Questions and Answers

Observe the process of fertilization in plants and changes that take place in a flower after fertilization. Conclude and explain your observation.

The process of fertilization in plants occurs when a pollen grain from a flower is transferred to a stigma, and the pollen tube grows down the style and reaches the ovary at the bottom of the pistil. Once the tube reaches the ovary, it releases sperm cells that fertilize the ovules which develop into seeds. Changes in the flower occur after fertilization, such as the petals/stigmas falling off (withering) and the swelling of the ovary to form the fruit.

What is friction?

Friction is a force that opposes motion between two surfaces in contact.

List 2 examples of friction in our daily lives.

Walking on the ground and rubbing your hands together are examples of friction in everyday life.

Flashcards

Fertilization in plants

The process by which a male gamete (pollen) fuses with a female gamete (ovule) in a flower, leading to the formation of a seed.

Changes after fertilization

Changes that occur in a flower after fertilization include: petals wither and fall off, ovary develops into fruit, ovules develop into seeds.

Friction

Friction is a force that opposes motion between two surfaces in contact.

Is friction good or bad?

Friction can be beneficial in many situations, such as providing grip on surfaces, enabling brakes to work, and creating heat. However, it can also be detrimental, causing wear and tear, reducing efficiency, and generating heat.
