Energy for the early growth of a developing bean embryo comes from
1 sunlight
2 water in the soil
3 food in the soil
4 leaves in the seed
Explanation:
D Energy for the early growth of a developing bean embryo comes from leaves in the seed vave cotyledon which store food material for provided to the developing or germinating embryo. The cotyledons become leaf of the seed after seed germination leaf take energy from sun. The seed also develop young cotyledon leaves which provide energy for the development of the embryo. Seed plants have developed an evolutionarily better way to protect their young generation from harsh environmental.

Dry seeds can induce higher temperature that the germinating seeds because
1 dry seeds have more reserve food
2 hydration makes the enzymes more sensitive to temperature
3 dry seeds are hard
4 the seedlings are tender
Explanation:
B Dry seeds induce higher temperature that the germinating seeds because hydration makes the enzymes more sensitive. Dry seeds are produced by those plants that usually produce pods capsules and seed heads. Seed germination is a process by which the embryo inside the seed will give rise to a plant. The seed coat is mainly composed of proteins that will be broken down by the enzyme poteases.

The form of pigment which inhibits germination is:
1 $\mathrm{P}_{760}$
2 $\mathrm{P}_{730}$
3 $\mathrm{P}_{650}$
4 all of these
Explanation:
C The seed germination is promoted by red wavelength $(650 \mathrm{~nm})$ and inhibited by far red $(730 \mathrm{~nm})$. This is due to the pigment phytochrome behaving in the following manner. Germination $\longleftarrow \mathrm{P}_{700} \rightleftharpoons \mathrm{P}_{\mathrm{sp}} \longrightarrow$ No germination

When a seed germinates, while fruit is still attached to plant
1 vivipary
2 scarification
3 germination
4 None of these
Explanation:
A When a seed germinates, while fruit is still attached to plant. This phenomenon is called vivipary. It is the phenomenon of germination of seeds inside the fruit while it is still attached to the parent tree, such adaptation is found in halophytes. Viviparous plants produce seeds that germinate before they detach from its parent.
