• What is a chloroplast? Explain how a root of a plant, that lacks Chloroplasts, gets energy. What organelles are involved with converting the energy for the roots?
• Explain why animal cells do not require a cell wall and a central vacuole. Please read Unit 2, Lesson 3, Page 9 to answer this question correctly. 5-4 SENTENCES
A chloroplast is an organelle found in plant cells that is responsible for trapping sunlight and using it to convert carbon dioxide and water into glucose through the process of photosynthesis. The roots of a plant lack chloroplasts and cannot carry out photosynthesis. Instead, roots obtain energy through the process of respiration. Respiration occurs in the mitochondria, an organelle found in all cells, including plant and animal cells. Animal cells do not require a cell wall because they have a flexible cell membrane that provides support and protection. Additionally, animal cells do not require a central vacuole because they have smaller vacuoles spread throughout the cell that perform similar functions, such as storing waste and maintaining cell shape.
