Meaning • Plant cell: are eukaryotic cells that differ in several key

respects from the cells of other eukaryotic organisms. Their distinctive features include:

• nucleus, Plasmodesma, Dictyosome, Dictyosome, Nucleus, Nuclear envelope, Endoplasmic reticulum, Peroxisome, Chloroplast,

• Mitochondria, Cytosol, Free ribosome, Tonoplast, Vacuole, cell wall, Plasma membrane, Thylakoids, and Starch grain

Nucleus

• Nucleus: a central part about which other parts are grouped or gathered. Also sometimes referred to as the "control center", is a membrane-enclosed organelle found in eukaryotic cells.

Plasmodesma

• An intercellular bridge.

Chromatin

• Chromatin: a coloring substance in the nucleus of the cell.

Dictyosome

• Dictyosome: cellular organelle that elaborates sugars and proteins.

Nuclear Envelope

• Nuclear envelope: membrane surrounding the nucleolus.

Cell Wall• Cell Wall: the definite boundary or wall that is

part of the outer structure of certain cells, as a plant cell.

Endoplasmic Reticulum

• Endoplasmic reticulum: a formation within the cytoplasm that plays a role in the production of various substances.

Peroxisome

• Peroxisome: cytoplasmic organelle which contains enzymes.

Chloroplast

• Chloroplast : granule of chlorophyll, which is needed for photosynthesis.

Mitochondria

• Mitochondria : granule that plays an important role in the respiration and energy-releasing reactions in living cells.

Cytosol

• Cytosol : liquid part of the cytoplasm.

Free Ribosome

• Free ribosome : cytoplasmic organelle which is responsible for protein synthesis.

Vacuole

• Vacuole: space with the cytoplasm of a cell containing various substances.

Tonoplast

• Tonoplast : vacuolar membrane.

Plasma membrane

• Plasma membrane: envelope of plasma.

Thylakoids• Thylakoids: membranous molecular

structures involved in photosynthesis.

Starch Grain

• Starch Grain: starch granule.
