Frond- a big leaf that is divided into many different parts. As you can see in this picture, this leaf is divided into several different parts.

C4 plant- fixes CO into a compound and it has four carbon atoms. the compound later enters the Calvin cycle of photosynthesis. Some types of C4 plants are crabgrass, sugarcane, and corn.

Xylem- one of the two types of tissues in vascular plants that transport nutrients, the stems of plants are the main transporters of nutrients in plants

Long Day Plant- a plant that flowers only after being exposed to light periods that are longer than a certain critical length, such as summer. An example of a long day plant is a potato.

Ethylene- an organic compound with the formula C2H4. It is classified as an unsaturated hydrocarbon. It is the most produced organic compound in the world, and it is widely used in the industry. It is found in salt.

Hydrophilic- a substance capable of interacting with water through hydrogen bonding. Hydrophilic molecules usually have polar groups that enable them to dissolve in the water. Salt is able to dissolve and interact with water.

 Eukaryote- any organism that has cells with complex structures inside its membranes. All living animals, humans, and most types of plants are considered eukaryotes while bacterias are considered to be prokaryotes.

Gibberellins- plant hormones that regulate growth and influence various developmental processes. Some of these processes are stem elongation and germination. Since it helps with stem elongation, gibberellins are found in plant stems.

ATP- used for many cell functions including transport work moving substances across cell membranes. It is used in plants to transfer energy.

Calvin Cycle- a process that occurs during photosynthesis. It occurs when the light energy is used to convert carbon dioxide and water into organic compounds that can be used by the organism for food.
