Leaf Anatomy
The tip of the leaf
What is the apex?
Living thing that makes its own food and does not need to consume another living thing to survive
What is producer?
An invisible gas that plants "exhale" into the air in the process of making food. Humans inhale this gas in order to breathe.
What is oxygen?
This is what roots are always looking for.
What are water and nutrients?
These do most of the work of absorbing water and nutrients for the plant.
What are root hairs?
This occurs when rain and wind carry soil away, changing the surrounding landscape. Roots help prevent this.
What is erosion?
This is a storage house that is made up of layers of leaves and a short stem. It is kind of like a seed since you can save it and plant it later. Onions, garlic, and tulips grow from this.
What is a bulb?
The outside edge of the leaf
What is the margin?
The process by which water is released from plants into the air
What is transpiration?
The green pigment found in all green plants which helps them produce food
What is chlorophyll?
This is how roots add to their length.
What is roots grow longer from the tip, adding cells to the end of each root?
The strongest part of the root. It is at the tip of the root. It is made up of a group of tough cells whose job is to push through dirt in search of moisture and nutrients.
What is the root cap?
Droppings of plant-eating animals such as cattle and horses. It is used by farmers to replenish the soil.
What is manure?
Literally means "earth plant". Each can be kept in a cool place for years then planted in the ground to grow. It has all the nutrients the plant needs to grow its roots and stems.
What is a geophyte?
The place where a leaf connects to the tree or the stem of the plant
What is petiole?
Plants that lose their leaves in the fall and winter
What are deciduous plants?
The invisible gas that plants need from the air to make food for themselves
What is carbon dioxide?
A root's special sense that tells it to turn and grow down in to the Earth.
What is geotropism?
One thick, main root growing down from the plant's stem. Carrots, turnips, and beets are examples of this.
What is a taproot?
This is the main way that nutrients get replenished into the soil naturally.
What is the decay of dead plants and animals?
These look like roots, but they are actually underground stems that store excess food. Instead of growing down like roots, they grow horizontally. They do NOT absorb water and nutrients for the plant.
What are rhizomes?
The entire leaf blade
What is lamina?
Several leaflets attached to a single petiole, which is attached to a plant
What is compound leaf?
Kind of food the plant makes
What is sugar?
This is the process of taking a healthy stem, branch, or even leaf from a plant and putting it in soil or water to grow into a new plant of the same kind. It is considered a clone or copy of the original plant.
What is rooting a plant?
This root system is made up of a series of roots growing in many directions. There may be a few roots that are thicker than others, but there is not one main root. This system is usually wider than it is deep.
What is a fibrous root system?
This is a type of soil that's made up of decayed plant and animal matter. You can buy it at the store or you can make your own by saving kitchen scraps, grass, dead leaves, and other plant matter from outside.
What is compost?
These are similar to bulbs but they do not have layers of leaves like bulbs. They are solid. They grow roots from the bottom. Like bulbs, they survive underground during winter and produce new plants in spring. A crocus is an example.
What are corms?
Banana shaped cells that expand and shrink to open and close the stoma of a leaf
What are guard cells?
Living thing that eats other living things to survive
What is consumer?
The tiny pores or "mouths" on leaf or other green part of a plant that take in gases to help make food for the plant
What are stomata?
These are the three main jobs of roots.
What are:
1)To absorb nutrients and water from soil
2)To anchor the plant in place
3)To prevent erosion
This root system is made up of one thick, main root with a number of smaller secondary roots branching off from the main root. This root system is deeper than it is wide.
What is a taproot system?
These are the three most important chemical elements that plants need from the soil.
What are nitrogen, phosphorus, and potassium?
These are underground stems that are swollen to form a big lump. They are packed full of starch. One example is a potato.
What is a tuber?
