2. Objectives Identify and name the main organelles found in a plant cell Describe the function of each organelle, including the Cell membrane, cytoplasm, and the nucleus

3. Cell organelle’s structure and function Cell Membrane Structure: A thin, flexible barrier that surrounds the cell. Function: Controls what enters and leaves the cell (selective permeability).

4. Cytoplasm Structure: A jelly-like fluid called cytosol that fills the inside of the cell and it contains all the organelles suspended in it Function: Supports and holds organelles in place.

5. Nucleus Structure: A large, spherical organelle surrounded by a double membrane called the nuclear envelope, which has pores. Contains chromatin (DNA and proteins), which condenses into chromosomes during cell division. Function: The control center of the cell. Stores the cell’s genetic material (DNA).
