Pollination, fruits and seeds
What is the name of the process where pollen is transferred from the anther to the stigma? (Germination, Fertilisation, Dispersal, Pollination)
Pollination: This is the correct term for the movement of pollen from the male part (anther) to the female part (stigma).
A dandelion seed has a fluffy 'parachute'. What is its most likely method of dispersal?
By wind
What is 'seed germination'?
When a seed starts to sprout and grow into a new plant.
What is the main feature of a 'flowering plant'?
It produces flowers to reproduce.
Which part of the flower is designed to be sticky to catch pollen? (Anther, Sepal, Petal, Stigma)
Stigma: The stigma is the receptive tip of the female part, and it is often sticky to trap pollen grains.
A coconut has a hard, waterproof shell and a fibrous husk that helps it float. How is it dispersed?
By water
What are the three main conditions that most seeds need to germinate?
Water, warmth, and air (oxygen)
Which of these is an example of a non-flowering plant? (A sunflower, A fern, An apple tree, A rose bush)
A fern
After successful fertilisation, which part of the flower develops into the fruit?
The ovary; its wall swells and ripens to become the fruit, which protects the seeds inside.
Why is it important for seeds to be dispersed far away from the parent plant?
So the new plants get enough light, water, and nutrients.
What is the main role of water in germination?
It softens the seed coat and activates the embryo.
How do non-flowering plants like ferns and mosses reproduce?
By producing tiny, dust-like spores.
A plant has small, dull-coloured flowers with no scent but produces large amounts of light pollen. How is it most likely pollinated?
By the wind (These features (small, dull, no scent, lots of light pollen) are all adaptations for wind pollination.)
A sycamore seed has a 'wing' that makes it spin as it falls. This is an adaptation for which type of dispersal?
Wind
A student plants a bean seed in a pot of dry soil and leaves it in a warm, sunny window. Why will it probably NOT germinate?
It has no water.
What do all non-flowering plants have in common?
They do not produce flowers.
What is the main purpose of a fruit?
To protect the seeds and help disperse them
Which of these is NOT a method of seed dispersal? (Wind, Water, Pollination, Animal)
Pollination
What is the main job of the seed coat?
To protect the embryo and food store.
