1. What is cytoplasm?

Explanation

Cytoplasm is the jelly-like substance that fills the cell and is responsible for maintaining cell shape and contains various organelles. It is located outside the nucleus.

2. What is the main function of the nucleus in a cell?

Explanation

The nucleus in a cell is responsible for containing the majority of the cell's genetic material, which includes the DNA with instructions for protein production and acting as the control center for cellular activities. This is its primary function.

Submit
3. What is chromatin?

Explanation

Chromatin refers to the complex of DNA and proteins found in the nucleus of a cell. It is not protein bound to RNA, carbohydrates in the cell membrane, or lipids in the mitochondria.

Submit
4. What forms when a cell divides, where the chromatin condenses into threadlike structures that pass genetic information from one generation to the next?

Explanation

Chromosomes are the structures that carry genetic information and are formed by the condensation of chromatin during cell division. Ribosomes are involved in protein synthesis, mitochondria are the powerhouse of the cell, and endoplasmic reticulum is involved in protein and lipid synthesis.

Submit
5. What is the structure of the nuclear envelope?

Explanation

The nuclear envelope is comprised of two membranes with nuclear pores facilitating the movement of materials in and out of the nucleus, ensuring proper communication with the rest of the cell.

Submit
6. What is the function of the nucleolus in a cell?

Explanation

The nucleolus is a small dense region within the nucleus where ribosomes are assembled, not where DNA replication occurs, lipid synthesis happens, or protein degradation takes place.

Submit
7. What is the function of ribosomes?

Explanation

Ribosomes are the cellular structures responsible for protein synthesis by translating messenger RNA (mRNA) into proteins. They can be found in the cytoplasm and on the endoplasmic reticulum in cells.

Submit
8. What is the function of the endoplasmic reticulum?

Explanation

The endoplasmic reticulum is responsible for lipid assembly, protein synthesis, and material export, not ATP production, DNA storage/replication, or forming the cell membrane.

Submit
9. What is the main function of the Golgi Apparatus?

Explanation

The Golgi Apparatus is responsible for modifying, sorting, and packaging proteins and other materials, not for producing energy, regulating cell division, or synthesizing carbohydrates.

Submit
10. What is the primary function of lysosomes?

Explanation

Lysosomes are membrane-bound organelles filled with enzymes that break down macromolecules, such as lipids, carbohydrates, and proteins, into smaller molecules that can be used by the cell. They are not involved in storing water, energy generation through photosynthesis, or regulation of cell division and growth.

Submit
11. What are vacuoles?

Explanation

Vacuoles are not small structures that produce energy, instead they are sac-like structures responsible for storing various materials and regulating water in cells. They are not tube-like structures involved in cell division or green pigment responsible for photosynthesis.

Submit
12. What is the primary function of mitochondria?

Explanation

Mitochondria are known as the powerhouses of the cell due to their ability to convert chemical energy in food to compounds usable by the cell through a process called cellular respiration. This energy is stored in ATP molecules for various cellular functions.

Submit
13. What is the function of the cytoskeleton?

Explanation

The cytoskeleton is a network of protein filaments that help the cell maintain its shape and are involved in cell movement. It provides structural support for the cell and plays a crucial role in various cellular processes.

Submit
14. What are microfilaments?

Explanation

Microfilaments are thin, threadlike structures made of the protein actin that play a key role in maintaining cell shape, cell division, and cell movement.

Submit
15. What are microtubules?

Explanation

Microtubules are an essential component of the cell's cytoskeleton, providing structural support and facilitating processes such as cell division and intracellular transport. They are composed of tubulin protein subunits and play crucial roles in various cellular functions.

Submit
16. Hello.

Explanation

The correct response to 'Hello' is 'Hello'. The other options are informal greetings but do not directly match the question.
