WORDS+TO+KNOW

Roots- underground organs that absorb water and minerals for the plant. This relates to our project because the bean plants are now growing roots.
 * __WORDS TO KNOW!!!__**

Leaves- photosynthetic organ that contains one or more bundles of vascular tissue The leaves are relevant to our project because our bean plants have leaves

Stem- supported structures that connect roots and leaves, carrying water and nutrients between them. The bean plants are growing stems and growing taller.

Gymnosperm-one of the two groups that seed plants are divided into, they bear the seed directly to the surface of the cone. This relates to our bean seeds because, our bean plants grew out of a seed and were directed to the surface of the seed.

Angiosperm- the other group a seed pant is divided into, bears their seeds within a layer of tissue that protects the seed. This protects our bean plant from any unwanted stuff.

Seed- an embryo of a plant that is encased in a protective covering and surrounded by a food supply. The seed is very important to our project because the bean is made out of a seed and with out it, it would not be able to grow.

Seed coat- a layer that surrounds the seed to protect it from drying out. These are important to our investigation because with out a seed coat our bean plants would most likely dry out and not grow.


 * Epidermal Cells- an outer surface of a plant that re often covered with a thick waxy layer that protects water loss and injury.**

Buds- Contain undeveloped tissue that can produce new stems and leaves. In the spring some flowers buds bloom.

Fibrous Roots- Roots that branch to such an extent that no single root grows larger than the rest. Fibrous roots grow out like little strings.

Lignin- A substance that makes cell walls rigid enables vascular plants to grow upright and reach great heights. Lignin is needed in plants so that the plants don’t fall over when growing!

Mesophyll- A specialized ground tissue found in the bulk of most leaves. Mesophyll is a special tissue that help the plant grow

Nodes- Stems contain nodes and these are where leaves are attached. Stems have small nodes that usually become a bigger part of the plant.

Phloem- Transport solutions of nutrients and carbohydrates produced by Photosynthesis. Phloem is an important part of a plant because it carries nutrients to help the plant grow.

Plants- Plants are multicellular eukaryotes that have cell walls made of cellulose. They develop from multicellular embryos and carry out photosynthesis using the green pigments chlorophyll a and b. Plants grow all over the world creating a healthy environment and providing food

Root Hairs- Tiny cellular projections that cover the roots epidermal subsystem. Root hairs help the roots grow outwards, helping the plant collect more nutrients.

Sieve Tube Elements- The main phloem tubes. The sieve tube elements provide a passageway within the plant so particles can get through.

Tracheids- The first vascular plants new type of cell specialized to conduct water. Tracheids take care of water distribution throughout a plant.

Vessel Element- A type of xylem found in Angiosperms. The vessel element is yet another passageway for water and proteins to get around in the plant.

Xylem- A transport subsystem that carries water upward from the roots to every part of the plant. Xylem is needed in many plants because it is one of the main suppliers of water that is necessary for a plant to grow.
