.
7.
Which of these is an animal cell?
Correct Answer
B. Option 2
Explanation
A and C both have cell walls and large vacuoles, which makes them plant cells. D has no nucleus which makes it a prokaryotic bacteria cell.
8.
What is this part?
Correct Answer
B. Endoplasmic Reticulum
Explanation
The correct answer is Endoplasmic Reticulum. The Endoplasmic Reticulum is an organelle found in eukaryotic cells that plays a key role in the synthesis, folding, and transport of proteins and lipids. It consists of a network of membrane-bound tubules and sacs, and is connected to the nuclear envelope. The Endoplasmic Reticulum is involved in various cellular processes, including protein synthesis, lipid metabolism, and calcium storage. It can be further divided into rough and smooth regions, with the rough Endoplasmic Reticulum having ribosomes attached to its surface and playing a major role in protein synthesis.
9.
What is the part in the picture?
Correct Answer
C. Lysosome
Explanation
The correct answer is Lysosome. A lysosome is a membrane-bound organelle found in animal cells. It contains digestive enzymes that break down waste materials and cellular debris. In the picture, the part shown resembles a spherical structure with a membrane, indicating that it is a lysosome. The other options, such as cytoplasm, ribosome, and microtubule, do not match the visual characteristics of the part in the picture.
10.
What is the part in the picture?
Correct Answer
B. Ribosome
Explanation
The correct answer is Ribosome. Ribosomes are found in cells that are responsible for protein synthesis. It is typically composed of two subunits and can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum. In the given picture, the part shown resembles the structure of a ribosome, with its characteristic small size and distinct shape.
