Branching roots primarily found in grasses
Fibrous roots
One main root found in plants such as carrots or dandelions. It stores food.
Taproot
Works much like a solar panel, absorbing light energy, which is then stored as food energy. It uses the sun's light energy to change carbon dioxide & water into food.
Chlorophyll
The food produced by a plant. A type of sugar.
Glucose
The process of using oxygen to release energy from food.
Cell Respiration
A growth response of a plant to conditions in the environment such as light or water.
Tropism
A turning of the roots towards the Earth. This ensures that roots will grow down in the soil where water and nutrients are.
Geotropism
Growing towards light.
Phototropic response
Growing towards water.
Hydrotropic response
Response to touch such as when tendrils wrap around objects to support the plant.
Thigmotropism response
The layer of the root that connects the epidermis with the inner core.
Cortex
This tissure is made of tubes that carry water and minerals from the soil upward.
Xylem tissue
This layer of cells covers the root
Epidermis
This tissue is made of tubes that carry sugars and other nutrients from the leaves through the stem and down to the root.
Phloem tissue
These are tiny extensions that take in water and minerals to the root.
Root hairs
The tip of the root, pushes the root through the soil.
Root Cap
The outer covering of the woody stem
Bark
The center of a woody stem.
Heartwood
A part of a woody stem
sapwood
The part of the woody stem that becomes thicker each year.
Growth layer
Plants such as pine, spruce & fir tree have these leaves. The shape of the leaves helps reduce water loss.
Needle leaves
These leaves have veins, blades & petioles.
Broad leaf
The transport system with the petiole in the leaf. Water enters the leaf through this part.
Vein
The broad flat part of the leaf.
Blade
The extension of the xylem and phloem tubes of the stem.
Petiole
List the parts of the leaf.
Upper epidermis
Palisade layer
Spongy layer
Vein
Lower Epidermis
Describe the process of photosynthesis.
Carbon dioxide + water + light energy = glucose + water
