Directional response that allows plants to grow towards, or in some cases away from a source of light

The regulation of physiology is development in response to day length.

Phototropins are the main protoreceptors responsible for ______?

Palnts that flower only when day length drops below a certain threshold are called .

Plant that flower only when day length rises above a certain threshold are called?

Seeds or seedlings for promoting early flowering is know as ____?

Fruits produce gaseous compound is called.

Pathogens causing fruit drop are also responsible for?

Fruit damage are cause by ?

The green pigments that captures light for photosynthesis

Chlorophyll pigments harvest energy ( protons ) by absorbing certain wavelengths

Main factors affecting photosynthesis except

Different colours of light can affect how much photosynthesis can occur

The more light a plant absorbs, the more photosynthesis can occur.

Not only cause the plant to wilt but also limits the quantity of carbon dioxide.

Radicle surrounded by protective sheath is called?

Outer layer that protect embryo

The shoot emerges out of the soil in search of light to start photosynthesis.

State of suspended growth .

State of suspended growth .

It is process where pollination is required but no fertilization takes place.

The physiological process of fruit drop is called?

It is characterized by substantial increase in ethylene production and respiration coincident with the onset of repining

It is a major bottleneck causing reduction in yield and quality of harvested produce.

It produce by the developing seeds which is exported to the wall of the ovary and causes rapid expansion of each of the cells.

It produce by the developing seeds which are hormones that are exported from seed and cause cell division in the ovary wall.

The mother plant is producing another hormone, _______ which causes bthe embrayo in the developing seeds to become dormant.

Bulbs have a rounded shape, narrower towards the top, and a flat base called?

It stimulates the onion plant to stop making a bulb and begin sending up flower shoots and forming seeds called bolting

It is a process in which plant meristems become mostly inactive to withstand harsh environmental conditions

It occurs due to chemical changes with in the seeds embryo

It is caused by conditions outside of the seeds embryo

Allows seed to overcome periods that are unfavorable for seedlings established and is therefore important for plant ecology and agriculture.

It is the male reproductive organ of flower.

It is the part of the flower that has most variation from plant to plant

It is the female reproductive organ of a flower

Plants contain ________ in the leaves which convert the energy from sun light, carbon dioxide ,and water into sugar , which they use as food.

These are important indicators of the adaptive evolution of seed germination.

It is the exterior part of a flower that protect the interior while it emerges.
