Cel Structure

Smooth ER

a network of membrane-bound tubes inside plant and animal cells that makes lipids, processes toxins, and stores calcium

Centrosome Matrix

s a dense protein network surrounding the centrioles that nucleates, anchors, and organizes cellular microtubules, concentrated around the centrioles

Nucleus

A membrane-bound organelle found in eukaryotic cells (cells with a distinct nucleus) that houses the cell's genetic material (DNA). It is often called the "brain" or control center of the cell.

Microtubules

tiny, hollow tube-like structures inside the cytoplasm of plant and animal cells that help support cell shape, move organelles, and separate chromosomes during cell division

Nucleolus

a dense, membrane-free structure inside the nucleus of a cell that builds the parts needed to make proteins

Centrioles

barrel like, Help organize the mitotic spindle that pulls and separates chromosomes into daughter cells during mitosis and meiosis

Rough ER

a continuous membrane organelle in eukaryotic cells that is studded with ribosomes and plays a central role in protein synthesis

Ribosomes

microscopic cellular structures made of ribosomal RNA and proteins that act as the primary site for protein synthesis in all living cells

Chromatin

a complex mixture of DNA, RNA, and proteins that packages long DNA molecules into a compact, dense structure inside the nucleus of eukaryotic cells

Lysosome

a membrane-bound cell organelle that contains digestive enzymes to break down waste, old cell parts, and foreign invaders

Golgi Apparatus

a membrane-bound cell organelle that modifies, sorts, and packages proteins and lipids for transport to different locations inside and outside the cell

Nuclear Envelope

a double-membrane barrier that surrounds and protects the genetic material inside the nucleus of a eukaryotic cell

Cytosol

the clear, jelly-like fluid that fills the inside of a cell and surrounds the cell's internal parts

Mitochondrion

membrane-bound cell organelles that generate most of the chemical energy needed to power a cell's biochemical reactions

Peroxisome

a small, membrane-bound organelle found in the cytoplasm of nearly all eukaryotic cells that metabolizes fats and neutralizes toxic substances

Intermediate Filaments

ropelike cytoskeletal structures with an average diameter of 10 nanometers that provide mechanical strength and support to eukaryotic cells
