Plant cells are the basic unit of life in plants. They are responsible for carrying out all of the functions that keep the plant alive, such as photosynthesis, cell growth, and reproduction.
One of the most distinctive features of plant cells is the cell wall. The cell wall is a layer of tough, flexible tissue that surrounds the cell membrane and provides support and protection for the cell. It is made up of cellulose fibers, which are long chains of sugar molecules that are tightly packed together.
Inside the cell wall is the cell membrane, which is a thin, flexible layer that surrounds the cell and separates the inside of the cell from the outside environment. The cell membrane is made up of lipids, or fats, and proteins. It is semi-permeable, meaning that it allows some substances to pass through it, but not others.
Inside the cell membrane is the cytoplasm, which is a gel-like substance that contains all of the cell's organelles. Organelles are tiny structures inside the cell that perform specific functions.
One important organelle in plant cells is the chloroplasts, which are responsible for photosynthesis. Photosynthesis is the process by which plants convert sunlight into energy. Chloroplasts contain chlorophyll, which is a pigment that absorbs sunlight and helps to convert it into energy.
Another important organelle in plant cells is the vacuole. The vacuole is a large, fluid-filled structure that helps to support and protect the cell. It also stores water and other substances that the cell needs to function.
Plant cells also have a nucleus, which is the "brain" of the cell. The nucleus contains the cell's genetic material, or DNA, which carries the instructions for all of the cell's functions.
In summary, plant cells are the basic units of life in plants and are responsible for carrying out all of the functions that keep the plant alive. They have a cell wall, cell membrane, cytoplasm, organelles, and a nucleus. These features work together to help the plant grow and thrive.

The plant cell wall is also involved in protecting the cell against mechanical stress and providing form and structure to the cell. Chromoplasts have red, orange and yellow coloured pigments which provide colour to all ripe fruits and flowers. Both plant and animal cells contain a nucleus along with similar organelles. They are used for the storage of protein, lipid and starch.

The cell membrane plays an important role in regulating the entry and exit of specific substances within the cell. Following are some of the different types of plant cells: Collenchyma Cells They are hard or rigid cells, which play a primary role in providing support to the plants when there is restraining growth in a plant due to lack of hardening agent in primary walls. They perform the function of cellular waste disposal by digesting worn-out organelles, food particles and foreign bodies in the cell.
