a jellylike fluid inside the cell in which the organelles are suspended
The thin layer surrounding a cell's contents. Acts as a gatekeeper. Consists of a phospolipid bilayer in which proteins are embedded; communicates with other cells.
a part of the cell containing DNA and RNA and responsible for growth and reproduction
thread like structures that have genetic info that is passed down from one generation to the next
double membrane perforated with pores that control the flow of materials in and out of the nucleus
The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
Powerhouse of the cell, organelle that is the site of ATP (energy) production
Rough Endoplasmic Reticulum
System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm
Smooth Endoplasmic Reticulum
no ribosomes are found on surface; contains collection of enzymes that perform special tasks that include the synthesis of membrane lipids and detoxification; the liver contains a lot of smooth er
stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
cell organelle filled with enzymes needed to break down certain materials in the cell
Contain oxidase enzymes that detoxify alcohol, hydrogen peroxide, and other harmful chemicals
specialized peroxisomes found in fat-storing tissues of plant seeds that have enzymes which convert fatty acids to sugars; used for energy until photosynthesis occurs to produce its own sugar
series of compartments that molecules pass through before reaching lysosomes, they sort the ingested molecules and recycle some back to plasma membrane. Contain enzymes used in oxidative reactions that break down lipids and destroy toxic molecules.
formed by phacogytosis; pinches off of the plasma membrane and encloses a food particle
saclike organelles that expand to collect excess water and contract to squeeze the water out of the cell
a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
Hollow tubes made of a protein called tubulin
fine, threadlike proteins found in the cell's cytoskeleton
whiplike tails found in one-celled organisms to aid in movement
One of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope; play a role in cell division.
a thin membrane around the cytoplasm of a cell
Primary Cell Wall
A relatively thin and flexable cell wall furthest outside that is first secreted by a plant cell
Secondary Cell Wall
in plants, a strong and durable matrix often deposited in several laminated layers for cell protection and support.
A membranous sac in a mature plant cell with diverse roles in reproduction, growth, and development.
stores starch, pigments, and toxic substances in plants
organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
plastid containing pigments other than chlorophyll usually yellow or orange carotenoids
Unpigmented plasids that store starch grains, abundent in cells of stems, tubers, and seeds
A common precursor of the different plastids, including the chloroplast, chromoplast, and amyloplast.
non membrane bounded organelles responsible for protein synthesis
short structures projecting from a cell and containing bundles of microtubules that move a cell through its surroundings or move fluid over the cell's surface

a part of an organism consisting of an aggregate of cells having a similar structure and function
a collection of tissues that carry out a specialized function of the body
group of organs that work together to perform a specific function
