Parts of Plant Cells

Cell Wall

• Non-living structure that surrounds the plant cell.

• It protects and supports the cell and is made up of a tough fiber called CELLULOSE.

Mitochondria

• It is surrounded by a double membrane with a series of folds called cristae.

• It is the center of cellular respiration, transfer of energy to different cell content and contains its own DNA, and is believed to have originated as a captured bacterium.

• It is the powerhouse in the cell.

Vacouls

Membrane surrounded "bags" that contain water and storage materials in plants.

Chlorophyl

Contains a green pigment known as chlorophyll which is important for photosynthesis.

Peroxisomes

• Microbodies

• Produced and degraded hydrogen peroxide, a toxic compound that can be produced during metabolism.

• It contains the enzyme catalase.

Centrioles

Self-replicating organelles made up of nine bundles of microtubules and are found only in animal cells

Cilia and Flagella

Essential for locomotion and movement of materials

Microtubules

These straight, hollow cylinders are found throughout the cytoplasm of all eukaryotic cells (prokaryotes don't have them) that carry out a variety of functions, ranging from transport to structural support.

Endosomes

Membrane-bound vesicles, formed via a complex family of processes collectively known as endocytosis, and found in the cytoplasm of virtually every animal cell.

Intermediate fillament

• Are a very broad class of fibrous proteins that play an important role as both structural and functional elements of the cytoskeleton.

• Ranging in size from 8 to 12 nanometers, intermediate filaments function as tension bearing elements to help maintain cell shape and rigidity.

Micro-fillaments

• Solid rods made of globular proteins called actin.

• Primarily structural in function and are an important component of cytoskeleton.

Cytoskeleton

The internal framework of the cell, gives shape to the cell
