gibberellins

Gibberellins are plant hormones that regulate growth and influence various stages of the developmental process. Gibberellins are found in all plants as they are growing, like the plant pictured above.

Cellular respiration

Cellular respiration is the metabolic process where certain organisms obtain energy from organic molecules. It takes place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported into the lungs. Plants like these flowers on my porch go through the process of cellular respiration.

ATP

ATP is a nucleotide that occurs at the mitochondria and the chloroplasts of plants. It is used as a source for cellular reactions. This plant in my yard contains ATP in its cells.

Mating Behavior

Mating behavior is the behavioral interactions between organisms for the purpose of mating. Male peacocks spread their colorful tail feathers, like this one I found at a peacock farm, to attract female peacocks.

meristem

Meristem is the region of cells capable of division and growth in plants . It's usually at the tip of the stem or root of a plant. This plant in my backyard has meristem plant tissue in it.

Stigma & style of carpel

The carpel is an organ at the center of the flower  that holds ovules in an ovary. It consists of a stigma, which is at the tip of the carpel, and is receptive to pollen. It also has a style, which connects the stigma to the ovary. My thumb is pointing to the carpel of this flower. 

r-strategist

R-strategists are organisms that live in unstable environments and reproduce rapidly in order to survive. They are part of the R-selection reproduction group. Because of low diversity and the lack of resources where these organisms live, their population size diminishes rapidly. Weeds like these under my porch are examples of an r-strategist.
