This level of organization is a "Group of cells working together"

These specialized cells are very long and allow for electrical signals and impulses.

The primary function of this specialized cell is to absorb water and nutrients from the soil, and store them in a large central vacuole.

The active site is where the _________ interacts with the enzyme

The amount of energy needed for a reaction to take place is known as _______ _______

proteins that reduce the amount of energy needed to start biochemical reactions within living cells, i.e. catalysts

This organ system removes waste from the body.

Single-celled organisms that do not have a true nucleus or membrane-bound organelles.

Organisms that possess a clearly defined nucleus.

Compartments within the cell that perform a specific function.

antibiotic

prokaryotes

Organelle that contains the DNA and controls the processes of the cell

Cell organelle filled with enzymes needed to break down certain materials in the cell

An organelle that prepares proteins for shipping them out of the cell

Found in some protists and in most plant cells, a large, fluid-like organelle that stores water, enzymes, metabolic wastes, and other materials.

An organelle that transports proteins inside of the cell

A structure in the cells of plants and some other organisms that captures energy from the sun and uses it t produce food.

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

Outer layer of plant cells that provides support and structure

a "Y" shaped protein molecule that recognizes foreign substances and bonds with specific antigens.

Non-specific scavenger cell; engulfs foreign invaders and helps protect us from pathogens

The process of "eating" or engulfing cells

Molecule that forms a double layered (bi-layer) cell membrane. (phosphate, glycerol and two fatty acid chains)

The movement of molecules from areas of high concentration to areas of lower concentration.

The diffusion of water molecules across a semipermeable membrane.

The movement of molecules across the cell membrane without the use of energy by the cell.

A solution that has a higher amount of dissolve particle compared to another solution.

A solution that has a lower amount of dissolved particles compared to another solution.

The diffusion of molecules assisted by protein channels that pierce a cell membrane.

The energy-requiring movement of molecules across a cell membrane, going from a lower concentration to a higher concentration.

The uptake of liquids or large molecules into a cell by the inward folding of the cell membrane.

The release of a substance out of a cell by the fusion of a vesicle with the cell membrane.

Third phase of mitosis in which sister chromatids are pulled apart.

Chromosomes are made up of two identical sister _____________.

The last of the Three MAIN parts of the Cell Cycle. This is the final step when the stretched-out cell officially splits into two new, identical cells. (The cytoplasmic division bringing about the separation into two daughter cells.)
