1. The plant cells are more rectangular because their rigid cell walls maintain a defined shape, while animal cells lack cell walls and have more flexible membranes allowing varied shapes.
2. Chloroplasts contain chlorophyll, which captures sunlight energy to convert carbon dioxide and water into glucose and oxygen through photosynthesis.
3. The chloroplasts move toward the light source to maximize light absorption for photosynthesis, increasing energy production for the cell.
4. If the plant doesn’t receive enough light, it may become etiolated—stretched and pale—as it grows toward any available light source to survive.
5. Plants need soil for water, minerals, and physical support; however, hydroponic systems show plants can grow without soil if nutrients and water are provided directly.
6. The environment must provide adequate light, water, carbon dioxide, and appropriate temperature for photosynthesis to occur efficiently.
7. Some plants like cacti have thick, waxy cuticles and reduced leaves to minimize water loss in arid environments, adapting their structure to conserve water.
8. Plants that live in low-light conditions often have larger, broader leaves to capture more available light, maximizing photosynthetic efficiency in shaded areas.
