Living Beings/Nutrition in Plants
What are the five large groups of living beings/things?
Animals, plants, fungi, algae and protozoa, bacteria.
During respiration, what do plants take in and what do they expel?
How do most plants produce and what is the process?
Pollination, fertilization, seed and fruit formation and germination.
Describe the process of fertilization in plants.
The pollen grain falls on the stigma , which is part of the pistil. There he joins the ovum to form an embryo and fertilization occurs.
True or False: All algae and protozoa are visible to the naked eye.
False
Can you give an example of a fungi?
Mushrooms
During photosynthesis, what do plants take in and produce as waste?
Plants take in carbon dioxide and produces oxygen as waste.
When does pollination occur?
When pollen from the stamen of a flower is transported to the pistil of another flower of the same type.
Describe the process of seed formation and the fruit.
The embryo transforms into the seed. The pistil, at the same time, starts to grow and transform in the fruit and it contains the seeds.
During photosynthesis, what substances make up the brewed sap?
The mix of food produced with the water.
What are the three vital functions of plants?
Interaction, reproduction and nutrition
Plants breathe all the time, but they only photosynthesize when there is what?
Solar light
What are the ways pollen can be carried?
Animals, water or wind.
Describe germination.
Ripe fruits fall to the soil and the germ is produced - germination of a seed, which with water and adequate temperature, gives rise to a new plant.
During photosynthesis, what substances make up the raw sap?
water and mineral salts
Where do plants absorb water and mineral salts?
The roots.
Do plants have sense organs?
No
What do plants produce to attract animals?
Nectar
What is a habitat?
Student's own answer.
What is wind pollination?
Wind carried pollen from some flowers to others.
Where does photosynthesis take place?
In the leaves.
What are the factors that plants react to in their environment?
Light, water/heat and physical contact.
Why are some flowers so colourful and beautiful?
To attract the bees.
Can you give an example of behavioural adaption?
Eg. Hibernation in winter.
