Vacuole - Cytoplasm - Mitochondria - Chloroplast -

Vacuole - part of a plant cell that maintains rigid cells to support the plant.

Cytoplasm - part of a cell where the chemical reactions happen.

Mitochondria - an organelle containing enzymes responsible for producing energy.

Chloroplast - organelles in plant cells and other eukaryotic organisms that conduct photosynthesis; captures light energy.

Ribosome - small organelles found in all cells; involved in the production of proteins.

Cell wall - Cilia - Ciliated epithelial cells - Sq

Cell wall - located outside the cell membrane and provides these cells with structural support and protection and also acts as a filter.

Cilia - a hairlike projection from the surface of a cell; provides locomotion in free-swimming unicellular organisms.

Ciliated epithelial cells- sweep clean germs and dust trapped in the mucus.

Squamous - are the flat cells found on the outer surface of the cervix.

Root - an organ of a plant which mainly lies under the soil.

Root hair cell - Photosynthesis - Magnification -

Root hair cell - found near the tip of the roots; water and minerals are caught by the cell and transported to the root.

Photosynthesis - the process by which plants generate Carbohydrates and oxygen from carbon dioxide, water and light.

Magnification - process of enlarging something only in appearance.

Microscope - an instrument to see objects too small for the naked eye.

Objective Lens - Eye-piece Lens - Stage

Objective Lens - an instrument on the microscope.

Eye-piece Lens - another instrument on the microscope; this is where we place our eye.

Stage - the platform where we place the 'slide'.

Tissue - a group of cells that are the same type.

Organ - a collection of different types of tissues.

Organ System - a collection of different types of organs that carry out major jobs in the body.
