Describe the name and function of E

Style, a slender tube that connects the stigma to the ovary, captures and transports pollen to the ovary for fertilisation to occur.

Traits of water pollination

Less bright petals and scent, exposed anthers, and sticky and coated pollen.

Traits of animal pollination

large bright petals, nectar, and a sweet scent

Traits of wind pollination

Lightweight pollen, exposed anthers, feathery or sticky stigmas, and a large quantity of pollen produced.

What is required for germination.

Water, oxygen, optimal temperature, and moist temperature.
