Terms in this set (...)

Petal
The colorful, pretty parts of the flower. This part of the flower attracts pollinators.
Monocot
A plant that has only one cotyledon. Corn is an example.
Vascular
A type of plant that has specialized tissues or tubes that transport materials from one part of the plant to another.
Cell Wall
This surrounds the plant cell and helps support and protect the plant.
Root
The part of the plant that is usually found underground. They help anchor the plant and bring in food and water.
Pollination
The movement of the pollen from the anther to the stigma. Bees and other insects are important in this process.
Cotyledon
Found within the seed coat. They are a food source for seeds.
Ovary
In flowering plants, the lower part of a pistil that produces eggs in ovules.
Flower
The part of a plant that makes seeds.
Ovule
The part of the ovary that becomes the seed. Also called an egg.
Leaf
The food-making factory of a plant. They are usually green, flat to catch light, and attached to a stem.
Chlorophyll
A green pigment that captures light energy for photosynthesis.
Embryo
The baby plant, or young plant, within the seed.
Gymnosperm
A plant that produces seeds that are not enclosed by a protective fruit. They produce cones instead of flowers.
Dicot
A plant that has two cotyledons. A lima bean seed is an example.
Pollen
Fine, powder-like material you see covering the anthers. This is what bees collect. It is also the male reproductive organ.
Cuticle
A protective covering that is often found on the outside of leaves, stems and fruits. It often gives these plant parts a waxy or shiny appearance.
Stamen
The male reproductive structure of a flower that produces pollen and consists of an anther at the tip of a filament.
Nonvascular
Simple plants, like liverworts and mosses, that contain no roots, stems, or leaves. They lack tubes to transport nutrients.
Fruit
The part of the plant that we normally eat. It is considered a ripened ovary and protects the seeds.
Pistil
The female reproductive part of a flower that produces seeds and consists of an ovary, style, and stigma.
Angiosperm
A flowering plant that produces seeds within a fruit.
Seed Coat
The protective outer layer of a seed.
Seed
A packaged little plant (embryo) with food around it (cotyledon) and a covering protecting it (seed coat).
Stem
The main body of a plant that holds up the limbs, leaves and flowers.
Anther
The yellow, pouch-like part inside of the flower that holds pollen grains. It is usually on top of the filament.
Xylem
The type of tissue, or tube, in vascular plants that provides support and conducts water and nutrients from the roots.
Fertilization
The joining of pollen with an ovule to form a seed.
Pollinator
An animal, usually a bee, butterfly, bird, or moth, that transports pollen from one flower to another.
Stigma
Found on the pistil. It is the sticky bulb that you see in the center of flowers and is the part where the pollen lands and starts the fertilization process
Photosynthesis
A process by which a plant produces its food using energy from sunlight, carbon dioxide from the air, and water from the soil.
Style
Part of the pistil. This is the long stalk that is found directly under the stigma.
Germination
The process in which a seed begins to grow.
stomata (stoma)
Small openings on the underside of a leaf through which oxygen and carbon dioxide can move
phloem
Transports glucose and other dissolved sugars (food) from the leaves to other parts of the plant.
guard cells
control the opening and closing of stomata
meristematic tissue
plant tissue found only in the tips of shoots and roots; responsible for plant growth
dermal tissue
The protective covering of plants; generally a single layer of tightly packed epidermal cells covering young plant organs formed by primary growth.
ground tissue
tissue between the dermal tissue and vascular tissue of a non-woody plant that functions in photosynthesis, storage, and support
Cambium
A layer of cells in a plant that produces new phloem and xylem cells.
Transpiration
loss of water from a plant through its leaves
Cones
are made up of many scales which are a kind of shelter for the seed.
