cell membrane ~ the semipermeable membrane enclosing the cytoplasm of a cell.

nucleus ~ a specialized, usually spherical mass of protoplasm encased in a double membrane, and found in most living eukaryotic cells, directing their growth, metabolism, and reproduction, and functioning in the transmission of genic characters.

cytoplasm ~ the cell substance between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton, and various particles.

vacuole ~ A small cavity in the cytoplasm of a cell, bound by a single membrane and containing water, food, or metabolic waste.

chloroplasts ~ A chlorophyll-containing plastid found in algal and green plant cells.

Cell Membrane - The membrane that separates the cell wall and the cytoplasm, and regulates the flow of material into and out of the cell

Nucleus-a part of the cell containing DNA and RNA and responsible for growth and reproduction

Cytoplasm-The material inside a cell located between the cell's nucleus and the cell membrane. Cytoplasm is a mixture of water, dissolved ions, sugars, and proteins. Cytoplasm includes a number of filaments and tubules, all arranged in a three dimensional lattice, that provide support for the cell's organelles.

Vacuoles-Any spaces or cavities within a cell. They may function in digestion, storage, secretion, or excretion.

Chloroplasts -Oval, chlorophyll-bearing structures inside the cells of leaves which act as factories to produce sugar for plant growth from CO2 and water. The energy used for this conversion is sunlight, captured by the chlorophyll.
