Cell structure (with pictures)

STUDY
PLAY
Nucleolus
The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
Chromatin
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
Smooth Endoplasmic reticulum
An endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down.
Cytosol
the part of the cytoplasm that includes molecules and small particles, such as ribosomes, but not membrane-bound organelles
Mitochondrion
an organelle containing enzymes responsible for producing energy
Lysosome
a small round cell structure that contains chemicals that break down large food particles into smaller ones
Centrioles
two tiny structures located in the cytoplasm near the nuclear envelope
Centrosome matrix
Granular looking matrix that contains paire centrioles; generates microtubules, and organizes the mitotic spindle in cell division.
Cytoskeletal elements: Microtubule, Intermediate filaments
Peroxisome
A microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide. (Detoxification)
Secretion being released form cell by exocytosis
Golgi apparatus
stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
Ribosomes
site of protein synthesis
Rough endoplasmic reticulum
Chemically modifies proteins made by the ribosomes attached to its surface, which are then use in the cell membrane or for transport outside the cell
Plasma membrane
thin outer boundary of a cell that regulates the traffic of chemicals between the cell and its surroundings
Nucleus
a part of the cell containing DNA and RNA and responsible for growth and reproduction
Nuclear envelope
A double membrane that surrounds the nucleus in the cell
Interphase
period of the cell cycle between cell divisions
Prophase
the longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
Metaphase
The phase of mitosis during which the chromosomes line up across the center of the cell
Anaphase
The Phase of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle
Telophase and cytokinessis
the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle
