Structure of the generalized cells (with image)

Cytoplasm

B, a jellylike fluid inside the cell in which the organelles are suspended

Nuclear Envelope

N, layer of two membranes that surrounds the nucleus of a cell

Chromatin

A, granular material visible within the nucleus; consists of DNA tightly coiled around proteins

Microvilli

E, Projections that increase the cell's surface area

Mitochondria

F, Powerhouse of the cell, organelle that is the site of ATP (energy) production

Smooth Endoplasmic Reticulum

H, no ribosomes are found on surface; contains collection of enzymes that perform special tasks that include the synthesis of membrane lipids and detoxification (Lipid Manufacture)

Rough Endoplasmic Reticulum

I, a region that is recognized by the grainy appearance of the ribosomes on their outer surface, where the cell's proteins are made

Lysosome

J (smaller vacuole to the left of F), cell organelle filled with digestive enzymes needed to break down certain materials in the cell

Golgi Body

K, a structure in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell (FedEx)

Nucleus

L, a part of the cell containing DNA and RNA and responsible for growth and reproduction

Nucleolus

M, The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus

Ribosome

P, small particle in the cell on which proteins are assembled; made of RNA and protein (found in Rough ER and cytoplasm)

Peroxisome

Q, A microbody containing bleach, producing and then degrading hydrogen peroxide.

Plasma Membrane

R, thin flexible barrier that regulates what enters and exits the cell; composed of two layers of lipids
