1. Why are lysosomes important to the heal of cells?
They break down worn-out cell parts that are no longer needed.
2. Which of the following organelles provide structure and rigidity to a plant cell?
Cell wall.
3. What would happen to a plant if the chloroplasts in its cells became damaged?
The plant would not make glucose and oxygen.
4. Why do plant root cells lack chloroplasts?
Roots are underground and are not exposed to sunlight.
5. What is the main difference between prokaryotic and eukaryotic cells?
Prokaryotes lack membrane-bound organelles.
To find the answer to question 1, you would need to understand the function of lysosomes. Lysosomes are membrane-bound organelles found in cells that contain enzymes responsible for breaking down worn-out cell parts, toxins, and foreign invaders. These enzymes help recycle the cell's components and eliminate waste materials.
For question 2, the answer is the cell wall. The cell wall is a rigid structure that surrounds plant cells, providing support and protection. It is composed of cellulose and other structural molecules, giving the plant cell its shape and rigidity.
To answer question 3, you should know about the role of chloroplasts. Chloroplasts are organelles responsible for photosynthesis in plant cells. They convert sunlight, water, and carbon dioxide into glucose and oxygen. If the chloroplasts become damaged, the plant will not be able to produce glucose and oxygen, impacting its ability to carry out vital metabolic processes.
For question 4, the answer lies in the location and purpose of the root cells. Roots are underground and typically do not receive much sunlight. Chloroplasts require sunlight for photosynthesis, so there is no need for chloroplasts in root cells since they cannot carry out this process in the absence of light.
To answer question 5, you need to understand the distinction between prokaryotic and eukaryotic cells. Prokaryotic cells, such as bacteria, lack membrane-bound organelles, including a nucleus. Eukaryotic cells, on the other hand, have a nucleus and other membrane-bound organelles. This difference in cell structure is one of the main distinctions between prokaryotic and eukaryotic cells.
