What is the process of germination in a flowering plant?
When a plant produces seeds for the next generation
100
What is the process of fertilization?
When the male cell joins with the female cell in the OVARY to make a seed.
100
What is pollination?
Helps flowers make new seeds. Flowers make seeds so they can grow into new plants.
100
Which plant structure is this?
Sepal
100
What is seed dispersal?
When a plant spreads its seeds around so that new plants can grow in different places.
200
After a seed germinates, what happens next?
A tiny plant called a seedling emerges from the soil.
200
What is the first step of fertilization?
Pollen grain lands on the pistil (female structure).
200
How do animals play a part in pollination? Use an example of an animal.
Animals often play a part in pollination. Animals that transfer pollen are called pollinators. Such as a bee.
200
How do the ovary and pistil work together?
The ovary and pistil work together like a team to help flowers make seeds and grow into new plants.
200
How do animals play a role in seed dispersal?
As animals go from one place to another, they disperse seeds.
300
Can seeds germinate without soil?
Yes
300
What is the second and third step of fertilization?
2nd: A thin tube grows down through the pistil to the ovary
3rd:The sperm cell of the pollen combines with the egg cell
300
What two structures are used when pollen is transferred from the male reproductive system to the female reproductive system?
The stamen is transferred to the pistil.
300
What is the function of stigma?
It is the sticky bulb that you see in the center of flowers, and it is the part where the pollen lands and starts the fertilization process.
300
Justify why plants need to use seed dispersal.
If all of the seeds just stayed in one place, the new plants would have to compete with each other for sunlight, water, and nutrients.
400
What are some factors that can affect seed germination?
Amount of water, air, and temperature.
400
If there are no pollinators during fertilization, what will happen?
Plants will not be able to form more seeds. Which will cause less plants.
400
What two things transfer pollen?
Wind and water.
400
What is the function of the ovary, and describe what it looks like?
The ovary is the female reproductive organ of the flowering plant. It looks like a small ball or bulb.
400
What are the ways seeds can disperse?
Wind, animals, water
500
What is the process of photosynthesis, and how does it relate to seedling growth?
Seedlings need photosynthesis to grow because they're just starting out and they need lots of energy to grow bigger and stronger. Without photosynthesis, seedlings wouldn't have enough food to grow properly and they could even die!
500
What process happens after pollination and before seed dispersal
Fertilization
500
Sometimes animals have a role in plant reproduction. In which two stages of the plant life cycle?
Pollination and Seed Dispersal
500
How do internal and external plant structures work together?
Internal and external plant structures work together like a team to help the plant stay healthy, make food and reproduce. Just like how we need different parts of our body to work together to stay healthy and strong!
500
How do pollination and seed dispersal work together?
Pollination and seed dispersal work together to help plants make more plants and spread their seeds to new places.
