Plants can move when their cells grow as a response to either light or gravity, which they are able to detect even as seedlings. This type of movement is slow and permanent. Other kinds of plants are capable of quick, momentary bursts of movement, which is due to hydraulics.Know More
Phototropism occurs when the pigment phototropin absorbs light. This pigment is present in the tips of plant shoots, which are the sources of directional growth in the plant. Once phototropin absorbs light, the growth hormone auxin is released, causing the cells of the plant to divide. Auxin directly responds to the direction of light, thus allowing the plant to grow where light is strongest.
Gravitropism, which also utilizes auxin, allows a plant to grow either toward or away from gravitational direction. This process is regulated by statoliths, or small packages of starch that are present in the shoot tips and roots of the plant. When the plant is tilted, the statoliths settle on whichever side gravity dictates. Auxin is then released in that direction.
Some predatory plants such as the Venus flytrap move as a response to physical stimulus. Tiny hairs cover the Venus flytrap's surface and allow the plants' cells to sense pressure. Once enough pressure is reached, chloride ions are released that allow an electrical signal to travel throughout the plant. This causes potassium ions to enter and exit cells. Water then follows, as parts of the plant function as levers.Learn more about Outdoor Plants & Flowers

To grow Brussels sprouts, plant the seedlings in the garden during midsummer, fertilize the soil 3 weeks after planting, pull any weeds out by hand and harvest the sprouts once they are 1-inch in diameter. If the sprouts are starting from seeds, plant them indoors 6 to 8 weeks before transplanting them outdoors.Full Answer >
If you are starting the okra seeds indoors, plant them three or four weeks before the last spring frost date for your area, and set them out when the seedlings are 6 weeks old. Otherwise, wait to plant okra until the soil has reached 65 degrees Fahrenheit.Full Answer >
To grow loofah seeds, choose a garden spot, place the seeds in trays and wait for the seedlings to germinate before planting them outside for further growth. You need a trellis or fencing, a plastic seed starter six-pack, a container, mulch and fertilizer to complete this project. Loofah seeds take roughly 140 to 180 days to fully mature.Full Answer >
