What is a plant

chlorophyll A green photosynthesis pigment found in the chloroplast of plants, algea, and some bacteria.
photosynthesis The process by witch plants and other autotrophs capture and use light energy to make food from carbon dioxide and water.
tissue a group of similar cells that perform a specific function.
chlorplasts an organelle in the cell of plants and some other organisms that capture energy from that cells can use in making food.
vacuole A sac-like organelle that stores water, food, and other materials.
cuticle The waxy, waterproof layer that covers the leaves and stems of most plants.
vascular tissue The interanal transporting tissue in some plants that is made up of tube like structures that carry water, food, and minerals.
Non vascular Plant A low growing plant that lacks true vascular tissue for transporting materials.
Rhizoid A thin root like structure that anchors a moss and absorbs water and nutrients for the plant.
Vascular Plant A plant that has true vascular tissue for transporting materials.
Phloem The vascular tissue through which food moves in some plants.
Xylem The vascular tissue through which water and minerals move in some plants.
Frond The leaf of a fern plant.
Pollen Tiny structure produced by seed plants that contain the cell that later becomes the sperm cell.
Seed The plant structure that contains a young plant and a food supply inside a protective covering.
Gymnosperm A plant that produces seeds directly on the scales of cones.
