Review your understanding of plant reproductive success in this free article aligned to NGSS standards.
Key points:
- A plant that has more surviving offspring typically has a higher reproductive success.
- Certain animal behaviors can help increase a plant’s reproductive success. For example, pollinators are animals that help flowering plants reproduce through pollination.
- When pollinators feed on flowers, they transfer pollen from male to female flower parts. This can lead to fertilization, and the production of new offspring for the plant.
- Many plants have special features to attract pollinators. For example, a flower’s scent may attract pollinators.
- Animals can also help with seed dispersal, or the movement of seeds away from a parent plant. Seed dispersal increases the chance that a seed will grow in an area with plenty of resources.
- Many plants have special features to help with seed dispersal. For example, some seeds have structures that help them stick to an animal’s fur. This allows the seeds to be carried to a new area.

I'm so glad I'm contributing to nature, by blowing my share of dandelions in exchange for the small small price of a wish:)(15 votes)
I don't understand this part. May I please receive an explanation for this part?(5 votes)
Plants reproduce by pollinators and by seed despersal which means that bees,bats,and other pollinators carry pollen from plant to plant, this causes plants to create offspring (or plant children) then they do seed despersal which is where the plants seeds get sent far away. Normally the seeds get blown far away, the seeds are carried by birds, and even humans can cause seed despersal. Does this explanation help?(10 votes)
What happens when one of the animals traveling the pollan get killed by another animal.(3 votes)
Then the pollen would not get to a plant, making the pollen useless (unless some other thing carried the pollen to the plant after it fell)(4 votes)
- Can plants reproduce using sexual reproduction?(3 votes)
Plants are living organisms. That means they need to reproduce in order to pass on their genes to future generations. Plants can create offspring through either sexual or asexual reproduction.
Hopes it helps explain your answer. :[(2 votes)

I have a question, how can dandelions land somewhere and reproduce?
Can someone tell me?(0 votes)
Dandelions have several mechanisms for dispersing their seeds so they can land in different locations and reproduce.
One of the most common methods of seed dispersal in dandelions is the wind. Dandelion seeds are very lightweight and have a fluffy parachute-like structure called a pappus that allows them to be carried long distances by the wind. When the dandelion flower dies, the pappus extends out from the base of the flower, allowing the seeds to be carried by the wind to new locations.
Dandelions can also use animal dispersal to propagate. They produce small, nutritious fruits that can attract animals such as birds, squirrels, and other small mammals. When these animals eat the fruits, the seeds pass through their digestive system and are excreted elsewhere, allowing the dandelions to spread to new areas.
Additionally, dandelions can also use self-dispersal. As the dandelion flower begins to fade and dry out, it produces a stem that elongates and coils up, forming a "clock" or "blowball." When the clock is mature, it can be blown on by the wind, causing the seeds to be released from the base of the pappus and scattered in the surrounding area.
Overall, dandelions have several effective methods of seed dispersal, allowing them to land in new locations and reproduce.(3 votes)

UwU (ˈuːwuː ) exclamation. slang. an expression of admiration for something that is considered cute, used esp in text messaging and social media.(2 votes)
- how would seeds get pollinated if you pooed it(1 vote)
An animal, say a bird, will eat a fruit that for example, contains a seed. and then, while they are flying, they might poop. then this poop falls to the ground. And if it landed in a sustainable environment, it will grow eventually.(0 votes)
