7.2 Cell Structure
The structure of the cell
Terms in this set (20)
"little organs" in the cell
Portion of the cell outside the nucleus. It works with the nucleus in the business of life.
Contains nearly all the cell's DNA and coded instructions for making proteins and other important molecules.
Store materials like water, salts, proteins and carbohydrates.
Are small organelles filled with enzymes. Breaks down lipids, carbohydrates, and proteins into small molecules that can be used for the cell.
They also involve the breaking out of organelles that have outlived their usefulness.
Give the cells their shape and internal organization by a network of filaments.
Helps maintain the cell maintain its shape and also involved in movement.
Threadlike structures made up of protein called actin. Form extensive networks in some cells and produce a tough flexible framework that supports the cell.
Hollow structures made up of proteins and tubulins. Important in cell division because they form the mitotic spindle, which helps separate chromosomes.
Located near the nucleus and help organize cell division
Where proteins are assembles. Produce proteins by following coded instructions that come from DNA.
Lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell.
Where the synthesis of proteins occur. It is given its name because ribosomes are found on its surface. Proteins here will be released or secreted.
Collection of enzymes that involves specialized tasks. Involves detoxification of drugs and synthesis of membrane lipids.
Proteins produced in the Rough ER move here. Modifies, sorts and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell.
Captures the energy from sunlight and convert it into food that converts it into food that contains chemical energy in a process called photosynthesis.
Convert the chemical energy stored in food into compounds that are more convenient for the cell to use.
Provide much of the strength needed for plants to stand against the force of gravity.
Made of double-layered sheets called lipid bilayers. Regulates what enters and leaves the cell and provides protection and support to the cell.
Gives cell membranes a flexible structure that forms a strong barrier between the cell and its surroundings.
Why are cells selectively permeable?
Meaning that some substances can pass across them and others cannot.
