Phloem

Phloem is a vascular tissue that drives sugars and other products downward from the leaves. It carries organic nutrients such as sucrose. The picture above shows the phloem of a pile of plants.

Parenchyma cells

Parenchyma cells are cells that cover the internal layers, outer layers, and innermost layers. They have extensive spaces between the cells. It also forms the soft tissue of fruit. The picture above shows how parenchyma cells look like.

Mycorrhizae

Mycorrhizae is a fungus root. This picture above shows a dead plant with dead roots. They act poorly without spores or hyphae of mycorrhizal fungi.

Modified leaf of a plant

A modified leaf of a plant is a plant that is modified for several different functions. The sepals, in the picture above, modified the structure of the flower. The leaves at the base of the flower is a good example.

Long-day plant

Long-day plants, or sometimes called "Chrysanthemums" are just plants that flower during the summer. Spinach, which is the picture shown above, is an example of a long-day plant because it flowers during the summer. They become forming buds when the days are longer than their day length. Another example could be lettuce and petunia.

Lichen

A lichen is an organism that comes from algae or cyanobacteria living among filaments of a fungus. It's like fungus that grows on trees due to humidity and/or rain. They are really easy to find. They come in very different properties and they come in many, different colors, sizes, and form. The picture above is a lichen.

Kinesis

Kinesis are the changes in activity level of an animal that are dependent on stimulus strength. Cockroaches, as shown above, can be a great example for kinesis. For cockroaches, a stimuli would be light. When you flash a light on a group of cockroaches, they would not move forward or away, they would just scatter around the energy. The stimuli cause their movement to be completely random.
