Cell Wall |
A rigid layer of polysaccharides on the outer layer of the plasma membrane on plants and fungi. |
|
Nucleus |
the central and most important part of an object, movement, or group, forming the basis for its activity and growth. |
|
Nucleolus |
a small dense spherical structure in the nucleus of a cell during interphase. |
|
Ribosome |
a minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA. |
|
Lysosome |
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane |
|
Smooth Endoplasmic Reticulum |
Its main functions are the synthesis of lipids, steroid hormones, the detoxification of harmful metabolic byproducts, and the storage and metabolism of calcium |
|
Rough Endoplasmic Reticulum |
series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins |
|
Golgi Apparatus |
a complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport |
|
Vacuoles |
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid |
|
Chloroplasts |
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place |
|
Mitochondria |
The "powerhouse" of the cell |
|
Cell Membrane |
the semipermeable membrane surrounding the cytoplasm of a cell |
|
Cytoplasm |
the material or protoplasm within a living cell, excluding the nucleus |
|
Nucleoplasm |
the main function is to store DNA and facilitate an isolated environment where controlled transcription and gene regulation is enabled |
|
Microtubules |
polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells |
|
Microfilaments |
also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton |
|
Chromosomes |
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes |
|
Nuclear Membrane/Envelope |
The nuclear envelope, also known as the nuclear membrane, is made up of two lipid bilayer membranes which in eukaryotic cells surrounds the nucleus, which encases the genetic material |
|
Cilia |
The cilium is an organelle found on eukaryotic cells in the shape of a slender protuberance that projects from the much larger cell body. (there are two of them one acts as a sensory organelle) |
