Hormones like auxins and cytokinins travel only through the roots, allowing for downward movement of signals.

Ethylene hormone is transported through the flowers to promote fruit ripening in distant parts of the plant.

Hormones like gibberellins move through both the xylem and phloem, enabling regulation of growth and stress responses.

The movement of all plant hormones is restricted to individual cells.

Thigmotropism

Hydrotropism

Phototropism

Gravitropism (Geotropism)

By climbing the mango tree, the orchid can reach sunlight needed for glucose production.

By climbing the mango tree, the orchid can self pollinate.

By climbing the mango tree, the orchid has access to fruits for nutrients.

By climbing the mango tree, the orchid can access nutrient rich soil.

Based on external factors such as gravity, the leaves are pulled down based on their weight.

Based on stimulus, hormones are absorbed by the roots and transported to the leaves for a response.

Based on stimulus, hormones are transported through the vascular bundle signaling leaves to close.

Based on internal factors, hormones are destroyed causing the leaves to wilt (close).

Carbohydrates produced for the absorption of water from the paper towel.

Carbohydrates produced for the storage of energy molecules causes the stem to bend.

Hormones produced as a response to geotropism cause root system to grown down.

Hormones produced as a response to thigmotropism cause the bean to dry out.

Pollen from the anther falls onto the stigma of the same plant.

Ovules from the ovary fall onto the filament of the same plant.

Pollen from the anther falls onto the stigma of a different plant.

Ovules from the ovary fall onto the filament of a different plant.

Pollen from the anther is transferred onto the stigma of a different plant.

Ovules from the ovary fall onto the filament of a different plant.

Ovules from the ovary fall onto the filament of the same plant.

Pollen from the anther is transferred onto the stigma of the same plant.

Pollen from the male anther lands on the stigma, travels down the style, and fertilizes the ovule in the ovary, which then develops into a fruit.

Pollen grains fertilize the ovary immediately upon contact, causing the petals to fall off and the fruit to form.

The stigma directly absorbs pollen from the environment, triggering the ovary to produce seeds and fruit without fertilization.

The ovule releases pollen to attract the anther, allowing fertilization to occur inside the petals, which later turn into the fruit.

The direction of light is detected by cells on the shoot tips, and plants respond by bending towards the light.

The direction of light is detected by cells on the shoot tips, and plants respond by producing chlorophyll.

The direction of light is detected by cells within the roots, and plants respond by bending in the direction of gravity.
