Study Notes

Plant Cell Structure

Cell Wall: Rigid outer layer providing support and protection for the plant cell.
Cell Membrane: Semi-permeable barrier that regulates the movement of substances in and out of the cell.

Organelles and Their Functions

Golgi Body: Responsible for modifying, packaging, and distributing proteins and other materials received from the Endoplasmic Reticulum.
Chloroplast: Site of photosynthesis, contains chlorophyll to capture sunlight and convert it into energy, exclusive to plant cells.
Endoplasmic Reticulum (ER): Network of membranes forming passageways for transporting proteins and materials within the cell.

Storage and Energy

Vacuole: Storage sac for nutrients, waste products, water, and other materials, significant in maintaining turgor pressure in plant cells.
Nucleus: Control center of the cell; contains genetic material (DNA) that directs cellular activities.
Mitochondrion: Known as the powerhouse of the cell; involved in the production of ATP, the energy currency of the cell.

Protein Synthesis

Ribosomes: Small structures either attached to the ER or free-floating in the cytoplasm; vital for protein synthesis.
