The document provides information about the key organelles in plant cells: 1) The nucleus contains the cell's genetic material and controls its activities. The nucleolus is found within the nucleus and makes ribosomes. 2) The mitochondrion and chloroplast help provide cells with energy through respiration and photosynthesis respectively. 3) Other organelles mentioned include the cell wall, which supports and protects the plant cell, the lysosome which breaks down food, the ribosome which synthesizes proteins, the cell membrane which regulates what enters and leaves the cell, the vacuole which stores materials, the endoplasmic reticulum which modifies proteins, the nuclear envelope which allows materials to pass into the nucleus, and
