Question

plant cells have organelles that animal cells do not or that are used differently. specifically, plant cells have a cell wall, larger vacuoles, and chloroplasts. explain the function of these organelles and why animals cells do not have these organelles.

Explanation:

1. Cell wall: It provides structural support and protection for plant cells, maintaining cell shape and preventing excessive water - uptake. Animals have a skeletal system and connective tissues for support and protection, so they don't need a cell wall.
2. Larger vacuoles: In plants, they store water, nutrients, and waste products, and also help maintain turgor pressure for cell rigidity. Animal cells have smaller vacuoles for temporary storage as they do not need to maintain the same level of turgor or store large amounts of water for photosynthesis - related processes.
3. Chloroplasts: These are the sites of photosynthesis in plants, converting light energy into chemical energy (glucose). Animals are heterotrophs and obtain energy by consuming other organisms, so they do not have chloroplasts for photosynthesis.

Answer:

• Cell wall: Provides support and protection. Animals have other support mechanisms.
• Larger vacuoles: Store substances and maintain turgor. Animal cells have smaller vacuoles for less - extensive storage.
• Chloroplasts: Site of photosynthesis. Animals are heterotrophs and don't photosynthesize.
