Cell Part Cell membrane Function Nucleus Chromosomes Controls what enters and leaves the cell Controls what enters and leaves the nucleus Control center of the cell Genetic information in the nucleus Endoplasmic Reticulum Ribosome Golgi Body Transport system in cell Organelle makes proteins Organelle packages proteins Vacuole Lysosome Mitochondria Stores water and/or waste Breaks down old cell parts Organelle for cellular respiration – provides energy Nuclear membrane Eukaryotic Cells Plant Cells have, and Animal Cells don’t • Chloroplasts – organelle responsible for photosynthesis • Cell Walls – a structure outside of the membrane to provide support • Very large vacuoles to store extra water This is a typical plant cell • It contains a cell wall, chloroplasts, a very large vacuole. • Why do plants need large vacuoles? •ANSWER: This is where food and water are stored. 52 Compared to annual rings of trees that have experienced years of sufficient rainfall, the annual rings of trees that have experienced a dry period will — These would F be softer indicate G grow at a faster rate more water, not less H be thinner J photosynthesize at a faster rate
