During photosynthesis, plants use sunlight and carbon dioxide to..
to transform raw sap into Elaborate sap
Explain in which consists the Pollination?
The pollen travels from the anther of one flower to the stigma of the same or a different flower. A pollen grain reaches an ovule in the ovary and fertilisation
How seeds can be dispersed in different ways?
Seeds can be dispersed by birds, insects and other animals, wind or water.
Why ferns, angiosperms and gymnosperms are vascular plants?
Because they have tubes called vessels to transport water and nutrients around the plant.
Plants exchange gases through two different processes:
Photosynthesis and respiration
What happens with the oxygen and the carbon dioxide in the process of photosynthesis? And in respiration?
Photosynthesis = carbon dioxide is transformed into oxygen (during the day) | Respiration = like humans ( day at night)
Elaborated sap is the plant's food. It travels from the leaves to all parts of the plant through tubes called…
phloem vessels.
A stolon grows horizontally above the ground. True or False
True
How is called the tiny openings in the leaves ?
stomata.
Angiosperms produce.......
Flowers
Some plants reproduce using parts of themselves. They create a new plant from these parts. This is called
asexual reproduction.
How many types of plants which produce seeds are there?
Two - angiosperms and gymnosperms
The upper side of the leaves contains More or less chlorophyll than the underside?
More chlorophyll
The leaves contain a green substance called… and this traps…
Chlorophyll traps sunlight.
Raw sap travels up the stem to the leaves through tubes called……
xylem vessels.
Why do leaves change colour in autumn?
In autumn, there is less sunlight, the level of chlorophyll decreases and the ‘autumn colours’ can be seen.
What is the photosynthesis?
Is the process in which plants make their own food
Pollen can be dispersed in different ways. How is it?
Pollen can be transported by birds, insects and other animals or the wind.
