Plant Parts & Their Jobs
This part of the plant makes food using sunlight, water, and carbon dioxide.
What is the leaf?
Put these stages in the correct order: adult plant, seedling, seed, young plant.
Seed → Seedling → Young Plant → Adult Plant
Seed dispersal means seeds move away from this plant.
What is the parent plant?
Seeds that are small, fluffy, light, or have wings are usually dispersed this way.
What is wind dispersal?
This part develops from a flower and contains seeds.
What is a fruit?
These plant parts anchor the plant in the soil and absorb water and minerals.
What are the roots?
This contains a tiny baby plant and can grow into a new plant.
What is a seed?
One reason for seed dispersal is that it allows seeds to spread to these.
What are new places?
A coconut can float and has a waterproof outer covering. Which method of seed dispersal does it use?
What is water dispersal?
This scientific term means the process of producing new living things.
What is reproduction?
This part supports the plant and transports water and food around the plant.
What is the stem?
This is when a shoot and first root begin to grow from a seed.
What is a seedling?
Seed dispersal helps seeds find these so they can grow successfully.
What are suitable conditions?
Burrs have hooks or tiny spikes that can attach to fur or feathers. Which method is this?
What is animal dispersal?
This is the transfer of pollen from one flower to another flower.
What is pollination?
This part helps the plant is part of reproduction and helps produce seeds and fruits.
What is the flower?
A growing plant that develops more leaves, roots, and a stronger stem.
What is young plant?
Why is it a problem if seeds grow too close to the parent plant?
They may compete with the parent plant for water, light, space, and nutrients.
When a dry, ripe seed pod splits or bursts open and sends seeds away, this method is taking place.
What is explosion dispersal?
The sticky top part of a flower that receives pollen.
What is the stigma?
A flowering plant has these two main systems.
What are the shoot system and root system?
What is germination, and what two things does a seed need the right amount of to germinate?
Germination is when a seed starts growing into a new plant. It needs water and warmth.
Two seeds begin to grow. Seed A is directly beside the parent plant. Seed B is farther away in an open area. Which seed may have a better chance of growing successfully, and why?
Seed B, because it has more space and is less likely to compete with the parent plant for the things it needs to grow.
Match all four: dandelion, coconut, burr, pea pod with their method of seed dispersal.
Dandelion – wind; Coconut – water; Burr – animals; Pea pod – explosion
This happens when the male and female parts of a flower join to make a seed.
What is fertilisation?
