Organelle parts of a cell

Endocytosis

Bringing large clumps of materials into the cell

Exocytosis

Moves out of the cell

Endoplasmic Reticulum (ER)

A system of transport pathways used to transport materials through the cell. Smooth ER- have no ribosomes Rough ER- have ribosomes attached.

Lysosome

Breaks down/ digest materials into small molecules that can be used by the rest of the cell. Also, they help break down organelles that are no longer useful to the cell.

Passive Transport

Does not require energy.

Chloroplast

Found in plant cells; captures the energy from sunlight and makes food for plants. Helps with photosynthesis

Ribosome

Found throughout the cytoplasm in a cell; this is where proteins are made. Make proteins.

Golgi Apparatus (body)

Modifies, sorts, and packages materials from the ER for storage in the cell or release outside the cell.

Concentration

Molecules that water loves.

Cytoskeleton

Network of Protein filaments in a cell that gives the cell its shape and helps with movement

Diffusion

Passing through and change shape.

Photosynthesis

Photosynthesis is how plants get there energy from the sun.

Cell Transport

Process by which cell brings materials in and out of the cell.

Vacuole

Stores materials such as water, salts, proteins, and carbohydrates. Plant cells have larger vacuoles than animal cells.

Cell Wall

Strong, supporting, and protective outer layer around the cell membrane. Only found in plant cell

Centriole

Structure in a animal cell that helps with cell division

Chromatin

Substance found in chromosomes that consists of DNA tightly coiled. Found in the nucleus

Nucleus

The control center of the cell that contains the cell's genetic material in the form of DNA. Controls activities of the cell.

Cytoplasm

The gel-like portion of the cell outside of the nucleus. Holds all the organelles in place inside the cell.

Nuclear Membrane

The physical barrier separating the nucleus from the cytoplasm. Outer covering/layer of the nucleus. Controls what goes in and out of the Nucleolus.

Cell Membrane

Thin, flexible barrier that surrounds all cells; controls what enters and leaves the cell.

Hypertonic

Water move out of the cell

Isotonic

Water moves into and out of the cell

Hypotonic

Water moves into the cell

Facilitated diffusion

When molecules are to big to squeeze through the cell

Semi-permeable membrane

Allows things to move in and out of the cell.

Flagella

Also used for movement; flagella are long and thin and produce movement in a wavelike motion. Tail like structure

Nucleolus

Dark area inside the nucleus where ribosomes are made. Nucleolus makes ribosomes.

Mitochondria

Makes energy for the cell to use. The powerhouse of the cell.

Active transport

Requires energy

Cilia

Short hair like structure that helps the cell to move.

Osmosis

The diffusion or movement of water.
