Are leaf like structures that surround the base of the petals. What is this called?
The sepals enclose and protect the developing flower called a what? It opens as a fully formed flower.
The pistil, stamens, petals, and sepals re attached to the what? This is enlarged at the upper portion of a flower's stem.
This is the transfer of pollen from the anther to the stigma. What is this called?
This is the uniting of a sperm cell from a pollen grain with an egg cell in the ovary which leads to formation of a seed. What is this called?
Insects like bees, moths, and ants, along with bats and some birds are called this because they aid in pollination. What is this called?

This occurs when the ripened fruit bursts open and scatters the seeds some distance from the plant. What is this called?

composite family, head
One of the largest families of flowering plants is what?. A composite flower is actually many small flowers grouped together into a what?

Showy petal-like flowers surround the center. What is this called?
Most plans of this family, which is the third largest angiosperm family. This is called?

A plan with 5 white, pink or rose colored petals that form a cup-shaped blossom is a member of this family? What is it?
Usually have 5 rounded petals (or petal-like sepals) that form cup-shaped blossoms. What is this called?
These are common plants that often have a pleasant odor caused by oil in their leaves and stems. They are what?
The stems of mints are square and stout, and their flower clusters frequently form what?
Contains some of the most fragrant wildflowers. They are known for their sweet nectar. What are they?
These have clusters of small flowers arranged in umbels. What family is this?
Is an arrangement of flowers that have stems of nearly equal length, emerging from a common point on the main stem. What is this called?
Has unusual flowers arranged inn umbels. Every flower has 5 nectar horns, each consisting of a cup-like hood and a slender crest. What family is this?
Include the tiger lily, the lily of the valley, and the asparagus. What family is this?
A structure made of layers of think, fleshy leaves surrounding a very short stem. These store food during the growing season and allow plants to live after their flowers and above-ground leaves and stems have died. What is this called?
Most of these plants from this family contain 800 species and grow in warm areas or potted plants in colder climates.
Over half of the 800 amaryllis species grow from bulbs; the rest grow from this thick, vertical underground stem. What is is called?
Horizontal stems lying along or just under the ground. This is called?
The ovary of an amaryllis is what (attached below the other flower parts), instead of what (attached above the other flower parts) like the ovaries of the lilies and most other flowers. What are these two called?
A grass stem, or culm, is round and hollow except at the what? (The place where the leaf attaches to the stem).
The broad, flat portion of a leaf. What is this called?
Attaches the culm to the blade, is also a very important part of the leaf. What is this called?
A grass plant feature; creeping stem that grows along the ground. This is called what?
This is similar to a spike except that the flowers grow on small stems that branch off the main stem. What is this called?
Fertilized flowers produce grass fruits or what?
Most leaf blades attach to the node by a stalk called what?
The leaves of some plants, such as grasses, are called what? They have no petioles but instead attach directly to the stem by a sheath.
When two leaves grow from one node but on opposite sides of the stem. This is called?
Leaves are individual leaves - one for every node- that grown in an alternating pattern along the stem. This is what?
Consists of three or more leaves growing from the same node on the stem. What is this called?
A cluster of leaves growing around the base of a plant. This is called?
Have only one blade attached to a petiole. What are they?
Has more than one blade joined to a petiole and is called?
The blades of a compound leaf are called?
When all the leaflets attach at a common point on the petiole's tip. Think of them as fingers extending from the palm of your hand. This is called?
These, or edges, provide another way to distinguish between plants. Which is called?
Some leaves have margins that are smooth and unbroken or what?
With either small sharp teeth or large, blunt teeth leaf edges. This is called?
A leaf has extensions of itself (like your ear lobe) that can be blunt or end in a sharp point. This is called?
Known as a vein pattern. This is what?
The main veins seem to run parallel to each other usually along the length of the leaf. This is called what?
Has small veins branching from one man vein. This is called?
Has small veins branching from more than one main vein. This is called?
Because plants make their own food, they are called?
Animals and people who eat plants are called what?
As the sunlight enters the leaf's cells, some of the light's energy is absorbed by tiny structures inside the cell called what?
This is a green pigment of plants that is necessary for photosynthesis. This is called?
Enters the plan through this and the pores on the underside of the leaf to make it's food. This is called?
Simple sugar which provides the energy for the cells of living things. This is not stored but is called?
Most plants do not store glucose directly, instead, they usually converts excess glucose into this. What is it?
Is a carbohydrate found in the cell wall of plant cells. This is called?
Most dicots have this system in which the primary root grows straight down remains larger than the secondary roots that branch out from it. What is this called?
fibrous root systems
Monocots usually have this in which the primary root remains small and many slender secondary roots grow from it in all directions.
Plant reproduction that does not involve flowers, seeds, or fruit. What is this called?
The tip of a root consists of both an outer cap made from deal cells and an inner area of new growth cells that form immediately behind the cap. What is this called?
Growth in length is called this?
Growth in diameter is called this?
Develop from the sides of the root and force their way between soil particles to absorb necessary nutrients. This is called?
Is the continual movement of water from a solution of higher water content called?
Solution of lower water content and is a membrane that allows only certain molecules to pass through. This is called?
Tissue carries water and nutrients from the root hairs to the leaves This is called?
Tissue carries sugars from the leaves to the stem and roots to be stored is called what?
is the upward force that results as water enters the roots by osmosis. This is a what?
This is a tendency of water molecules to move up through a tiny space. This is called a?
As water is used up or lost, evaporation from the leaves, the cells need to replenish the supply. This is called?
