1) a -true
The apomictic seeds are the result of the apomixis( asexual production). with the help of these seed, the following vegetative plant organs are used in natural asexual propagation like tuber, rhizome, stolon, bulb etc.
2) a-true
stolons also known as runners are long horizontal stems which are sent outward from the base of the strawberry plant ;adventitious roots are formed at the nodes along the runner, which later results into new strawberry plant.
3) a- avacado
Recalcitrant seeds are those type of seeds which needs protection from certain elements like excessive drying out or freezing to remain viable.
4) a- true
In endospermic seeds, cotyledons are usually smaller or less developed. The cotyledon is part of the embryo that lies in the seed of a plant.
5) a- vermiculite
vermiculite is a natural occuring mineral which easily contain large quantities of air and water. It can also add excessive amount of nutient to the plants, including calcium and magnesium.
6) c- the brightness of light
photometric measurement of light is based on eye's photonic response. The human eye has different responses as a function of wavelength when it is adapted to light and dark conditions.
7) a- citrus
8) c- gymnosperms like pine and cedar
gymnosperms typically produce multitude of cotyledons , as few as 2 and as many as 24.
