Using strict modern definitions - none. The orbit of Pluto does cross inside the orbit of Neptune during part of it's journey around the sun, but Pluto is no longer officially a planet - it is a "dwarf planet" or "planetoid".
Plants don't orbit anything - planets do.
its orbit crosses with another plant
plants dont move!
The plant that takes the longest time to orbit the sun is the planet Venus, which, while not a plant, is often referred to in discussions about the solar system. Venus takes about 225 Earth days to complete one orbit around the sun. However, if considering plants specifically, there are no known plants that orbit the sun independently; they are all rooted to Earth and rely on its orbit around the sun for their growth and photosynthesis.
It takes one year for Earth to orbit the sun. Other planets have different orbital periods depending on their distance from the sun.
A plant's orbit is determined by the gravitational pull of the star or body it is orbiting, as well as its own velocity. The balance between the pull of gravity and the speed of the plant determines its orbital path.
another name for a young plant is an embryo
plant competitions is when a plant competes with another plant over who is tallest, who has the most water.
They grow on another plant so that they can obtain the nutrition from that plant. They are known as parasitic plants.
The pollen from one plant is spread, usually by wind or animal, to another plant. Then when the pollen gets to another plant, the other plant may reproduce.
by taking its nutriants from another plant
The shape of a plant's orbit around the sun is generally elliptical, meaning it is an elongated circle. This shape allows the planet to move closer to and farther away from the sun at different points in its orbit.
