Answer:
1. Mitosis c) The process of cell reproduction of human tissues that occurs when the cell divides into two identical cells
2. Nucleus a) The dense, active protoplasm found in the center of the cell
3. Cytoplasm b) The watery fluid that surrounds the nucleus of the cell and is needed for growth, reproduction, and self-repair
4. Cell membrane d) The part of the cell that encloses the protoplasm and permits soluble substances to enter and leave the cell
Explanation:
- Mitosis is the process that undergoes a cell to give two new identical cells. This is how our body makes or renovates tissues.
- The nucleus is the part of the cell that contains the DNA, which is necessary to synthesize the proteins that the cell and our body need. It is in the center of the cell and has a nuclear membrane that separates it from the rest of the organelles.
- The cytoplasm is a solution that surrounds the nucleus, and it contains the rest of the organelles that the cell needs for its functions.
- The cell membrane is the structure that encloses all the cytoplasm and the nucleus. It is made of phospholipids, proteins, and cholesterol, which allows the passage of certain substances.
Answer:
The cell wall provides the cell with protection from all the unfavorable conditions. ... Without the cell wall, the plant cell will collapse. Uptake of nutrients would be tough and the cell would be without any protection. Hence the plant would eventually die.

Image result for Is work done when you carry a book across the room at a constant velocity
Work is not done when you carry an object forward. You may have learnt that carrying an object and moving horizontally at a constant velocity has no work done. The truth is, there is a slight amount of work done due to overcoming air resistance in the horizontal direction.
